ABSTRACT:
An improved combination journal and thrust bearing particularly suited for use in slant axis rotary mechanisms of the type including a housing defining a chamber with an operating cavity, a shaft journalled in the housing and including an angularly offset portion within the chamber, and a rotor within the chamber journalled on the angularly offset portion. The improved bearing includes an hour glass configuration in the angularly offset portion and the provision of a ring-like bearing structure operatively interposed between the angularly offset portion and the rotor to slidably journal the rotor on the shaft. The radially inner surface of the bearing is configured to substantially mate with the hour glass configuration.
