Gearbox i.e., hollow shaft gearbox, for use in drive in e.g. rotating tank turret, has teeth arranged over peripheral part of planetary gears that are arranged such that teeth engage with gearing and internal gears in different directions

摘要

The gearbox has a sun wheel (10) with a worm gearing (26), and ring gears (14) provided with internal gears (16). Teeth are arranged over a peripheral part of planetary gears (22). The planetary gears are arranged such that the teeth engage with the worm gearing and the internal gears in different directions. The planetary gears are rotatably arranged around axles that are inclinedly aligned with respect to a common axis of the sun wheel and the ring gears. The teeth are designed as individual teeth and formed in partial pyramidal shape or prismatoid shape. The internal gears are designed as helical gearings. An independent claim is also included for a drive.
