Title:
BEARING MEMBER, HOUSING AND BEARING DEVICE USING THESE
Document Type and Number:
Japanese Patent JP2020079605
Kind Code:
A
Abstract:
To provide a bearing member capable of reducing change in the outer diameter of the bearing member in operation to reduce fretting damage, a housing, and a bearing device using the bearing member and the housing.SOLUTION: A bearing member comprises an outer peripheral surface that is formed in an integral cylindrical shape or an arc cylindrical shape divided in a circumferential direction, assembled into a housing on an outer peripheral side, and provided on the side opposite to an inner peripheral surface of the housing. A maximum height Rz (μm) of the surface roughness of the outer peripheral surface is 2.00 μm≤Rz≤4.00 μm, and a value of a ratio between a protruding peak average height Rpk (μm) and a load length ratio Mr1 (%), which is a parameter in a load curve of the surface roughness, is 0.010≤Rpk/Mr1≤0.100.SELECTED DRAWING: Figure 1
