Abstract
A kind of output shaft, including shaft body；The shaft body mainly has several axis bodies；The shaft body both ends are respectively spindle nose and axis tail；Spline part is provided at spindle nose；Bolt hole is offered at axis tail, and heat dissipation channel is provided between spline part and bolt hole；Heat dissipation channel is connected to outside shaft body by bolt and heat release hole.Heat dissipation channel is arranged by setting in the utility model between spline part and bolt hole, and directly the heat that spline part friction generates is discharged, increases service life.
Description
Technical field
The utility model is a kind of output shaft, belongs to automotive transmission technical field.
Background technique
Existing output shaft is typically all that the teeth portion or spline part by being provided thereon are connected to realize and pass with moving component
Dynamic, during high speed rotation, since the frictional force between the field of conjugate action is larger, relative velocity is big, causes region of engagement temperature high.
Generally it can be coated with lubricating oil in teeth portion or spline part, make to form oil film, less wear between the field of conjugate action.But due between the field of conjugate action
Friction causes temperature excessively high, and is easy to make deterioration of lubricant, cannot give teeth portion or spline part sufficient lubrication, make the mill between the field of conjugate action
It damages more serious, influences the service life of output shaft.
Therefore, it is further improved.
Utility model content
The purpose of this utility model is: providing a kind of simple and reasonable, output shaft that can effectively radiate.
To realize the above-mentioned technical purpose, the technical solution adopted in the utility model is as follows:
A kind of output shaft, including shaft body；The shaft body mainly has several axis bodies；The shaft body both ends point
It Wei not spindle nose and axis tail；Spline part is provided at the spindle nose；Bolt hole, the spline part are offered at the axis tail
Heat dissipation channel is provided between bolt hole；Heat dissipation channel is connected to outside shaft body by bolt and heat release hole.
It is provided with through-hole at the bolt-center, and is connected to inside and outside shaft body.
The heat release hole is distributed in the two sides up and down of shaft body.
In vertical distribution between the heat release hole and heat dissipation channel.
Rectangular spline is provided on the spline part.
Heat dissipation channel is arranged by setting in the utility model between spline part and bolt hole, and directly spline part rubs and produces
Raw heat discharge, increases service life.
Detailed description of the invention
The utility model can be further illustrated by the nonlimiting examples that attached drawing provides；
Fig. 1 is the structural schematic diagram of the utility model.
In figure, 1 is shaft body, and 2 be spindle nose, and 3 be axis tail, and 4 be bolt hole, and 5 be heat release hole, and 6 be heat dissipation channel.
Specific embodiment
It is right with reference to the accompanying drawings and examples in order to make those skilled in the art that the utility model may be better understood
The technical solution of the utility model further illustrates.
Referring to Fig. 1, a kind of output shaft, including shaft body；Shaft body 1 mainly has several axis bodies；1 both ends of shaft body difference
For spindle nose 2 and axis tail 3；Spline part is provided at spindle nose；Bolt hole 4 is offered at axis tail, is set between spline part 1 and bolt hole 4
It is equipped with heat dissipation channel 6；Heat dissipation channel is connected to outside shaft body by bolt and heat release hole 5.
Preferably, it is provided with through-hole at the bolt-center, and be connected to inside and outside shaft body 1.
Preferably, heat release hole 5 is distributed in the two sides up and down of shaft body.
Preferably, in vertical distribution between heat release hole 5 and heat dissipation channel 6.
Preferably, the first spline part is provided at spindle nose 2.
Preferably, rectangular spline is provided on the first spline part.
Above-described embodiment is merely exemplary to illustrate the principle and effect of the utility model, and not for limitation, this is practical new
Type.Any person skilled in the art can all carry out above-described embodiment under the spirit and scope without prejudice to the utility model
Modifications and changes.Therefore, all those of ordinary skill in the art are without departing from the revealed spirit of the utility model
With all equivalent modifications completed under technical idea or change, should be covered by the claim of the utility model.
