Abstract
The invention discloses a shaft type step surface transition structure, and the shaft type step surface transition region is provided with two transition arcs, and the dimension of the arc radius R#2 is more than 1 mm, and the dimension of the arc radius R#1 is more than 0.5 mm and is less than the dimension of the radius R#2. The distance A between the contact points of the cylindrical surface and the arc R#2 is more than 0.05mm; an included angle X between the line which crosses the arc R#2 terminal point and the circle center O2 thereof and the vertical line is 8-82 degrees; the distance B between the arc R#1 circle center and the cylindrical surface is more than one third of the arc R#2. The invention solves the problem of weak zone which is generated by stress concentration of the shaft step surface, thereby overcoming part crack, fracture and other failures.
Description
Technical field
The present invention relates to a kind of axle class step surface transition structure, belong to auto parts and components axle class formation field.
Background technique
Automobile axial workpiece step surface transition zone generally adopts tool withdrawal groove or small round corner transition, and these two kinds of transition methods all can make part produce weak area, thereby causes the Problem of Failure such as part crack, fracture.The present invention can well address this problem.
Summary of the invention
Technical problem to be solved by this invention is: a kind of Novel shaft class step surface transition structure that can solve axial workpiece step surface crossover position problem of stress concentration is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
An axle class step surface transition structure, has 2 transition arcs in axle class step surface transition zone, to the requirement of each circular arc, is: more than radius of arc R# 2 size 1mm, radius of arc R# 1 size is greater than 0.5mm, is less than circular arc R # 2 size.
Preferably, cylndrical surface 1 is more than 0.05mm with circular arc R # 2 point of contact distance A.
Preferably, circular arc R # 2 terminal and its center of circle O2 line and X ° of scope of vertical line angle are 8 °-82 °.
Preferably, the distance B of the circular arc R # 1 center of circle and cylndrical surface 1 is the more than 1/3rd of circular arc R # 2 radius.
On basis of the present invention, transition arc can also have more than 2.
The invention solves axle class step surface stress and concentrate generation weak area, overcome the Problem of Failure such as part crack, fracture.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the partial enlarged drawing of C part.
Embodiment
As illustrated in fig. 1 and 2, a kind of axle class step surface transition structure, has 2 transition arcs in axle class step surface transition zone, and circular arc R # 1 centre point is O1, and circular arc R # 2 centre point is O2.
To the requirement of each circular arc, be: more than radius of arc R# 2 size 1mm, radius of arc R# 1 size is greater than 0.5mm, is less than circular arc R # 2 size.
Circular arc R # 2 terminal and its center of circle O2 line and X ° of scope of vertical line angle are 8 °-82 °.
The distance B of the circular arc R # 1 center of circle and cylndrical surface 1 is the more than 1/3rd of circular arc R # 2 radius.
Certainly, above-mentioned explanation is not limitation of the present invention, and the present invention is also not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present invention, the variation of making, remodeling, interpolation or replacement, all should belong to protection scope of the present invention.
