摘要

The low-backlash planetary gear has a ring gear (18) with a conical toothing (19) and another ring gear (21) with another conical toothing (22), where the former ring gear is arranged adjacent to latter ring gear. The former toothing of the former ring gear and the latter toothing of the second ring gear have same number of teeth. The third and fourth toothings (30,31) have planet gear (27) with same radial dimensions but with different numbers of teeth.
