The rotor balance is an important basis for maintaining stable operation of the aeroengine, when unbalance occurs to the rotor of the aeroengine, the unbalance position and the unbalance amount are calculated and analyzed through special equipment, and the rotor vibration parameter meets the design index requirement under the working condition through a certain technical means. At present, a common and effective means in the industry is to change the mass distribution of the rotor by adopting a method of removing rotor materials or adjusting weights, so that the vibration of the rotor caused by eccentric centrifugal force or the vibration force acting on the bearing and consistent with the working rotation speed is reduced to be within a specified allowable range, and the purpose of stably operating the rotor system is finally achieved.
Repeated weight testing by weight screws on the weight face of the rotor is the most common technique. During actual operation, the engine is disassembled firstly, the engine rotor is disassembled step by step from the outer casing and the inner casing of the engine to the engine rotor if necessary, the assembly screws are installed on the corresponding rotor counterweight surfaces, and then the unit body is installed on a special dynamic balancing machine, and then the trial weight operation is repeatedly performed. However, this type of operation often requires a long disassembly and assembly time. In addition, for the multi-duct engine, the overall structure of the engine is increasingly complex due to the multi-duct design or the multi-regulation structural design, and the original assembly clearance of components can be damaged due to the repeated disassembly and assembly of the engine, so that new risks are brought, the maintenance time is further prolonged, and the flight plan of the aircraft is influenced.
In order to solve the problems, the embodiment of the invention provides an engine rotor balancing system, which aims to solve the problems that the existing engine rotor needs to consume longer disassembly time and assembly time when performing test counterweight. It is achieved that the engine rotor is subjected to trial weighting to achieve rotor balance without dismantling the engine body parts. It should be appreciated that the engine rotor may be an engine rotor contained within an aircraft engine.
Fig. 1 shows a schematic configuration of an engine according to an exemplary embodiment of the present invention. FIG. 2 illustrates an enlarged view of an engine rotor balancing system according to an exemplary embodiment of the present invention. As shown in fig. 1, an engine according to an exemplary embodiment of the present invention includes an engine rotor 100, an outer casing 200, and an inner casing 300 disposed at a rear portion of a blade root of a rotor blade, and an engine rotor balancing system includes a porous balancing device 400, a pneumatic transfer device 500, a controller 600, and a weight 700, and the engine rotor is further connected to the controller 600. Fig. 3 shows a schematic structural view of a porous balancing device according to an embodiment of the present invention. As shown in fig. 2 and 3, the cellular balancing apparatus 400 includes a fixed disk 410 and a plurality of locking mechanisms 420 for locking the weight 700, the fixed disk 410 is provided on the weight surface of the engine rotor 100, the plurality of locking mechanisms 420 are uniformly provided along the circumferential direction of the fixed disk 410, and the controller 600 is communicatively connected to each locking mechanism 420 and the pneumatic transportation apparatus 500, respectively.
For convenience of installation, the fixing disc 410 may be a fixing disc, the weight surface of the engine rotor 100 may be a disc surface of the engine rotor 100, and the plurality of locking mechanisms 420 may be disposed on the surface of the fixing disc 410 and uniformly disposed along the circumferential direction of the fixing disc 410, and the number of the weight members 700 may be plural.
On this basis, as shown in fig. 1, the pneumatic transportation device 500 according to the embodiment of the present invention has a transportation channel 510 for transporting the weight 700, an inlet of the transportation channel 510 communicates with an external area of the engine, an outlet of the transportation channel 510 is opposite to a surface of the fixed disk 410 provided with a plurality of locking mechanisms 420, the plurality of locking mechanisms 420 are located between the outlet of the transportation channel 510 and the fixed disk 410, and the controller 600 is used for controlling the outlet of the transportation channel 510 to be opposite to a position of a locking cavity of one of the locking mechanisms 420. That is, the controller 600 may control the outlet of the transfer channel 510 to be positioned opposite the locking cavity of any one of the locking mechanisms 420 contained in the porous balancing device. The outer casing 200 has a first hole 201 through which the transfer channel 510 passes, and the inner casing 300 has a second hole 301 through which the transfer channel 510 passes.
Illustratively, the controller 600 is provided with an engine rotor imbalance analysis program and a dedicated database that collects a plurality of amplitude/phase angle and corresponding rotational speed historical data. The engine rotor unbalance analysis program can utilize the aircraft airborne test equipment or the engine complete machine bench test equipment to compare with historical data according to vibration data monitored by an engine airborne data acquisition system, comprehensively analyze rotor unbalance parameters and counterweight parameters, analyze unbalance positions and unbalance amounts and formulate a balance scheme. Then the mass distribution of the rotor is changed by utilizing a method of adjusting the counterweight, so that the vibration of the rotor caused by eccentric centrifugal force or the vibration force which acts on the bearing and is consistent with the working rotation speed is reduced to be within a specified allowable range, and the aim of stably operating the rotor system is finally achieved. That is, the weight parameters are determined by vibration data monitored by the system. For example: the weight parameters may include the number of weights and the corresponding target weight position for each weight, the target weight position being a locking cavity of a locking mechanism that is required to be filled with weights.
