Abstract
The utility model discloses a BJ130 type main speed reducer comprising a speed reducer shell, wherein the lower end of the speed reducer shell is provided with two symmetrical differential carriers which are mounted through an M97*1.5mm adjusting nut; the differential carriers are matched with the speed reducer shell through a 32012 type conical roller bearing; each differential carrier is internally provided with a half axle gear with a 19-tooth internal spline; and the standard pitch diameter of the 19-tooth internal spline of the half axle gear is phi38mm. By adopting the structure, the main speed reducer can be used for not only reducing the bearing capabilities of a BJ130 rear axle and a front driving axle using the BJ130 main speed reducer, but also solving the problem that a half axle is easy to crack; and the BJ130 type main speed reducer is novel in structural design and is convenient to mount.
Description
Technical field
The utility model relates to a kind of auto parts machinery, particularly BJ130 type main reducing gear.
Background technique
The semiaxis phenomenon of rupture so bearing capacity is also limited, and in use also often occurs owing to being subjected to the restriction of differential gear spline size in forerunner's bridge of existing BJ130 back axle and use BJ130 main reducing gear.
The model utility content
In order to overcome above shortcomings part in prior art, the purpose of this utility model is to provide a kind of BJ130 main reducing gear, it has not only improved the BJ130 back axle and has used the bearing capacity of forerunner's bridge that BJ130 master subtracts, and has solved the easy breakage problem of semiaxis.
In order to reach above-mentioned purpose, the utility model adopts following concrete technological scheme: BJ130 type main reducing gear, comprise reducer shell, the lower end of described reducer shell is provided with the differential carrier of two symmetries, adjusting nut by M97 χ 1.5mm is installed, described differential carrier coordinates with reducer shell by the tapered roller bearing of 32012 models, and the differential gear of 19 tooth internal splines is housed in each differential carrier, and the standard pitch diameter of differential gear 19 tooth internal splines is φ 38mm.
Compared with prior art, the utlity model has following outstanding advantages and effect: owing to being provided with above structure, this main reducing gear has not only improved the BJ130 back axle and has used the bearing capacity of forerunner's bridge that BJ130 master subtracts, and solved the easy breakage problem of semiaxis, structural design is novel again, and is easy for installation.
Description of drawings
Fig. 1 is the structural representation of the utility model number;
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment
In order further to explain the technological scheme of the utility model number, come below by specific embodiment that the utility model is elaborated.
as shown in Figure 1, BJ130 type main reducing gear, comprise reducer shell 1, the lower end of described reducer shell 1 is provided with the differential carrier 4 of two symmetries, adjusting nut 2 by M97 χ 1.5mm is installed, described differential carrier 4 coordinates with reducer shell 1 by the tapered roller bearing 3 of 32012 models, the differential gear 5 of 19 tooth internal splines is housed in each differential carrier 4, the standard pitch diameter of differential gear 19 tooth internal splines is φ 38mm, not only improve the BJ130 back axle and used the bearing capacity of forerunner's bridge that BJ130 master subtracts, and solved the easy breakage problem of semiaxis, structural design is novel again, easy for installation.
It should be noted that at last: above embodiment is only in order to technological scheme that the utility model number is described and unrestricted, although with reference to preferred embodiment, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technological scheme of the utility model number, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the utility model number.
