Zinc-base alloy bearing based on solid lubricating agent

Abstract

The invention discloses a zinc-base alloy bearing based on a solid lubricating agent. The zinc-base alloy bearing comprises a self-lubricating bearing outer ring, a self-lubricating bearing inner ring, self-lubricating bearing balls and self-lubricating bearing sealing covers. An outer ring ball limiting and mounting groove is formed in the inner side face of the self-lubricating bearing outer ring, and an inner ring ball limiting and mounting groove is formed in the outer side face of the self-lubricating bearing inner ring. The self-lubricating bearing outer ring and the self-lubricating bearing inner ring are each provided with multiple solid lubricating agent imbedding holes. The axes of the multiple solid lubricating agent imbedding holes are each arranged in the radial direction of the self-lubricating bearing outer ring and the self-lubricating bearing inner ring. The multiple solid lubricating agent imbedding holes are formed around the outer ring ball limiting and mounting groove and the inner ring ball limiting and mounting groove and connected with the outer ring ball limiting and mounting groove and the inner ring ball limiting and mounting groove. The zinc-base alloy bearing has the beneficial effects of being convenient to assemble, high in mechanical strength and good in lubricating effect.

Description

technical field [0001] The invention relates to the technical field of alloy casting products, in particular to a solid lubricant-based zinc-based alloy bearing. Background technique [0002] Self-lubricating bearings are a new type of bearings that replace traditional bearings that rely on oil film lubrication by processing a number of holes in an orderly arrangement and appropriate size on the bearing base, and then inserting solid lubricating materials into the holes; it has low friction coefficient and long service life. Long, easy maintenance and good wear resistance at low speed and heavy load. The solid lubricant used in self-lubricating bearings in the prior art deteriorates faster in an environment with high humidity, and its service life is severely shortened compared with that in a dry environment, that is, its water resistance is poor, which brings more troubles to actual production operations. Uncertainty. [0003] Zinc-based alloy is a high-strength wear-resi...
