Between be provided with pad, the outer ring of the radial bearing is fixedly installed togather with the housing of the gearbox, the radial bearing
Outer ring on the outside of be provided with open.
Used as a kind of improvement, the open outside is provided with the guide part being obliquely installed.
Used as a kind of improvement, the radial bearing is cylinder roller bearing.
After employing above-mentioned technical proposal, the invention has the beneficial effects as follows：Fill because automatic gear-box is supported with output shaft
Put including the thrust bearing and radial bearing for setting gradually from inside to outside, the shell of the outer ring of the radial bearing and the gearbox
Body is fixedly installed togather, thus in assembling, the housing assembling of the outer ring of radial bearing and gearbox is integral, follow-up
During use, the abrasion of the housing of gearbox and the outer ring of radial bearing can be prevented effectively from；Simultaneously as the centripetal axle
It is provided with open on the outside of the outer ring held, gearbox in maintenance dismounting, tear open by roller, inner ring and the thrust bearing for making radial bearing
Under, consequently facilitating changing adjust pad.The automatic gear-box output shaft support device that the present invention is provided is by by radial bearing
Be designed to separate structure, be not only simple in structure, and solve the wear problem of gear box casing, meanwhile, solve again to
The assembly problem of heart bearing.
Because the open outside is provided with the guide part being obliquely installed, by the guide effect of guide part, centripetal axle is made
The retainer for holding and roller are smoothly in the outer ring of radial bearing.

Specific embodiment
In order that the objects, technical solutions and advantages of the present invention become more apparent, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only to explain the present invention, and
It is not used in the restriction present invention.
As Fig. 1 and Fig. 2 jointly shown in, a kind of automatic gear-box output shaft support device, including setting successively from inside to outside
The thrust bearing 1 put and radial bearing 2, it is preferred that radial bearing 2 is cylinder roller bearing, the blowout patche 11 of thrust bearing 1 is set with
In the end of output shaft 3, the seat ring 12 of thrust bearing 1 is arranged on the housing 4 of gearbox, seat ring 12 and the change of thrust bearing 1
