Abstract
A slewing bearing assembly for a rear axle of a grader comprises an outer side O-shaped ring, a slewing bearing inner ring, an inner side O-shaped ring, framework oil seal, a countersunk head screw, a flange, and a slewing bearing outer ring. The slewing bearing outer ring is fixed onto a balance box through a bolt. A casing of a wheel-side reducer is fixed on the slewing bearing inner ring through a bolt. The slewing bearing inner ring is capable of rotating around the slewing bearing outer ring. The slewing bearing inner ring and the slewing bearing outer ring are sealed through the framework oil seal while other components are sealed through the O-shaped rings. The framework oil seal is protected by the countersunk head screw and the flange. The slewing bearing assembly improves the reliability of the rear axle.
Description
Technical field
The utility model relates to a kind of pivoting support assembly that is installed in road grader back axle wheel reduction gear and tandem-driving bogie junction.
Background technology
At present, what produce both at home and abroad that wheel reduction gear and the tandem-driving bogie junction of road grader back axle adopt is bracing frame and support sleeve, and bracing frame is welded on the tandem-driving bogie, and supporting sleeve embeds in the bracing frame.In the use, though in supporting sleeve, squeeze into butter, support sleeve still is easy to wear, and because bracing frame is non-removable weldment, has caused the difficulty of maintenance.
Summary of the invention
In order to improve the reliability of back axle, realize bracing frame and the non-maintaining property of support sleeve and the convenience of maintenance, the utility model provides a kind of road grader back axle to use the pivoting support assembly.
The purpose of the utility model is achieved in that this pivoting support assembly is made up of outside O type circle, pivoting support inner ring, inboard O type circle, outside framework oil seal, flathead screw, flange and pivoting support outer ring etc.Wherein bolt is passed through to tandem-driving bogie in the pivoting support outer ring; The wheel reduction gear shell is through being bolted on the pivoting support inner ring; The pivoting support inner ring can be rotated around the outer ring; Lean on skeleton oil seal between the pivoting support Internal and external cycle, all the other are by the sealing of O type circle, and wherein outside framework oil seal is fixed through flathead screw and flange.
The beneficial effect of the utility model is: this kind pivoting support unit construction easy accessibility, and easy-maintaining need not played butter during use, has realized non-maintaining property; This kind pivoting support assembly has the characteristic of rotation, has not only satisfied the characteristic of tandem-driving bogie swing but also not easy to wear; Static sealing makes that sealing is more reliable.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the structural representation of the utility model example.
Among the figure: 1. outside O type circle 2. pivoting support inner rings 3. inboard O type circle 4. outside framework oil seals 5. flathead screws 6. flanges 7. pivoting support outer rings
The specific embodiment
Bolted connection is passed through with tandem-driving bogie in pivoting support outer ring 7; By 1 sealing of outside O type circle; Pivoting support inner ring 2 passes through bolted connection with the wheel reduction gear shell; By inboard O type circle 3 sealings, pivoting support inner ring 2 seals through outside framework oil seal 4 with outer ring 7, and outside framework oil seal 4 is fixed through flathead screw 5 and flange 6.
Claims (3)
1. a road grader back axle is used the pivoting support assembly; It is characterized in that: seal by outside framework oil seal between the pivoting support Internal and external cycle; Outside framework oil seal is fixed through flathead screw and flange; The pivoting support inner ring can be rotated around the outer ring, thereby has realized characteristic readily removable, that seal and rotate.
2. a kind of road grader back axle according to claim 1 is used the pivoting support assembly, it is characterized in that: wherein bolt is passed through to tandem-driving bogie in the pivoting support outer ring.
3. a kind of road grader back axle according to claim 1 is used the pivoting support assembly, it is characterized in that: the pivoting support inner ring is fixed through bolt and wheel reduction gear shell.