In particular, since the inlet of the transfer channel 510 is in communication with the external region of the engine, the outlet of the transfer channel 510 is in communication with the internal region of the engine, and the outlet of the transfer channel 510 is opposite to the locking cavity of any one of the locking mechanisms 420 included in the porous balancing device 400. When the engine rotor 100 needs to be weighted, the controller 600 is utilized to start the engine rotor 100 to rotate according to the weight parameters, so as to drive the fixed disc 410 and the locking mechanisms 420 to rotate simultaneously, so that the target weight locking mechanism is opposite to the outlet position of the transfer channel 510 and is in a coaxial state. At this time, the controller 600 may control the transfer passage 510 to transfer the weight 700 in the external region of the engine to the outlet of the transfer passage 510, and then control the pneumatic transfer device 500 to provide pneumatic pressure to the inlet of the transfer passage 510 by using the controller 600, so that the weight 700 enters the locking cavity of the target weight locking mechanism under the action of the pneumatic pressure. The controller 600 then continues to control the target counterweight locking mechanism to lock the counterweight 700, thereby completing the rapid balancing of the engine rotor 100.
On this basis, when the counterweight to be removed in the weighted locking mechanism needs to be removed, the controller 600 may be used to control the engine rotor 100 to rotate, so as to drive the fixed disc 410 and the plurality of locking mechanisms 420 to rotate simultaneously until the position of the counterweight to be removed coaxially faces the position of the outlet of the transfer channel 510. At this time, the controller controls the locking mechanism for locking the weight to be removed to be opened, and simultaneously, the controller controls the pneumatic transfer device 500 to provide pneumatic suction force to the inlet of the transfer channel 510, so that the weight to be removed enters the transfer channel 510 under the action of the pneumatic suction force, and then the weight to be removed is transferred to the external area of the engine, and the rapid balancing of the engine rotor 100 can be further completed.
In one example, the target weight locking mechanism is a locking mechanism that needs to be weighted, and the target weight locking mechanism may be one or more. When a plurality of target locking mechanisms need to be weighted, one of the target locking mechanisms can be weighted first, and then the controller is used for controlling the engine rotor to rotate, so that the position of the target locking mechanism to be weighted next and the position of the outlet of the transfer channel 510 are coaxially opposite, the next target locking mechanism to be weighted can be weighted, and the other target locking mechanisms to be weighted can be weighted similarly, so that the rapid balance of the engine rotor 100 is realized.
In another example, the weight to be removed needs to be removed, and the weight to be removed may be one or more. When the number of the weight pieces to be removed is plural, one weight piece to be removed may be removed first, and then the controller is used to control the engine rotor to rotate, so that the position of the weight piece to be removed next is coaxially opposite to the position of the outlet of the transfer channel 510, so that the weight piece to be removed next may be removed, and so on, the other weight pieces to be removed are removed, thereby realizing further rapid balancing of the engine rotor 100.
In an alternative, FIG. 4 illustrates a front view of a porous balancing device of an embodiment of the present invention. As shown in fig. 3 and 4, each locking mechanism 420 of the present embodiment includes a locking member 421 and an actuating mechanism 422 in communication with the controller 600, the actuating mechanism 422 being in communication with the locking member 421. It should be appreciated that the actuator 422 may be a wireless actuator or a wired actuator, as not limited herein. The actuating mechanism 422 is used to control the locking and unlocking of the locking member 421. For easy installation, a plurality of mounting holes may be formed in the surface of the fixed disk 410 in the circumferential direction, and each locking mechanism may be mounted to the fixed disk 410 through the mounting holes.
For example, as shown in fig. 4, N holes are formed on the surface of the fixed disk 410 and disposed along the circumferential direction of the fixed disk, and each hole is designed with N locking members 421, i.e., N locking members 421, each locking member 421 is connected to one actuating mechanism 422, and the actuating mechanisms 422 are also N. A wired connection may be used between the actuating mechanism 422 and the locking member 421, with the actuating mechanism 422 controlling the opening or locking of the locking member 421. When the actuator 422 is a wireless actuator, wireless signal transmission is adopted between the wireless actuator and the controller 600. The actuating mechanism 422 is driven by a signal to open or close the locking mechanism, so that the counterweight 700 is locked or unlocked, and the problem that the counterweight 700 is not firmly locked is prevented.
