ROLLING SUPPORT DEVICE, ROLLING BODY AND ITS MANUFACTURING METHOD
PROBLEM TO BE SOLVED: To provide a rolling support device which is excellent in an electric corrosion prevention effect, adapted to a use requiring low torque, and excellent in a sound characteristic and durability.SOLUTION: A rolling support device comprises at least a first member and a second member having raceway faces which are oppositely arranged, and a plurality of ceramic rolling bodies which are rollingly arranged between the raceway faces of both of the members, and manufactured by granulating raw material powder with alumina-zirconia as a main component, producing granulating powder whose grain diameter is not larger than 50 μm, and applying primary calcination and HIP treatment to a molded body after molding the granulation powder. Either of the first member and the second member relatively moves with respect to the other by the roll of the rolling bodies.
【課題】電食防止効果に優れ、低トルク化を図ることが要求される用途に適し、音響特性や耐久性に優れる転がり支持装置を提供することを目的とする。【解決手段】互いに対向配置された軌道面を備えた第１部材および第２部材と、両部材の軌道面間に転動自在に配置され、アルミナ−ジルコニアを主成分とする原料粉末の造粒を行い、粒径が５０μｍ以下の造粒粉を作製し、前記造粒粉の成形後の成形体に一次焼成及びＨＩＰ処理を施すことで作製した複数のセラミックス転動体と、を少なくとも備え，転動体が転動することにより第１部材および第２部材の一方が他方に対して相対移動する転がり支持装置。【選択図】図１
