ABSTRACT:
The arrangement comprises an intermediate housing for a plural-rotor mainshaft of a rotary engine in which the housing is vertically split transverse to the shaft rotary axis, into two portions. Each housing portion, like the mainshaft itself, is of one-piece construction, the portions having interfaced circular bores in which to receive the mainshaft. Rotor journals integral with the mainshaft are eccentric for use with rotary pistons, and are dimensioned to fit through the bores. In addition, a large radial bearing journal, also integral with the shaft, carries a full sleeve-type bearing and is directly received by the bore formed in one housing portion; the journal and its bearing are directly supported by and wholly radially enclosed by only the one housing portion. Accordingly, none of the bearing support is overhung, and yet both housing portions are abutted and interfitted together to transmit loading therebetween.
