Spur gear planetary gearing with load balance

摘要

A spur gear planetary gearing arrangement capable of a load balance on the teeth of the gears incorporated therein. The sun gear of the planetary gearing arrangement is supported solely on the planetary gears and the planetary gears are, in turn, rotatably supported on a planetary gear carrier. The teeth of the planetary gears are in meshing engagement with an internally toothed ring gear. The ring gear is mounted in a gear box housing. The ring gear is elastically deformable to a specific degree approximately equal with the radial electricity of its tooth system thereon and independent from the housing.
