Wolfrom gearbox, has planetary gears exhibiting tolerance with ring gears and sun wheel in outer and inner engaging portions, respectively and braced with wheel and ring gears in circumferential direction of gearbox in tolerance-free manner

摘要

The gearbox (1) has ring gears (3) surrounding a sun wheel (2). Planetary gears (5a, 5b) are radially rotatably arranged between the sun wheel and the ring gears. The planetary gears exhibit a tolerance with the ring gears in radial outer engaging portions (6a, 6b) and with the sun wheel in radial inner engaging portions (7a, 7b). The planetary gears are spaced apart from each other in a circumferential direction of the gearbox such that the planetary gears are spring-loaded and braced with the sun wheel and the ring gears in the circumferential direction in a tolerance-free manner.
