Abstract

An eccentric shaft belongs to the field of shaft parts, and comprises an eccentric shaft body, a left rotating shaft and a right rotating shaft, wherein the left and the right rotating shafts are arranged at the left and the right ends of the eccentric shaft body respectively, and a groove is formed on the left rotating shaft. The eccentric shaft solves the problem that the eccentric shaft of the prior art has high production cost. The utility model has the advantages that the materials required for manufacturing are reduced on the basis that the strength is ensured, thereby reducing the production cost.

Description

Eccentric shaft

Technical field

The utility model relates to a kind of axial workpiece, particularly a kind of eccentric shaft.

Background technique

At present, the eccentric shaft of prior art generally comprises eccentric body shaft, left rotary shaft and the right spindle that is solid construction, and left rotary shaft and right spindle are separately positioned on the two ends, the left and right sides of eccentric body shaft.Though the eccentric shaft of said structure has stronger intensity, because it is a solid construction, the material of therefore making required use is more, thereby makes that the cost of production of prior art eccentric shaft is higher.

The model utility content

The technical problems to be solved in the utility model is, provides a kind of on the basis of proof strength, can reduce the material of making required use, thus the eccentric shaft that reduces production costs.

For solving the problems of the technologies described above, the utility model provides a kind of eccentric shaft of following structure: comprise eccentric body shaft, left rotary shaft and right spindle, left rotary shaft and right spindle are located at the two ends, the left and right sides of eccentric body shaft respectively, wherein, left rotary shaft is provided with groove, and the wall thickness of left rotary shaft is not less than 12% of left rotary shaft outer diameter.

Eccentric shaft described in the utility model, wherein, the wall thickness of left rotary shaft is 12%, 13%, 14%, 15% or 16% of a left rotary shaft outer diameter.

After adopting said structure, unlike the prior art, the utlity model has following advantage: because the utility model eccentric shaft is provided with groove on left rotary shaft, therefore reduced the material of making the required use of the utility model eccentric shaft, thereby reduced the cost of production of the utility model eccentric shaft, and 12% the purpose that the wall thickness of left rotary shaft is not less than the left rotary shaft outer diameter in the utility model eccentric shaft is in the intensity that guarantees left rotary shaft, thereby guarantees the normal use of the utility model eccentric shaft.

Description of drawings

Fig. 1 is the broken section structural representation of the utility model eccentric shaft.

Embodiment

Below in conjunction with the drawings and specific embodiments the model utility eccentric shaft is described in further detail.

As shown in Figure 1, in this embodiment, the model utility eccentric shaft comprises eccentric body shaft 1, left rotary shaft 2 and right spindle 3, and left rotary shaft 2 and right spindle 3 are located at the two ends, the left and right sides of eccentric body shaft 1 respectively, left rotary shaft 2 is provided with groove 4, and the wall thickness of left rotary shaft 2 is 12% of left rotary shaft 2 outer diameters.

Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
