Abstract

The utility model discloses a rear output bevel gear transmission mechanism of a tractor gearbox, comprising a rear-drive driving bevel gear shaft and a rear output gear shaft which is vertical to the rear-drive driving bevel gear shaft, wherein a shifting gear and a driving bevel gear are arranged on the rear-drive driving bevel gear shaft; a driven bevel gear which is meshed with the driving bevel gear is arranged on the rear output gear shaft; and the shifting gear is sheathed on the rear-drive driving bevel gear shaft through a spline. The rear output bevel gear transmission mechanism of the tractor gearbox is characterized in that the driving bevel gear and the rear-drive driving bevel gear shaft are made to be in an integral structure. Through the rear output bevel gear transmission mechanism, the rigidity requirement of transmission power is satisfied and a deceleration function is realized, so that small gearboxes arranged on rear output transmission assemblies of traditional tractors can be saved and the production cost is reduced.

Description

The back output awl tooth driving mechanism of gear box of tractor
Technical field
The utility model relates to the technical field of gear box of tractor, especially relates to the back output awl tooth driving mechanism of gear box of tractor.
Background technique
The back output awl tooth driving mechanism of tradition gear box of tractor generally be by rear-guard initiatively conical tooth shaft and perpendicular to rear-guard initiatively the conical tooth shaft back output gear shaft of arranging constitute, rear-guard initiatively is equipped with put into gear gear and drive bevel gear by spline housing on the conical tooth shaft, and the driven wheel of differential that is meshed with drive bevel gear is installed on the back output gear shaft.During work, after dialling the retaining device control shift gear and the gear engagement of putting into gear, rear-guard initiatively conical tooth shaft rotates thereupon, drive bevel gear on the rear-guard active conical tooth shaft is also rotated thereupon, and drive the driven wheel of differential that is engaged with, rotate thereby drive the back output gear shaft that is connected with the back axle haulage gear.Because traditional drive bevel gear is at rear-guard initiatively on the conical tooth shaft by spline package, its external diameter will make bigger, could satisfy the rigidity requirement, can cause the volume ratio of gearbox bigger like this, and it cooperates with driven wheel of differential and does not also have decelerating effect, only has the transferring power function, therefore, a little gearbox also need be set in the driving mechanism of back to slow down, thereby make cost of production higher, if in order to realize deceleration, it is smaller that it is made external diameter, reach the not rigidity requirement of transfer strength again.
The model utility content
Technical problem to be solved in the utility model provides a kind of back output awl tooth driving mechanism of gear box of tractor, makes it have deceleration again under the condition that satisfies the rigidity requirement.
The utility model solves the problems of the technologies described above with following technological scheme:
The back output awl tooth driving mechanism of the utility model gear box of tractor comprises rear-guard active conical tooth shaft and the back output gear shaft of arranging perpendicular to rear-guard active conical tooth shaft, rear-guard initiatively put into gear on the conical tooth shaft gear and drive bevel gear, the driven wheel of differential that is meshed with drive bevel gear is arranged on the back output gear shaft, put into gear gear by spline package at rear-guard initiatively on the conical tooth shaft, described drive bevel gear is made integrally formed overall structure with rear-guard active conical tooth shaft.
The back output awl tooth driving mechanism of the utility model gear box of tractor both can satisfy the rigidity requirement of transferring power, had deceleration again, was arranged on the little gearbox on the output drive assembly behind traditional tractor thereby can save, and had reduced cost of production.
Description of drawings
Fig. 1 is the structural representation of the back output awl tooth driving mechanism of the utility model gear box of tractor.
Among the figure: 1---gearbox casing
2---driven wheel of differential
3---the back output gear shaft
4---the gear of putting into gear
5---rear-guard is conical tooth shaft initiatively
6---drive bevel gear
Embodiment
The utility model will be further described below in conjunction with accompanying drawing:
Be installed in put into gear on the rear-guard active conical tooth shaft 5 on the gearbox casing 1 gear 4 and drive bevel gear 6, put into gear gear 4 by spline package at rear-guard initiatively on the conical tooth shaft 5, drive bevel gear 6 is made integrally formed structure with rear-guard active conical tooth shaft 5, i.e. drive bevel gear 6 and rear-guard active conical tooth shaft 5 forms the integral structure that can not completely separately separate with physical method; Back output gear shaft 3 one ends of arranging perpendicular to rear-guard active conical tooth shaft 5 have the driven wheel of differential 2 that is meshed with drive bevel gear 6, and the other end outputting power of back output gear shaft 3 drives other device.
Because the utility model is made integrally formed overall structure with drive bevel gear 6 and rear-guard active conical tooth shaft 5, make the external diameter of drive bevel gear 6 can make smaller, make it under the condition that satisfies the rigidity requirement, active coniskoid 6 can be dwindled and reduces the number of teeth, therefore, drive bevel gear 6 cooperates with driven wheel of differential 2 and just plays decelerating effect, thereby saves the reducing gear of back one-level, reduces production costs.
