Abstract

In this planetary transmission, an inner sun gear (3) is provided with double helical toothing, is connected with the ability for radial and axial motion to an input shaft (1) and drives two parallel planetary gear sets (4a, 4b). These engage in the toothing of the inner sun gear (3) and in correspondingly toothed outer sun gears (10). The planet carriers (5a, 5b) assigned to the planetary gear sets (4a, 4b) are connected to one another by means of a double-joint coupling (6) and to the output shaft (7) via a further double-joint coupling (8). The planetary gear sets (4a, 4b) have no special bearing arrangements but are held in their position solely by their helical toothing and the inner sun gear (3) with its double helical toothing, allowing them to adjust independently of one another under load. This results in loading conditions which are so favourable that the selected radial dimensions of the transmission can be very small and that, nevertheless, rolling bearings can be used for the transmission shafts. Transmissions of this kind can be used with particular advantage for driving rolling-mill rolls, calenders and bending machines. <IMAGE>
