The utility model discloses an all-terrain axle transmission sealing structure which comprises an output shaft and universal joints, wherein the output shaft is matched with a shell through bearings; the bearings are positioned on the shell; the output shaft is axially positioned through the bearings; the universal joints are connected with the output shaft through splines and are axially positioned through nuts fastened on the output shaft; oil seals are mounted between the bearings and the universal joints in holes in the shell; a shaft sleeve is also arranged between each of the bearings and each of the universal joints; outer rings of the shaft sleeves are matched with lips of the oil seals; annular grooves are formed in inner holes of the shaft sleeves; sealing rings are placed in the annular grooves; the shaft sleeves are matched with the output shaft through the sealing rings; two ends of the shaft sleeves are axially positioned through the bearings and the universal joints respectively. The shaft sleeves are additionally arranged between the bearings and the universal joints, so that matching between the universal joints and the oil seals is eliminated, and the difficulty in processing of outer circular surfaces of the universal joints is lowered; therefore, the spline connection parts between the universal joints and the output shaft are positioned in an oil-free region outside the shaft sleeves, so that the processing difficulty and the manufacturing technology for the universal joints and the splines of the output shaft are lowered, and sealing is more reliable.
Description
Technical field
The utility model relates to shaft drive sealing configuration, is specifically related to a kind of shaft drive sealing configuration for all-terrain vehicle.
Background technique
In prior art, the shaft drive sealing configuration of all-terrain vehicle as shown in Figure 1, gimbal joints is connected with output shaft by spline, gimbal joints outer ring coordinates with oil seal lip, the lubricant oil that sealing is flowed out through bearing, adopting the shortcoming of said structure is for preventing leakage of oil, must guarantee that the circumference of gimbal joints and oil sealing fitting surface beats, and the degree of finish of the periphery that gimbal joints is coordinated with oil seal lip proposed very high requirement, difficulty of processing increases.
Gimbal joints and output shaft adopt spline joint, can cause the defects such as the spline manufacturing cost of output shaft and gimbal joints increases, and technique is manufactured complicated, and difficulty is large.In addition the sealing at universal joint and output shaft spline fitted place be by universal joint end face and bearing face coordinate realize, also very high to the perpendicularity requirement on machining accuracy of gimbal joints end face and splined hole.
Model utility content
Technical problem to be solved in the utility model is, provide a kind of simple in structure, the shaft drive sealing configuration that is easy to processing and installs, by increase axle sleeve between bearing and universal joint, axle sleeve is coordinated with oil seal lip, cancellation universal joint coordinates with oil sealing, has reduced the difficulty of processing of universal joint periphery.Simultaneously spline joint Wu You district outside axle sleeve of gimbal joints and output shaft, has also reduced difficulty of processing and the manufacturing process of universal joint and output shaft spline, seals more reliable.
For solving above-mentioned technical problem, the utility model has been taked following technological scheme: a kind of all-terrain vehicle shaft drive sealing configuration, comprise stepped output shaft and universal joint, and output shaft coordinates with housing by bearing, bearing is positioned on housing, and output shaft is by bearing axially locating; Described universal joint is connected with output shaft by spline, and by the nut axially locating being fastened on output shaft; Between bearing and universal joint, in housing bore, oil sealing is installed, between described bearing and universal joint, be also provided with an axle sleeve, described axle sleeve outer ring coordinates with oil seal lip, inner hole of shaft sleeve is provided with annular groove, seal ring is placed in annular groove, axle sleeve coordinates with output shaft by seal ring, and axle sleeve two ends are respectively by bearing and universal joint axially locating.
Described seal ring is O shape circle.
Described universal joint spline endoporus and output shaft spline joint place are provided with chamfering.
Annular groove diameter on described inner hole of shaft sleeve is greater than the diameter of the output shaft coordinating with inner hole of shaft sleeve.
The beneficial effect that the utility model can reach is:
1, sleeve outer circle face and oil seal lip fitted seal, the coaxality conformity of inner hole of shaft sleeve and periphery easily guarantees, the matching gap of inner hole of shaft sleeve and output shaft easily guarantees, has avoided the poor leakage of oil causing of former universal joint spline endoporus and periphery coaxality conformity.
2, inner hole of shaft sleeve coordinates with output shaft, in endoporus annular groove, seal ring is set, the lubricant oil flowing out between energy stuffing box bearing endoporus and output shaft, and the lubricant oil flowing out between axle sleeve and bearing fit end face, make the spline joint of output shaft and universal joint outside sealing area, reduced the coaxality requirement of gimbal joints periphery and spline endoporus and the difficulty of processing of universal joint spline endoporus and output shaft spline, the degree of finish of universal joint periphery requires also corresponding reduction.
3, axle sleeve and output shaft coordinate compared with universal joint and output shaft spline fitted simply easy.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details.
The utility model in the specific implementation, as shown in Figures 2 to 4, a kind of all-terrain vehicle shaft drive sealing configuration, comprise stepped output shaft 5 and universal joint 6, output shaft 5 coordinates with housing 7 by bearing 1, and bearing 1 is positioned on housing 7, and output shaft 5 is by bearing 1 axially locating.Universal joint 6 is connected with output shaft 5 by spline, and by the nut 9 and pad 10 axially locating that are fastened on output shaft 5; Between bearing 1 and universal joint 6, housing is provided with oil sealing 3 in 7 holes, is also provided with an axle sleeve 4 between bearing 1 and universal joint 6, axle sleeve 4 outer rings coordinate with oil sealing 3 lips, the lubricant oil that sealing is flowed out through bearing 1.Axle sleeve 4 endoporus are provided with annular groove 8, an O-ring seals is placed in annular groove 8, the diameter of annular groove 8 is greater than the diameter of the output shaft 5 coordinating with axle sleeve 4 endoporus, axle sleeve 4 coordinates with output shaft 5 by O-ring seals 2, the lubricant oil flowing out between stuffing box bearing 1 endoporus and output shaft 5, and the lubricant oil flowing out between axle sleeve 4 and bearing 1 counterface.Axle sleeve 4 two ends are respectively by bearing 1 and universal joint 6 axially locating.
The installation process of above-mentioned part is as follows:
1, bearing 1 is installed in the hole of housing 7, by housing 7 step location, oil sealing 3 is assemblied in housing 7 holes, output shaft 5 is arranged in bearing 1 hole, and by bearing 1 axially locating;
2, pack axle sleeve 4 into output shaft 5, make axle sleeve 4 near bearing 1 and outer ring and oil sealing 3 lips cooperations;
