ABSTRACT:
A sealed generator housing has two components, one of which includes a circumferential bore having a cylindrical internal support surface, and the other of which has an end wall equipped with mounting segments, each of which has a mounting surface which contacts the support surface from within, centering the circumferential wall with respect to the end wall, while permitting relative axial sliding of the components. A gap is present between the two components, which permits such relative sliding due, for instance, to thermal expansion and contraction. An annular sealing member extends axially across the gap at the exterior of the housing and is entirely surrounded by a length-adjustable clamping strip exerting inwardly oriented pressure on the sealing element. The annular sealing element has bulges at its internal surface, such bulges being received in corresponding circumferential grooves of the two components of the housing extending alongside the gap. The annular sealing element is supported from within by support portions rigid with one of the components.
