Abstract

The invention discloses copper-based rolling bearing lubricating grease and a rolling bearing abrasion self-repair method. The lubricating grease comprises base lubricating grease and submicron copper powder uniformly dispersed in the base lubricating grease, wherein the diameter of the submicron copper powder is 0.3-10 microns, and the mass fraction of the submicron copper powder in the copper-based rolling bearing lubricating grease is 0.5-5%; and in the working process of a rolling bearing, the friction abrasion surface of the rolling bearing is lubricated by adopting the copper-based rolling bearing lubricating grease, and the abraded surface is filled with the submicron copper powder in the copper-based rolling bearing lubricating grease to realize automatic repair of the abraded part of the rolling bearing. The submicron copper powder is just matched with the roughness of 0.508-25.4mu m of a metal machining surface, the submicron copper powder which is spherical or approximately spherical can change the sliding friction mode of existing lubricating grease into a rolling friction mode, and the submicron copper powder used as a soft isolating layer can play a good role in spacing and protecting a friction surface, so that the frictional resistance and the abrasion are reduced.

Description

technical field [0001] The invention relates to the technical field of bearing lubrication, in particular to a copper-based rolling bearing lubricating grease and a self-repairing method for rolling bearing wear. Background technique [0002] When the rolling bearing is in operation, the balls of the rolling bearing and the inner and outer rings of the bearing make high-speed relative motion under a small gap and a large load-bearing pressure. But it is uneven. If these surfaces are not lubricated, intense friction will occur between them. The dry friction between the metal surfaces not only increases the power consumption of the rolling bearing and accelerates the wear of the working surface of the parts, but also may burn the working surface of the parts due to the heat generated by the friction, making the rolling bearing unable to operate. [0003] The role of grease is to form an oil film between the friction surfaces, thereby reducing frictional resistance, reducing ...
