Abstract
The method for forming a face spline in a constant velocity joint includes forming a preliminary face spline on a base material through hot forging to produce an intermediate formed product, and additionally forming the preliminary face spline into the face spline through cold forging. The preliminary face spline has a tooth profile including inclined side surfaces and a bottom located between the inclined side surfaces, and during the cold forging process, pressure is applied to the inclined side surfaces so that the material flows toward the bottom.
Claims11
A method for forming a face spline in a constant velocity joint, comprising:
- forming an intermediate formed product by forming a preliminary face spline on a base material through hot forging;
- and
- additionally forming the preliminary face spline into the face spline through cold forging,
- wherein the preliminary face spline has a tooth profile including inclined side surfaces and a bottom located between the inclined side surfaces, and
- wherein, during the cold forging, pressure is applied to the inclined side surfaces of the preliminary face spline so that material flows toward the bottom, thereby forming the face spline.
