The megawatt ten-shunt wind power generation speed increasing box has the following advantages that: (1) the weight is 35 to 45 percent lighter than that of the prior product, and the shape is reduced by 40 to 50 percent; (2) a single piece is light and is convenient to assemble, disassemble and maintain; and (3) a gear slotting machine and a gear grinding machine made in China can process 5 MW model gears, and thus the manufacturing cost is greatly reduced.
Description
[technical field]
The present invention relates to the wind power speed-increasing technical field, a kind of megawatt ten-shunt wind power generation speed increasing box.
[background technique]
Wind energy is a kind of inexhaustible, nexhaustible, non-pollution of renewable energy.Predict that to the year two thousand twenty wind-powered electricity generation will become the third-largest energy of China, so wind power speed-increasing gearbox is being contained the great market of hundreds of hundred million.Wind power speed-increasing gearbox is one of wind power generating set three big core technologies, and world's mainstream model is 1.5～2MW at present.Because wind power speed-increasing gearbox is, remote districts six seven ten meters high-altitudes abominable at environment, therefore speedup box is proposed harsh requirement: 20 years working life, bearing life 130000 hours is as far as possible little light as far as possible, easy for assembly, disassembly and maintenance.Large enterprise of a few family of China obtains following six patent rights in succession: (one) Nan Gaochi " speed-increasing gearbox of wind driven generator (0620068477) (be 0420080174 improvement); (2) heavy tooth " planet driving of parallel axes wind power generation gear case " (02222633); " Gear Planet Transmission wind power generation speed increasing box " (03237681); (3) Dongfan Steam Turbine Factory " gear-box of wind generating unit " (200610021443).Wherein: heavy tooth " Gear Planet Transmission wind power generation speed increasing box " comes down to three grades of dead axle speedups transmission (professor of University Of Chongqing, post doctorate once delivered research paper on journal), and all the other are planet and add the two-stage parallel axis structure.Obviously, the bearing capacity of foregoing invention innovation depends primarily on the input stage Gear Planet Transmission.The Gear Planet Transmission why bearing capacity key that is higher than the hard flank of tooth is three branches shunting (because having only three planet wheels).Foregoing invention has a common ground, all adopts the connection casing of ring gear as one of coupling, and purpose is to alleviate single-piece weight.The disadvantage of coupling is a bad mechanical strength, has increased machining error and alignment error, temperature contrast between each coupling in addition, and the distortion that stressed difference produced also is not quite similar.Owing to can't adopt oblique internal tooth+cementite fire+gear-grinding process as external major company, make our product that big gap be arranged with it.
[summary of the invention]
The object of the invention be to provide a kind of volume, weight all less than external product, needn't adopt the megawatt ten-shunt wind power speed-increasing gearbox of oblique internal tooth gear-grinding process, easy accessibility.The technical problem that must solve is the ten minutes stream that power is obtained for achieving the above object, because the many more bearing capacities of shunting are big more, volume is more little, weight is light more.
Technological scheme: the present invention proposes a kind of is that the fixed shaft type of framework is shunted speedup box more based on ordinary transmission theory, moving axis planetary structure, comprise support, input shaft, ring gear, frame, duplicate gear and central shaft tooth cover, it is characterized in that: uniform five duplicate gears on the frame that (1) and support connect, frame main body places the ring gear inner chamber; (2) duplicate gear connects driving gear by shaftgear and forms, wherein: between ring gear and the shaftgear two identical idle wheels are arranged, form two shuntings; And be five shuntings between driving gear and the central shaft tooth cover, so cover forms ten shuntings from ring gear to the central shaft tooth, export by third level output gear shaft speedup at last.
Beneficial effect of the present invention: (1) weight ratio existing product is light by 35～45%, reduced profile 40～50%; (2) single-piece is light, adorns, tears open easy to maintenance; (3) homemade gear shaping machine, gear grinding machine can be processed the gear of 5MW type, and reduce manufacture cost greatly.
