Embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail:
As shown in Figure 1, dead electricity type joint rotating electromagnetic lock device comprises main shaft 1 and is fixed on bearing support 3 by two bearings 2 and jump ring 22, and bearing support 3 has five counterbores being connected and fixed for electromagnetic lock and supporting element, main shaft 1 is for transmitting to be locked rotary torsion.Friction disc pack 5 is fixed on main shaft 1 by an elastic spring 17, and control its axial position by main shaft 1 locating face, it is axially that elastic periphery is to the feature in rigidity that elastic spring 17 has, friction disk normally movement vertically can be ensured, ensure again the transmission circumferentially of extraneous torsion, determine friction plate assembly 4 fixing with bearing support 3 machinery, it is fixing that movable friction plate assembly 6 and bearing support 3 adopt elasticity of spring leaf to suspend, Assurance component axial elasticity and circumferential rigidity, its axial position is by abutment sleeve 12 and abutment sleeve 14 controlling and adjustment, the arranged outside of movable friction plate assembly 6 has magnetic groove 7, the side of magnetic groove 7 has through hole, bolt 11 is through through hole, magnetic groove 7 movable friction plate assembly 6 is fixed on bearing support 3 by abutment sleeve 12 and abutment sleeve 14, magnetic groove 7 is hollow structure, middle space segment is provided with spring 10, the outside of spring 10 is fixed by plug, when electromagnetic lock normally works, magnetic groove 7 circumference distribution 6 balance springs are coordinated to compress movable friction plate assembly 6 by spring 10, friction disc pack 5 and determine friction plate assembly 4, the face that contacts with each other is made to produce the extraneous torque force of frictional force counteracting main shaft 1 transmission.Movable friction plate assembly 6 substrate material adopts No. 10 steel, and coil winding 15 coordinates a certain proportion of curing agent to be fixed on magnetic groove 7 by resin glue 16.Be fixed with elastic buffer post 8 outside coil winding 15, elastic buffer post 8, for cushioning movable friction plate assembly 6 and the collision of magnetic groove 7, can not produce obvious Strike note in working procedure.Stop screw 18 is arranged on main shaft 1, and stop screw 20 is arranged on the bearing support 3 relative with main shaft 3, and they can be used in particular cases limiting main shaft and rotate continuously in the same direction.
Working procedure:
After coil winding 15 is energized, No. 10 steel matter magnetic grooves 7 and movable friction plate assembly 6 are magnetized instantaneously and attract each other, and offset spring 10 elastic force vertically, movable friction plate assembly 6, friction disc pack 5 and determine friction plate assembly 4 and mutually unclamp, namely main shaft 1 lock state is removed.After coil winding 15 power-off, No. 10 steel structure demagnetizations and magnetic groove 7 mutual attractive force disappear, and spring 10 compresses movable friction plate assembly 6 vertically, friction disc pack 5 and determine friction plate assembly 4, and main shaft 1 is in the lock state under the effect of friction torque.
Mode of execution:
As shown in Figure 2: Electromalgnetic locking mechanism b, by main shaft 1 tapped hole vertical columns a, is fixed on cantilever c by bearing support 3 five counter sinks.During Electromalgnetic locking mechanism b no electric circuit, being in the lock state, there is certain rotation torque relative to principal post a in cantilever c, can not freely rotate, and when extraneous torsion exceedes Electromalgnetic locking mechanism b design torque, can realize band resistance and rotate.When Electromalgnetic locking mechanism b to be exchanged by switch connection 24V or direct current time, according to above-mentioned working procedure, Electromalgnetic locking mechanism b is in released state, and now the relative principal post a of cantilever c does not exist rotation torque, can rotate freely by non-resistance.Under released state, when the rotation of cantilever c needs to be limited to one week range of motion, stop screw 20 can be screwed in bearing support 3 and be realized by stop screw 18 backstop.
Dead electricity type joint rotating electromagnetic lock device is connected with associated structural component by main shaft 1 tapped hole and bearing support 3 flange hole and is fixed.When two, device lead-in wire exchanges with 24V or DC power supply switch disconnects, device is in the lock state, and the realization of lock state, therefore can as required when extraneous moment of torsion be greater than adjusted value or design load based on tribology principle, and resistive torque rotation is with in realization.When two lead-in wires exchange with 24V or DC power supply switch connects, device is in released state, and the structural member be now connected with main shaft 1 and the structural member be connected with bearing support 3 can rotate relatively freely.Main shaft 1 realizes axial restraint with bearing support 3 by bearing 2 and jump ring 22, and stop screw 18 and 20 can be used in particular cases limiting main shaft and rotates continuously in the same direction.Friction disc pack 5 is mechanically fastened at main shaft 1 by an elastic spring and controls its axial position by main shaft 1 locating face, this reed is through particular design, have is axially that elastic periphery is to the feature in rigidity, namely this design ensure that friction disk normally movement vertically, in turn ensure that the transmission circumferentially of extraneous torsion.Determine friction plate assembly 4 fixing with bearing support 3 machinery, it is fixing that movable friction plate assembly 6 and bearing support 3 adopt elasticity of spring leaf to suspend, and Assurance component axial elasticity and circumferential rigidity, its axial position is by abutment sleeve 12 and 14 controlling and adjustment.When device normally works, magnetic groove 7 circumference distribution 6 balance springs are coordinated to compress movable friction plate assemblies 6 by spring 10, friction disc pack 5 and determine friction plate assembly 4, the face that contacts with each other is produced extraneous torque force that frictional force offsets main shaft 1 transmission.The elastic force of spring 10 is adjusted by hexagon by trim ring 9, can the design torque of regulating device as required.Magnetic groove 7 and movable friction plate assembly 6 substrate material adopt No. 10 steel, after coil winding 15 is energized, both are magnetized instantaneously and attract each other, and offset spring 10 elastic force vertically, movable friction plate assembly 6, friction disc pack 5 and determine friction plate assembly 4 and mutually unclamp, namely main shaft 1 lock state is removed.Elastic buffer post 8 collision of buffering movable friction plate assembly 6 with magnetic groove 7, can not produce obvious Strike note in working procedure.
