Abstract

1384329 Rolling mills VSESOJUZNY ORDENA LENINA NAUCHNO - ISSLEDOVATELSKY I PROEKTNO - KONSTRUKTORSKY INSTITUT METALLURGICHESKOGO MASHINOSTROENIA 13 July 1972 32718/72 Heading B3M A roll 1, which is suitable together with other similar rolls for rolling helical teeth on a workpiece 3, is provided with a frusto-conical portion b, Fig. 1, which initially contacts the workpiece, followed by a parallel portion a. The thread pitch and angle between adjacent tooth flanks are different for the teeth in the two portions. The crown of each tooth in portion b is of ridged form, with the inclination of the two elements of each ridge being related to the angle of skew α of the roll axis relative to the workpiece. Three such rolls may be arranged around the periphery of a workpiece.