In particular, when it is desired to weight the engine rotor 100, the weight 700 enters the locking cavity of the target weight locking mechanism under the action of pneumatic pressure. At this time, the controller may control the actuating mechanism included in the target weight locking mechanism to lock the locker, thereby locking the weight 700. When the weight of the engine rotor 100 needs to be reduced, the controller can control the actuating mechanism contained in the locking mechanism where the weight to be removed is located to open the locking member, at this time, the weight to be removed is sucked out of the engine under the action of pneumatic suction force, and is transported to the outside of the engine by using the transport channel 510.
In an alternative form, FIG. 5 shows a schematic structural view of a retaining member according to an embodiment of the present invention. Fig. 6 shows a side view of a retaining member according to an embodiment of the invention. As shown in fig. 5 and 6, each locking member 421 includes a tapered connector 4211 and an openable clamping portion 4212 connected to the tapered connector 4211, the connector 4211 is fixedly connected to the fixed disk 410, and the actuating mechanism 422 is communicatively connected to the openable clamping portion 1212. For convenience of use, the openable and closable clamping portion 4212 may be configured as a three-leaf openable and closable clamping portion, and the three-leaf openable and closable clamping portion may be in a split structure, and the conical connecting member 4211 is mounted on the fixed disk 410 through the mounting hole, and may be welded in other manners, so as to be firmly connected in one period.
In particular, when it is desired to weight the engine rotor 100, the weight 700 enters the locking cavity of the target weight locking mechanism under the action of pneumatic pressure. At this time, the controller may control the actuating mechanism included in the target weight locking mechanism to lock the openable and closable clamp portion 4212, thereby locking the weight 700. When the weight of the engine rotor 100 needs to be reduced, the controller can control the actuating mechanism contained in the locking mechanism where the weight to be removed is located to open the openable clamping portion 4212, at this time, the weight to be removed is sucked out of the engine under the action of pneumatic suction force, and is transported to the outside of the engine by using the transport channel.
In an alternative, as shown in fig. 1, the pneumatic transport device 500 of the present embodiment includes a pneumatic aspirator 520 and an adjustable delivery tube for forming the transport channel 510, the pneumatic aspirator 520 being in communication with the controller 600, the pneumatic aspirator 520 being in communication with the adjustable delivery tube. Wherein, adjustable transfer pipe can be the hollow pipeline of flexible material.
In a specific implementation, the inlet of the adjustable conveying pipe is communicated with the external area of the engine, the outlet of the adjustable conveying pipe is communicated with the internal area of the engine, and the outlet of the adjustable conveying pipe is opposite to the target locking mechanism. When the target locking mechanism needs to be weighted, the controller 600 is used for controlling the adjustable conveying pipe to convey the weight 700 in the external area of the engine to the outlet of the adjustable conveying pipe, and then the controller 600 is used for controlling the pneumatic sucker 520 to provide pneumatic pressure to the inlet of the adjustable conveying pipe, so that the weight 700 enters the locking cavity of the target weight locking mechanism under the action of the pneumatic pressure. The controller 600 then continues to control the target counterweight locking mechanism to lock the counterweight 700, thereby completing the rapid balancing of the engine rotor 100.
On this basis, when the counterweight to be removed in the weighted locking mechanism needs to be removed, the controller can be used for controlling the pneumatic pressure absorber 520 to provide pneumatic suction force for the inlet of the adjustable conveying pipe, and the counterweight to be removed enters the adjustable conveying pipe under the action of the pneumatic suction force so as to transfer the counterweight to be removed to the external area of the engine, so that the rapid balancing of the engine rotor 100 can be further completed.
Exemplary, the engine rotor balancing system according to the embodiment of the present invention further includes a display device, and fig. 7 shows a schematic structural diagram of the pneumatic transfer device according to the embodiment of the present invention. As shown in fig. 7, the pneumatic transport device 500 further includes an image capture device 800 disposed at the outlet of the adjustable transport tube, and the display device is communicatively coupled to the image capture device 800. It should be understood that the outlet of the adjustable conveying pipe may also be provided with a conveying pipe cap 511 that may be opened and closed, and the image capturing device 800 may be provided on the conveying pipe cap 511 that may be opened and closed, and the image capturing device 800 may be a miniature visual probe.
In specific implementation, the image acquisition device 800 may be used to acquire a position image of the locking mechanism, then transmit the position of the locking mechanism to the display device in real time, and then adjust the relative position of the adjustable conveying pipe to be weighted and the locking mechanism according to the position image of the locking mechanism, so that an operator can remotely monitor and perform operations in real time, thereby realizing rapid assembly and safe assembly, and improving the working efficiency and reliability.
