Description
Technical field
The present invention relates to large gear speed regulator technical field, a kind of large planetary is differential-the cycloid speed regulator.
Background technique
(1) " planetary-gear speed reducer or the speed regulator of employing mechanical core body " 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 efficient of main power drive is low, only is 85-90% (seeing " mechanical design handbook " Cheng Daxian volume 4.16-125 page); (2) complex structure, the high 35-55% of cost ratio NGW planet;
(3) to reach greatly the lightweight degree low for high pulling torque type volume.
Summary of the invention
The object of the invention provides that a kind of efficient is high, low cost of manufacture, high lightweight large planetary are differential-the cycloid speed regulator, in order to replace the large-scale planetary-gear speed reducer of lising in country " 12 ", replace large-scale star-wheel speed regulator.
The technological scheme technological scheme is mainly the restraining factors for the cycloid bearing capacity:
(1) cycloid wheel pin-and-hole grinding: Tianjin speed reducer factory initiates super sized type horizontal inner hole grinding machine, and the eccentric turning radius 594 (mm) is used for grinding X12 type cycloid wheel pin-and-hole." mechanical design handbook " middle 930 pages is loaded with larger four kinds of type: Dz=750,850,1000 and 1200, and this just requires the eccentric turning radius of super sized type horizontal inner hole grinding machine is 675-1000.Calculating shows, if when Rz=600, b=70, Ymax=1.5 and employing were partly buried toothing, four wheels can transmit T
2=600kNm, bearing capacity is identical with the maximum type HJW80D of star-wheel.But be impossible with the integral body cycloid wheel of hardening, because can not make large so inner hole grinding machine;
(2) only have 4 cycloid wheel works done to be difficult to make large-scale, super sized type gear-box: when being increased to 8 or 12 by 4, moment of torsion will be up to 1200 or 1800kNm., thereby the essential cage type W output mechanism that adopts;
(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, thereby radial internal clearance is larger.720 pages of Liu Zejiu " rolling bearing application manual ": " 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) adopting 1-5 group, four every group wheels, every wheel is ironcasting and bearing steel cycloid wheel rim assembly structure, makes input shaft upper rotary quality be in quiet, dynamic equilibrium state on the one hand, and another aspect is simplified technique greatly, greatly improves bearing capacity;
(2) eliminate vibration: adopt two back-to-back combinations of single-row tapered roller bearing, radial internal clearance controls to and approaches zero;
(3) partly bury the tooth pin wheel housing and be installed on main engine body input end endoporus, adopt rigidity cage type pin axle type output mechanism: with uniform pin, output shaft disk and equal load plate are integrally togather, block bearing is placed in both sides, shorten axial dimension, when cycloid wheel increases to many groups by one group, owing to all carrying annulus between wheel and wheel, make pin all be in freely supported structure, thereby have enough large flexural strength;
(4) between bevel gear pair and differential component, planetary part is arranged, make the small-power speed-adjustable motor have enough large speed governing moment of torsion.
