Title: Rolling bearing
Inventor: YAMADA HIROSHI
IPC: F16C33/44
Filed: 1997-07-15
Abstract: PROBLEM TO BE SOLVED: To ensure excellent lubricating ability so as to improve durability by forming a hard layer, formed of TiN, TiCN, or the like, on the friction face or contact face of a bearing ring or a rolling element, and forming a solid lubricating layer, formed of an MoS2 film, on the surface of the hard layer. SOLUTION: A rolling bearing has a bearing ring, rolling elements and a cage as components. A hard layer is formed on the rolling friction face or sliding contact face of the bearing ring or rolling element, and a solid lubricating layer formed of an MoS2 film is formed on the surface of the hard layer. As the hard layer, a film of TiN, TiCN, CrN, Cr2 N, or the like superior in surface pressure withstanding strength to a TiC film, and a chrome metal film or chrome plated film can be used. Not the independent layer of each film but multilayer structure can also be formed. As a method of forming the hard film, an ion plating method is effective from the viewpoint of a forming condition and workability. The hard layer and solid lubricating layer can be formed on the rolling friction face or sliding contact face of the cage, but molding out of self-lubricating resin is also possible. With this constitution, durability is considerably improved under high vacuum and high load.
