Abstract
The utility model discloses a kind of automatic transmission case separated type radial bearing, belong to automatic transmission case technical field, comprise outer ring, roller, retainer and the inner ring for the output shaft that is set with described gearbox, the side of described outer ring is provided with rib, the opposite side of described outer ring is provided with uncovered, and the housing of described outer ring and described gearbox is fixedly installed togather.The utility model, by radial bearing is designed to separate type, not only solves the wear problem of gear box casing, solves the assembly problem of radial bearing simultaneously.
Description
Technical field
The utility model belongs to automatic transmission case technical field, particularly relates to a kind of automatic transmission case separated type radial bearing.
Background technique
Output shaft one end connected row carrier of automatic transmission case, the other end is installed on gear box casing by support device, and output shaft is provided with the shaft shoulder and output gear from inside to outside successively.Support device comprises bearing, bearing comprises the roller bearing for mainly bearing radial force and the thrust bearing for mainly bearing axial force, roller bearing is installed on the shaft shoulder, be provided with pad between the outer ring of roller bearing and gear box casing, thrust bearing is in the end of output shaft and be provided with adjustment pad between thrust bearing and gear box casing.
At present, because gearbox is when overhauling, need need to change suitable adjustment pad according to size, because adjustment pad is positioned at inner side, for the ease of assembling and dismounting, the outer ring of roller bearing and gear box casing are Spielpassung.But, in running, easily cause gear box casing outer ring to wear and tear, after permanent use, the damage of other component of gearbox can be caused.
Model utility content
Technical problem to be solved in the utility model is: provide a kind of automatic transmission case separated type radial bearing, the technical problem causing gear box casing outer ring to be worn and torn with the outer ring and gear box casing Spielpassung that solve existing roller bearing.
For solving the problems of the technologies described above, the technical solution of the utility model is: automatic transmission case separated type radial bearing, comprise outer ring, roller, retainer and the inner ring for the output shaft that is set with described gearbox, the side of described outer ring is provided with rib, the opposite side of described outer ring is provided with uncovered, and the housing of described outer ring and described gearbox is fixedly installed togather.
Improve as one, the described uncovered side deviating from described rib is provided with the guide portion be obliquely installed.
Improve as one, described roller is cylindrical roller.
After have employed technique scheme, the beneficial effects of the utility model are: because automatic transmission case separated type radial bearing comprises outer ring, roller, retainer and inner ring, the side of described outer ring is provided with rib, the opposite side of described outer ring is provided with uncovered, the housing of described outer ring and described gearbox is fixedly installed togather, thus when assembling, the housing of outer ring and gearbox is assembled into one, simultaneously, rib is made to be positioned at the inner side of gear box casing, in follow-up using process, effectively can avoid the housing of gearbox and the wearing and tearing of outer ring; Meanwhile, uncovered due to described outer ring devising, gearbox, when overhauling dismounting, makes roller and inner ring pull down, thus is convenient to change adjustment pad.The automatic transmission case separated type radial bearing that the utility model provides adopts separate type, and not only structure is simple, and solves the wear problem of gear box casing, meanwhile, solves again the assembly problem of radial bearing.
Because the described uncovered side deviating from described rib is provided with the guide portion be obliquely installed, by the leading role of guide portion, when assembling, retainer and roller are entered in outer ring smoothly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is using state schematic diagram of the present utility model;
In figure: 1, outer ring, 11, rib, 12, uncovered, 121, guide portion, 2, roller, 3, retainer, 4, inner ring, 5, output shaft, 51, the shaft shoulder, 52, output gear, 6, housing, 7, thrust bearing, 71, blowout patche, 72, seat ring, 8, adjustment pad, 9, pad.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As Fig. 1 and Fig. 2 jointly shown in, a kind of automatic transmission case separated type radial bearing, comprise outer ring 1, roller 2, retainer 3 and the inner ring 4 for the output shaft 5 that is set with gearbox, roller 2 is preferably cylindrical roller, the side of outer ring 1 is provided with rib 11, the opposite side of outer ring 1 is provided with uncovered 12, and outer ring 1 is fixedly installed togather with the housing 6 of gearbox.
When assembling, in order to make retainer 3 and roller 2 enter in outer ring 1 smoothly, uncovered 12 sides deviating from rib 11 are provided with the guide portion 121 be obliquely installed, and guide portion 121 pairs of retainers 3 and roller 2 play the guiding role.
Below for the supporting structure of automatic transmission case output shaft, introduce working principle of the present utility model in detail.
As shown in Figure 2, the supporting structure of automatic transmission case output shaft comprises above-mentioned separated type radial bearing and thrust bearing 7, the blowout patche 71 of thrust bearing 7 is set in the end of output shaft 5, the seat ring 72 of thrust bearing 7 is arranged on the housing 6 of gearbox, is provided with and adjusts pad 8 between the seat ring 72 of thrust bearing 7 and the housing 6 of gearbox; Inner ring 4 is sleeved on the shaft shoulder 51 of output shaft 5, the outside of inner ring 4 and the output gear 52 of output shaft 5 lean, the inner side of inner ring 4 and the blowout patche 71 of thrust bearing 7 lean, when assembling, the housing 6 of outer ring 1 and gearbox is fixed together, preferably, interference fit is adopted between the housing 6 of outer ring 1 and gearbox, meanwhile, make rib 11 be positioned at the inner side of the housing 6 of gearbox, between the housing 6 of rib 11 and gearbox, be provided with pad 9.
Because the housing 6 of outer ring 1 and gearbox is fixed together, in follow-up using process, effectively can avoid the housing 6 of gearbox and the wearing and tearing of outer ring 1; Meanwhile, due to outer ring 1 devising uncovered 12, gearbox, when overhauling dismounting, makes roller 2 and inner ring 4 pull down, thus is convenient to change adjustment pad 8.
The automatic transmission case separated type radial bearing that the utility model provides adopts separate type, and not only structure is simple, and solves the wear problem of gear box casing, meanwhile, solves again the assembly problem of radial bearing.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
