    摘要： A machining apparatus is of an in-feed type configured to machine an outer peripheral surface of a rotating tapered roller, and includes a rotating mechanism having a lateral pair of rollers on which the tapered roller is mounted, the rotating mechanism rotating the pair of rollers, and a grinding stone that is brought into contact with the outer peripheral surface of the tapered roller mounted on the pair of rollers. Each roller of the pair of rollers is shaped like a truncated cone. Small-diameter portions of the pair of rollers come into contact with a small-diameter portion of the tapered roller. Large-diameter portions of the pair of rollers come into contact with a large-diameter portion of the tapered roller.

    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 machine for producing a convex rolling surface for rollers. The machine includes a drum having on its outer surface a spiral groove for accommodating rollers being machined. A tool is made hollow and communicates with the drum disposed inside thereof. The tool has an inside surface which is a working surface corresponding to the outer surface of the drum. The tool is pressed against rollers being machine with the aid of a pressing means which is a pneumatic cylinder producing the desired rolling surface for rollers.
