Spur gear differential e.g. planetary gear system, for branching input power to be supplied to two shafts through power input in automotive industry, has ring gears synchronized with each other regarding toothing geometry

摘要

The differential has a planet carrier (3) i.e. disk body, rotating around a circulation axis (X), and two sets of rotary plan parts (P2) standing in engagement with ring gear inner teeth (1a, 2a) of ring gears (1, 2). The rotary plan parts are rotatably coupled with each other and against one another. The ring gears are synchronized with each other regarding a toothing geometry, so that a head circle (K1) of one of the ring gear inner teeth is larger than a sum of head circle diameter of the plan parts and double distance of an axis of the plan parts from an axis of one of the ring gears.
