SELF-LUBRICATING CERAMIC SINTERED BODY
To provide a self-lubricating ceramic sintered body having both mechanical characteristics and self-lubrication property.SOLUTION: A ball 4 of a rolling bearing 1 has a base material made of a ceramic sintered body. The base material has a three-dimensional network structure with pores facing a sliding surface, in a surface layer including the sliding surface that slides on a mating member. Lubricant is retained in the pores. The porosity of the pores in the sliding surface is 0.50% to 30%. The lubricant contains a base oil with a kinematic viscosity at 40°C of 5 mm2/s to 50 mm2/s.SELECTED DRAWING: Figure 1
【課題】機械的特性と自己潤滑性を両立した自己潤滑性セラミックス焼結体を提供する。【解決手段】転がり軸受１の玉４は、セラミックス焼結体からなる基材を有し、基材は、相手部材と摺動する摺動面を含む表層部に、摺動面に臨む空孔を有する３次元網目構造を有しており、空孔に潤滑剤が保持されており、摺動面における空孔の空孔率が０．５０％～３０％であり、潤滑剤は、４０℃における動粘度が５ｍｍ２／ｓ～５０ｍｍ２／ｓの基油を含む。【選択図】図１
