Abstract
The base plate and the exciter housing in the vibratory compactor of this invention comprise a one-piece casting of ductile nodular iron. The exciter housing portion of that casting, located at the front of the base plate, has coaxial holes in its opposite side walls, each large enough to receive the exciter axially. In each such hole is axially slidably received a substantially cylindrical bearing support into which a bearing for the exciter shaft is coaxially press fitted. Tab portions on each bearing support, projecting radially beyond its cylindrical surface, overlie the exterior surface of its housing side wall and provide for securement of the bearing support to that side wall by means of bolts.
