Abstract
A torsional vibration damper has a rotational axis and an annular housing having inner and outer members. The housing has an annular channel in which an inertia member is received. The channel has axially extending walls and is closed by an annular cover plate to retain the inertia member The inner edge of the cover plate is received in a rabbet in the inner channel wall and is joined to the wall by means of a weld. The inner and outer members are connected by an annular weld at a central hub. The weld may extend between two radial extremes which are separated by a distance substantially greater than the thickness of weld. The damper is easier to manufacture and assemble and has greater structural integrity.
