Mechanism, device and method for monitoring wear amount of joint bearing self-lubricating liner

Abstract

The invention relates to the technical field of bearing health monitoring, in particular to a mechanism, device and method for monitoring the wear amount of the self-lubricating liner of a joint bearing, including a fixing frame for placing the spherical bearing, and the fixing frame is symmetrically arranged in the horizontal direction. Two rotatable cantilever supports; the two ends of the cantilever supports are respectively fixedly connected to the transmission racks on the two ends of the sleeve rod, the transmission racks are matched with the gears, and the gears are connected to the transmission shaft Connection; the middle part of the sleeve rod is provided with a guide groove for passing through and fixing the motion shaft of the joint bearing. The mechanism provided by the invention can perform differential measurement on the joint bearing to eliminate various errors, obtain accurate wear amount data, and can realize non-contact online detection of the wear amount of the joint bearing self-lubricating liner in the working state, which is convenient for us at any time Monitoring the wear amount of the joint bearing and preventing the damage of the joint bearing has a good application prospect.

Description

technical field [0001] The invention relates to the technical field of bearing health monitoring, in particular to a mechanism, device and method for monitoring the wear amount of a self-lubricating liner of a joint bearing. Background technique [0002] The spherical plain bearing is a special sliding bearing composed of an outer ring with an inner spherical surface and an inner ring with an outer spherical surface. A layer of self-lubricating liner is embedded or bonded between the inner and outer rings, and the friction between the surface of the liner layer and the steel of the inner ring is used to replace the direct steel-to-steel friction of the inner and outer rings, which completely breaks through the limitation of relying on grease lubrication It achieves oil-free lubrication and is widely used in major equipment such as aerospace, engineering machinery, and water conservancy machinery. [0003] The main failure mode of self-lubricating spherical plain bearings is...
