Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of output shaft of gear-box gear, effectively can improve lubrication effect, improves working life.
For achieving the above object, the utility model provides following technological scheme:
A kind of output shaft of gear-box gear, comprise gear, the center of described gear is provided with central through bore, and one end of described gear is provided with driving gear, and the other end is provided with spline; One end end face that described gear is provided with spline is provided with radial end face oil groove, one end end face that gear is provided with driving gear is provided with annular annular oil groove, is provided with the oblique oil groove passed through for lubricant oil between described annular oil groove and described central through bore.
Further, described oblique oil groove ring uniform setting ringwise.
Further, described spline is involute splines, and described driving gear is cylindrical gears.
Further, all spline tooths of described spline are provided with away from one end of described driving gear the arc envelope face formed by circular arc chamfering.
Further, the external diameter in described arc envelope face reduces gradually along the radially outer direction of described gear.
Further, seamlessly transit between described arc envelope face with the two side of corresponding described spline tooth.
Further, the symmetrical line in described arc envelope face is the oblique line of inclination relative to the axis of described gear.
Further, the angle between the symmetrical line in described arc envelope face and the axis of described gear is 75 °.
The beneficial effects of the utility model are:
Output shaft of gear-box gear of the present utility model, by arranging radial end face oil groove on the end face being provided with spline one end, the end face being provided with driving gear one end arranging annular oil groove and arrange oblique oil groove between annular oil groove and central through bore, can ensure that lubricant oil can be passed in central through bore, ensure the rotary lubrication of output shaft gear, avoid output shaft gear to be excessively abraded, improve working life.
By arranging the arc envelope face formed by circular arc chamfering in the end of spline, when spline engages with sleeve engage a gear, due to the existence in this arc envelope face, even if touch between spline and sleeve, arc envelope face also can produce a tangent line component, makes sleeve along this smooth-going movement in arc envelope face, and finally realize the operation of engage a gear engagement, therefore, by arranging arc envelope face, engage a gear can be made to operate more smooth-going.
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:
Fig. 1 is the structural representation of the utility model output shaft of gear-box pinion embodiment;
Fig. 2 is the A detail drawing of Fig. 1;
Fig. 3 is the B-B sectional drawing of Fig. 2.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, and to make those skilled in the art better can understand the utility model being implemented, but illustrated embodiment is not as to restriction of the present utility model.
As shown in Figure 1, be the structural representation of the utility model output shaft of gear-box pinion embodiment.The output shaft of gear-box gear of the present embodiment, comprises gear 1, and the center of described gear 1 is provided with central through bore 2, and one end of described gear 1 is provided with driving gear 3, and the other end is provided with spline 4.One end end face that described gear 1 is provided with spline 4 is provided with radial end face oil groove 5, one end end face that gear 1 is provided with driving gear 3 is provided with annular annular oil groove 6, is provided with the oblique oil groove 7 passed through for lubricant oil between described annular oil groove 6 and described central through bore 2.The oblique oil groove 7 ring uniform setting ringwise of the present embodiment, can make lubrication more even.The spline 4 of the present embodiment is involute splines, and described driving gear 3 is cylindrical gears.
The output shaft of gear-box gear of the present embodiment, by arranging radial end face oil groove 5 on the end face being provided with spline 4 one end, the end face being provided with driving gear 3 one end arranging annular oil groove 6 and arrange oblique oil groove 7 between annular oil groove 6 and central through bore 2, can ensure that lubricant oil can be passed in central through bore 2, ensure the rotary lubrication of output shaft gear, avoid output shaft gear to be excessively abraded, improve working life.
Further, all spline tooths of described spline 4 are provided with away from one end of described driving gear 3 the arc envelope face 8 formed by circular arc chamfering.The external diameter in the arc envelope face 8 of the present embodiment reduces gradually along the radially outer direction of described gear 1, seamlessly transits, can avoid bite, make gearshift more steady between arc envelope face 8 with the two side of corresponding described spline tooth.The symmetrical line 9 in the arc envelope face 8 of the present embodiment is the oblique line of inclination relative to the axis of described gear 1, and the angle α between the symmetrical line 9 in arc envelope face and the axis of described gear 1 is 75 °.
