Device for detecting axial clearance and radial clearance of joint bearing

Abstract

The invention provides a device for detecting an axial clearance and a radial clearance of a joint bearing. The device consists of dynamometers, a clearance measuring meter, a loading slipway, an unloading slipway, a bearing clamp and a rack. The joint bearing is mounted between the two dynamometers through the bearing clamp; the dynamometers are mounted on the loading / unloading slipway; the loading / unloading slipway is mounted on the rack; and the clearance measuring meter is fixed on the rack. The device can detect the axial clearance and the radial clearance of the joint bearing, and the axial clearance and the radial clearance of the joint bearing can be measured by exchanging different bearing clamps. By the invention, the loading and unloading of different loads in the measurement can be realized.

Description

technical field [0001] The invention relates to a detection device for measuring the axial clearance and radial clearance of a spherical plain bearing, especially a device which integrates the axial clearance detection and radial clearance detection of a spherical plain bearing into one device, and A joint bearing axial clearance and radial clearance detection device capable of realizing loading and unloading of different load values ​​during measurement. Background technique [0002] Spherical joint bearing is a kind of sliding bearing with special structure, which is mainly composed of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface. Joint bearings are widely used in the connection of swing components of aerospace vehicles. Axial clearance and radial clearance are the main technical indicators of joint bearings. The clearance of spherical plain bearing is not only the main parameter to check whether the spherical plain bear...
