Abstract
A gear system () comprising a main bearing (), a main gear () and two or more pinion shafts (). The main bearing () directly supports a torque inputting means () and defines a rotational axis (). The pinion shafts () are each arranged to mesh with the main gear () at an exterior surface () of the main gear () in such a manner that torque transmitted from the main gear () is split into a number of parallel torque paths corresponding to the number of pinion shafts (). At least the main gear (), and at least part of its meshes to the pinion shafts () are arranged within a perimeter defined by the main bearing (). The gear system () is compact due to the arrangement of the main gear () and meshes to the pinion shafts (). At the same time it is easy and cost effective to manufacture because the pinion shafts () mesh to the main gear () via the external surface ().
