Abstract
The utility model provides a high-speed angular contact ball bearing lubrication test stand, which realizes stepless change of a high frequency motor. A transmission shaft drives an angular contact ball bearing to conduct high-speed rotation under a certain pretightening force, and an axial pretightening force is applied by adjusting weights to conduct angular contact ball bearing fatigue life test under various rotation speeds and loads. The device overcomes the shortcomings in the prior angular contact ball bearing fatigue life test device, including complex structure, expensive price, complex operation, large noise, and on the like; realizes zero drive and lever-loading; and has the advantages of high speed, excellent performance, reliable test result, simple structure and low cost.

A kind of simple type angular contact ball bearing lubrication test platform, this testing table comprises drive unit, tested bearing assembly, charger and a vertical test-bed:
Drive unit is located at the top of test-bed, and this drive unit is made up of frequency converter and high-frequency electric machines, is used for hypervelocity and drives tested angular contact ball bearing, and tested Bearing Installation is on accurate main shaft, and the mounting hole by accurate grinding is connected with high-frequency electric machines;
Tested bearing assembly is positioned over the below of test-bed, this assembly comprises loading cover, bearing seat, back-up ring and fixed part, loading is sheathed in the fixed part on the test-bed base, be provided with stop means between the lateral wall of loading cover and the fixed part, make that loading cover can slide up and down in spacing scope, bearing seat is located at and is loaded in the cover, and the bottom surface in the bearing seat is provided with back-up ring;
Charger is a simple and easy loading lever, and the fulcrum that loads lever is arranged on the base of test-bed, and an end that loads lever offsets with the bottom that loads cover, the other end loads by counterweight customized.
The course of work of angular contact ball bearing lubrication test platform of the present invention is: realize the stepless change of high-frequency electric machines hypervelocity by frequency converter, drive accurate main shaft and realize the angular contact ball bearing high speed rotating, adopt counterweight to regulate and load axial pre tightening force, carry out the angular contact ball bearing fatigue life test under various rotating speeds, the load working condition.
Beneficial effect: the invention provides a kind of simple type angular contact ball bearing lubrication test platform, break through at present existing test unit complex structure, cost an arm and a leg, complex operation, shortcomings such as noise is bigger, can simulate angular contact ball bearing fatigue life test under the various operating modes easily, obtain good test effect.Its advantage is:
1) among the present invention, angular contact ball bearing by accurate main shaft directly and high-frequency electric machines be rigidly connected, high-frequency electric machines directly drives angular contact ball bearing, guaranteed the right alignment of motor shaft and bearing precision main shaft, realize " zero transmission ", greatly reduced the influence of the shock load that produces in the process of the test and noise torture test;
2) test unit of the present invention adopts the vertical structure layout, makes to become a reality by the lever loading, compares with traditional hydrostatic transmission load maintainer, and lever loaded load of the present invention is adjustable, the amplitude of accommodation big, simple structure, easy to operate, with low cost;
3) drive high-frequency electric machines by the medium-high frequency frequency converter and drive tested bearing, realize the stepless change of tested bearing, " zero transmission " technology has realized the even running of 90,000 rev/mins of working speeds in addition;
4) simple and easy vertical structure device of the present invention, rolling bearing is open layout, can make things convenient for the installation and removal of ball bearing.
