Abstract
The utility model discloses a gear, which comprises a hub, wherein the hub is provided with an internal reinforcing part, an external reinforcing part and a connection part for connecting the internal reinforcing part with the external reinforcing part; the internal reinforcing part is provided with a central hole; the external reinforcing part is provided with outer teeth; the left end of the internal reinforcing part is positioned at the left end of the external reinforcing part; and the right end of the internal reinforcing part is positioned at the right end of the external reinforcing part. The gear has the advantages of small weight, capability of effectively unloading stress, high strength and long life.
Description
Technical field
The utility model relates to gear.
Background technique
Existing automobile-used gear mostly weight is very big, and materials are more, and cost is higher, effort inconvenience especially in the installation and transportation process, and in forging process, also increased burden to forging equipment, and the effect that gear is subjected to driving force is easy to damage.
Summary of the invention
Problem to be solved in the utility model provides gear, and weight is little, can effectively unload stressedly, and intensity is big, and the life-span is long.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme: gear, comprise wheel hub, the joint that described wheel hub has interior reinforcing part, outer reinforcing part and connects inside and outside reinforcing part, reinforcing part is provided with center hole in described, described outer reinforcing part is provided with external tooth, and the left end of described interior reinforcing part is positioned at the left end of outer reinforcing part, and the right-hand member of described interior reinforcing part is positioned at the right-hand member of outer reinforcing part.Alleviate the weight of gear itself, effectively unload joint stressed in transmission process.
Improved, an end of described joint is connected with the middle part of interior reinforcing part, the other end is connected with the middle part of outer reinforcing part, and arc transition is passed through in the jointing place of described joint and inside and outside reinforcing part.Avoid the stress of jointing place to concentrate.
Improved, the width of described joint is 1/3rd of interior reinforcing part width.Guarantee when alleviating the weight of gear itself joint and inside and outside reinforcing part join strength.
Improved, the hole wall upper edge of described center hole is axially arranged with keyway.
Improved, the surface of described external tooth and wheel hub is equipped with hardened layer, and the degree of depth of described hardened layer is 0.5～0.7mm.Strengthen the intensity of part of the force, alleviate wearing and tearing.
Beneficial effect:
After adopting technique scheme, this model utility gear weight is little, can effectively unload stressedly, and intensity is big, and the life-span is long.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
Fig. 1 is the structural representation of a kind of mode of execution of the utility model.
Embodiment
As shown in Figure 1, gear, comprise wheel hub 2, described wheel hub has interior reinforcing part 21, in outer reinforcing part 22 and the connection, the joint 23 of outer reinforcing part, reinforcing part is provided with center hole 3 in described, described outer reinforcing part is provided with external tooth 1, the left end of reinforcing part is positioned at the left end of outer reinforcing part in described, the right-hand member of reinforcing part is positioned at the right-hand member of outer reinforcing part in described, one end of described joint is connected with the middle part of interior reinforcing part, the other end is connected with the middle part of outer reinforcing part, described joint and in, arc transition is passed through in the jointing place of outer reinforcing part, the width of described joint is 1/3rd of interior reinforcing part width, the hole wall upper edge of described center hole is axially arranged with keyway 4, and the surface of described external tooth and wheel hub is equipped with hardened layer, and the degree of depth of described hardened layer is 0.5～0.7mm.
Except above preferred embodiment, the utility model also has other mode of execution, those skilled in the art can make various changes and distortion according to the utility model, only otherwise break away from spirit of the present utility model, all should belong to the defined scope of the utility model claims.
