The technical solution of the utility model is: a kind of automobile axle comprises initiatively helical bevel gear and driven helical bevel gear by the moving spiral bevel gear pair of Equidep main quilt, initiatively helical bevel gear and driven helical bevel gear are intermeshing, the number of teeth of described active helical bevel gear is 8, addendum is 5.69mm, whole depth is 7.94mm, pressure angle is 20 °, and Mean spiral angle is 52 °, and external diameter is 76.73mm; The number of teeth of described driven helical bevel gear is 39, and addendum is 1.17mm, and whole depth is 7.94mm, and pressure angle is 20 °, and Mean spiral angle is 52 °, and external diameter is 205.84mm.
The utility model compared with prior art has following effect:
1. the utility model has under equal conditions improved 10%-25% than the intensity of convergent tooth.
2. engagement noise of the present utility model changes low frequency noise into by the high frequency noise of convergent tooth, and it is more comfortable that people sounds, has improved simultaneously and has received oily whistle.
3. to need five lathes be a set of unit to the gear of the moving convergent tooth of processing main quilt, and the gear of processing the moving Equidep of main quilt of the present utility model only needs two lathes.Floor space is little, and remaining space can be installed miscellaneous equipment again, boosts productivity, and has saved labor intensity and has greatly reduced human and material resources cost.
4. because Equidep cutting does not need independent rough lumber, so do not need to carry out surplus distribution, workpiece is i.e. directly processing after installing, and simple to operate, cutting quality is relatively stable.On its cutterhead, only have two kinds, inside and outside blade, traditional convergent tooth has three kinds, rough lumber blade and inside and outside blade, makes it on the cutterhead of same diameter, can arrange more multi-blade group, contributes to improve cutting efficiency.
5. the shape of contact area of the present utility model changes the revised inner opposite angle slanted bar of profile of tooth shape into, can effectively reduce the receptance of heat treatment deformation, assembly error, stand under load skew, thereby improve the conformity of contact area, improve intensity, reduce noise, reduced the labor intensity of assembling.
6. Equidep of the present utility model can adopt dry cutting, and does not use lubricant oil to wet and cuts, and this processing method has not only reduced the pollution of factory work environment, and has reduced the loss of the first lubricant oil of annual hundreds of thousands.Its cutting rate is cut and can be improved more than 1 times than conventional wet.
7. the utility model is particularly useful for Great Wall SUV automobile axle.
