ABSTRACT:
An improved rotor and gear assembly for rotary mechanisms of the trochoidal type, in which a rotor having a central bore is mounted for rotation on a shaft, and an internally toothed ring gear is secured to a side face of the rotor for engagement with a stationary gear to maintain phasing between the rotor and its trochoidal housing during the planetary and rotary motion of the gear within the housing. The ring gear is mounted on the rotor by resilient tubular pins circumferentially disposed, the pins being angularly slanted with respect to the rotor axis in such a manner as to maintain concentricity of the rotor and gear while permitting differences in thermal expansion therebetween, restraining the gear from axial displacement, and providing resilience for intermittent circumferential shock loading of the gear without imposing undue stresses or causing distortion of the gear or the rotor.
