Description
[technical field] the present invention relates to wind-powered electricity generation gear-box technical field, a kind of wind power generation three-piece cycloidal variable propeller reducer.
[background technique] variable paddle speed reducer of the present invention is in order to change the blade angle of facining the wind, to make the wind power generating set steady running.Variable paddle speed reducer requires high reliability: bearing capacity is big, 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 variable paddle speed reducer is leakage of oil.Background technique has two kinds:
(A) third-level planetary speed reducer: wherein Nanjing high gear company 200410064931 has obtained patent for invention.
(1) Nanjing high gear company " Yaw gearbox for wind power generator " (200410064931); (2) Chongqing gear-box company " wind generating variable-propeller reduction gear box " (200720188097); (3) Tianjin speed reducer company " the change oar gear reduction unit that is used for wind-power electricity generation " (200720125070); (4) Chongqing gear-box company " variable paddle speed reducer of band brake " (200820100450); (5) wind-powered electricity generation company " wind generating variable-propeller reduction gear box " (200920116858) advances in Hangzhou.
Third-level planetary speed reducer subject matter: (a) the slow speed turbine stage 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, many, the maintenance difficult of part in addition; (d) axial dimension long, heavy, cost an arm and a leg.
(B) bevel gear+secondary planet: the problem of company of ACE Semi (200910034525) is: (a) be still tertiary structure, bevel gear replacement planet is uneconomical, external form is big; The awl tooth subtracts i in the specification
1=5.0, " the Gear Transmission Design handbook is pointed out: in the multistage design, the bevel gear wheel diameter is excessive, manufacturing is difficult in order to avoid, and recommends i
1≤3..If i
1≈ 3, then second level i
2≈ 8.5, and speed ratio is obviously excessive; Is (b) the end face seal oil sealing assorted petty in said " support and oil sealing base mating face are provided with the end face seal oil sealing "? Mechanical seal? In this way, great machinery oil sealing price is very high so; It is the skeleton rubber oil sealing? In this way, its leakproof oiliness can be relatively poor.
[summary of the invention] the object of the invention be to provide a kind of bigger than planet bearing capacity, output shaft is oil-proof, axial dimension is short, the wind power generation three-piece cycloidal variable propeller reducer of in light weight, easy to maintenance and low cost of manufacture.
The three pieces type transmission: 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 in theory increases by 50%; (2) improved rotary arm bearing; (3) pin tooth and pin stress equalization.
The NGW planet that three-disk cycloid compares: (a) the single-stage reduction speed ratio is much bigger; (b) the cycloid wheel flexural strength is high, and multiple tooth engagement driving is steady, and bearing capacity is high; (d) manufacture cost half the less than the NGW planet.Shortcoming: (a) mechanical efficiency of cycloid transmission is lower than the NGW Gear Planet Transmission slightly, but for small-power, this is a minor issue; (b) freely supported structure gear pin flexural strength is lower.
[technological scheme] the present invention adopts one-level quasi-planet+one-level gerotor structure, and its two big technological scheme is following:
(A) improve the cycloid impact resistance: (a) adopt and partly bury toothing, make gear pin have very high counter-bending ability; (b) with in the silk thread cutting process machined needles alligator hole of being careful, make 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;
(B) effectively prevent leakage of oil: device Che Shi seal ring on the output shaft; Seal ring is made up of O type circle and thin lips and teeth RunddichtringO, have elastic compensating function, long lifetime, the low friction automatically of wearing and tearing backs, do not have leak and excellent specific property such as anti--55 ℃ of low temperature and extensively Ying Yu in space flight, field of petrochemical industry (see into big elder generation " mechanical design handbook " volume 2 for details and seal relevant paper) with Che Shi.
[beneficial effect] control background technology, particularly (200410064931) of patented invention, its novelty, creativeness and practicability are embodied in: (a) double reduction, compact structure, easy to maintenance, axial dimension short; (2) cycloidal gear teeth and partly bury the tooth needle pin can broken teeth, thereby have the Gear Planet Transmission bearing capacity of three planet wheels big than only; (b) price of existing cycloidal reducer half the less than planetary reducer, thereby low cost of manufacture 40-55%; (c) output shaft leakproof oil seal long service life.
