Abstract

The invention relates to a herringbone-tooth planet gearbox of a planet gear transmission device. The herringbone-tooth planet gearbox is characterized in that two inner gear rings are fixed on a box body of the planet gearbox; three adjusting pads are respectively arranged on three planet gear shafts; the planet gear shafts are arranged on a planet carrier; three planet gears are respectively arranged on the planet gear shafts through bearings; a center gear is arranged in the middle of the planet gearbox, wherein one end of the center gear is an input end; a gear sleeve is connected with the planet carrier, one end, which extends out of the planet gearbox, of the gear sleeve is an output end; the planet carrier is meshed with the gear sleeve 7 through crowned teeth; the three planet gears, the center gear and the two inner gear rings are herringbone gears; the three planet wheels are meshed with the center gear and the two inner gear rings. The herringbone-tooth planet gearbox has the advantages that under the same volume, the bearing capacity of the gearbox is improved, uniform load is realized, the curved safety coefficient of the gears can be increased by 30 percent, and the contact safety coefficient is increased by 20 percent.

Description

Double helical tooth planetary gear-box
Technical field
The present invention relates to planetary type gear transmission unit.
Background technique
Gear Planet Transmission is a kind of gear transmission with rotation axis, can be used for deceleration, speedup and differential motion.Planetary Gear Transmission compare with general column gear transmission have lightweight, volume is little, velocity ratio is large, efficiency advantages of higher.Shortcoming is complex structure, and required precision is higher.For the difficulty that reduces design, manufactures and assemble, be all generally to adopt straight-tooth driving mechanism.Straight-tooth transmission can not produce axial force, but its contact ratio and overlap ratio is low, and transmission stability is poor.For meeting torque transmission capacity, the volume of gear-box is often larger.If adopt helical teeth driving mechanism, although it is low to solve contact ratio and overlap ratio, the stationarity of transmission also improves.But helical teeth transmission meeting produces very large axial force, makes the axially locating of driving mechanism very difficult.
Summary of the invention
The invention reside in a kind of double helical tooth planetary gear-box is provided, it is a kind of with the gear-driven epicyclic gearbox of herringbone.
The present invention realizes with following technological scheme:
The present invention includes the central gear in casing and casing, 3 planet wheels, 3 planet wheel shafts, adjust packing ring for 3, two ring gears, planet carrier, tooth cover, two ring gears are fixed on casing, 3 planet wheel shafts are connected on planet carrier, adjust packing ring respectively on 3 planet wheel shafts for 3, 3 planet wheels are connected on 3 planet wheel shafts by 3 bearings respectively, one end of central gear is input end, tooth is enclosed within on epicyclic gearbox and stretches out epicyclic gearbox is outward output terminal, planet carrier is connected by crowned teeth with tooth cover, 3 planet wheels, central gear, two ring gears are herringbone gear, spacer on planet wheel shaft is adjusted the axial position of planet wheel, make impartial 3 planet wheels of 3 planet wheel stands under load and central gear, two ring gear engagements.
 
Advantage of the present invention is:
1, the present invention is simple in structure, under equal volume, can improve the bearing capacity of gear-box, due to adjustment packing ring being housed on planet wheel shaft, being convenient to realize and all carrying.
2, planet wheel of the present invention, central gear, ring gear are herringbone tooth structure, same load with under coefficient of facewidth prerequisite, compare with monocline tooth, the crooked safety coefficient of gear has improved 30%, touch-safe coefficient has improved 20%.
3, the planet carrier that the present invention is unsteady has adopted crowned teeth to be connected with output gear cover, can compensate the angle of deviation and position.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural drawing of epicyclic gearbox combination.
Embodiment
In Fig. 1-2: the casing 10 of epicyclic gearbox is fixed in frame, two ring gears 4 and 9 are fixed on casing 10, 3 planet wheel shafts 2 are connected on planet carrier 8, 3 spacers 11 are contained in respectively on 3 planet wheel shafts 2, 3 planet wheels 3 are contained on 3 planet wheel shafts 2 by 3 rolling bearings 6 respectively, spacer 11 can in when assembling, according to planet wheel 3, the actual loading situation during in work be accurately adjusted planet wheel 3 axial position reach the uniform object of 3 planet wheels, 3 load, central gear 1 is at the middle part of epicyclic gearbox 12, one end of central gear 1 is input end, tooth cover 7 output terminals at epicyclic gearbox 12 also stretch out outside epicyclic gearbox 12, central gear 1 and planet wheel 3, planet carrier 8 floating connections, planet carrier 8 meshes by crowned teeth with tooth cover 7.
3 planet wheels 3, central gear 1, two ring gears 4 and 9 be herringbone gear and 3 planet wheels and two ring gears 4 and 9 and central gear 1 by herringbone tooth, mesh simultaneously.During work, power is inputted by input flange 14, parallel stage gear transmission by planet case combination 13 is sent to power the central gear 1 of epicyclic gearbox 12, then by after the herringbone gear transmission in epicyclic gearbox 12, by tooth cover 7, is transmitted power to outside epicyclic gearbox 12.
