Mouth 11 is set to " L " type, and bottom surface is slightly above the upper surface of the axial cylindrical roller 3 of YRT turntable bearings, and width is slightly less than U-shaped lack
The width of mouth 17, it is ensured that feeding bearing 9 is docked with the smooth of cranse 6, realizes radial direction cylindrical roller 5 and smoothly loads inner ring 1
The process of raceway；Aperture section internal diameter in cranse 6 completely fills external diameter during radial direction cylindrical roller 5 slightly larger than inner ring 1, limits and has filled
Enter the scope of activities of radial direction cylindrical roller 5, it is to avoid the radial direction cylindrical roller 5 for having been charged into inner ring 1 raceway drops and problem of misalignment
Generation.
Implement the assembly aids of YRT turntables bearing radial direction cylindrical roller 5 of the present invention, assembly method is as follows：
1）Sliding block 10 is placed in the holding tank 12 on main buckle 7, and is engaged with feeding slideway 14；
2）By certain amount（About inner ring 1 completely fills 1.5 times of radial roller quantity）Radial direction cylindrical roller 5 be placed on main buckle
In the bulk supply groove 13 of plate 7, with hand rubbing radius vector to cylindrical roller 5, until radial direction cylindrical roller 5 fitly " is lain " in bulk supply groove
In 13；
3）Secondary buckle 8 is covered on above-mentioned main buckle 7, as the feeding bearing 9 of radial direction cylindrical roller 5；
4）The feeding bearing 9 of radial direction cylindrical roller 5 is holded up, it is stand-by；
5）Cranse 6 is put on the guiding external diameter of inner ring 1, the U-shaped breach 17 of cranse 6 and the radial direction cylindrical roller 5
The positioning spigot 11 of feeding bearing 9 is docked so that radial direction cylindrical roller 5 passes through U-shaped breach 17 under the thrust of sliding block 10
Into in the raceway of inner ring 1, radial direction cylindrical roller 5 is under the fixation of step surface 18, raceway of the proper alignment in inner ring 1
In, push-and-pull sliding block 10 repeatedly, you can be rapidly completed the assembling process of radial direction cylindrical roller 5.
Device is assembled in the present embodiment when in use, under the thrust of sliding block 10, the radial direction cylinder in holding tank 12
Roller 5 is sequentially entered in the track groove of inner ring 1, is realized the batch of radial direction cylindrical roller 5, is rapidly loaded the track groove of inner ring 1
In, the time that radial direction cylindrical roller 5 loads the raceway of inner ring 1 is substantially reduced, the labor intensity of assembly crewman is reduced；Due to hoop
The inner radius of circle 6 is provided with step, limits the scope of activities for having been charged into radial direction cylindrical roller 5, it is to avoid traditional assembling process
Middle roller drops the generation of problem, it also avoid having been charged into roller and the possibility misplaced occurs, substantially increases production efficiency.
In the above-described embodiments, positioning seat is cranse, to adjust the corresponding footpath of anchor window by way of rotating coaxially
To track groove, in other embodiments, the positioning seat can also be that circumferentially guiding movement is assemblied in the bearing on inner ring, now
The radial direction track groove corresponding to anchor window can be changed by way of moving up dynamic positioning seat in inner ring.
In the above-described embodiments, accommodating chamber and feed chamber are single file passage, in other embodiments, the accommodating chamber and confession
Material chamber can also accommodate more than two radial direction cylindrical rollers side by side, or even accommodate single or multiple taper rollers.In addition, should
Feed chamber can also be removed, by way of radial roller directly is placed on into accommodating chamber, to realize the row of radial direction cylindrical roller
Row, accommodating chamber is even also removed, i.e., directly radial roller is placed on feeding slideway.
