Abstract
The utility model discloses a drive shaft. The drive shaft comprises a shaft body, wherein a cylindrical boss is arranged at the front end of the shaft body, and the rear end of the shaft body is provided with a cylindrical hole; a round hole is formed outside the cylindrical boss; and an annular step surface is formed between the shaft body and the cylindrical boss. The drive shaft overcomes the defects in the prior art, and is simple in design and reasonable in structure; and due to the reasonably designed shaft body structure, the shaft body is conveniently to be firmly connected and the service life is long.
Description
Technical field
Model utility relates to the live axle technical field, specifically belongs to a kind of live axle.
Background technique
General commonly used live axle is that the spline housing by profile band triangular key tooth is pressed into live axle, and the end face three sections weld seams welding combinations that all distribute are because two component are surperficial cure process, the spline jacket wall is thin, heat treatment deformation is large, and it is unstable to be pressed into rear spline coaxality, and working life is short.
The model utility content
The purpose of model utility has provided a kind of live axle, has overcome the deficiencies in the prior art, and simplicity of design is rational in infrastructure, and by the appropriate design axis structure, axis body is easy to connect firmly, long service life.
The technological scheme that model utility adopts is as follows:
A kind of live axle comprises axis body, and described axis body front end has cylinder table, and the rear end has cylindrical hole, and cylinder table is provided with circular hole outward, is provided with the annular table terrace between axis body and the cylinder table.
The chromium plating of described axis body intermediate portion.
Compared with the prior art, the beneficial effect of model utility is as follows:
The model utility project organization is reasonable, improves the stability of transmission and the intensity of transmission, and fabricating cost is low, has improved manufacturing efficiency.
Description of drawings
Fig. 1 is the structural representation of model utility.
Embodiment
