Description
[technical field] the present invention relates to wind-powered electricity generation gear-box technical field, a kind of wind power generation three-piece double-cycloid yawing speed reducer.
[background technique] yawing speed reducer is the special gear box that wind direction was aimed at or departed from the wind-driven generator group selection.Yawing speed reducer requires very high reliability: bearing capacity very much not broken teeth and output shaft is oil-proof.At present the product and the nation of main body entrance Mitsubishi heavy industry, Italian Bu Laiweini company fly sharp 707T.The subject matter of import yawing speed reducer is leakage of oil.Background technique has three kinds:
(A) level Four planetary reduction gear: (1) Nan Gaochi " Yaw gearbox for wind power generator " (200410064930); (2) heavy tooth company (200620111262); (3) peaceful machinery plant (200720125070); (4) Hua Rui company (200820014549) (Pyatyi planetary reduction gear); (5) Tianjin speed reducer company (200820075290); (6) ACE Semi's speed reducer company (200910034525).Subject matter: (a) planet wheel only has three, and bearing capacity is not high; (b) existing rubber oil sea (except that the Che Shi oil sealing) does not possess the compensation automatically of wearing and tearing back, and one wear and tear also can leakage of oil slightly for the twice oil sealing; (c) complex structure, axial dimension long, heavy, cost an arm and a leg.
(B) cycloid+two jogging stars: the problem of Tianjin speed reducer company (200320111939): (a) the scheme that does not propose to prevent leakage of oil; (b) slow speed turbine stage is because the mechanical load-balancing device that adopts sun gear to float, the planet wheel number can only 3-4 only, bearing capacity is not high.
(C) double cycloid: (200920127322.7) subject matter: (a) the anti-leakage of oil scheme that do not propose; (b) two bearings of output shaft being placed between left and right end plate and the hypocycloid wheel is the industrial robot reducer structure, and this moment, bearing went out 2-3 model greatly.
[summary of the invention] the object of the invention be to provide a kind of bigger than multistage planet bearing capacity, output shaft is oil-proof, short in light weight and the wind power generation three-piece double-cycloid yawing speed reducer that cost is low of axial dimension.
(1) three pieces type retarder: be the cycloid transmission device of latest development, Shanghai Communications University, Dalian gear expert has done long-term theoretical research to this.Advantage: (1) bearing capacity increases by 50%; (2) improved rotary arm bearing; (3) pin tooth and pin stress equalization.
(2) double cycloid transmission: the engagement characteristics of double cycloid are that the cycloidal equidistance curve gear of envelope each other is as the conjugate curve gear mechanism.Advantage: (1) hypocycloid gear ring replaces pinwheel, and is simple in structure, part is few in addition; (2) the single-stage reduction speed ratio is very big, it is said to reach 200 (" the cycloid variable-speed motor that does not have pinwheel " mechanical transmission 2006.04); (3) hypocycloid gear ring and external tooth cycloid wheel are pure rolling, the engagement of perfect lubrication state, therefore under the input power same case, the volume of retarder can be reduced 1-2 grade.
(3) comparison of cycloid and NGW planet: (a) reduction speed ratio is big; (b) cycloid wheel with partly bury tooth and have the high bending ability, thereby the NGW planet height of three planet wheels of bearing capacity ratio; (c) cost is less than half of NGW planet.Shortcoming: efficient is low slightly.
[technological scheme] two technological schemes are as follows:
(1) improves the cycloid impact resistance: (a) partly bury toothing, make gear pin have very high bending ability; (b) in the W output mechanism, make the cantilever pin become freely-supported with all carrying ring, improved the crooking ability of pin;
(2) prevent leakage of oil: (a) shoe cream room is arranged at the support bottom, and there is an oil shield output shaft block bearing top; (b) device is formed Che Shi seal ring (seeing into big elder generation " mechanical design handbook " volume 2 for details) by O type circle and thin lips and teeth RunddichtringO on the output shaft.
[beneficial effect] contrasts background technique with the present invention, (200410064930) of patented invention particularly, and its novelty, creativeness and practicability are embodied in: (a) double reduction only, axial dimension is short, in light weight, easy to maintenance; (2) cycloidal gear teeth and partly bury the tooth needle pin can broken teeth, thereby have the bearing capacity of three planet wheels big than only; (b) price of existing cycloidal reducer is less than half of NGW planetary reducer, thereby manufacture cost will be hanged down 40-55%; (c) oil-proof.
