ABSTRACT:
An improved slant axis rotary mechanism including a housing defining a chamber having radially inner and outer spherical walls interconnected by opposed, generally radially extending side walls, a shaft journalled in the housing and having an angularly offset portion within the chamber, a timing gear within the chamber at one side thereof and surrounding the shaft, a rotor journalled on the angularly offset portion within the chamber and having a spherical hub and a peripheral, radially outwardly extending flange extending from the hub, and a ring gear carried by the hub on one end thereof and meshed with the timing gear. In the inventive mechanism, the included angle between opposite portions of the flange on the side opposite from the gears is less than 180.degree. thereby enabling the thickness of the flange to be increased, or the wobble angle to be increased, or combinations of the foregoing.
