Description

Pulley shaft on grass-mowing machine
Technical field
The utility model relates to grass-mowing machine device technique field, is a kind of Pulley shaft on grass-mowing machine specifically.
Background technique
Pulley shaft is the important spare part on grass-mowing machine, but existing Pulley shaft adds the bad control of spline length dimension in man-hour, not easily processes, and error is large, and impact is installed and used.
Model utility content
The purpose of this utility model provides a kind of size easily to control, and easily processes, and can coordinate smoothly, carry out the Pulley shaft installed and use smoothly with other parts.
For achieving the above object, the technical solution of the utility model is: the Pulley shaft on grass-mowing machine, comprise spline processing district, step positioning area, annulus, spline processing district, step positioning area, annulus is the structure that Pulley shaft mills out, with Pulley shaft one, the annulus that diameter is greater than Pulley shaft diameter is provided with in the neutral position of Pulley shaft, two ends are respectively arranged with wheel shaft I and spline processing district, outer end, described spline processing district is also provided with wheel shaft II, the inner, described spline processing district is provided with diameter and is greater than spline processing district diameter, and be less than the step positioning area of Pulley shaft diameter, described wheel shaft II diameter is less than spline processing district diameter, described spline processing district, the sectional shape of step positioning area is identical with the sectional shape of Pulley shaft.
Owing to adopting technique scheme, add step positioning area, not only spline length dimension easily controls, and easily processes, and can also coordinate with other parts smoothly, carries out smoothly installing and using, adds convenience of the present utility model.
Accompanying drawing explanation
Now by reference to the accompanying drawings the utility model is described further.
Fig. 1 is structural representation of the present utility model.
In figure: 1, spline processing district, 2, step positioning area, 3, annulus, 4, wheel shaft I, 5, wheel shaft II.
Embodiment
As shown in Figure 1, Pulley shaft on grass-mowing machine, comprise spline processing district 1, step positioning area 2, annulus 3, spline processing district 1, step positioning area 2, the structure that annulus 3 mills out for Pulley shaft, with Pulley shaft one, the annulus 3 that diameter is greater than Pulley shaft diameter is provided with in the neutral position of Pulley shaft, two ends are respectively arranged with wheel shaft I 4 and spline processing district 1, outer end, spline processing district 1 is also provided with wheel shaft II 5, the inner, spline processing district 1 is provided with diameter and is greater than spline processing district 1 diameter, and be less than the step positioning area 2 of Pulley shaft diameter, wheel shaft II 3 diameter is less than spline processing district 1 diameter, spline processing district 1, the sectional shape of step positioning area 2 is identical with the sectional shape of Pulley shaft.
