摘要： A planetary gear (15b) mounted on a central shaft (29b) that turns together with the crankshaft (17b) drives an accessory group of a motor vehicle, in particular a radiator fan (1b) of an internal combustion engine temperature-dependent controllable by a hydraulic friction clutch (5b). The planetary gear has three gear components rotatable with respect to each other together with the shaft (29b) around a common axis of rotation (27b), which form a sun wheel (33b), a ring gear (35b) and a planet carrier (39b) provided with planet wheels (43b). The gear components are rotatively mounted with respect to each other on rolling bearings (49b, 51b, 59b) clamped between bearing members (167, 169) of the shaft (29b) in a common bearing force path together with parts of the gear components, in order to compensate axial play. Lubricant conveyor means (91b) associated to the planetary gear (15b) supply liquid lubricant to the rolling bearings (49b, 51b, 59b) when the gear components rotate with respect to each other. The planetary gear (15b) is designed as a gear whose speed of rotation can be changed-over, and locked in direct drive. In order to allow the rolling bearings (49b, 51b, 59b) exposed to the variable motion in direct drive to be lubricated in spite of being locked, the rolling bearings are arranged in radially inwardly open but radially outwardly tight lubricant pockets (129, 133, 141) which extend over the radially inner running races of the rolling bearings and which are filled with lubricant when the internal combustion engine is started by temporarily operating the planetary gear (15b) in a speed increasing mode.

摘要： According to an illustrative embodiment of the invention, a planetary gear box is combined with an electric generator of a motor-vehicle. The planetary gear box comprises a free wheel and a gear change clutch. Such, the transmission ratio of the planetary gear box is changeable. The components of the gear box are arranged at least partially in axially overlapping relationship so that a small overall axial dimension is obtained.
