Title:
SELF-ALIGNING ROLLING BEARING PERFORMANCE TESTING APPARATUS AND RIGIDITY TESTING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/004911
Kind Code:
A1
Abstract:
A self-aligning rolling bearing performance testing apparatus and a rigidity testing method. A main shaft system (2) comprises a stepped main shaft (21), and a drive system (1) drives the stepped main shaft (21) to rotate. A tested bearing system (3) comprises a tested bearing (31), a bearing seat body (32), and a bearing outer race end cap (34). The bottom of the bearing seat body (32) is hinged to a vertical U-shaped member (57), the vertical U-shaped member (57) being connected to a radial loading mechanism, and the radial loading mechanism being horizontally movably connected to a self-aligning angle adjusting mechanism (6). The right end of the bearing outer race end cap (34) is hinged to a horizontal U-shaped member (52), the horizontal U-shaped member (52) being connected to an axial loading mechanism. The axial loading mechanism is vertically movably connected to the self-aligning angle adjusting mechanism (6), and a deflection angle of the tested bearing (31) is adjusted by the self-aligning angle adjusting mechanism (6). The present apparatus and method are capable of carrying out compound loading while adjusting the self-aligning angle of a tested bearing (31). Environment simulation under load conditions is relatively realistic, and the range of angle adjustment is relatively large.
