Abstract
The invention relates to a shaft sleeve for an automobile transmission shaft. The shaft sleeve for the automobile transmission shaft is provided with a shaft sleeve body. A shaft sleeve hole is formed in the center of the shaft sleeve body. A middle large step is arranged at the middle end of the outer surface of the shaft sleeve body. The shaft sleeve hole comprises a major arc, a groove and a cylindrical groove, wherein the groove is formed between the major arc and the cylindrical groove and is of an extrusion forming structure. The shaft sleeve body, the middle large step and the shaft sleeve hole are of an integrally formed structure. The shaft sleeve for the automobile transmission shaft is simple in structure, formed in an integral extrusion mode, convenient to manufacture and machine, small in fit clearance, good in lubricating effect, good in fastening effect and long in service life, reduces abrasion, reduces the repairing and replacement frequency and improves the shock absorption function of the transmission shaft.
Description
Technical field
The present invention relates to a kind of axle sleeve used for vehicle transmission shaft.
Background technology
Power transmission shaft be universal driving device power transmission shaft in can transmit the axle of power.It is a high rotating speed,
The rotary body of few supporting, therefore it dynamic balancing it is critical that.General power transmission shaft will enter before dispatching from the factory
Action balance is tested, and is adjusted on balancing machine.It is handle for the car of preposition engine rear wheel drive
The axle of main reducing gear is passed in the rotation of variator, and it can be several joint, can be by universal between saving and saving
Joint connects.
Truck drive shaft is to connect change speed gear box and the parts of drive axle, the power transmission that electromotor produces the most at last
To wheel, drive running car.Alleviate the weight of drive system, energy expenditure during operating can be reduced,
Improve the service efficiency of electromotor.
For power transmission shaft, implementation currently mainly is that axle sleeve is connected by spline fitted with axle, thus real
Existing Telescopic and shock-absorbing function, but this spline fitted structure, the most easily wear and tear, from
And cause spline fitted gap after a long time use to increase, cause looseness and abnormal sound problem, cause fastening only
Dynamic weak effect.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, it is provided that a kind of one extruding
Molding, it is simple to manufacture and process, reduces abrasion, and fit clearance is little, high lubricating effect, improves fastening stop
Effective axle sleeve used for vehicle transmission shaft.
The technical solution adopted for the present invention to solve the technical problems is: a kind of axle sleeve used for vehicle transmission shaft, tool
Sleeve body, the center of described sleeve body is had to offer axle sleeve hole, during the middle-end of its outer surface is provided with
Between big step, described axle sleeve hole includes major arc hole, groove and cylindrical hole, and described groove is located at major arc hole
With between cylindrical hole, groove is extrusion structure, described sleeve body, step broad in the middle and axle sleeve hole
Be formed in one structure.
Further, the surface roughness of the outer surface of described sleeve body is Ra3.2, described axle sleeve hole
Inwall use mirror-polishing process, its surface roughness is Ra1.6.
Further, the cross sectional shape in described major arc hole is from major arc section and straight with what described major arc section coordinated
Line segment composition.
Further, the two ends of described sleeve body carries out chamfered, and described sleeve body is with middle
Circular sliding slopes is passed through in the junction of big step.
Further, the generally circular in shape or tetragon of described step broad in the middle.
The invention has the beneficial effects as follows: present configuration is simple, the most extruded, it is simple to manufacture and process,
Reducing abrasion, fit clearance is little, high lubricating effect, improves fastening stopping effect good, reduces maintenance and changes
Frequency, service life is long, improves power transmission shaft shock-absorbing function.
Accompanying drawing explanation
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the sectional view of A-A of the present invention.
1. sleeve body in figure, 2. axle sleeve hole, 2-1. major arc hole, 2-2. groove, 2-3. cylindrical hole,
Step the most broad in the middle.
Detailed description of the invention
Presently in connection with accompanying drawing and preferred embodiment, the present invention is further illustrated.These accompanying drawings are simplification
Schematic diagram, the basic structure of the present invention is described the most in a schematic way, therefore it only shows relevant with the present invention
Composition.
One axle sleeve used for vehicle transmission shaft as shown in Fig. 1～2, has sleeve body 1, sleeve body 1
Center offers axle sleeve hole 2, and the middle-end of its outer surface is provided with step 3 broad in the middle, and described axle sleeve hole 2 includes
Major arc hole 2-1, groove 2-2 and cylindrical hole 2-3, described groove 2-2 is had to be located at major arc hole 2-1 and cylinder
Between the 2-3 of hole, groove 2-2 is extrusion structure, described sleeve body 1, step broad in the middle 3 and
Axle sleeve hole 2 is formed in one structure.
The surface roughness of the outer surface of sleeve body 1 is Ra3.2, and the inwall of described axle sleeve hole 2 uses
Being mirror-polishing process, its surface roughness is Ra1.6, and the cross sectional shape of major arc hole 2-1 is by major arc section
And the straightway composition coordinated with described major arc section.
The two ends of sleeve body 1 carries out chamfered, described sleeve body 1 and the company of step 3 broad in the middle
Meet place by circular sliding slopes, the generally circular in shape or tetragon of step 3 broad in the middle, simple in construction simultaneously, one
Body is extruded, it is simple to manufactures and processes, and reduces abrasion, and fit clearance is little, high lubricating effect, improves tight
Gu stopping effect is good, reducing maintenance and replacement frequency, service life is long, improves power transmission shaft shock-absorbing function.
Above-described embodiment only for technology design and the feature of the present invention are described, its object is to allow and is familiar with this skill
The personage of art will appreciate that present disclosure and is carried out, and can not limit the protection model of the present invention with this
Enclose, all equivalence changes made according to spirit of the invention or modification, all should contain the protection in the present invention
In the range of.
