  • Patent number: 12044298
    Abstract: A differential gear assembly, and method for assembling such an assembly are provided. The differential gear assembly comprises a housing constructed of substantially identically shaped and sized housing plates, which each have an outer flange of a same diameter. The assembly further comprises an outer helical ring gear that is fixed to the housing, wherein outer helical ring gear comprises an inner flange for mounting to the outer flange of the first or second housing plate, wherein an inner diameter of the inner flange is smaller than the outer diameter of the housing plates. The inner flange of the helical ring gear can thus be held, e.g. clamped, between the outer flanges of the housing plates. In an alternative embodiment, the outer flange of one of the housing plates is held between the inner flange of the ring gear and the outer flange of the other of the housing plates.
