<p>The invention relates to mechanical engineering and can be used, in particular for large wind power stations as a drive between a windwheel and a generator. The inventive planetary gearing comprises a body, central wheels and a carrier provided with pinions arranged thereon with the aid of anvils. The gearing pinions are embodied in a multicrown form and have one working surface at one concrete direction of a torsion torque. Small gear rims of all pinions are simultaneously engaged with the same central wheel of the internal gear, the number of pinions whose large gear rims are engaged with the same crown of the central wheel of the internal gear being less at least half as large. Said invention makes it possible to reduce the mass of the planetary gearing. For wind power stations of 660 kW, the mass reduction can reach 60 %, which is high in relation to the mounting height of the planetary gearing.</p> |
