It has been known. The counterbalance wheels here each have a blind hole length, and each counterbalance wheel is fitted in the processing direction with the rear wheel of the driven wheel group and is only in mesh with a part of this length, In the cover of the differential mechanism cage, there is an elongate journal for supporting.

成されていることにより単純化される。The above-mentioned problems can be solved by the fact that the balancing wheel, which meshes with the driven wheel of small diameter, is axially supported directly on the driven wheel of large diameter. Thus, in particular, the support means can be moved away from these driven wheels towards the center of the cage. The required structural length is reduced. It is further simplified by the fact that the differential cage has a housing part in which the entire cavity for accommodating the balancing wheel is constructed as an axial cavity with a constant internal area.

る。Function: The blind hole does not need to be dimensionally accurate. In contrast to the above, the opening for the balancing wheel, which is configured as a void, is simple. A mode in which a space for the opening for accommodating the driven wheel is also prepared is particularly convenient. In this case, for example, a shaped tube can be completely processed through the internal space.
