Technical field
The utility model belongs to gear transmission technology field, is specifically related to a kind of engaging sleeve toothholder.
Background technique
Existing engaging sleeve toothholder is provided with internal spline and external splines, although can meet usage requirement to a certain extent, still exists not enough:
1) lubrication between internal spline and splined shaft is insufficient, causes excessive wear between internal spline and splined shaft, have impact on the working life of engaging sleeve toothholder and splined shaft;
2) external splines is common spline structure, after it engages with spline structure engage a gears such as engaging sleeves, there is problem easily out of supply.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of engaging sleeve toothholder, can not only avoid out of supply, and can improve lubrication effect.
For achieving the above object, the utility model provides following technological scheme:
A kind of engaging sleeve toothholder, comprise toothholder body, the center of described toothholder body is provided with central through bore, internal spline is provided with in described central through bore, the periphery wall of described toothholder body is provided with smooth section and engaged section, the external diameter of described engaged section is greater than the external diameter of described smooth section, and described engaged section is provided with external splines, described smooth section is provided with the oilhole leading to described central through bore, the middle part of all spline tooths of described external splines is equipped with the section of thickening, described in the width of the section of thickening be greater than the width of its place spline tooth.
Further, the section of thickening described in is arranged axisymmetricly relative to the symmetry plane of its place spline tooth.
Further, the thickness difference between the described spline tooth thickening Duan Yuqi place described in is 0.2-0.4mm.
Further, described in, the length of the section of thickening is 2.5-4mm.
Further, described oilhole annular is uniform is set at least one.
Further, be provided with annular oil groove in described central through bore, described annular oil groove communicates with described oilhole.
The beneficial effects of the utility model are:
Engaging sleeve toothholder of the present utility model, leads to central through bore by arranging oilhole in smooth section, can guarantee that lubricant oil fully enters in central through bore, makes the lubrication between internal spline and splined shaft more abundant; By arranging the section of thickening in the middle part of the spline tooth of external splines, after external splines engages with other spline structure engage a gears, due to the existence of this section of thickening, can prevent external splines and other spline structures from departing from, external splines namely can be prevented out of supply.
Accompanying drawing explanation
In order to make the purpose of this utility model, technological scheme and beneficial effect clearly, the utility model provides following accompanying drawing to be described:
