    Abstract: An object of the present invention is to provide a method of manufacturing a rotational shaft having a worm, wherein a worm portion has a small bending amount. According to the method of the invention, a worm portion is formed at a worm forming portion by a rolling process with rolling dies, and a small diameter portion is formed at least at one axial end of the worm forming portion, wherein a diameter of the small diameter portion is smaller than a diameter of a bottom of a worm tooth to be formed at the worm forming portion, so that surplus material portion of the worm forming portion can flow toward the small diameter portion.

    Abstract: In a method for processing a rotor used for a supercharger and the like, a slanted rolling machine is used having rolls designed such that the rolls are arranged about a pass line along which a material to be molded advances. Each roll is of corn shape and has a plurality of spiral-shaped grooves formed on its side surface. A shaft member made from iron or a similar material is inserted into an aluminum alloy tube. The aluminum alloy tube with the shaft member inside it is continuously fed to the slanted rolling machine along the pass line. Then, the periphery of the aluminum alloy tube is rolled/spread by the rolls for forming spiral shaped teeth from the tube material and for metallurgically attaching the tube to the shaft member.

    Abstract: A worm is formed by rolling to reduce the number of processing steps while ensuring the worm accuracy satisfactorily. A work material is positioned between a first rolling die (100) and a second rolling die (101) by rotation of the rolling dies and a servomotor (76) for feeding the work material. When the lead angle of a worm is large and there is a large difference between the finished diameter and the blank diameter, the lead angle changes during the progress of rolling process, resulting in occurrence of through-feed. A slide plate (55) is freely slidable on a slide (53). Therefore, when through-feed occurs owing to the lead angles of the first and second rolling dies (100) and (101) and the workpiece, the slide plate (55) slides freely, and this is detected with a detecting sensor. The rotation of the first and second rolling dies (100) and (101) is stopped. Then, the first and second rolling dies (100) and (101) initiate reverse rotation, and at the same time, the slide plate (55) also initiates movement in the reverse direction. Thus, rolling is started. Thereafter, similar processing is repeated to perform rolling.

    Abstract: The invention relates to a machine element which is provided, at least over part of its axial length, with first toothing (2.1) in the form of threads, running on its cylindrical lateral surface, for a threaded drive. This is distinguished in that the threads are produced by means of a continuous shape rolling process in the axial direction, as is known per se, the continuous shape rolling process being used in a partially continuous manner corresponding to the desired axial extent of the threads.
