Abstract
The utility model provides a final drive gear of an enclosed double-bracing planetary gear used in a drive axle. The final drive gear comprises a planet carrier, a gear ring, a middle support frame, double planetary gears, roller pins, a separation blade, a planet wheel axle, a sun wheel axle, a slide bearing, a steering knuckle, and the like, wherein, the slide bearing is mounted in the steeringknuckle in a pressed manner; the sun wheel axle is mounted in the slide bearing; four double planetary gears mounted with double-row roller pins are mounted on the planet wheel axle sequentially; theseparation blade is embedded on the other sides of the roller pins; four holes of the middle support frame are mounted in the planet wheel axles in an aligned manner; the end surface of the middle support frame is tightly clung to the separation blade; and the middle support frame is fixedly connected with the planet carrier through a screw. By adopting the drive gear, the utility model can improve the strength of a gear, increase the transmission ratio of a planetary gear train so as to meet the requirements of high torque output of a complete machine, meanwhile realize double bracing of thedouble planetary gear, ensure that the double planetary gears and the sun wheel axle as well as the gear ring are reliably meshed with each other, and have reasonable and compact structure, and favorable effect.
Description
(1) technical field:
The utility model belongs to Vehicle Engineering vehicle bridge field, relates to a kind of drive axle enclosed double-support planetary-gear final drive gear.
(2) background technology:
At present, in the axle components of domestic trac. and construction machinery and equipment, NGW type epicyclic transmission mechanism is adopted in the final transmission of drive axle, particularly closed planet carrier structure is because of its compact conformation, processing technology is good, grade easy to assembly has obtained using widely, and its structure reinstalls the transmitting ratio that the engagement of planetary wheel and sun wheel and internally toothed annulus realizes machine requirement for to be pressed into compensating-gear shaft in the osed top pinion carrier.Because the final drive mechanism of drive axle is subjected to the restriction of tyre rim diameter and spoke plate seam, make osed top pinion carrier inner chamber radial dimension add to the difficulties, cantilevered its rigidity of support of planetary wheel supporting construction also restricts the increase of axial dimension simultaneously, can't increase gear and improve the strength of gear teeth to satisfy the requirement of complete machine in limited space.Therefore, need a kind of new structure to address this problem, do not increasing the main gear ratio, do not increase pinion carrier inner chamber radial dimension, do not weaken under the condition of transmission strength and stiffness of gear, the reduction ratio that improves the final transmission of drive axle is in order to realize the requirement of complete machine high pulling torque output.
(3) utility model content:
It is a kind of easy to assembly that the purpose of this utility model is to provide, compact conformation, the drive axle of good reliability enclosed double-support planetary-gear final drive gear.
The technical solution of the utility model is: drive axle comprises with the enclosed double-support planetary-gear final drive gear: pinion carrier 1, gear ring 2, intermediate support beam 3, compound planet gear 4, needle roller 5, catch 6, planet wheel spindle 7, sun wheel shaft 8, spacing shim 9, plain bearing 10, steering swivel 11, screw 12, plain bearing 10 is press-fited in steering swivel 11, sun wheel shaft 8 is packed in the plain bearing 10, spacing shim 9 and four planet wheel spindles 7 are pressed in the pinion carrier 1, reinstall catch 6, four compound planet gears 4 that double needle roller 5 is housed are packed on the planet wheel spindle 7 successively, then catch 6 is inserted in the opposite side of needle roller 5, four Kong Yusi planet wheel spindles 7 of intermediate support beam 3 are aligned pack into and its end face and catch 6 are adjacent to, fixed by screw 12 and pinion carrier 1.
The beneficial effects of the utility model are: adopt utilization NW type epicyclic transmission mechanism in the osed top pinion carrier, can improve the intensity of gear, the transmitting ratio that increases planet circular system is to satisfy the requirement of complete machine high pulling torque output, simultaneously intermediate support beam is adopted seam location and fixed by screw and pinion carrier, realize the compound planet gear double bracing, guarantee the positive engagement of compound planet gear and sun wheel shaft and gear ring, improve rigidity of support and satisfied matching requirements again, the structure of while pinion carrier and intermediate support beam split, reduced the casting difficulty, improved the processing technology type, compactness rational in infrastructure, respond well.
(4) description of drawings:
Fig. 1 is the structural representation of the utility model drive axle with the enclosed double-support planetary-gear final drive gear.
(5) specific embodiment:
As shown in Figure 1, drive axle comprises with the enclosed double-support planetary-gear final drive gear: pinion carrier 1, gear ring 2, intermediate support beam 3, compound planet gear 4, needle roller 5, catch 6, planet wheel spindle 7, sun wheel shaft 8, spacing shim 9, plain bearing 10, steering swivel 11, screw 12.
Earlier plain bearing 10 is press-fited in steering swivel 11, sun wheel shaft 8 changes in the plain bearing 10, again spacing shim 9 and four planet wheel spindles 7 are pressed in the pinion carrier 1, reinstall catch 6, four compound planet gears 4 that double needle roller 5 is housed are packed on the planet wheel spindle 7 successively, then catch 6 is inserted in the opposite side of needle roller 5, four Kong Yusi planet wheel spindles 7 of intermediate support beam 3 is aligned pack into and its end face and catch 6 are adjacent to, fixed by screw 12 and pinion carrier 1.
Under the situation of same rim diameter, the requirement of realization big speed ratio guarantees the intensity and the rigidity of gear simultaneously again in the osed top pinion carrier, thereby employing NW planetary gear speed reducing mechanism, power imports into from sun wheel shaft, satisfies the requirement of big speed ratio by another group and the gear ring engagement of one group of gear driven compound planet gear of compound planet gear.
Realize its secure support owing to intermediate support beam 3 could be packed into after the special structure of compound planet gear must be packed it into, thereby adopt split type structure, and processing seam and pinion carrier centering, vacant position at four satellite gear axis holes makes its reliable connection with eight screws, guarantee that it does as a whole requirement of bearing high pulling torque, also realized the double bracing of compound planet gear, adopt this fabricated structure, change cantilever structure into the freely-supported girder structure, the influence of the capsizing moment when making it not be subjected to gear mesh improves its rigidity of support to satisfy the demand of complete machine.
