ABSTRACT:
A gear system includes a housing and an intermediate ring gear movably carried on a support hub coupled to an output shaft. The ring gear is driven by an input pinion gear through a running tooth system and drives the support hub through a coupling tooth system. Misalignment of the gearings due to housing, shaft or support deflections under load are compensated by providing an arcuate axial tooth profile and radial clearance in the coupling tooth system. The coupling tooth system includes lubricant confined between a pair of sealing discs. In an alternate embodiment, the ring gear is carried on spherically configured rings of the support and the ring gear includes mating spherically configured rings with suitable clearance between the spherical surfaces. Engagement between the mating spherical surfaces generates the radial force required for adjustment of the ring gear while maintaining radial tooth clearance within the coupling tooth system. As a result, the coupling tooth system transmits torque forces exclusively.
