Abstract
A four-gear type final transmission device for high-clearance tractor comprises a drive gear, a left intermediate gear and a right intermediate gear, a driven gear, a final transmission shell body, a drive wheel shaft, a side port cover, an inner end bearing and an outer end bearing. The drive gear is meshed with the left and right intermediate gears under the drive gear at the same time. The left and right intermediate gears are meshed with the driven gear under the intermediate gears at the same time. The drive wheel shaft is connected with the driven gear through spline, tapered roller bearings are mounted on both sides of the driven gear on the drive wheel shaft, the drive wheel shaft is supported on the final transmission shell body through the two tapered roller bearings, the side port cover is in screwed connection with the lateral side of the final transmission shell body. The four-gear type final transmission device is different from traditional three-gear type transmission device, power is input from the drive gear and is distributed to two intermediate gears, and then power is converged in the driven gear and is output by the drive shaft. As each intermediate gear only transfers 1/2 torque, the center distance of the final transmission device for high-clearance tractor is reduced due to the double-intermediate gear; the thickness and weight of gear are also reduced.
Description
(1) technical field
The utility model belongs to the trac. field, relates to the final driving device of a kind of four gear type high-arch tractors.
(2) background technology
At present, at home and abroad on the various model high-arch tractors of Sheng Chaning, final driving device all is with three gears (driving gear, an intermediate gear, a ring gear) raises the crack, ground, final driving device like this is difficult arrangement in trac. trailing wheel wheel rim space, and the wheel rim that has is the very close wheel rim in position of disc fixedly, causes drive wheel wheel rim rigidity to die down; The final driving device that has even be installed in outside the wheel rim influences trac. in the field intertillage operation and the management in crops later stage.
(3) summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, reliable operation, easy accessibility, the advanced in performance final driving device of four gear type high-arch tractors.
The technical solution of the utility model is: four gear type high-arch tractors mainly comprise with final driving device: driving gear 1, left intermediate gear 2, right intermediate gear 3, driven gear 4, final transmission housing 5, live axle 6, side flap 7, outer side bearing 8, interior side bearing 9.It is characterized in that: driving gear 1 is meshed with the left intermediate gear 2 and the right intermediate gear 3 of its underpart simultaneously.Left side intermediate gear 2 and right intermediate gear 3 are meshed with the driven gear 4 of its underpart simultaneously.Live axle 6 and driven gear 4 are connected by spline, driven gear 4 both sides on the live axle 6 are equipped with outer side bearing 8 and interior side bearing 9, live axle 6 is supported on the final transmission housing 5 by outer side bearing 8 and interior side bearing 9, and side flap 7 is screwed onto final transmission housing 5 sides.
Outer side bearing 8, interior side bearing 9 are circular cone roller bearing.
The utility model can reach following beneficial effect:
Four gear type high-arch tractors with final driving device owing to adopt a driving gear, two intermediate gears, a ring gear structure, different with three traditional gear types, power is after the driving gear input, be diverted on two intermediate gears, and then be pooled to ring gear and export by axle drive shaft.Because each intermediate gear only transmits 1/2 moment of torsion in theory, thus adopt two intermediate gears that high-arch tractor is reduced with the width between centers of final driving device, the width attenuate of gear, axial dimension shortens, and quality alleviates.
(4) description of drawings
Fig. 1 is the constructionals drawing of the utility model four gear type high-arch tractors with final driving device.
Fig. 2 is the A-A cutaway views of the utility model four gear type high-arch tractors with final driving device.
(5) specific embodiment
As shown in Figure 1 and Figure 2, four gear type high-arch tractors comprise with final driving device: driving gear 1, left intermediate gear 2, right intermediate gear 3, driven gear 4, final transmission housing 5, live axle 6, side flap 7, outer side bearing 8, interior side bearing 9 etc.Wherein, driving gear 1 is meshed with left intermediate gear 2 and right intermediate gear 3 simultaneously.Left side intermediate gear 2 and right intermediate gear 3 are meshed with driven gear 4 simultaneously.Live axle 6 and driven gear 4 are connected by spline, driven gear 4 both sides on the live axle 6 are equipped with outer side bearing 8 and interior side bearing 9, live axle 6 is supported on the final transmission housing 5 by outer side bearing 8 and interior side bearing 9, and side flap 7 is screwed onto final transmission housing 5 sides.Outer side bearing 8, interior side bearing 9 are circular cone roller bearing.
During work, power by driving gear 1 be delivered to two intermediate gears of its ingear 2,3 on, two intermediate gears 2,3 with transmission of power to its ingear driven gear 4 on, driven gear 4 is by giving trailing wheel with its spline bonded assembly live axle 6 with transmission of power.
