Abstract
The utility model discloses a kind of spiral umbrella drive bevel gear, including the cone flank of tooth, top plane, cone tooth wall, main shaft, the cone tooth wall is located at the end of main shaft on the inside of the cone flank of tooth, and be located between main shaft and top plane, the center hole of indent is provided with the middle part of the cone tooth wall, depth A of the center hole is 2nd/1st to three/3rd of the height H for boring tooth wall.The shape of cone tooth wall of the present utility model and wall thickness design are more scientific reasonable, and its operating power consumption is lower, and efficiency utilization rate is higher, and operation braking is more steady, and weight is lighter, and cost is lower, are more beneficial for reducing equipment cost.Simultaneously, the center hole of indent is provided with the middle part of cone tooth wall, residualinternal stress can be preferably eliminated during spiral umbrella drive bevel gear processing and heat treatment, it is ensured that bevel gear has more good internal structure and structural strength, to reach more preferable using effect, and increase the service life.
Description
Technical field
This utility model is related to lathe drive gear, particularly a kind of spiral umbrella drive bevel gear.
Background technology
Existing lathe drive gear, particularly spiral umbrella drive bevel gear, as its wall thickness is thicker, are particularly its top flat
Wall thickness between face and the end of main shaft is especially thick, and this can consume larger kinetic energy when operation so that energy during processing
Effect utilization rate is low, and, it is easily caused the weak point that skidding is unstable, there is operating.In addition, the wall thickness of material is too
Thickness also increases material cost, and weight is heavier, increased energy consumption.Therefore, it is necessary to research and develop a kind of new spiral umbrella active conical tooth
Wheel, to overcome above-mentioned these defects.
The content of the invention
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide that a kind of operating power consumption is lower, efficiency
Utilization rate is higher, operation more steady, cost is lower, the weight lighter, residualinternal stress that preferably can be eliminated in heat treatment process,
Ensure that bevel gear has the spiral umbrella drive bevel gear of more good internal structure and structural strength.
This utility model solves the technical scheme adopted by its technical problem：A kind of spiral umbrella drive bevel gear, including
The cone flank of tooth, top plane, cone tooth wall, main shaft, the cone tooth wall are located at the end of main shaft on the inside of the cone flank of tooth, and it is flat with top to be located at main shaft
Between face, the center hole of indent in the middle part of the cone tooth wall, is provided with, depth A of the center hole is the height H for boring tooth wall
2/1sts to three/3rd.
Specifically, depth A of the center hole is 1/2nd of the height H for boring tooth wall.
The beneficial effects of the utility model are：Due to being provided with the center hole of indent in the middle part of the cone tooth wall, it is described in
Depth A of heart circular hole is 2nd/to three/3rd of the height H for boring tooth wall, so the shape of cone tooth wall of the present utility model
It is more scientific with wall thickness design that rationally its operating power consumption is lower, and efficiency utilization rate is higher, and operation braking is more steady, and weight is lighter, into
This is lower, is more beneficial for reducing equipment cost.Meanwhile, the center hole that indent is provided with the middle part of tooth wall is bored, in spiral umbrella actively
Residualinternal stress can be preferably eliminated in bevel gear making heat treatment process, it is ensured that bevel gear has more good internal structure
And structural strength, to reach more preferable using effect, and increase the service life.
Description of the drawings
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is radial section structural representation of the present utility model.
Specific embodiment
With reference to Fig. 1, a kind of spiral umbrella drive bevel gear of this utility model, including the cone flank of tooth 1, top plane 2, cone tooth wall 3, master
Axle 4, the cone tooth wall are located at the end of main shaft on the inside of the cone flank of tooth, and are located between main shaft and top plane, in the cone tooth wall
Portion is provided with the center hole 5 of indent, and depth A of the center hole is 2nd/1st to three/3rd of the height H for boring tooth wall,
Within this range, preferable efficiency and running status can be reached, meanwhile, the center hole of indent is designed as, in spiral umbrella master
Residualinternal stress can be preferably eliminated during dynamic bevel gear processing and heat treatment, it is ensured that bevel gear has more good inside structure
Make and structural strength, to reach more preferable using effect, and increase the service life.
Concrete optimal scheme, depth A of the center hole are 1/2nd of the height H for boring tooth wall, now its energy
Effect and running effect reach optimal collocation, and cost is also minimum, and with better internal structure and structural strength.This reality
Gear loss of weight can also be given with new, to the vehicle bridge loss of weight of application, to mitigate the own wt of car.
Additionally, this utility model is not limited to above-mentioned embodiment, as long as which reaches this reality with essentially identical means
With new technique effect, should all belong to protection domain of the present utility model.