For example, as shown in FIG. 1, the engine of the present embodiment further includes a guide cavity 900, the guide cavity 900 being used to guide the adjustable transfer tube. The guiding cavity 900 is a hollow structure, and before the balance of the engine rotor is adjusted, the guiding cavity 900 is coaxially opposite to any one locking mechanism, and the adjustable conveying pipe penetrates through the cavity of the guiding cavity 900. Therefore, the guiding cavity 900 can play a role in fixing the flexible adjustable conveying pipe before adjusting the balance of the engine rotor, so that the adjustable conveying pipe is coaxially opposite to the locking mechanism, and the balance weight is more convenient to perform so as to adjust the balance of the engine rotor.
By way of example, the controller 600 may be in the form of a workstation, which may be a computer system having an interactive interface for controlling the operation of all electrical components.
The embodiment of the invention also provides an engine rotor balancing method, and fig. 8 shows a flow chart of the engine rotor balancing method of the embodiment of the invention. As shown in fig. 8, the engine rotor balancing method according to the embodiment of the invention includes:
Step 101: the controller controls the outlet of the transfer channel to be opposite to the locking cavity of the target locking mechanism based on the counterweight setting parameters. The weight setting parameters may include respective target weight positions of the weights, the target weight positions being locking cavities of a locking mechanism that is required to charge the weights.
For example, when the engine rotor needs to be weighted, the target locking mechanism does not have a balancing weight, and the controller is utilized to start the engine rotor 100 to rotate according to the setting parameters of the balancing weight, so that the fixed disc 410 and the plurality of locking mechanisms 420 can be driven to rotate simultaneously, and the target balancing weight locking mechanism is opposite to the outlet position of the transfer channel 510 and is in a coaxial state. When the counterweight to be removed in the weighted locking mechanism needs to be removed, the controller 600 may be used to control the engine rotor 100 to rotate, so as to drive the fixed disc 410 and the plurality of locking mechanisms 420 to rotate simultaneously until the counterweight to be removed is coaxially opposite to the position of the outlet of the transfer channel 510.
Step 102: when the target locking mechanism is in an unlocking state, the controller controls the pneumatic transfer device to transfer the counterweight to the locking cavity of the target locking mechanism through the transfer channel.
For example: when the target locking mechanism is in the unlocked state, the counterweight is not present in the target locking mechanism, the controller 600 can control the transfer channel 510 to transfer the counterweight 700 in the external area of the engine to the outlet of the transfer channel 510, and then the controller 600 is used for controlling the pneumatic transfer device 500 to provide pneumatic pressure to the inlet of the transfer channel 510, so that the counterweight 700 enters the locking cavity of the target counterweight locking mechanism under the action of the pneumatic pressure.
Step 103: the controller controls the target locking mechanism to lock the balancing weight.
For example: the controller 600 is used to continuously control the target counterweight locking mechanism to lock the counterweight 700, so that the rapid balancing of the engine rotor 100 can be completed.
In one implementation manner, when the counterweight to be removed in the weighted locking mechanism according to the embodiment of the invention needs to be removed, the controller is firstly used to control the weighted locking mechanism to be opened, then the controller is simultaneously used to control the pneumatic transfer device 500 to provide pneumatic suction force to the inlet of the transfer channel 510, and under the action of the pneumatic suction force, the counterweight to be removed enters the transfer channel 510 and is transferred to the external area of the engine, so that the rapid balancing of the engine rotor 100 can be further completed.
Therefore, the engine balancing system and the method provided by the embodiment of the invention can adopt the intelligent controller, the three-blade locking mechanism, the wireless actuating device, the pneumatic pressure suction device and the like under the condition that the engine main body part is not dismounted, the counterweight piece is mounted or pulled away from the counterweight surface of the engine rotor system through the pneumatic pressure suction device, and the vibration state of the engine rotor is analyzed by virtue of the airborne test equipment or the ground test bed test equipment, so that the engine rotor system is balanced, the construction period for integrally dismounting the engine in the past is greatly shortened, the maintenance and guarantee efficiency of the engine is greatly improved, and the technical risk brought by repeated dismounting of the engine is greatly reduced.
The exemplary embodiments of the present invention also provide an apparatus for balancing an engine rotor in the case where respective functional modules are divided by corresponding respective functions. The device for balancing the engine rotor comprises:
The first control module is used for controlling the outlet of the transfer channel to be opposite to the locking cavity of the target locking mechanism based on the counterweight setting parameters;
the second control module is used for controlling the pneumatic transfer device to transfer the counterweight to the locking cavity of the target locking mechanism through the transfer channel when the target locking mechanism is in an unlocking state;
and the third control module is used for controlling the target locking mechanism to lock the balancing weight.
