Abstract
The utility model discloses a kind of bevel gear pairs, the driven wheel of differential of connection is engaged including drive bevel gear, with drive bevel gear, a starting taper face is respectively formed between the drive bevel gear and the big end root circle and the tooth root conical surface of driven wheel of differential, the shape of the chamfering of the big end outside circle in the starting taper face and drive bevel gear of the drive bevel gear matches, and the chamfer shape of the big end outside circle in the starting taper face and driven wheel of differential of the driven wheel of differential matches.After adopting the above technical scheme, bevel gear pair provided by the utility model, can help the normal engagement of bevel gear, ensure that the vertex of a cone of two bevel gears is met at a bit, so as to increase wear resistance, extends its service life, and step is reinforced by setting, increase the intensity of big end gear teeth outer rim.
Description
Technical field
The utility model relates to a kind of bevel gear pairs.
Background technique
There must be correct relative position between drive bevel gear and driven wheel of differential, two bevel gears engaged transmission can be made
When impact noise it is smaller, and the gear teeth wear along its length it is more uniform.Therefore, true in bevel gear engagement operation process China
The relative position for protecting drive bevel gear and driven wheel of differential does not change because taking turns odontotripsis or axial float for reducing bevel gear
Secondary abrasion, therefore it is extremely important for extending its service life.
Utility model content
In view of the above-mentioned problems, the utility model provides a kind of bevel gear pair.
A kind of in order to solve the above technical problems, the technical scheme adopted by the utility model is: bevel gear pair, including actively
Bevel gear, the driven wheel of differential that connection is engaged with drive bevel gear, the big end tooth root of the drive bevel gear and driven wheel of differential
A starting taper face, the starting taper face of the drive bevel gear and the big end outside circle of drive bevel gear are respectively formed between the round and tooth root conical surface
The shape of chamfering match, the chamfer shape phase of the big end outside circle in the starting taper face and driven wheel of differential of the driven wheel of differential
Matching.
Further, one is also formed below the big end root circle of the drive bevel gear reinforce step.
By the above-mentioned description to the utility model structure it is found that compared to the prior art, the utility model has following excellent
Point:
1, the normal engagement of bevel gear can be helped, it is ensured that the vertex of a cone of two bevel gears is met at a bit, resistance to so as to increase
Grit extends its service life.
2, step is reinforced by setting, increases the intensity of big end gear teeth outer rim.
Detailed description of the invention
The attached drawing constituted part of this application is used to provide a further understanding of the present invention, the utility model
Illustrative embodiments and their description are not constituteed improper limits to the present invention for explaining the utility model.In attached drawing
In:
Fig. 1 is a kind of structural schematic diagram of bevel gear pair of the utility model；
Fig. 2 is the enlarged drawing in Fig. 1 at A.
In figure: the big end outside circle 2. of 12. drive bevel gear of starting taper face of 1. drive bevel gear, 11. drive bevel gear
The big end outside circle 3. of 22. driven wheel of differential of starting taper face of 21. driven wheel of differential of driven wheel of differential reinforces step.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
Embodiment
With reference to Fig. 1 and Fig. 2, a kind of bevel gear pair engages the driven of connection including drive bevel gear 1, with drive bevel gear 1
A starting taper face, initiative taper are respectively formed between the big end root circle and the tooth root conical surface of bevel gear 2, drive bevel gear and driven wheel of differential
The shape of the chamfering of the big end outside circle 12 in the starting taper face 11 and drive bevel gear 1 of gear 1 matches, and driven wheel of differential 2 is led
The conical surface 21 and the chamfer shape of the big end outside circle 22 of driven wheel of differential 2 match, below the big end root circle of drive bevel gear 1
It also forms one and reinforces step 3.Bevel gear pair provided by the utility model can help the normal engagement of bevel gear, it is ensured that two cone teeth
The vertex of a cone of wheel is met at a bit, so as to increase wear resistance, extends its service life, further, reinforces platform by setting
Rank increases the intensity of big end gear teeth outer rim.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
