The bottom land connection end of groove is provided with the second wear body for being connected with the bottom land of the second stopper slot, the first wear body and second wear-resisting
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 is poor using intensity when on pickup truck, and bevel gear easily produces fracture in the course of the work, so as to trigger peace
Full accident.
Utility model content
The utility model is to provide a kind of high-strength light lorry driving axle spiral bevel gear, and it mainly solves existing skill
Spiral bevel gear present in art is poor using intensity when on pickup truck, and bevel gear easily produces disconnected in the course of the work
Split, so as to trigger the technical problem of security incident etc..
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals：
High-strength light lorry driving axle spiral bevel gear of the present utility model, 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, active denticle
Inner end face is provided with inclined-plane, and the angle α of inclined-plane and vertical plane is 18-22 °, and the screw body outer end where active denticle is by adding
Strong ring connection end, passive spiral bevel gear include umbrella tooth body, and circle distribution has passive denticle, umbrella tooth sheet on umbrella tooth body
The bottom surface of body is provided with screw, and the angle β of the outer face of passive denticle and passive denticle upper surface is 88-92 °.The utility model profit
With the mutual angular compliance of the outer face on the inclined-plane on active denticle and passive denticle, spiral bevel driving gear can be ensured
Cooperation intensity between passive spiral bevel gear, so as to each denticle coordinate when angle can be just right, gap compared with
It is small.Bonding strength between termination and active denticle section can be ensured by reinforcing ring.
Preferably, the shaft of described screw body is provided with locating slot, the both ends of locating slot are designed with chamfering.Positioning
The depth of groove is shallower, on the one hand can ensure the intensity of whole screw body, on the other hand can also play a part of positioning.If
The intensity that locating slot opens up can be ensured by putting chamfering.
Preferably, the inner of described termination is provided with the conical surface, the angle γ of the conical surface and horizontal plane is 28-32 °, and the conical surface is again
It is connected by arc surface with reinforcing ring.Inner in termination sets the conical surface, when can so prevent that spiral bevel driving gear from running
It is broken by during shearing force in end.
Preferably, the caulking groove of triangle is provided with the inner tooth root of described umbrella tooth body, embedded with reinforcement in caulking groove
Alloy-layer.Strengthen alloy-layer to be typically made up of the commercially available alloying component that can play abrasion resistant effect, can be nichrome.
Therefore, the utility model can be played using spiral bevel driving gear and the angular compliance of passive spiral bevel gear
Coordinate gapless, ensure stress intensity, while whole spiral bevel gear is further enhanced using each conical surface, reinforcement alloy-layer
Intensity, it is simple and reasonable for structure.
