Description
Technical field
The utility model belongs to machinery and manufactures field, is specifically related to a kind of herringbone gear planetary reducer.
Background technique
Planetary reducer is the effect of playing coupling rotating speed and transmitting torque between prime mover and working machine, the winding number of prime mover is decelerated to desired winding number, and obtain the mechanism of larger torque.
Traditional scheme plane table thermoconductivity meter volume and weight is larger, main cause is that planet part planet carrier needs spring bearing, cause planet carrier excessive, need to adopt 5 planet wheels to adopt and meet requirement of strength, major defect is that volume and weight is excessive, approximately four tons of weights, beam overall 1104mm, be arranged on heavy off-road vehicle, weight and volume limits to some extent.Technical solutions of the utility model are more lightweight than conventional solution, volume is little, utilize herringbone gear technology, use power dividing, by several planet wheels, share load, and engagement in rationally utilizing, and adopt rational load balancing mechanism, make Planetary Gear Transmission there is the features such as quality is light, volume is little.
Model utility content
The utility model aims to provide a kind of herringbone gear planetary reducer, in order to solve prior art, adopts straight-tooth, and planet carrier needs bearings quality weight, bulky defect conventionally.
The technical solution of the utility model realizes by the following method:
A kind of herringbone gear planetary reducer, comprise input flange 1, input shaft 2, input herringbone tooth 3, output herringbone tooth 4, casing 5, planet carrier 6, sun gear 7, planet axis 8, planet wheel 9, ring gear 10, output spline 11 and spline flange 12, wherein input flange 1 rotates by spline band driven input shaft 2, bearing and input herringbone tooth 3 are housed on input shaft 2, input herringbone tooth 3 is by external tooth and 4 engagements of output herringbone tooth, bearing is equipped with on the wheel hub both sides of output herringbone tooth 4, in the wheel hub of output herringbone tooth 4, be designed with spline, by splined, drive sun gear 7, sun gear 7 external tooth engagement planet wheels 9, planet wheel 9 is meshed with ring gear 10 and is connected by internal tooth, star-wheel 9 is arranged in planet axis 8 by two aligning roller bearings, ring gear 10 is fixing, described planet axis 8 is fixed on planet carrier 6, described planet carrier 6 is by inside and outside splined output spline 11, described output spline 11 connects spline flange 12.Sun gear, planet wheel, ring gear are herringbone tooth structure.
Further, described sun gear 6, planet wheel 9 and ring gear 10 are all herringbone tooths.
Further, described planet wheel 9 comprises three herringbone gears.
Further, described bearing adopts NU structure float support, guarantees its Meshing engagement energy.
Further, described input shaft rotation direction is that described output shaft rotation direction is counterclockwise clockwise.
Further, described sun gear and planet carrier float simultaneously, make it all carry transmission.
The beneficial effects of the utility model: traditional planet carrier for planetary reduction gear needs bearings conventionally, gear adopts straight-tooth, take up room relatively large, and heavier, be arranged on heavy off-road vehicle, weight and volume limits to some extent, this technology provides the design of gear application by people, do not have axial force to produce, planet carrier bearings useless, from volume and weight, more general planetary reducer has more advantage.
Accompanying drawing explanation
Accompanying drawing is the structural representation of the utility model herringbone gear planetary reducer;
Each parts mark in accompanying drawing is as follows: input flange 1, input shaft 2, input herringbone tooth 3, output herringbone tooth 4, casing 5, planet carrier 6, sun gear 7, planet axis 8, planet wheel 9, ring gear 10, output spline 11, spline flange 12.
Embodiment
Below principle of the present utility model and feature are described, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, a kind of herringbone gear planetary reducer, comprise input flange 1, input shaft 2, input herringbone tooth 3, output herringbone tooth 4, casing 5, planet carrier 6, sun gear 7, planet axis 8, planet wheel 9, ring gear 10, output spline 11 and spline flange 12, wherein input flange 1 rotates by spline band driven input shaft 2, bearing and input herringbone tooth 3 are housed on input shaft 2, input herringbone tooth 3 is meshed and is driven output herringbone tooth 4 by external tooth, bearing is equipped with on the wheel hub both sides of output herringbone tooth 4, bearing type is NU structure, and output herringbone tooth floats.In the wheel hub of output herringbone tooth 4, be designed with spline, by splined, drive sun gear (herringbone tooth) 7, sun gear is crossed external tooth engagement and is driven three planet wheels 9, and three planet wheels 9 mesh by internal tooth and connect with ring gear 10, and ring gear 10 is fixed.Three planet wheels 9 are arranged in planet axis 8 by two aligning roller bearings, and planet axis 8 is fixed on planet carrier 6, and row frame frame 6, by inside and outside splined output spline 11, connects output spline 11 and connects spline flange 12, and power is finally by 12 outputs of spline flange.Sun gear 7, planet wheel 9, ring gear 10 are herringbone tooth structure.Planet carrier and sun gear float, and owing to being herringbone tooth transmission, there is no axial force, and planet carrier both sides do not have bearing to fix, and have alleviated weight of equipment.
After power is inputted by input flange, through herringbone tooth ordinary transmission, enter Planetary Gear Transmission, sun gear adopts herringbone gear, by the power dividing of three herringbone gear planetary wheels, with the engagement of herringbone tooth ring gear, transmitting torque adds frame to planet simultaneously, drives inner spline housing output.
The all gears of planetary reducer all adopt low-carbon alloy steel carburizing and quenching, and herringbone tooth transmission does not have axial force to produce, and planet carrier bearings useless, can effectively reduce volume and weight.
This plane table thermoconductivity meter is to be the input of 3000hp power and reducing gear, work required power by motor, torque converter after, by transmission shaft, be input to the spline flange 12 on plane table thermoconductivity meter, deceleration rear driving working machine bent axle, the to-and-fro motion of bent axle drivening rod.
The concrete technical requirements of plane table thermoconductivity meter is as follows:
A. maximum power input rating: 3000hp;
B. reduction speed ratio: 7.84:1;
C. maximum input torque: 30000N.m;
D. the highest input speed: 1950rpm;
