Abstract
The invention discloses a local reciprocating driving gear. The half-edge driving gear comprises a gear body and a spline groove which is formed in the center of the gear body. Gear teeth are arranged on the outer edge, surrounding the gear body, of part of the gear body. The gear teeth are arranged on the outer edge of part of the gear body so that the production cost of the gear can be reduced.
Description
Technical field
The present invention relates to a kind of local and back and forth drive gear。
Background technology
It is known that existing driving gear includes a circular gear and is distributed in the outer peripheral gear teeth of circular gear body。Gear center is provided with spline。When gear does the rotation of 360 degree, to contact one by one with all gear teeth with the parts of gear teeth meshing。But when gear does the reciprocating rotation less than 360 degree, use the words of gear of the prior art to have operative gear idle running, cause the waste of resource。
Summary of the invention
It is an object of the invention to overcome the defect existed in prior art, it is provided that a kind of local saving cost back and forth drives gear。
For achieving the above object, technical scheme provides a kind of local and back and forth drives gear, and described half of driving wheel includes gear and is arranged on the spline at gear center, is toothed around around described gear partial outer edge。The gear teeth are arranged at gear partial outer edge and can reduce the production cost of gear。
As preferably, the described gear teeth are arranged at continuous print gear outward flange。Such design is the further optimization to scheme。
As preferably, described tooth distribution region central angle is 100 degree。Such design is the further optimization to scheme。
As preferably, described gear center is provided with annular concave platform, and described spline is arranged on annular concave platform inwall。Such design is can to save material further。
As preferably, described tooth surface is provided with quenching layer。Such design is favorably improved the intensity of the gear teeth
Advantages of the present invention and having the beneficial effects that: the gear teeth are arranged at gear partial outer edge and can reduce the production cost of gear。
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram。
In figure: 1, gear；2, spline；3, the gear teeth；4, annular concave platform。
Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is further described。Following example are only for clearly illustrating technical scheme, and can not limit the scope of the invention with this。
As it is shown in figure 1, a kind of local back and forth drives gear, described half of driving wheel includes gear 1 and is arranged on the spline 2 at gear 1 center, is toothed around 3 around described gear 1 partial outer edge。
The described gear teeth 3 are arranged at continuous print gear 1 outward flange。
The described gear teeth 3 distributed areas central angle is 100 degree。
Described gear 1 center is provided with annular concave platform 4, and described spline 2 is arranged on annular concave platform 4 inwall。
The described gear teeth 3 surface is provided with quenching layer。
The above is only the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, under the premise without departing from the technology of the present invention principle; can also making some improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention。
Claims (2)
