摘要： A processing apparatus includes two feed drums, each having an outer periphery formed with a spirally extending threaded guide surface and adapted to be driven to rotate, disposed so as to extend parallel to each other, and the feed drums are used to pass a roller through between the feed drums by the rotation thereof while the roller is caused to rollingly contact the mutually opposed threaded guide surface, and also includes a grinding stone for processing a crowned portion of the roller passing thorough between the feed drums. The threaded guide surface of the feed drums is divided into two axially juxtaposed divided threaded surface areas so that an outer peripheral surface of the roller can be supported at two anteroposterior locations.

摘要： A processing method for a bearing is capable of shortening a lead time without the need for carrying out super finishing (mirror grinding). A component of a bearing is finished while chucking the component by a chucking device. Hardened steel cutting and grinding are carried out while chucking the component without releasing the chucking by the chucking device.

摘要： A gerotor device includes a rotor having outwardly extending teeth and a stator having inwardly extending teeth. The inwardly extending teeth are formed by rollers each of which is received in a respective roller pocket in the stator. Each roller pocket has a maximum pocket width measured perpendicular to a pocket centerline. Each roller pocket defines a roller bearing surface having a first side that follows a first radius and a second side on an opposite side of the centerline that follows a second radius. Each radius is greater than ½ the maximum pocket width. Each roller pocket has an edge pocket width between a first pocket edge where the pocket transitions to a generally cylindrical section in the stator and a second pocket edge on an opposite side of the centerline. The edge pocket width is less than the maximum pocket width.
