Abstract
A torsional vibration damper housing includes four or more components that are attached to one another utilizing a high intensity welding procedure. In particular, the housing includes a circular hub portion cut or machined from a flat plate. Attached to the hub portion is an inner hollow cylinder that is preferably cut to length from available tube stock. A pair of circular flat plates are attached to, and extend radially away from, the inner hollow cylinder. Finally, an outer hollow cylinder, which is also preferably cut to length from available tube stock, is attached adjacent the outer edges of the circular flat plates to define a housing having a sealed annular chamber with a rectangular cross section. The multi-component structure allows for the use of a ring mass having a nearly rectangular cross section and the use of relatively thinner walled housing components.
