Abstract
The utility model discloses a final drive shell for a rear axle of a heavy-duty truck, which comprises a driving axle housing and bearing blocks, wherein the bearing blocks are arranged at the end part of the driving axle housing, one of the bearing blocks is integrated, moreover, retaining steps are arranged in the cavity of the bearing block, the function of the retaining steps is to retain a tapered roller bearing, adjusting shims are arranged between the retaining steps and the tapered roller bearing, and the function of the adjusting shim is to adjust the gap between the bearing block and the tapered roller bearing. The utility model effectively overcomes the defect that the nuts for fixing the bearing block of the conventional final drive can easily come off, thus prolonging the service life of equipment and reducing the maintenance cost of equipment.
Description
Technical field
The utility model relates to a kind of final drive casing of heavy-duty car back axle, specifically a kind of housing that is used for the main reducing gear of heavy-duty car ransaxle.
Background technique
The effect of the main reducing gear of heavy-duty car ransaxle is to reduce the rotating speed that transmits from main drive shaft, thereby increase moment of torsion and change power direction, its drive part is made up of a pair of intermeshing basin corner gear, power passes to the basin tooth flank of tooth by the angle tooth flank of tooth, reached transmission power simultaneously, change the purpose of power direction and deceleration, as shown in Figures 1 to 3, bearing support on traditional final drive casing driving axle housing is divided into two-part up and down, and connect by bolt, fix and the adjustment tapered roller bearing, have a big nut to finish, the basin tooth flank of tooth and the angle tooth flank of tooth are to be oblique arcuation, when power passes through meshed transmission gear, can produce horizontal impact force; During the moment increase of angle tooth moment, can produce bigger impact force to the basin tooth, these lateral impact forces interlock basin tooth tapered roller bearings, the bearing shell is adjusted big nut to external impact, and frustrates, becomes flexible to coming off.Tooth fulcrum disequilibrium in basin angle is just broken basin angle tooth to power transmission and is ended.Can not work until whole retarder, vehicle is forced to stop.
The model utility content
The purpose of this utility model provides a kind of final drive casing of heavy-duty car back axle, is particularly useful for the main reducing gear of heavy-duty car ransaxle, has prolonged the working life of equipment effectively, has reduced the maintenance cost of equipment.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of final drive casing of heavy-duty car back axle comprises driving axle housing and bearing support, and bearing support is located at the end of driving axle housing, and wherein the bearing support of a side is made as one, and is provided with in its cavity and stops step.The effect that stops step is to be used to stop fixedly tapered roller bearing.
Stop to be provided with the adjustment pad between step and the tapered roller bearing that the effect of adjusting pad is the gap of adjusting bearing support and tapered roller bearing.
The beneficial effects of the utility model are:
The utility model has overcome traditional main reducing gear effectively to be made the nut of fixed bearing block easily and stops the drawback that the big nut of tapered roller bearing comes off, thereby has prolonged the working life of equipment, has reduced mechanical maintenance cost.

Among the figure: 1, upper bearing bracket; 2, step; 3, driving axle housing; 4, bolt; 5, bearing support; 6, adjust pad; 7, tapered roller bearing; 8, stop step; 9, nut.
Embodiment
As shown in Figs. 4-6, a kind of final drive casing of heavy-duty car back axle comprises driving axle housing 3 and bearing support 5, and bearing support 5 is located at the end of driving axle housing 3, and wherein the bearing support 5 of a side is made as one, and is provided with in its cavity and stops step 8.The effect that stops step 8 is to be used to stop fixedly tapered roller bearing 7.Traditional final drive casing as shown in Figures 1 to 3, its bearing support 5 is divided into upper bearing bracket 1 and step 2, both connect by bolt 4, equipment is in operation process like this, the impact force of intermittent variation is easy to make bolt 4 and nut 9 to come off.
Stop to be provided with between step 8 and the tapered roller bearing 7 and adjust pad 6, the effect of adjusting pad 6 is the gap of adjusting bearing support 5 and tapered roller bearing 7, makes equipment reach desirable working state.
As preferably: the height 8mm of step; Wide 10mm;
Adjust the external diameter 140mm of pad; Internal diameter 120mm; Thickness specification: 1.0mm/0.5mm/0.2mm/0.1mm.
