Abstract
The utility model discloses a rotation supporting structure used on a rotary table, mainly comprising a ring-shaped convex rib, and a ring-shaped rolling slot. The upper portion of the convex rib is connected with a rotating disc, and the lower portion of the rolling slot is connected with a fixed disc. The rotation supporting structure used on a rotary table is characterized in that the rolling slot comprises an upper roller ring and a lower rolling ball ring, the upper roller ring comprises a big ring and a small ring, vertically arranged rollers are provided at the inner side of the big ring and the outer side of the small ring, there is a gap between the outer roller and the inner roller, the distance of the gap is equal to the width of the convex rib, the convex rib is arranged in the gap, the rolling ball ring comprises a ring-shaped seat and rolling balls, a ring-shaped arc groove is arranged in the ring-shaped seat, the radian of the vertical section of the ring-shaped arc groove is more than 180 DEG, the rolling balls are arranged side by side in the ring-shaped arc groove, the upper roller ring is fixedly connected to the lower rolling ball ring, and in the front projection the rolling balls are positioned in the gap. The rotation supporting structure used on a rotary table obtained from the utility model is not liable to be damaged, because the supporting force can be distributed on the whole rotating disc.
Description
Technical field
The utility model relates to a kind of rotational supporting structure, especially a kind of rotational supporting structure that uses on rotary plate table.
Background technology
Existingly mainly form by two bearings up and down and the axle that is connected between two bearings at the rotational supporting structure that uses on the rotary plate table, two bearings are separately positioned on the upper and lower price fixing of top rotary table up and down, and be positioned at the center of entire table, in order to rotate, need to stand away between top rotary table and following price fixing, such structure is left following problem:
Because the supporting-point of whole rotating disk is in center of turntable, because the rotating disk area is bigger, along with the variation of moment firmly reach supporting-point also can become very big small at the rotating disk edge, because rotating disk mostly is wooden structures, the strength of aforementioned transmission can make the junction of rotating disk and bearing damage, influence is normal to be used, and therefore is necessary to improve.
Summary of the invention
The purpose of this utility model is more even, the non-damageable rotational supporting structure that uses on rotary plate table of a kind of supporting force distribution that designs for the deficiency that solves above-mentioned technology.
The rotational supporting structure that on rotary plate table, uses that the utility model is designed, it mainly is made up of the convex tendon of annular and the slot rolling of annular, described convex tendon top connects rotating disk, described slot rolling bottom connects price fixing, it is characterized in that described slot rolling by on roll collars and following ball collar and form, rolling collars on described is made up of a big ring and a little ring, be provided with the roller that rolls of vertical setting in the outside of big inboard of encircling and little ring, inside and outside roll the space arranged between roller, the distance in space and convex tendon width equate that described convex tendon is arranged in this space; Described ball collar down is made up of ring-type seat and ball, is provided with a circular arc groove in the ring-type seat, and described circular arc groove longitudinal section radian is greater than 180 degree, and described ball is arranged side by side in this circular arc groove; Roll collars on described and be fixedly connected on down on the ball collar, in front projection, described ball is positioned at described space.
As preferably, roll collars on described and be fixedly connected on down on the ball collar by sunk screw.
As preferably, described ball collar down is a segmentation structure, is convenient to take apart when ball damages, and ball is changed.
The rotational supporting structure that on rotary plate table, uses of the utility model gained, by slot rolling convex tendon is supported, roll roller and ball and realize relatively rotating of convex tendon and slot rolling, because slot rolling is all cirque structure to convex tendon, so supporting force can be distributed on the whole rotating disk, therefore more be difficult for impairedly, make the desk longer service life.
Description of drawings
Fig. 1 is the vertical view of embodiment 1 convex tendon;
Fig. 2 is the vertical view of embodiment 1 slot rolling;
Fig. 3 is the sectional side elevation of embodiment 1 rotational supporting structure;
Among the figure: convex tendon 1, slot rolling 2, down ball collar 3, encircle 4 greatly, little ring 5, roll roller 6, ring-type seat 7, ball 8, sunk screw 9.
The specific embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
Embodiment 1:
As shown in Figure 1, the described rotational supporting structure that on rotary plate table, uses of present embodiment, it mainly is made up of the convex tendon 1 of annular and the slot rolling 2 of annular, described convex tendon 1 top connects rotating disk, described slot rolling 2 bottoms connect price fixing, described slot rolling 2 by on roll roller 6 ring and following ball collar 3 is formed, rolling roller 6 rings on described is made up of 4 and little rings 5 of a big ring, what be provided with vertical setting in the outside of the inboard of big ring 4 and little ring 5 rolls roller 6, inside and outside roll 6 on roller the space arranged, the distance in space and convex tendon 1 width equate that described convex tendon 1 is arranged in this space; Described ball collar 3 down is made up of ring-type seat 7 and ball 8, be provided with a circular arc groove in the ring-type seat 7, described circular arc groove longitudinal section radian is greater than 180 degree (can make ball 8 major parts be positioned at the circular arc groove and prevent that it from deviating from), and described ball is arranged side by side in this circular arc groove; Roll roller 6 rings on described and be fixedly connected on down on the ball collar 3 by sunk screw 9, in front projection, described ball is positioned at described space.The described rotational supporting structure that on rotary plate table, uses of present embodiment, support by 2 pairs of convex tendons 1 of slot rolling, roll relatively rotating of roller 6 and ball 8 realization convex tendons 1 and slot rolling 2, because 2 pairs of convex tendons 1 of slot rolling are all cirque structure, so supporting force can be distributed on the whole rotating disk, therefore more be difficult for impairedly, make the desk longer service life.
Wherein, described ball collar 3 down also can be segmentation structure, can link to each other by screw between segmentation structure, is convenient to take apart when ball 8 damages, and ball is changed.
Claims (3)
1. rotational supporting structure that on rotary plate table, uses, it mainly is made up of the convex tendon of annular and the slot rolling of annular, described convex tendon top connects rotating disk, described slot rolling bottom connects price fixing, it is characterized in that described slot rolling by on roll collars and following ball collar and form, rolling collars on described is made up of a big ring and a little ring, be provided with the roller that rolls of vertical setting in the outside of big inboard of encircling and little ring, inside and outside roll the space arranged between roller, the distance in space and convex tendon width equate that described convex tendon is arranged in this space; Described ball collar down is made up of ring-type seat and ball, is provided with a circular arc groove in the ring-type seat, and described circular arc groove longitudinal section radian is greater than 180 degree, and described ball is arranged side by side in this circular arc groove; Roll collars on described and be fixedly connected on down on the ball collar, in front projection, described ball is positioned at described space.
