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 is because precision is relatively low when on commercial vehicle, therefore the caused working clearance is larger, and gear is easily beaten when coordinating
Sliding, relatively low so as to the operational efficiency of whole spiral bevel gear, service life is shorter.
Utility model content
The utility model is to provide a kind of high-precision commercial vehicle driving axle spiral bevel gear, and it mainly solves prior art
Existing spiral bevel gear use is because precision is relatively low when on commercial vehicle, therefore the caused working clearance is larger, and gear exists
Easily skidded during cooperation, the technical problem of service life shorter grade relatively low so as to the operational efficiency of whole spiral bevel gear.
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals：
High-precision commercial vehicle driving axle spiral bevel gear of the present utility model, including spiral bevel driving gear and passive spiral
Bevel gear, described spiral bevel driving gear include screw body, and screw body is provided with active denticle, active denticle it is interior
End end face is provided with inclined-plane, and the angle α of inclined-plane and vertical plane is 16-18 °, and passive spiral bevel gear includes umbrella tooth body, umbrella tooth
Circle distribution has a passive denticle on body, and the bottom surface of umbrella tooth body is provided with screw, the outer face of passive denticle with passive denticle
The angle β on surface is 88-92 °, and the end of screw body is provided with the locating slot that section is triangle, the vertical plane and screw rod of locating slot
The spacing of body central line is 0.1-2mm, and the shaft of screw body is provided with spline.Pass through angle α and angle β special setting
Value so that the fit precision of active denticle and passive denticle reaches higher level.The locating slot of triangle can make screw rod sheet
Body is easier to by fixed conveyor, because vertical plane and the screw body center line of locating slot have certain spacing, therefore fit precision
It is higher.
Preferably, the shaft of the screw body of described spline the inner is provided with knurling layer.It can be made by knurling layer
Frictional force can further be increased when coordinating with other parts by obtaining spiral bevel driving gear, prevent from skidding.
Preferably, the root of described active denticle is provided with caulking groove, it is provided with caulking groove and strengthens alloy block.By strengthening closing
Gold bullion can strengthen the intensity of whole active denticle, and strengthening alloy block can be made up of nichrome, further ensure transmission
Accuracy.
Preferably, the inclined-plane in described passive tooth body residing for the end face of end is provided with bootstrap block.Can be with by bootstrap block
Guiding active denticle is coordinated with passive denticle, so as to which fit precision is higher.
Therefore, the utility model can improve the precision of transmission by the flank of tooth angle numerical value of active denticle, passive denticle,
It may further ensure that the compactness of cooperation using locating slot, knurling layer simultaneously, then by boss alloy, bootstrap block, can be with
Ensure that whole spiral bevel gear precision is higher, it is simple and reasonable for structure.
