ABSTRACT:
A driveshaft arrangement is provided for use with trochoidal rotary expansible chamber devices to afford increased driveshaft diameters for such devices. The driveshaft arrangement includes a cluster gear assembly for driving connection between a gear coaxial and mounted for rotation with the rotor and the driveshaft. A cluster gear assembly has a first gear rotatable about the centerline axis of the driveshaft and mounted in driving engagement with the rotor gear. In the case of an inner envelope type rotary device, the first gear is a pinion having a pitch diameter greater than heretofore conventionally required, thereby permitting the diameter of the driveshaft to be increased. In the case of an outer envelope type device, the rotor gear is a pinion with a pitch diameter greater than typically desired enabling an increased diameter for the driveshaft. From the first gear there follows a series of further gear drive interconnections leading to a final pinion gear connected to the driveshaft for coaxial rotation therewith. The last pinion gear meshing with the final pinion gear is adjustably mounted for an operator to set the proper timed relationship of the cluster gear assembly with compensation for machine tolerances.
