Self-lubricating bearing, manufacturing method thereof and application thereof

The invention belongs to the field of self-lubricating bearings, and discloses a self-lubricating bearing, a manufacturing method thereof and application thereof. The self-lubricating bearing comprises a bearing inner ring and a bearing outer ring, wherein the bearing inner ring is arranged in the bearing outer ring in a sleeving mode; the bearing inner ring is in sliding connection to the bearingouter ring; each of the bearing inner ring and the bearing outer ring is composed of a metal base material and a wear-resisting lubricating layer coated outside the metal base material; each wear-resisting lubricating layer comprises TiWC2, Ti2CS, TiCr-Cr3C2 as well as CrS and WS2; the bearing inner ring and the bearing outer ring are of ring-shaped structures; a gap between the bearing inner ring and the bearing outer ring is 0.1mm-2mm; and lubricating through holes are uniformly formed in the surface of the bearing inner ring. The self-lubricating bearing is good in self-lubricating effect,is good in wear-resisting
