摘要： Apparatus for making a metallic, non-rotationally symmetric ring with substantially constant wall thickness about its circumference, in particular a cam ring, from a circular ring, includes frame bed and a forming tool which is supported by the frame bed. The forming tool has an inner contour which approximates a finished contour of a non-rotationally symmetric ring, and includes two die members which are constructed in the form of two flat disks in opposite disposition and movable back and forth. Arranged in an area between the die members is an endless transport belt which is constructed to move in a production clock cycle and to move transversely to the die members. The transport belt has an upper strand extending in immediate proximity underneath the die members.

摘要： In a method of making a metallic, non-rotationally symmetric ring with substantially constant wall thickness about its circumference, in particular a cam ring, from a circular ring, a circular ring is mechanically machined on both inner and outer sides with an edge-shortening form element and then intermittently fed by a transport belt to an area between two continuously closing and opening die members. The transport belt is hereby positioned with its upper strand below the die members. After closing the die members, the circular ring is shaped through cold forming to a non-rotationally symmetric shape whereby the die members continue to maintain the closed position momentarily before being opened for removal of the non-rotationally symmetric ring from the area between the die members.

摘要： A method for producing steel rolling bearing rings, starting from a hot-rolled tube, the structure of which is similar to a spheroidized structure and from which rings of the same continuous length are hot-cut while supplying a lubricant and, after cooling, are further processed. The hot-cutting takes place at a temperature below the transformation temperature of the rolling bearing steel used but above 720° C., with subsequent cooling in static air. From the blank ring a green or soft ring of a rolling bearing ring is produced with narrow tolerances of its shaped elements by an optimally timed multistage machining type of cold further processing operation, the main element of the cold further processing being a turning operation.
