[0034] See attached Figure 1 As shown, an embodiment of the utility model is a high-load bearing ring testing device, including a base 1, a test frame 2 fixedly connected to the top of the base 1, a bearing ring fixing mechanism 3 for fixing and rotating the high-load bearing ring to be tested, and a bearing ring testing mechanism 4 for high-load bearing ring testing.

[0036] See attached Figure 5 As shown, the bearing ring testing mechanism 4 includes an electric telescopic rod 401 fixedly connected to the test frame 2 , and a test head 402 is installed at the bottom of the electric telescopic rod 401 .

[0037] See attached Figure 3-4 As shown, the fixing assembly 302 includes a fixing structure 3021 for fixing the high-load bearing ring to be tested, and a limiting assembly 3022 for limiting the high-load bearing ring to be tested is installed on the side of the fixing structure 3021.

[0038] The fixed structure 3021 includes a hollow mounting column 30211 fixedly connected to the output shaft of the rotating motor 301 , and a plurality of clamping assemblies 30212 arranged at equal distances are mounted on the hollow mounting column 30211 .

[0039] The clamping assembly 30212 includes an electric cylinder 30213 fixedly connected to the inner wall of the hollow mounting column 30211 , and an arc-shaped clamping plate 30214 is fixedly connected to the output end of the electric cylinder 30213 .

Therefore, under the interaction between the first limit baffle 30221 and the second limit baffle 30222, the bearing ring can be conveniently and firmly clamped, thereby avoiding the deflection during the bearing ring test. Then, the test head 402 is driven downward by the electric telescopic rod 401, and the test head 402 is made to contact the outer wall of the clamped bearing ring to be tested, and then the rotating motor 301 is turned on, so that the wear resistance of the bearing ring can be detected.
