Description
Technical field
The present invention relates to a kind of planetary pinion drive technology field, specifically, relate to the load balancing mechanism that planetary pinion is shunted transmission more.
Background technique
In the gear transmission technology field, planetary type gear transmission unit has characteristics such as speed ratio is big, volume is little, bearing capacity height, be used widely in essential industry departments such as wind-power electricity generation, metallurgy, building materials, wind-power electricity generation industry particularly, the main step-up gear of the whole world 80% wind power generating set all adopts the planetary pinion transmission.Along with the develop rapidly of wind generating technology in the world, the transmission power of planetary type gear transmission unit is increasing, and (having reached 8MW at present) not only reliability requirement is higher, but also wants cube littler, weight is lighter, to reduce high manufacturing, transportation, installation and maintenance expense.
For this reason, the technician during with interior wind power speed-increasing epicyclic gearbox, can also adopt 3 traditional shunting NGW type Gear Planet Transmission structures at design 2MW, and market also can be accepted; 2.5MW above wind-powered electricity generation gear-box then requires to add differential or shunt the Gear Planet Transmission design more with 3 shunting NWG Gear Planet Transmission.Facts have proved that at present it is not fine to reducing gear-box volume and weight effects that 3 shunting NWG Gear Planet Transmission add difference structure.And a large amount of above high-power wind turbine gear-boxes of 3MW many (4-8 planet wheel) shunting Gear Planet Transmission that adopt design more, make the weight and volume of gear-box that bigger reduction be arranged.
A key technology is exactly the equal carrier technology of planet wheel in the design of many shunting Gear Planet Transmission.The equal carrier technology of planet wheel generally has two kinds of settling modes: first kind is that for example machining accuracies such as planet carrier, planet wheel, ring gear, planet wheel spring bearing, planet carrier spring bearing and casing reach and all carry purpose by raising Gear Planet Transmission component.This mode implements very difficulty, and manufacture cost is also very high, generally is fit to middle low power and the not high Gear Planet Transmission of reliability; The second way is to utilize the resiliently deformable of for example flexible ring gear of flexible member, flexible planet bearing pin to reach all to carry purpose.Flexible ring gear implements also undesirable, and this wherein mainly contains three reasons: first effect of load balancing mechanism is bad; It two is that accuracy of manufacturing is difficult for reaching, the big more thin more difficult more controlled deformation of ring gear; Its three poor reliability.The load balancing mechanism of flexible planet bearing pin as the many shuntings of planet wheel, its effect is more much better than alternate manner.Its advantage: 1) flexibility is big, and uneven year COEFFICIENT K γ is little, and is not high to the required precision of other Gear Planet Transmission component; 2) facewidth engagement spot is good, and teeth directional need not revised, and has improved the gear pair bearing capacity; 3) realize a plurality of planet wheel shunting transmissions, can make the compact weight saving of gear box structure.4) reliability height, cost is lower, implements relatively easy.
Below known two kinds of flexible planet pin load balancing mechanisms (hereinafter to be referred as load balancing mechanism) are analyzed comparison in that conditions such as planet wheel boundary dimension, the thick b of planet carrier side plate, material, load Fc and load center span 1 are identical.The similar Chinese China Machine Press of Fig. 4, Fig. 5 second edition " gear handbook first volume 7-43 page or leaf: constitute with back-up ring 4b, annulus bearing 5b, cone spacer 6b, outer ring spacer 7b, planetary pinion 8b, selfaligning bearing 9b, ring nut 10b and axle sleeve 11b in 2006 by ring nut 1b, flexible pin shaft 2b, planet carrier 3b, hole.This mechanism's planet wheel is contained in the load balancing mechanism on the cantilever axle.After this load balancing mechanism is mixed corresponding rolling bearing 5b, 9b, flexible planet bearing pin appears because of radial dimension and arm of force size Lb restriction causes its insufficient strength, amount of deflection yb is excessive, overload capacity is poor, boundary dimension B is also big.Be suitable as the load balancing mechanism of configuration sliding bearing; The similar American TI MKEN of Fig. 6, Fig. 7 company planet wheel is contained in the load balancing mechanism on the cantilever axle, and nut 1c, flexible pin shaft 2c, planet carrier 3c, axle sleeve 4c, planetary pinion 5c, tapered roller 6c, end ring 7c constitute.The design of this load balancing mechanism is that tapered roller bearing and axle sleeve and planet wheel are made of one, and aims at the design of large-scale wind electricity step-up gear, can bear 2.5 times of overload loads, and compact structure is simple, and volume is also little.Not enough place is: accuracy of manufacturing is very high, generally needs two industries of gear and bearing to unite manufacturing; Amount of deflection is little, makes the required precision of correlated parts such as planetary pinion, planet carrier, ring gear, casing for example still higher again.
