Abstract
The utility model provides a bevel gear structure of a main speed reducer. The bevel gear structure comprises a driving bevel gear and a driven bevel gear which are meshed with each other, wherein the driving bevel gear comprises a driving bevel gear tooth part, an end surface and a shaft, the diameter D1 of a large end of the driving bevel gear is 230.5mm, the thickness M of the large end of the driving bevel gear is 58mm, and the large end surface of the driving bevel gear is fixedly connected with the shaft; and the driven bevel gear comprises an inner end of the driven bevel gear, a large end of the driven bevel gear and a face cone of the driven bevel gear, the diameter D2 of the driven bevel gear is 302.79mm, and the thickness H of the driven bevel gear is 58.8mm. According to the structure disclosed by the utility model, the intensity of the driving bevel gear and the shaft as well as the generality of a tool and a fixture are taken into account, the development cost of a product is reduced as much as possible, the breakage of a bevel gear spline and a gear shaft in the bevel gear structure of the main speed reducer of an existing heavy-duty truck is effectively avoided, and the service life of the driving bevel gear and the driven bevel gear is also prolonged.
Description
Technical field
The utility model relates to a kind of main reducing gear, relates in particular to a kind of bevel gear structure of automobile main reducer.
Background technique
Because large-scale truck is more and more, demand for the vehicle bridge main reducing gear also is increasing, the vehicle bridge main reducing gear is that automotive transmission reduces rotating speed, increase the critical piece of moment of torsion, usually the vehicle bridge main reducing gear comprises drive bevel gear and driven wheel of differential composition, drive bevel gear and driven wheel of differential are meshing with each other, the rotation of drive bevel gear drives the driven wheel of differential rotation and gets final product work, but driven wheel of differential at first ruptures often when work, and driving gear intensity also has affluence, but because follower damages in early days, driving wheel is also damaged thereupon, cause gear pair early failue, the life-span deficiency.
The model utility content
The technical problem that the utility model solves: provide a kind of bevel gear structure of main reducing gear, not only prolonged the working life of bevel gear, and reach the double effects of not only strengthening gear but also reducing noise.
For solving the problems of the technologies described above, the utility model provides a kind of bevel gear structure of main reducing gear, comprise intermeshing drive bevel gear and driven wheel of differential, described drive bevel gear comprises the big end of drive bevel gear, end face and axle, it is characterized in that: the diameter of the big end of described drive bevel gear is D1=230.5mm, the tooth portion thickness of the big end of drive bevel gear is M=58mm, and the end face of described drive bevel gear is fixedlyed connected with described axle; Described driven wheel of differential comprises driven wheel of differential inner cone, driven wheel of differential large end face, driven wheel of differential face cone, and the diameter of described driven wheel of differential is D2=302.79mm, and the thickness of driven wheel of differential is H=58.8mm.
The material of described drive bevel gear and driven wheel of differential is 22CrMoH.
The surface of described drive bevel gear has the first carburizing quench-hardened case, effective hardened-depth DC value of this first carburizing quench-hardened case is 1.3mm～1.7mm, the surface of described driven wheel of differential has the second carburizing quench-hardened case, and effective hardened-depth DC value of this second carburizing quench-hardened case is 1.2mm～1.6mm.
Beneficial effect: the utility model is taken into account the intensity of drive bevel gear and axle and the versatility of frock, anchor clamps, reduce the Products Development cost as much as possible, effectively avoided bevel gear spline and gear shaft fracture in use in the existing heavy truck main reducing gear bevel gear structure, arranged the working life of having improved drive bevel gear and driven wheel of differential again.
Description of drawings
Fig. 1 is the utility model drive bevel gear structural representation;
Fig. 2 is the utility model driven wheel of differential structural representation.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
Referring to Fig. 1, Fig. 2, a kind of bevel gear structure of main reducing gear, comprise intermeshing drive bevel gear and driven wheel of differential, described drive bevel gear comprises the big end 1 of drive bevel gear, end face 2 and axle 3, it is characterized in that: the diameter of the big end 1 of described drive bevel gear is D1=230.5mm, the tooth portion thickness of the big end 1 of drive bevel gear is M=58mm, and the end face 2 of described drive bevel gear is fixedlyed connected with described axle 3; Described driven wheel of differential comprises driven wheel of differential inner cone 10, driven wheel of differential inner 4 and driven wheel of differential face cone 11, and the diameter of described driven wheel of differential is D2=302.79mm, and the thickness of driven wheel of differential is H=58.8mm.The material of described drive bevel gear and driven wheel of differential is 22CrMoH.The surface of described drive bevel gear has the first carburizing quench-hardened case, effective hardened-depth DC(Carburizing Depth of this first carburizing quench-hardened case, carburizing and quenching after-hardening layer depth) value is for 1.3mm, can also be 1.7mm or 1.5mm.The surface of described driven wheel of differential has the second carburizing quench-hardened case, and effective hardened-depth DC value of this second carburizing quench-hardened case is 1.2mm, can also be 1.6mm or 1.4mm.Drive bevel gear and above-mentioned driven wheel of differential do not have burr, the Wu Feng limit, because the profile of tooth of drive bevel gear and driven wheel of differential is being strengthened design, main optimal way is to adopt special tooth depth coefficient, addendum coefficient and strength matching, only form of gear tooth argument section is redesigned, thereby it is in full accord with the product of strengthening before designing to have kept part, guaranteed to add the frock in man-hour, product before anchor clamps and measurer and the design is general fully, need not increase any other input again, thereby realize low cost, high benefit, the new product innovation design idea of high added value.
