The axle journal of end shaft is by being arranged bearing support thereon on the supporting rack of the pump housing.Transmission shaft transmits the stability ten of torque
Divide important.
Current automobile transmission shaft is wear-resisting, compressive property is poor, is further improved.
Utility model content
The purpose of this utility model is to provide a kind of high strength driving shafts, to solve mentioned above in the background art ask
Topic.
To achieve the above object, the utility model provides the following technical solutions：A kind of high strength driving shaft, including axis body,
The axis body both ends are respectively fixed with spindle nose, and the center line of the spindle nose and axis body centerline are described in same horizontal line
The surface of spindle nose is equipped with annular knurl, and the junction of the axis body and spindle nose is fixedly welded with dowel, the both ends difference of the spindle nose
It is provided with annular groove, and is connected with stirrup in the annular groove, is welded with cross reinforcing on the axis body outer wall, and described
Cross reinforcing setting goes back heap between two annular grooves, on the outer wall of the axis body and the outer wall of spindle nose and is welded with wearing layer.
Preferably, the wearing layer uses high-wear-resistant alloy；The high-wear-resistant alloy is cobalt chromium tungsten hard alloy, described resistance to
Mill layer thickness is 1mm-3mm.
Preferably, the depth of the annular groove is 3mm-5mm, width 5mm-10mm.
Preferably, the six roots of sensation is arranged in the cross reinforcing.
Compared with prior art, the utility model has the beneficial effects that：
（1）The utility model is simple in structure, has the advantages that high intensity, wear-resisting, resistance to compression, wherein distinguishes at the both ends of spindle nose
It is provided with annular groove, and is connected with stirrup in annular groove, using this structure, can effectively prevent axis body both ends from opening
It splits, phenomenon of rupture；In addition, the junction of axis body and spindle nose is fixedly welded with dowel, it can prevent spindle nose from occurring phenomenon of rupture,
Ensure its use reliability.
（2）Heap, which is gone back, in the utility model, on the outer wall of axis body and the outer wall of spindle nose is welded with wearing layer；Wearing layer is using high resistance to
Break-in gold；High-wear-resistant alloy is cobalt chromium tungsten hard alloy, which can improve the wearability of axis body and spindle nose surface, into one
Step extends the service life of transmission shaft.
（3）In the utility model, cross reinforcing is welded on axis body outer wall, the six roots of sensation, Neng Gouyou is arranged in cross reinforcing
Effect prevents axis body use from metaboly occur in the process.
Description of the drawings
Fig. 1 is the utility model overall structure diagram.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Referring to Fig. 1, the utility model provides a kind of technical solution：A kind of high strength driving shaft, including axis body 1, it is described
1 both ends of axis body are respectively fixed with spindle nose 2, and the center line of the spindle nose 2 and 1 centerline of axis body are described in same horizontal line
The surface of spindle nose 2 is equipped with annular knurl 3, the surface roughness of each spindle nose
Ra ≤ 1.6；The junction of the axis body 1 and spindle nose 2 is fixedly welded with dowel 4, the both ends point of the spindle nose 2
It is not provided with annular groove 5, and is connected with stirrup 6 in the annular groove 5, cross reinforcing is welded on 1 outer wall of the axis body
7, and the cross reinforcing 7 is arranged between two annular grooves 5, the six roots of sensation is arranged in cross reinforcing 7, and the lateral of setting is reinforced
Muscle can effectively prevent metaboly occur during axis body use；The depth of annular groove 5 is 3mm-5mm, and width is
5mm-10mm；Heap, which is gone back, on the outer wall of the axis body 1 and the outer wall of spindle nose 2 is welded with wearing layer；Wearing layer uses high-wear-resistant alloy；Institute
It is cobalt chromium tungsten hard alloy to state high-wear-resistant alloy, and the wear-resisting layer thickness is 1mm-3mm, which can improve axis body and axis
The wearability of head surface further extends the service life of transmission shaft.
In the utility model, the both ends of spindle nose have annular groove, and stirrup is connected in annular groove, using this
Structure, can effectively prevent that axis body both ends are cracking, phenomenon of rupture；In addition, welding is fixed in the junction of axis body and spindle nose
There is dowel, can prevent spindle nose from phenomenon of rupture occur, it is ensured that its use reliability.
In conclusion the utility model is simple in structure, have the advantages that high intensity, wear-resisting, resistance to compression, it is not easy to break, make
Use long lifespan.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is appreciated that can these embodiments be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaiied
