Abstract

The invention belongs to the technical field of bearing stiffness detection, and provides a detection device and method for radial stiffness of a bearing ring with a mounting flange. The detection device for the radial stiffness of the bearing ring with the mounting flange comprises a base (1), a vertical plate (3) fixed on the base, a measuring meter frame (6), a measuring meter (7) and a load block; a positioning disc (5) is fixed on the vertical plate (3), and the positioning disc (5) is of an annular structure of which the center is provided with stepped through holes; the measuring meter frame (6) is mounted on the measuring plane on the upper portion of the vertical plate (3), and the bearing ring (9) with the mounting flange is installed on the vertical plate (3) through the positioning disc (5); the detection device further comprises a loading assembly (8) which is of an annular structure formed by connecting an upper semi-ring (13) and a lower semi-ring (14), and the load block (11) is hung on the lower semi-ring (14) of the loading assembly. By means of the detection device and method for the radial stiffness of the bearing ring with the mounting flange, the limitation problem of the detection device for the radial stiffness of the elastic supporting bearing ring with the mounting flange is solved.

Description

technical field [0001] The invention belongs to the technical field of bearing stiffness detection, and mainly relates to a detection device and method for the radial stiffness of a bearing ring with a mounting edge, which is suitable for precise measurement of the radial stiffness of a bearing ring with an outer mounting edge elastically supported. Background technique [0002] Elastic support bearings are widely used in key parts of high-end mechanical rotary devices such as aviation and aerospace. The radial stiffness index of elastic support bearing rings is an important characteristic of elastic support bearings. The detection of radial stiffness involves aerospace and aviation machinery hosts. safety and reliability. The existing radial stiffness detection method of the elastic support ring is usually to directly fix and install the tested bearing ring by bolts, and directly add a concentrated load to the free end of the elastic support bearing ring by using a lanyard,...
