SLIDE BEARING STRUCTURE OF SHAFT MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a slide bearing structure of a shaft member by which sliding resistance during low temperature can be quickly reduced and cooling operation during high temperature by lubricating oil is not hindered.

SOLUTION: In sliding bearing structure of the shaft member in which the lubricating oil is fed between sliding faces of the shaft member 10 and a bearing member 12 which can relatively rotate, annular grooves 16 are formed both ends of an inner peripheral surface of the bearing member 12, and annular members 18 separated from the shaft member and the bearing member are arranged in positions corresponding to the annular grooves 16. The annular members 18 are formed of a material having such a coefficient of thermal expansion that the inner diameter of the annular members becomes smaller than that of the bearing member 12 during low temperature and becomes not less than that of the bearing member during high temperature.
