Title: Bearing structure for universal joint
Inventor: OZEKI MITSUMASA
IPC: F16C35/067
Filed: 1988-10-07
Abstract: PURPOSE:To effectively prevent the relative rotation between a yoke and the bearing case of a joint cross by forming the minor diameter face of the bearing hole of a yoke and the major diameter face of the bearing case of the bearing of a joint cross to a cylindrical face in configuration which corresponds to each other, providing for this cylindrical face a distorted circular section, and fitting and fixing the bearing case to the bearing hole. CONSTITUTION:The minor diameter face of the bearing hole 6 of a yoke 4 and the major diameter face of the bearing case 8 of the bearing 7 of a joint cross 5 are formed in a cylindrical face which corresponds to each other. This cylindrical face has a distorted circular section in which a plurality of different curvatures of substantially elliptical or polygonal configurations and the like are successively combined and fitted and fixed to the bearing hole 6 of the bearing case 8. The relative circumferential slip and rotation between the bearing hole 6 of the yoke 4 and the bearing case 8 is prevented by the contact area of a fitting part itself having the distorted circular or a non-circular section.
