一、滾制法花键的滚制系由辊子使毛坯产生局部变形实现的,与用滚丝机滚制螺纹的工艺相似。齿形是由于金属沿径向重新分布而形成的,所以毛坯直径总是比花键外径要小些。双辊滚轧花键的原理示于图1。毛坯 First, the rolling method Spline rolling system by the roller to produce local deformation of the blank achieved, and rolling thread rolling process similar. Tooth shape is due to the radial metal redistribution formed, so the rough diameter is always smaller than the spline diameter. The principle of the double-roll rolling spline is shown in FIG. 1. blank
