The invention is directed firstly to a gear mechanism for distributing the input torque from a drive to two or more outputs, comprising one or two rotationally symmetrical connection elements with in each case one flat connection surface for the rotationally fixed connection to two different machine or system elements or firstly to a machine or system element and secondly a chassis or foundation, wherein the two rotationally symmetrical connection elements are oriented in such a way that their axes of symmetry run coaxially with respect to one another and their connection surfaces face away from one another, wherein, furthermore, a gap is situated between the two connection elements, in which gap at least one anti-friction bearing is arranged as main bearing for mounting the two connection elements on one another, such that they can be moved rotationally about a main-bearing rotational axis which corresponds to the common axis of symmetry of both connection elements, and wherein at least one circumferential surface of a connection element is provided with a serration which runs around it, and wherein the non-serrated connection element has a section which faces the serration of the serrated connection element and has one or more cavities which are open towards the serration for receiving toothed gearwheels, wherein an end-side opening is provided in the non-serrated connection element for each gearwheel for discharging the respective output torque, and, approximately aligned with said opening, at least one closed annular region for supporting a bearing, which is arranged in the axial direction between the connection surfaces of the two connection elements, for the relevant gearwheel as the wheel bearing thereof, with the result that the relevant gearwheel rotates about an auxiliary rotational axis which is offset eccentrically with respect to the main-bearing rotational axis but is approximately parallel thereto, and meshes with the serration of the serrated connection element; and secondly is directed to a wind energy plant which is equipped with a gear mechanism of this type. |
