Abstract
The invention relates to a wind power turbine and a gearbox for same. In wind power turbines, the incoming moment is transmitted from a hub to a gearbox via a shaft, and from the gearbox to a generator. According to the invention, the gearbox is at least partially built into the shaft and/or the shaft is at least partially embodied as a rotary gearbox housing. The resulting compact construction not only renders the wind power turbine more compact and therefore significantly more economical and lighter, but in the event of a suitable design and use of a coupling gearbox, the moment generated can be transmitted in a highly secure manner.
Claims10
A wind power turbine having a gearbox, a hub, and a shaft having a cavity;
- wherein a torque can be transmitted from the hub via the shaft to the gearbox;
- wherein at least part of the gearbox is arranged within the cavity in the shaft so that the shaft forms a rotating gearbox housing;
- wherein the gearbox is a multi-stage planetary gearbox;
- wherein at least two stages with gear trains of the multi-stage planetary gearbox are arranged entirely inside the cavity of the shaft;
- wherein the wind power turbine further comprises a prestressed rolling-element bearing;
- wherein the shaft is mounted in the prestressed rolling-element bearing;
- wherein the prestressed rolling-element bearing is divided into two axially;
- and
- wherein the at least two stages of the multi-stage planetary gearbox which are arranged within the cavity in the shaft are axially arranged in-between the two prestressed rolling-element bearings.
