Abstract

The invention provides an impact test table based on the axial loading of a wind power high-speed shaft bearing. The impact test table comprises a base table, a driving motor, a fly wheel, a clutch, a rotating main shaft, a main test bearing, an axial loading device and a magnetic power brake, wherein the driving motor is arranged at one end of the base table, an output shaft of the driving motor is connected with one end of a center shaft of the fly wheel, the clutch is arranged on the base table through a support frame, the other end of the center shaft of the fly wheel is connected with the input end of the clutch, the output end of the clutch is connected with one end of the rotating main shaft, the magnetic power brake is arranged at the other end of the base table, the other end of the rotating main shaft is connected with a brake shaft of the magnetic powder brake, and the main test bearing is arranged on the rotating main shaft and is fixedly arranged on the base table. The invention provides the impact test table based on the axial loading of the wind power high-speed shaft bearing. The impact test table has the advantages that the rotating impact load can be effectively simulated, the axial loading of the bearing is convenient and fast, and the cost is reduced.

Description

technical field [0001] The invention relates to an impact test bench for axial loading of bearings, in particular to an impact test bench based on axial loading of wind power high-speed shaft bearings. Background technique [0002] The main function of the wind power gearbox is to transmit the power generated by the wind wheel under the action of the wind to the generator and make it obtain a corresponding speed. The mechanism of the wind power gearbox adopts two-stage planetary transmission plus one-stage parallel shaft transmission. Usually, the two-stage planetary transmission structure of the low-speed stage and the middle stage is relatively stable during use, but as the end of the wind power gearbox transmission, the high-speed shaft bearing Subject to large dynamic axial force, and as the intermediate connection between wind power gearbox and generator, high-speed shaft bearings often need to bear large impact steering loads at the beginning and end of power generatio...
