Abstract
A method of manufacturing an annular transmission component for a vehicle includes providing a tube defining an annular wall having a predetermined diameter. The tube is cut to a form a tube blank having a first end and a second end. The tube blank placed into a forming machine and the first end of the tube blank is rolled relative to the second end of the tube blank forming an annular U-shaped channel defined between the first and the second end.

A method of making an annular transmission component for a vehicle, the method comprising:
- placing a tube blank having first and second ends into a forming machine;
- and
- rolling the first end of the tube blank radially and axially relative to the second end thereby forming an annular, arcuate shaped channel between the first end and the second end.
A method of making an annular shroud, the method comprising:
- situating a tube in a forming machine, the tube having a first end, a second end and an annular wall of a generally constant initial diameter between the first end and the second end;
- roll forming the tube to cause the first end of the tube to have a different diameter than the initial diameter and to shape the annular wall to have an arcuate shape between the first end and the second end;
- and
- supporting the second end in the forming machine to maintain the initial diameter near the second end.
