Abstract

The utility model provides an angular contact ball bearing life test axial loading device, which comprises a core shaft, a locking screw arranged at one end of the core shaft and an axial loading block, a shaft end gland is clamped between the core shaft and the locking screw, one end of the shaft end gland is arranged corresponding to an inner ring of a test bearing, a loading ball is arranged on the locking screw in a pressing manner, and the axial loading block is arranged on the loading ball. The loading ball is clamped between the locking screw and the axial loading block, and the axial loading block carries out service life test axial loading on the inner ring of the test bearing through the loading ball and the shaft end gland under the axial load of the loading head of hydraulic loading or electric cylinder loading. The utility model provides a tool capable of directly carrying out axial loading on the service life test of the inner ring of the angular contact ball bearing, so as to meet the service life verification of the tested bearing under special working conditions, and has the characteristics of simple structure and convenience in operation.
