Solid lubrication thin-wall bearing with segmented self-lubricating holder

Abstract

The invention discloses a solid lubrication thin-wall bearing with a segmented self-lubricating holder. The solid lubrication thin-wall bearing comprises an outer ring and an inner ring for solid lubrication treatment, balls and the holder consisting of a plurality of arc segments. The solid lubrication thin-wall bearing has the characteristics in that the segmented holder is adopted to successfully solve the problems that a bearing with an integral holder structure operates unstably and is likely to cause whistler; a bearing channel adopts a sputtering MoS2 base composite film to serve as an initial lubricating film of the bearing, the holder is made of a self-lubricating material and can provide continuous transfer lubrication to the bearing, and thus the service life of the bearing is prolonged. According to the invention, through special design of the holder, the solid lubrication of the thin wall bearing is successfully realized. The thin-wall bearing disclosed by the invention has the advantages of being convenient to install and use, operating stably, having no whistler and having a long service life. The solid lubrication thin-wall bearing can be used for rotating support of equipment such as robots and manipulators with thin-wall bearings, and particularly equipment with special requirements on temperature range or use environment.

Description

technical field [0001] The invention belongs to the technical field of solid lubricating bearings, in particular to a solid lubricating thin-walled bearing with a segmented self-lubricating cage. Background technique [0002] Solid lubricated thin-walled bearings have the characteristics of simple installation and use, wide operating temperature range, and little pollution to the outside world. They are especially suitable for robots, manipulators, etc. Equipment swivel support. However, the existing thin-walled bearings (especially large-sized equal-section bearings) all adopt an integrated metal cage structure. After the thin-walled bearings of this structure are solid-lubricated, the cage is very weak when the bearing is running due to the poor rigidity of the cage. It is easy to deform, so that the running stability of the bearing is poor, and there is a howling sound.
