Sliding device

Abstract

A sliding device (1) is composed of a swash plate (3) that rotates in conjunction with a rotation shaft (2), and a plurality of hemispherical shoes (4) that slide on the swash plate (3). The hemispherical boots (4) are made of iron materials, and the swash plate (3) is made of high-strength brass. On the sliding surface (4A) of the shoe (4), a plurality of minute annular bulges (7') are formed by laser quenching, and at the same time, lubricating oil passages (10') composed of mesh-like recesses are formed. It is possible to provide a sliding device (1) having excellent seizing resistance compared with the prior art.

Description

technical field [0001] The present invention relates to a sliding device, and more particularly to a sliding device suitable as, for example, a swash plate and a shoe in a swash plate type compressor. Background technique [0002] Conventionally, compressors including a swash plate rotatably provided and a shoe having a sliding surface sliding on the swash plate are known as swash plate compressors (for example, Patent Document 1 and Patent Document 2). [0003] Patent Document 1: Japanese Patent Application Laid-Open No. 10-153169 [0004] Patent Document 2: Japanese Patent Laid-Open No. 2002-317757 [0005] However, the above-mentioned conventional swash plate compressors are recently used under conditions of high speed and high load, and are used under conditions with a small amount of lubricating oil. Thus, recently, the operating conditions of the swash plate type compressor have become increasingly severe, so there arises a problem that the wear of the swash plate or...

Problems solved by technology

Thus, recently, the operating conditions of the swash plate type compressor have become increasingly severe, so there arises a problem that the wear of the swash plate or shoes is severe, and their sintering easily occurs.

[0006] Moreover, in order to improve the sliding characteristics of the boots from the prior art, the sliding surface of the boots is subjected to surface treatment or modified treatment, but due to such a treatment, there is a disadvantage that the manufacturing cost of the boots increases
