Composite slide bearing

摘要

A high-precision slide bearing includes a substrate of sintered metal and a synthetic resin layer. The bearing can be used for rotary shafts in compressors of room air-conditioners or in transmissions of motor vehicles and construction machines to support relatively large radial and axial loads. The resin layer is integrally superposed on the radially inner surface of the sintered metal substrate of the slide bearing, which is a cylindrical member. The resin layer is made of a resin composition of an aromatic polyetherketone resin containing a fibrous filler. The fibrous filler is made up of fibers dispersed in the resin layer and oriented such that their length directions intersect the rotational direction of the bearing at angles of 45 to 90 degrees. The resin layer has a thickness of 0.1 to 0.7 mm.

1. A composite slide bearing comprising:
a substrate made of a sintered metal; and a resin layer fixedly superposed on the substrate; wherein the resin layer is an injection-molded resin layer having a resin composition comprising an aromatic polyetherketone resin and a fibrous filler dispersed in the aromatic polyetherketone resin and is finished to a required resin thickness by machining after injection molding, wherein the fibrous filler comprises fibers which are oriented such that a length direction of each of the fibers intersects a rotational direction of the bearing at an angle of 45 to 90 degrees, and wherein the resin layer has a thickness of 0.1 to 0.7 mm.
