Ultra-compact gearbox and generator integrated structure

Abstract

The invention discloses an ultra-compact gearbox and generator integrated structure which comprises a gearbox body and a generator body, one end of the gearbox body is arranged in one end of the generator body, a gearbox rear end cover is fixed to one end of the gearbox body, a secondary planet carrier is fixed to one end of the gearbox rear end cover, and a secondary planet carrier is fixed to the other end of the secondary planet carrier. A low-speed shaft is arranged at one end in the gearbox body; by designing the generator body, the gear box body and the gear box rear end cover, the connecting structure of the gear box and the generator is more compact, the weight is saved, the cost is low, meanwhile, the generator rotor is directly installed on the gear box rear end cover, the centering requirement can be completely met through machining, and the machining efficiency is improved. The generator centering link in the assembling process is omitted, assembling working hours are saved, the generator and the gear box are integrated, the gravity center of the generator is in the front, a gear box torque arm can be omitted, and the generator is directly connected with the bearing seat through the front end connecting end cover.

Description

technical field [0001] The invention belongs to the technical field of wind power generators, and in particular relates to an ultra-compact gearbox and generator integrated structure. Background technique [0002] With the development of wind turbine technology, there are mainly three technical routes for wind turbines in the industry, namely direct-drive units, semi-direct-drive units, and double-fed units. In recent years, high-power units have become the main factor for the future competition of enterprises, because semi-direct drive units take into account the advantages of direct-drive units and doubly-fed units. The development has been favored, and the wind power market has entered the stage of parity. The market requires wind turbine manufacturers to continuously reduce the manufacturing cost of the whole machine, and put forward higher requirements for the performance of the unit. In the structure of the semi-direct drive unit, the gearbox and generator Cost and pe...
