sliding member

Abstract

To provide a sliding member which has hardness that is suitable for the circumstance, to which heavy load is applied, and which is excellent in abrasion resistance property. The sliding member contains a sliding layer for slidably supporting a body to be slid, shot blasting being performed on a surface of the sliding layer, and a sliding surface formed on a surface of the sliding layer, the sliding surface having an uneven configuration with arithmetic mean roughness (Ra) of 1.0 µm through 2.5µm, 10-point average roughness (Rz) of 5.0 µm through 10.0µm, and surface hardness (Hv) of 220 through 250.

Description

technical field [0001] The present invention relates to a sliding member for supporting an object to be slid so that the object to be slid can be slid. Background technique [0002] Generally, in order to reduce friction, the sliding surface is desirably smooth. However, when the sliding surface is made smooth, although the frictional resistance can be suppressed low, the sliding surface will generate some heat, and therefore, there may be a problem caused by so-called burning. To fix (Japanese: condense). Therefore, the sliding surface is required to have an appropriate surface roughness. [0003] Conventionally, the technique of forming recesses by shot blasting the sliding surface is known, and a technique of forming an oil reservoir on the sliding surface of a sliding member by shot blasting is known (for example, refer to Patent Document 1). [0004] Patent Document 1: Japanese Patent No. 4848821 Contents of the invention [0005] The problem to be solved by the ...
