Abstract
The utility model belongs to the technical field of gearboxes of wheel-type tractors, and relates to a connection structure of a gearbox input shaft of a wheel-type tractor. The structure comprises the hollow input shaft, a I-gear driving gear is integrally manufactured on the middle portion of the input shaft, taper roller bearings are arranged on bearing installation positions on the input shaft on the two sides of the I-gear driving gear, and the input shaft is supported on a gearbox shell through the taper roller bearings. The structure is characterized in that the I-gear driving gear and the input shaft are manufactured to be of an integral structure, so that the strength of the I-gear driving gear is high, the phenomenon that gears are damaged due to overload is greatly reduced, ball bearings are replaced by the taper roller bearings to support the input shaft, supporting rigidity of the input shaft is large, transmission is stable, meshing load of gears in meshed transmission is uniform in the gear length direction, noise is low, the service life of a gear pair is long, and the connection structure is suitable for the gearbox input shaft of the wheel-type tractor.
Description
Technical field
The utility model belongs to wheeled tractor gearbox technical field, refers in particular to a kind of linkage structure of wheeled tractor gearbox input shaft.
Background technique
Referring to Fig. 1: at present, on the input shaft 5 of conventional wheeled tractor gearbox with involute splines, on involute splines, be set with the I shelves driving gear 4 with internal spline, on bearing installation position 3 on the input shaft 5 of I shelves driving gear 4 both sides, be separately installed with ball bearing 2, input shaft 5 is supported on the housing 1 of gearbox by ball bearing 2, is set with power take-off drive shaft 6 in input shaft 5; Its deficiency is: the one, due to the tooth root of this I shelves driving gear 4 to internal spline greatly through distance little (4mm), make the flexural strength deficiency of gear, the phenomenon that while often appearing at overburdening, tooth portion damages occurs; The 2nd, because the gear of other gear is because rotating speed is higher, in the time of engagement, because the support stiffness that input shaft supports by ball bearing 2 is poor, make the tooth length direction engagement load inequality of the gear of intermeshing transmission, cause noise larger, the working life of gear is little.
Summary of the invention
The purpose of this utility model is to provide a kind of linkage structure of wheeled tractor gearbox input shaft.
The purpose of this utility model is achieved in that
The linkage structure of wheeled tractor gearbox input shaft, include hollow input shaft, the integral middle of described input shaft is manufactured with I shelves driving gear, on the bearing installation position arranging on the input shaft of I shelves driving gear both sides, be separately installed with tapered roller bearing, input shaft is supported on gear box casing by tapered roller bearing.
Above-mentioned I shelves driving gear is involute gear.
In above-mentioned input shaft, be set with power take-off drive shaft.
The utility model compared to existing technology outstanding and useful technique effect is:
1, I shelves driving gear of the present utility model and input shaft manufacture integral structure, make the intensity of I shelves driving gear high, and the phenomenon that while having greatly reduced overburdening, tooth portion damages occurs.
2, the utility model arranges on the installation position of ball bearing tapered roller bearing is installed on input shaft, to substitute ball bearing, make the support stiffness of input shaft large, the slow-roll stabilization of input shaft, the engagement load of the tooth length direction of the gear of intermeshing transmission is even, noise is little, the long service life of gear pair.
3, the linkage structure of the input shaft that is applicable to wheeled tractor gearbox of the present utility model.
Brief description of the drawings
Fig. 1 is that prior art is arranged on the structure sectional view in wheeled tractor gearbox.
Fig. 2 is that the utility model is arranged on the structure sectional view in wheeled tractor gearbox.
Embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 2:
The linkage structure of wheeled tractor gearbox input shaft, include hollow input shaft 14, the integral middle of described input shaft 14 is manufactured with I shelves driving gear 13, on the bearing installation position 12 arranging on the input shaft 14 of I shelves driving gear 13 both sides, be separately installed with tapered roller bearing 11, input shaft 14 is supported on gear box casing 10 by tapered roller bearing 11.
Above-mentioned I shelves driving gear 13 is involute gear.
In above-mentioned input shaft 14, be set with power take-off drive shaft 15.
Above-described embodiment is only preferred embodiment of the present utility model, not limits according to this protection domain of the present utility model, therefore: all equivalences of doing according to structure of the present utility model, shape, principle change, within all should being covered by protection domain of the present utility model.
