The outer wall of body is arcuate structure；Wheel axle portion is provided with axis hole with taking turns the other end of teeth portion connection end, and the hole wall of axis hole is provided with
The limited block of arch, hole wall circular array of the limited block along axis hole are arranged, and spacing hole, the hole wall of axis hole are formed between limited block
On be additionally provided with the boss being placed between two adjacent limited blocks, the boss limited block adjacent with two is connected；Taking turns teeth portion is
Conical structure, it is 0.8-1.2 to take turns the basal diameter of teeth portion and height ratio；Wheel teeth portion is provided with chamfering.But this spiral
Bevel gear use precision when on picking-up vehicle is poor, and spiral bevel gear also needs to cut to add after machining by roll flute
Work, process is more numerous and diverse, so as to which the production cost of whole spiral bevel gear manufacture is higher.
Utility model content
The utility model is to provide one kind less without cutting picking-up vehicle driving axle spiral bevel gear, and it mainly solves existing skill
Spiral bevel gear use present in art precision when on picking-up vehicle is poor, and spiral bevel gear also needs after being machined by roll flute
Machining is carried out, process is more numerous and diverse, so as to the technical problem of the higher grade of production cost of whole spiral bevel gear manufacture.
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals：
It is of the present utility model few without cutting picking-up vehicle driving axle spiral bevel gear, including spiral bevel driving gear and passive spiral shell
Bevel gear is revolved, described spiral bevel driving gear includes screw body, and screw body is provided with active denticle, passive spiral umbrella
Gear includes umbrella tooth body, and circle distribution has passive denticle on umbrella tooth body, and the bottom surface of umbrella tooth body is provided with screw, screw rod sheet
First body of rod that body is sequentially reduced by diameter, second body of rod, the 3rd body of rod, the 4th body of rod form, and the 4th body of rod outer end is provided with fixed
Potential head, is provided with the conical surface body of rod between second body of rod and the 3rd body of rod, the 3rd body of rod and the 4th body of rod are provided with spline.This practicality is new
For type after the fluid roll flute of gear grinding machines, spiral bevel driving gear directly grinds first body of rod that diameter differs, second body of rod,
Three bodies of rod, the 4th body of rod and the conical surface body of rod, positioning head, can be so complete in roll flute by arcwall face transition between each body of rod
Cheng Hou, it is less without extra progress machining again, or the process of machining, production cost is greatly decreased.
Preferably, the inner end face of described active denticle is provided with inclined-plane, the angle α of inclined-plane and vertical plane is 16-
18 °, the angle β of the outer face of passive denticle and passive denticle upper surface is 88-92 °.Set by angle α and the special of angle β
Definite value so that with regard to that can reach such precision after roll flute machining, fitness reaches optimal for active denticle and passive denticle.
Preferably, described positioning head is provided with symmetrically arranged two locating slots.It is permissible by double locating slots
Fit precision is higher.
Preferably, being provided with caulking groove in the endoporus of described umbrella tooth body, embedded with alloy-layer is strengthened in caulking groove, strengthen closing
Layer gold protrusion umbrella tooth body endoporus 0.1-0.5mm.Intensity when can strengthen whole umbrella tooth body transmission by strengthening alloy-layer,
Strengthening alloy-layer can be made up of nichrome.Strengthen the endoporus of alloy-layer slightly protruding umbrella tooth body, can so extend whole
The service life of individual spiral bevel gear, and can reduce and cut this process.
Therefore, the utility model is in spiral bevel driving gear and passive spiral bevel gear by directly processing each shape,
Subsequent processing operations are thus greatly reduced, few effect without cutting can be reached, reduce production cost, and can protect
The transmission accuracy of spiral bevel gear is demonstrate,proved, it is simple and reasonable for structure.
