Abstract
The utility model discloses a rolling ball mounting structure of a linear guide rail. The rolling ball mounting structure comprises a guide rail body and a sliding block body, wherein rolling balls are mounted between the guide rail body and the sliding block body, the sliding block body is provided with arc-shaped concave faces, first grooves are formed in the center parts of the arc-shaped concave faces, the guide rail body is provided with four columns of arc-shaped rolling faces, and second grooves are formed in the center parts of the arc-shaped rolling faces. According to the rolling ball mounting structure of the linear guide rail, in an ideal two-point-contact structure, the four columns of arc-shaped rolling faces all have appropriate contact angles; and in the structure, due to the elastic deformation of steel balls and the movement of contact points, even if a mounting face has little deformation, the deformation can be absorbed in a sliding block, so that natural and smooth motion is realized. Thus, a field for mounting equipment has no need of a firm mounting base with high rigidity and high precision; and with the adoption of the two-point-contact structure, even if relatively large pre-compression is applied, the resistance can not be increased abnormally, and higher rigidity can be obtained.
Description
Technical field
The utility model relates to a kind of ball mounting structure of linear rail, belongs to the technical field of linear rail equipment.
Background technique
Guide rail in the machine intimate operation because friction factor is higher, load weight is large, the guide rail rigidity is inadequate, meeting loss guide rail, thereby reduce the working life of guide rail, cause whole guide rail cisco unity malfunction, guide rail connects by ball with slide block, the mounting structure of ball is most important, and is very large on the overall performance impact of guide rail and slide block.
The model utility content
The technical problem that (one) will solve
The technical problems to be solved in the utility model is to provide a kind of ball mounting structure of linear rail, has solved existing linear rail low problem in working life.
(2) technological scheme
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of ball mounting structure of linear rail, comprise guide rail body and slide block body, described ball is installed between described guide rail body and slide block body, described slide block body is provided with the circular arc concave surface, described circular arc concave surface central part is provided with the first groove, and described guide rail body is provided with the circular arc rolling surface, and described circular arc rolling surface central part is provided with the second groove.
The radius of curvature size of described circular arc concave surface and circular arc rolling surface is identical, and the radius of curvature of circular arc concave surface is 2 times of ball.
(3) beneficial effect
The utility model is compared and prior art, and it has following beneficial effect: linear rail is in 2 desirable contact structures, and 4 row circular arc rolling surfaces all have suitable wrapping angle; Under this structure, due to the resiliently deformable of steel ball and the movement of point of contact, even so attachment face have a small amount of distortion also can be absorbed in slide block, thereby yet realize from level and smooth motion.Like this,, for the place of erection unit, just need not high rigidity, high-precision firm mounting base; Under 2 contact structures, even apply relatively large precompressed, resistance can't increase extremely, can obtain higher rigidity.
Description of drawings
Fig. 1 is the structural representation of ball mounting structure of a kind of linear rail of the utility model embodiment.
Fig. 2 is the detailed structure view of the ball mounting structure in Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
As depicted in figs. 1 and 2, a kind of ball mounting structure of linear rail, comprise guide rail body 2 and slide block body 1, described ball 3 is installed between described guide rail body 2 and slide block body 1, described slide block body 1 is provided with circular arc concave surface 5, described circular arc concave surface 5 central parts are provided with the first groove 6, and described guide rail body 2 is provided with circular arc rolling surface 4, and described circular arc rolling surface 4 central parts are provided with the second groove 7.
The radius of curvature size of described circular arc concave surface 5 and circular arc rolling surface 4 is identical, and the radius of curvature of circular arc concave surface 5 is 2 times of ball 3.
The first groove and the second groove are oil storage tank, need not extra fuel feeding, have guaranteed the fluency that ball rolls.
The slide block structure of linear rail is 2 contact structures of 4 row arc groove, 2 and trench contact are arranged on load direction due to ball, as shown in Figure 2, even having in precompressed or normal duty situation, difference between d1 and d2 is less, therefore the differential sliding amount can reduce, thereby realizes level and smooth rolling motion.
In 2 desirable contact structures, 4 row circular arc rolling surfaces all have suitable wrapping angle.Under this structure, due to the resiliently deformable of steel ball and the movement of point of contact, even so attachment face have a small amount of distortion also can be absorbed in slide block, thereby yet realize from level and smooth motion.Like this,, for the place of erection unit, just need not high rigidity, high-precision firm mounting base.
Under 2 contact structures, even apply relatively large precompressed, resistance can't increase extremely, can obtain higher rigidity.
, because the radius of curvature of steel ball rolling face is 50% of steel ball radius, therefore can reach larger rated load.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
