Low-backlash Wolfrom-planetary gearing

摘要

The gear-train has the epicyclic gears supported within a housing. The holders and bearings of the rotary support (6) and of the first and second hollow wheel (4,8) are radially movable towards each other at least during assembly. The gear housing for the radial mobility of the separate parts is divided, with the divided parts (1,2,3) being screwed radially together when the gear is assembled. A radially movable roller bearing (13) is fixed axially in position by a spring disc (14).
