The invention has the advantages that (a) the reducer only has two-stage deceleration, has short axial size, light weight and convenient maintenance, and the bearing capacity of the reducer is larger than that of a reducer which only has three planetary wheels because teeth of cycloid gear teeth and the semi-embedded wheel pin do not break; (b) the price of the traditional cycloid reducer is less than half of that of an NGW planetary reducer, thus the manufacturing cost is reduced by 40-55%; and (c) the reducer has no oil leakage.
Description
[technical field] the present invention relates to the wind turbine gearbox technical field, a kind of wind power three-cycloid yawing 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 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 the Che Shi oil sealing) does not possess afterwards auto-compensation of wearing and tearing, and the twice oil sealing slightly weares and teares also can leakage of oil; (c) complex structure, long, the heaviness, expensive of axial dimension.
(B) cycloid+secondary planet: 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) do not propose the oil-leakage-prevention scheme; (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 greatly 2-3 model.
[summary of the invention] the object of the invention be to provide a kind of larger than multistage planet bearing capacity, output shaft is oil-proof, short lightweight and the wind power three-cycloid yawing reducer that cost is low of axial dimension.
(1) three pieces type retarder: be the cycloid transmission device of latest development, Dalian hands over the gearwheel expert this to be done long-term theoretical research.Three pieces type refers to increase a slice wheel in two cycloid wheel of tradition, and the phase angle of three wheels is 120 °, and adopts and partly bury toothing.Advantage: (1) bearing capacity increases by 50%; (2) improved rotary arm bearing; (3) pin tooth and pin stress equalization.
(2) the NGW planet that compares of three-disk cycloid: (a) reduction speed ratio is large; (b) cycloid wheel with partly bury tooth and have the high bending ability, thereby the NGW planet of three planet wheels of bearing capacity ratio is high; (d) cost is less than half of NGW planet.Shortcoming: efficient is slightly low.
[technological scheme] two large technological schemes are as follows:
(1) improves the cycloid impact resistance: (a) partly bury toothing, make gear pin have very high bending ability; (b) slow wire feeding wire cutting technology machined needles alligator hole in the usefulness makes its adjacent holes apart from deviation≤0.01-0.015; (c) 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) at output shaft device Che Shi seal ring.Seal ring is comprised of O type circle and thin lips and teeth RunddichtringO, has the rear automatic elastic compensating function of wearing and tearing, nothing leakage and anti--55 ℃ of excellent specific properties such as low temperature (seeing into large elder generation " mechanical design handbook " volume 2 and the relevant paper of sealing for details).
[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, lightweight, 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 large 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.
[description of drawings] Fig. 1. embodiment of the invention structural representation
[embodiment] encyclopaedizes the present invention below in conjunction with accompanying drawing:
With reference to Fig. 1. a kind of wind power three-cycloid yawing reducer, the two-stage cycloid that is comprised of support, W output mechanism, cycloid wheel, gear pin, pin wheel housing, capacity eccentric bearing and input shaft (1) and output shaft (11) is in series, and wherein: the level output shaft is bearing in front support (18) endoporus with bearing at a high speed; Slow speed turbine stage capacity eccentric bearing Z is contained at a high speed level output shaft shaft extension end, and output shaft (11) is bearing in support (10) endoporus with bearing, it is characterized in that:
