Problems solved by technology

This kind of bearing testing machine only applies radial load to the tested bearing in the process of testing the tested bearing, but does not apply axial load to the tested bearing
During the working process of the bearing, its force situation is relatively complicated, and the bearing will be subjected to both radial force and axial force. If the bearing (especially some special bearings) is tested, only Radial loads or just axial loads do not reflect the actual service life of the tested bearings very well

Embodiment Construction

[0020] As shown in the figure, the structure of the bearing testing machine of the present invention includes a frame 1, a radial load device 2 and an axial load device arranged on the frame 1. A mounting base 6 is provided on the frame 1, and the mounting base 6 is used for mounting the tested bearing 5. The frame 1 is also provided with a rotating shaft 3, the rotating shaft 3 is a cantilever structure, and the free end of the rotating shaft 3 extends into the position of the mounting seat 6. The radial load device 2 is arranged below the rotating shaft 3 , and the radial load device 2 and the rotating shaft 3 are connected through a transmission belt 11 . A mounting hole with a stepped surface is provided on the mounting base 6. After the tested bearing 5 is installed in the mounting hole, a bowl-shaped pressure plate is provided on the mounting base 6 outside the tested bearing 5, and the bowl-shaped pressure plate passes through the The fastening bolts are fixed on the m...

Abstract

The invention discloses a bearing tester solving the problems that a traditional bearing tester cannot favorably simulate the practical conditions of a bearing, and the measured data has poor accuracy. The invention adopts the technical scheme that the bearing tester comprises a stand, a mounting seat arranged on the stand and a rotating shaft penetrating into the mounting seat and a radial loading device arranged on the stand, wherein the radial loading device and the rotating shaft are connected through a conveyer belt. The bearing tester is characterized in that the stand is provided with the axial loading device which comprises a punch and a power mechanism, and the end part of the punch applies an axial load on the rotating shaft under the driving of the power mechanism.

Description

technical field [0001] The invention belongs to the technical field of bearings, in particular to a bearing testing machine for testing the service life of bearings. Background technique [0002] Bearing is a standardized and highly specialized product with complex working conditions. Sometimes even if the shape is the same or even the precision is high, it may not meet the actual requirements. Some special testing and testing equipment must be used to simulate the working conditions. Tests can be conducted to assess whether it meets the required technical requirements. At present, some testing and testing equipment are basically general-purpose testing equipment such as life reliability strengthening tests, and many special-purpose testing equipments are still blank. [0003] A Chinese invention patent application (200910307666.0) discloses a large-scale bearing testing machine, which is composed of a test unit, a loading unit, a drive unit, a control unit, a hydraulic pow...
