Description
Technical field
The invention belongs to a kind of bearing performance testing machine, particularly a kind of bearing outside diameter is the super-huge turntable bearing performance aircraft of φ 1600-φ 3500mm.
Background technology
Adjustment along with China's energy structure, wind-power electricity generation occupies more and more important share as a kind of clean energy resource, huge the increasing in wind energy bearing market as large-scale turntable bearing, but because domestic production producer lacks corresponding test condition, can't do further improvement and raising to bearing performance, bigger with the external product gap.Along with the aggravation of wind energy market competition, reliability of products is required all the more strictness, main engine plants have proposed more and more stricter requirement to wind energy Production of bearing merchant, do not have research technique, will be difficult to obtain user's the approval and the market access.Even we have solved problems such as product design, process equipment, processing technology measurement, the user also is difficult to accept not pass through the product of verification experimental verification.And product in case lost efficacy in the user uses will give manufacturer in reputation with bring about great losses economically, and this risk is that any Production of bearing factory is difficult to accept.For the test of extra large size bearing, because the external main manufacturing enterprise of the importance of bearing all quite payes attention to, in order to guarantee reliability of products, the huge fund of all not stinting is carried out simulation test by the whole bag of tricks to its product.By test well designed, improvement technology, make its product reach quite high technical merit and reliability.But because such testing machine belongs to the crucial specialized equipment of super-huge turntable bearing development, external bearing producer is to this testing machine blockade on new techniques, and domestic production producer lacks corresponding test condition.Because especially big property bearing tester complex structure, the investment bigger, domestic also do not have a Related product, has only some producers to make some brief test devices, owing to can not simulate the bearing operating mode, the detection of turning quality can only be done, checking effect can't be played product.
Summary of the invention
The purpose of this invention is to provide a kind of super-huge turntable bearing performance aircraft, can measure the starting friction moment of tested bearing after loading radial pressure and the instant moment of friction value during rotation status by the hydraulic loaded mode, and the stationarity of the running of observation bearing in loading procedure.
The present invention mainly is made of operation power device, charger, fulcrum arrangement and hydraulic means,
Test bearing encloses surely with work top and connects with high-strength bolt, moving-coil links to each other with the operation power device by gear drive, and be connected with loading arm device front end transition disc, oil cylinder by the charger end loads a certain amount of upsetting moment to the test bearing that rotates, thereby test bearing is done performance test.Fulcrum arrangement is mainly used in the installation and removal of test bearing, during the bearing load test, needs fulcrum arrangement is stepped back, and makes loading arm be in cantilever position.
Described operation power device is to comprise motor, speed reduction unit, shaft coupling, torque sensor, splined shaft, bevel gear, pinion wheel.Motor, reductor are connected with splined shaft, between speed reduction unit and splined shaft torque sensor are housed, and directly measure and export the actual torque value.The test bearing rotating speed can be realized stepless speed regulation.Be connected with positive coupling between reductor and the torque sensor, by splined shaft power is passed to one group of one-level bevel gear with axes at right angles, thereby drive pinion wheel and drive the internal tooth or the external tooth engaged transmission of tested bearing again by pinion wheel, thereby measure the moment values of bearing under various load.
Described charger comprises transition disc, loading arm, self-aligning roller bearing and load cylinder.After test bearing moving-coil, transition disc and loading arm connect, test bearing is enclosed surely with high-strength bolt and work top binding, regulate the steel wire wheel axle of worktable side, external tooth or internal tooth on the test bearing are meshed with pinion wheel.The right-hand member of loading arm then links to each other with load cylinder with a cover self-aligning roller bearing, by oil cylinder maximum to a certain amount of radial force is added on the loading arm, thus the disturbing moment that simulation applies.Adopt self-aligning roller bearing to make loading arm under the situation of pressurizing and deformation, can adjust automatically.The amount of overcoming that acts on the test bearing when lengthening makes applied voltage test as far as possible owing to loading arm reduces, and reduces the influence of the moment of friction of test bearing generation to test findings as far as possible.
Described fulcrum arrangement comprises track, motor, gear, tooth bar, leading screw, nut seat, adjustment bolt, front and back supporting, car frame.The front and back supporting is contained in respectively in the car frame, and two dollies are fixed together with connecting link, by gear, tooth bar loading arm are transplanted on the installation site along track by motor.In the supporting of front and back retainer and short columnar roller are housed, conveniently to tighten up the bolt that test bearing is connected with worktable.When transferring the left and right sides,, pull leading screw, drive whole supporting move left and right with the leading screw in the stubborn dolly of spanner left side; When transferring up and down, then adjust with the adjustment bolt under the supporting; Thereby can reach dolly drive loading arm top to bottom, left and right, front and rear moves.
Described hydraulic loaded control device comprises Variable plunger pump, motor, tensimeter, solenoid valve, load cylinder, proportional pressure control valve, oil suction filtrator, hydraulic reservoir, electricity liquid ratio relief valve.Hydraulic loading system is the mesohigh system, is used for test bearing is loaded.By electricity liquid ratio relief valve control system pressure, can adjust the size that loads load automatically by electrical control.
Through test bearing is carried out simulation test, test its starting friction moment and current value unloaded and when loading 25%, 50%, 75%, 100% radial force respectively, to disintegrate behind the loaded, every index of test bearing reaches customer requirements.Show that by a large amount of test figures the startup of bearing and spin friction moment become certain linear with the upsetting moment of loading ability of bearing, the design that can thus be bearing provides certain data with manufacturing.But the following performance of the present invention's test bearing:
1) starting friction moment and the pivoting friction torque of test bearing under unloaded and various loaded-up conditions changes; 2) test bearing workplace contact condition and rubbing wear state; 3) test bearing sealing and leakage fat performance, rubbing wear and sealing life; 4) the smoothness of operation test of test bearing under various loaded-up conditions; 5) test bearing permanance; 6) test meets other dynamic properties of device specifications; 7) can generate drafting electric current-moment of friction curve, moment of friction-time curve automatically according to test parameters.
In sum, the present invention can simulate all kinds of turntable bearing operating modes substantially, and directly measures and real time record output test data by industrial computer.After the off-test, bearing removal is got off, check the performance behind its bearing load.To verify by test whether the combination property of this class bearing is up to standard, improves product reliability greatly, and can improve product design and processing technology, further improve the product integral level by test findings.Succeeding in developing of super-huge turntable bearing performance aircraft makes us can significantly improve reliability of products, for further improving product design, improving technology important experimental data is provided.Simultaneously also will shorten China's super-huge turntable bearing test level and external gap greatly, thereby improve the product level, promote the market share of home products.
