Description
Technical field
The utility model relates to semi-direct driving wind power generator group step-up gear.
Background technique
The advantage of wind-power electricity generation does not need fuel, does not account for the arable land, does not pollute, and operating cost is low, because wind-power electricity generation does not have fuel problem, also can not produce radiation or atmospheric pollution.THE WIND ENERGY RESOURCES IN CHINA is very abundant, and it is a kind of clean renewable energy sources, and wind-power electricity generation industry development prospect is boundless.Impeller on the blower fan drives main axis rotation under the effect of wind-force, realized wind energy is converted to the process of mechanical energy, and the rotor that the main shaft of rotation drives generator again rotates the process that has then realized mechanical energy is converted to electric energy.Because the rotating speed of wind wheel is lower, and the rotating speed of generator is higher, needs to dispose a speedup box like this between generator and main shaft, and the gearbox output shaft rotating speed brought up to the desired rotating speed of the rotor of generator is complementary.Therefore, require semi-direct driving wind power generator group step-up gear velocity ratio big, compact structure, volume is little, and specific power is big, and transmission progression is few, and mechanical loss is low, the reliability height, operation maintenance is convenient.
The model utility content
The technical problems to be solved in the utility model is: a kind of semi-direct driving wind power generator group step-up gear is provided, and velocity ratio is big, compact structure, and volume is little, and specific power is big, and transmission progression is few, and mechanical loss is low, the reliability height, operation maintenance is convenient.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of semi-direct driving wind power generator group step-up gear, described gear-box has body, be fixed on the ring gear on the body, planet carrier, first order planet wheel, planet pin, second level planet wheel, sun gear, the output shaft of band coupling, the output body, described planet carrier have be mutually permanently connected before, back side panel, first order planet wheel and second level planet wheel are by before being installed in before and after the bearing, between the back side panel, first order planet wheel and second level planet wheel are installed on the planet pin with one heart, the front side plate engagement of ring gear and planet carrier, first order planet wheel and ring gear engagement, second level planet wheel and sun gear engagement, sun gear is connected with output shaft.
Further, described second level planet wheel is connected with the planet pin interference.
Further, it is fixedly connected that the forward and backward side plate of described planet carrier adopts the pin of band endoporus.
Further, described sun gear adopts spline to be connected with output shaft, radially adopts the positioning bearing location.
The beneficial effects of the utility model are: semi-direct driving wind power generator group step-up gear speedup velocity ratio of the present utility model is big, compact structure, and volume is little, and specific power is big, and transmission progression is few, and mechanical loss is low, the reliability height, operation maintenance is convenient.
