<p>The invention relates to a power transmission, in particular reduction gearing, having an input shaft (1), a pinion shaft (2) and at least two output shafts (3), wherein the input shaft (1) is connected to the pinion shaft (2) via at least one spur gear stage, and the pinion shaft (2) is connected to the at least two output shafts (3) via a divider stage in which at least two helically toothed pinions (10a, 10b) which are arranged on the common pinion shaft (2) mesh in each case with one gearwheel (11a, 11b) of the at least two output shafts (3), on which output shafts are arranged output pinions (12a, 12b) for a downstream toothed ring (13). According to the invention, it is provided here that the at least two pinions (10a, 10b) of the pinion shaft (2) have a different module and/or the at least two output shafts (3) have a different center distance with respect to the pinion shaft (2). In this way, it is possible in particular to select a larger helix angle in the spur gear stage. Increased running smoothness and a longer service life of the power transmission can be achieved by means of such an optimization of the spur gear stage in particular in the case of high levels of power and high circumferential speeds.</p> |
