Abstract
A differential drive has a drive housing in which a drivable differential carrier (1) is rotatably supported. The differential carrier accommodates straight-toothed and helically toothed output gears (4, 5). The gears (4, 5) are connected to each other via differential gears (12, 13). A first group of differential gears (12) engages one of the output gears (4), with a second group of differential gears (13) engaging the other output gear (5). Each of the differential gears (12) of the one group engage at least one of the differential gears (13) of the other group. The teeth of the output gears (4, 5) are held in cylindrical apertures (6, 7) of the differential carrier (1). Also, the differential carrier, at least at one end, is indirectly supported in the drive housing via one of the output gears (4) or an output shaft (24) connected thereto.
