STEP-UP GEAR MECHANISM AND WIND POWER PLANT AND ELECTRIC DRIVE FOR VEHICLES HAVING SUCH A STEP-UP GEAR MECHANISM
The invention relates to a step-up gear mechanism (1) which is lighter while having the same power than a conventional planetary gear and which, in addition, is less sensitive to impact and shock stresses. The invention further relates to a wind power plant and to an electric drive for vehicles having such a step-up gear mechanism. The invention relates to a planetary gear having gearwheel and drive belt components. Conventional planetary gears with gearwheels can reliably transmit high torques and powers. By the combination with drive belts (20), which drive shaft wheels, fewer gearwheels are necessary and the weight is reduced. In addition, the drive belts act as a damping element which absorbs and dampens impact and shock stresses. The transmission to the planetary shaft wheels and the coupling by means of drive belts to at least one fast-rotor unit are carried out by the planetary shaft wheels of the planetary unit(s). Each planetary unit is coupled to a fast-rotor shaft wheel of a fast-rotor unit by means of its own drive belt.
