Description
Technical field
The present invention relates to large gear speed regulator technical field, a kind of large planetary is differential-cycloid speed regulator.
Background technique
(1) " planetary-gear speed reducer of employing mechanical core body or speed regulator " ZL200510098706.7: the single star-wheel of owner's power drive, speed-adjustable motor drive planet speed regulating through bevel gear pair; (2) " star-wheel speed regulator " ZL200510098385.0: the double planet of owner's power drive, speed-adjustable motor drive single star-wheel speed governing through bevel gear pair; (3) " planet speed regulator " 200710097638.1: the double planet of owner's power drive, speed-adjustable motor drive planet speed regulating through bevel gear pair.Main existing problems are:
(1) the single planetary-gear speed reducer involute less tooth difference efficiency of main power drive is low, is only 85-90% (rolling up 4.16-125 page see " mechanical design handbook " Cheng great Xian); (2) complex structure, cost ratio NGW planet height 35-55%;
(3) high pulling torque type volume is large and light weight degree is low.
Summary of the invention
The object of the invention provides that a kind of efficiency is high, low cost of manufacture, high lightweight large planetary are differential-cycloid speed regulator, in order to replace the large-scale planetary-gear speed reducer of lising in country " 12 ", replaces large-scale star-wheel speed regulator.
Technological scheme technological scheme is mainly for the restraining factors of cycloid bearing capacity:
(1) cycloid wheel pin-and-hole grinding: Tianjin speed reducer factory initiates super sized type horizontal inner hole grinding machine, the eccentric turning radius 594 (mm) is used for grinding X12 type cycloid wheel pin-and-hole.In " mechanical design handbook ", volume 930 pages is loaded with larger four kinds of type: Dz=750,850,1000 and 1200, and this just requires that the eccentric turning radius of super sized type horizontal inner hole grinding machine is 675-1000.Calculating shows, if Rz=600, b=70, Ymax=1.5 adopt when partly burying toothing, four wheels can transmit T
2=600kNm, bearing capacity is identical with star-wheel maximum type HJW80D.But be impossible by entirety cycloid wheel of hardening, because inner hole grinding machine large so can not be manufactured;
(2) 4 cycloid wheel works done are only had to be difficult to manufacture large-scale, super sized type gear-box: when being increased to 8 or 12 by 4, moment of torsion up to 1200 or 1800kNm., thus will must adopt cage type W output mechanism;
(3) vibration of large gearbox: producing the main factor of vibration is that prior art input shaft capacity eccentric bearing all adopts the in-built eccentric bushing of roller bearing, and thus radial internal clearance is larger.Liu Zejiu " rolling bearing application manual " 720 pages: " the actual middle (center) bearing radial internal clearance that uses will have influence on bearing load distribution, vibration, noise, friction torque and life-span.”
Technological scheme is as follows:
(1) adopt 1-5 group, often organize four wheels, every sheet wheel is ironcasting and bearing steel cycloid wheel rim assembly structure, make input shaft upper rotary quality be in quiet, dynamic equilibrium state on the one hand, another aspect Simplified flowsheet greatly, improves bearing capacity greatly;
(2) vibration is eliminated: adopt two back-to-back combinations of single-row tapered roller bearing, radial internal clearance controls to close to zero;
(3) partly bury tooth pin wheel housing and be installed on main engine body input end endoporus, adopt rigidity cage type pin axle type output mechanism: output shaft disk and equal load plate are integrally togather with uniform pin, block bearing is placed in both sides, shorten axial dimension, when cycloid wheel by one group increase to organize more time, owing to all carrying annulus between wheel and wheel, make pin all be in freely supported structure, thus there is enough large flexural strength;
(4) there is planetary part between bevel gear pair and differential component, make small-power speed-adjustable motor have enough large speed governing moment of torsion.
