Description
The present invention relates to a kind of main reducing gear, more particularly to a kind of automobile main reducer bevel gear structure.
Because large-scale truck is more and more, it is also increasing for the demand of axle main speed reducer, axle main speed reducer is that automotive transmission reduces rotating speed, increase the critical piece of moment of torsion, usual axle main speed reducer includes that drive bevel gear and driven wheel of differential are constituted, drive bevel gear is intermeshed with driven wheel of differential, the rotation of drive bevel gear drives work by driven wheel of differential rotation, but operationally driven wheel of differential is broken first often, and driving gear intensity also has affluence, but because of driven pulley earlier period damage, driving wheel is set also to damage therewith, cause gear pair initial failure, life-span is not enough.
Present invention solves the technical problem that：A kind of bevel gear structure of main reducing gear is to provide, the service life of bevel gear is not only extended, and reaches the double effectses not only strengthened gear but also reduce noise.
In order to solve the above technical problems, the present invention provides a kind of bevel gear structure of main reducing gear, including intermeshing drive bevel gear and driven wheel of differential, the drive bevel gear includes the big end of drive bevel gear, end face and axle, it is characterised in that：A diameter of D1=230.5mm at the big end of drive bevel gear, the teeth portion thickness at the big end of drive bevel gear is M=58mm, and the end face of the drive bevel gear is fixedly connected with the axle；The driven wheel of differential, including driven wheel of differential inner cone, driven wheel of differential large end face, driven wheel of differential face cone, a diameter of D2=302.79mm of the driven wheel of differential, the thickness of driven wheel of differential is H=58.8mm.
The material of the drive bevel gear and driven wheel of differential is 22CrMoH.
The material of the drive bevel gear and driven wheel of differential is 22CrMoH.
The surface of the drive bevel gear has the first carburizcd case, the Available Hardened Depth DC values of first carburizcd case are 1.3mm~1.7mm, the surface of the driven wheel of differential has the second carburizcd case, and the Available Hardened Depth DC values of second carburizcd case are 1.2mm~1.6mm.
Beneficial effect：The present invention takes into account intensity and frock, the versatility of fixture of drive bevel gear and axle, the development cost of product is reduced as far as possible, bevel gear spline and gear shaft fracture when in use in existing heavy-duty truck main reducing gear bevel gear structure are effectively avoided, the service life of drive bevel gear and driven wheel of differential has been improved again.
Fig. 1 is drive bevel gear structural representation of the present invention；
Fig. 2 is driven wheel of differential structural representation of the present invention.
The invention will be further described with reference to the accompanying drawings and examples：
Referring to Fig. 1, Fig. 2, a kind of bevel gear structure of main reducing gear, including intermeshing drive bevel gear and driven wheel of differential, the drive bevel gear include the big end 1 of drive bevel gear, end face 2 and axle 3, it is characterised in that：A diameter of D1=230.5mm at the big end 1 of drive bevel gear, the teeth portion thickness at the big end 1 of drive bevel gear is M=58mm, and the end face 2 of the drive bevel gear is fixedly connected with the axle 3；The driven wheel of differential, including driven wheel of differential inner cone 10, driven wheel of differential inner 4 and driven wheel of differential face cone 11, a diameter of D2=302.79mm of the driven wheel of differential, the thickness of driven wheel of differential is H=58.8mm.The material of the drive bevel gear and driven wheel of differential is 22CrMoH.The surface of the drive bevel gear has the first carburizcd case, the Available Hardened Depth DC of first carburizcd case（Carburizing Depth, carburizing and quenching after-hardening layer depth）It is 1.3mm to be worth, and can also be 1.7mm or 1.5mm.The surface of the driven wheel of differential has the second carburizcd case, and the Available Hardened Depth DC values of second carburizcd case are 1.2mm, can also be 1.6mm or 1.4mm.Drive bevel gear and above-mentioned driven wheel of differential impulse- free robustness, without cutting edge of a knife or a sword side, due to carrying out strengthening design in the tooth form to drive bevel gear and driven wheel of differential, main optimal way is using special tooth depth coefficient, addendum coefficient and strength matching, only form of gear tooth argument section is redesigned, it is completely the same with product before strengthening design so as to remain part, ensure that frock during processing, fixture and measurer are completely general with product before design, without being further added by any other input, it is achieved thereby that inexpensive, high benefit, the new product innovation design idea of high added value.
