ABSTRACT:
A toothed rack (22) disclosed has a toothed forming face (24) of a novel construction for forming splines (42) in a thin-wall sleeve (36) of a power transmission member (28) by meshing of the rack and a toothed mandrel (26) with the sleeve therebetween to form the splines. The toothed forming face has leading, intermediate, and trailing tooth groups (40a, 40b, 40c) that perform the splining. The pitch line tooth thickness of the leading tooth group is at least equal to and preferably greater than the pitch line tooth thickness of the trailing tooth group which has an addendum of a greater height than the leading tooth group. The teeth of the intermediate tooth group have an addendum height that is shorter than the teeth of the trailing tooth group and preferably equal to the addendum height of the leading tooth group. The pitch line tooth thickness of the leading tooth group is equal to and preferably greater than the pitch line tooth thickness of the intermediate tooth group. The profile of the intermediate teeth from the tip to the root thereof is the same as the profile of the trailing teeth from the tip thereof toward the root thereof for the same distance. All of the teeth have faces defining the same pressure angle as each other.
