Abstract
A tractor clutch main driving shaft assembly comprises a main driving shaft, a shaft sleeve, an annular boss, a gear, a spacer and a spline. The annular boss is manufactured around the shaft sleeve, and the shaft sleeve and the annular boss are integrated. The gear is arranged on the annular boss in a sleeved mode, the spline is installed on the front end of the shaft sleeve, and the spacer is installed on the junction of the spline and the annular boss. The length of the shaft sleeve is 450+/-1 millimeters, the distance between the back end face of the annular boss and the front end face of the shaft sleeve is 173.5+/-0.5 millimeters, and the effective length of the spline is 90+/-0.5 millimeters. By means of testing, in tractors with the same power, compared with assemblies in the prior art, the tractor clutch main driving shaft assembly has the advantages that due to the fact that the area of the annular boss on the shaft sleeve is increased, strength of the shaft sleeve is increased, heat-sinking capability of a friction clutch can be significantly improved, and friction torque is increased, so service life of the assembly is prolonged, and usage cost is reduced.
Description
Technical field
The utility model belongs to the tractor field, relates to a kind of tractor clutch, relates in particular to a kind of tractor clutch main drive shaft assembly parts.
Background technique
Clutches for Tractor is installed on the motor and the engine flywheel between the gearbox of tractor, and its function is: cut off power, transferring power during joint during clutch separation.At present, the clutch that domestic tractor is commonly used is commonly the double-action friction clutcch, and its clutch main drive shaft assembly parts is mostly for split designs, its torsional strength a little less than, the moment of torsion transmission effect is relatively poor.Therefore, if clutch main drive shaft assembly parts is improved on the original structure basis, its torsional strength is increased, friction torque increases thereupon, will improve the transmission efficiency of tractor, can receive user's welcome undoubtedly.
The model utility content
The purpose of the utility model is to provide a kind of simple in structure, easy to make, cost is lower, functional reliability is good tractor clutch main drive shaft assembly parts.
The technological scheme of the utility model is: tractor clutch main drive shaft assembly parts comprises: main drive shaft, axle sleeve, annular boss, gear, spacer, spline; Process annular boss around axle sleeve, it is become one, set gear on the annular boss, the axle sleeve front end is installed spline, and spline and annular boss intersection are equipped with spacer.
Sleeve length is 450 ± 1mm, and annular boss ear end face and axle sleeve front-end face distance are 173.5 ± 0.5mm, and the spline effective length is 90 ± 0.5mm.
The utility model adopts the good effect that produces after the technique scheme to be: through overtesting; On tractor, use this assembly parts to compare, owing on axle sleeve, strengthened the area of annular boss with assembly parts of the prior art with constant power; Axle sleeve intensity is increased; Can obviously improve the heat dissipation potential of friction clutcch and increase friction torque, thereby prolong the working life of assembly parts, also reduce user cost.
Description of drawings
Fig. 1 is the structural representation of the utility model tractor clutch main drive shaft assembly parts;
Fig. 2 is the structural representation of tractor clutch main drive shaft assembly parts of the prior art.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.As shown in Figure 1, tractor clutch main drive shaft assembly parts comprises: main drive shaft 1, axle sleeve 2, annular boss 3, gear 4, spacer 5, spline 6; On axle sleeve 2, process annular boss 3, annular boss 3 is become one around axle sleeve 2, set gear 4 on annular boss 3, and axle sleeve 2 front ends (Fig. 1 right side) are installed spline 6, and spline 6 is equipped with spacer 5 with annular boss 3 intersections.
The length L 1 of axle sleeve 2 is 450 ± 1mm, and annular boss 3 ear end faces and axle sleeve 2 front-end face distance L 2 are 173.5 ± 0.5mm, and spline 6 effective length L3 are 90 ± 0.5mm.
Through comparative trial; On tractor, use this assembly parts to compare, owing on axle sleeve 2, strengthened the area of annular boss 3 with assembly parts of the prior art with constant power; The intensity of axle sleeve 2 is increased; Can obviously improve the heat dissipation potential of friction clutcch and increase friction torque, thereby prolong the working life of assembly parts, also reduce making and user cost.
