Hybrid self-lubricating bearing based on ptfe fiber and its processing technology

Abstract

The invention discloses a hybrid self-lubricating bearing based on PTFE fibers and a processing technology thereof, and relates to the technical field of bearings. The PTFE fiber-based hybrid self-lubricating bearing includes a bearing body, the bearing body is embedded with a solid lubricating layer for contacting the grinding shaft, and the side surface of the bearing body is equidistantly surrounded by a number of shapes: There are strip-shaped heat dissipation grooves, and five heat dissipation capsules are arranged in a row at equal distances in a single heat dissipation groove, and the heat dissipation grooves run through the inner wall of the bearing body. The PTFE fiber-based hybrid self-lubricating bearing and its processing technology, through the design of materials in the solid lubricating layer, can form a transfer film based on the PTFE fiber mixed layer to protect the grinding shaft, effectively improving the self-lubricating performance of the bearing, and at the same time through The copper powder layer effectively improves the bearing capacity and wear resistance of the bearing, and its good thermal conductivity can transfer the heat generated during the operation of the bearing in time.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a hybrid self-lubricating bearing based on PTFE fibers and a processing technology. Background technique [0002] Self-lubricating bearings include composite material self-lubricating bearings, solid inlaid self-lubricating bearings, bimetallic material self-lubricating bearings and special material self-lubricating bearings. Different self-lubricating bearings are selected according to different uses and working conditions. Self-lubricating bearings have the characteristics of high load capacity, impact resistance, high temperature resistance, and strong self-lubricating ability. They are especially suitable for occasions where it is difficult to lubricate and form an oil film such as heavy loads, low speeds, reciprocating or swinging, and are not afraid of water flushing and other acid liquids. Erosion and erosion. During the operation, a transfer film can be formed to protec...

Problems solved by technology

[0003] When the bearing is subjected to friction, the heat generated directly affects the normal performance of the bearing itself. The poor heat dissipation effect will reduce the service life of the bearing and increase the maintenance cost. When the temperature rises rapidly and the temperature exceeds the standard, it is easy to cause The unplanned outage or load reduction operation of the unit will have a great impact on economic benefits
