The inner part of an inner chamber of a backward rotating body is fixedly connected with a driving motor, the wheel hub is fixedly connected with a speed reducer, the driving motor is connected with the speed reducer by a universal joint and a driving axle, an output axle of the speed reducer is connected with a steering mechanism of a cone gear, the output end of the steering mechanism of a cone gear is connected with a worm rod and a worm wheel engaged with the worm rod is fixedly sheathed on the propeller blade. The variable propeller pitch driving device for a wind force generator makes use of a rotor and a stator of a driving motor as connecting components between a rotating part and a fixed part. Carbon brushes, sliding rings or rotating joints are saved. An air gap is arranged between the rotor and the stator of the driving motor, thus, the utility model has the advantages of no abrasion operation, long service life, safe electric generation and maintenance cost saving.

Description

A kind of drive unit with variable airscrew pitch of wind driven generator
Technical field
The utility model relates to a kind of drive unit with variable airscrew pitch of wind driven generator.
Background technique
At present, the high-power permanent magnet direct wind-driven generator group of producing all is equipped with drive unit with variable airscrew pitch both at home and abroad, this drive unit with variable airscrew pitch has two kinds of structural types usually, and a kind of is to adopt actuating motor to regulate pitch, and another kind is to regulate pitch with hydraulic system by lever.These two kinds of drive unit with variable airscrew pitch all must use transition member to handle the connectivity problem of rotating part and standing part, and the transition member of actuating motor is slip ring and carbon brush, and hydraulic system then will be used swivel joint.No matter be slip ring, carbon brush or swivel joint, all there is the rotation wear problem in the working procedure, working life is short.In order to guarantee the reliable operation of wind power generating set, must to transition member regular change maintenance, both increased maintenance expenses, influence the generator set generating again.
Summary of the invention
The purpose of this utility model provides a kind of straight connection type drive unit with variable airscrew pitch of wind driven generator that does not have the wearing and tearing of rotating.
In order to realize above-mentioned purpose, the drive unit with variable airscrew pitch of wind driven generator that is provided, comprise and be fixed in epitrochanterian wheel hub, blade is housed on the wheel hub, its structural feature is to be connected with drive motor in the inner chamber of solid of rotation, on wheel hub, be connected with speed reducer, drive motor is connected with speed reducer with live axle by universal joint, on the output shaft of speed reducer, be connected to cone gear steering equipment, cone gear steering equipment comprises two pairs of cone gear pairs, the active cone gear of first pair of cone gear pair wherein is fixed on the output shaft of speed reducer, be fixed on the transmission shaft with the driven bevel gear of this active cone gear engagement, the active cone gear of also affixed second pair of cone gear pair on this transmission shaft, be fixed on the worm screw with the driven bevel gear of this active cone gear engagement, be fixed on the blade with the worm gear of worm meshing.
Above-mentioned bevel-type reversing gear is supported on the wheel hub by fixing frame.
The working principle of drive unit with variable airscrew pitch of wind driven generator provided by the utility model is: in that wind speed is moderate need not feather the time, disconnect the power supply of drive motor, at this moment, blade drive wheel hub rotates synchronously under the effect of wind-force, the rotation of wheel hub drives the speed reducer body again and rotates, and then the drive drive shaft turns, the rotation of live axle drives the rotor rotation of drive motor, realizes being connected of rotating part and standing part by the rotor and the stator of drive motor; When rotation excessive when wind speed, blade surpasses the rated speed of blade; in order to protect wind power generating set; at this moment; connect the power supply of drive motor, drive motor work, drive shaft turns; drive speed reducer work by live axle; by speed reducer by cone gear steering equipment drive worm screw, worm gear rotates, and changes the angle that facings the wind of blade by the rotation of worm gear, realizes the purpose of feather.
Learn by above narration, the utility model is to utilize the rotor of drive motor and stator as the connected element between rotating part and the standing part, carbon brush, slip ring or swivel joint have been saved, owing to have air gap between the rotor of drive motor and the stator, thereby realized not having the wearing and tearing operation, long service life, it is safe and reliable to generate electricity, and has saved maintenance expenses.
