For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention realizes through following technical scheme:
A kind of eight row's ball slideway devices; Comprise a housing, a center and an inside casing; Said center slidably is arranged on the said housing, and said inside casing slidably is arranged on the said center, and said housing becomes C shape structure with the cross section of said inside casing; The cross section shape of said center is like an I-shape construction; It comprises the first cross support portion that is positioned at said I-shape construction two ends and the second cross support portion that structure is identical, and a junction, connects through said connecting portion one between the said first cross support portion and the second cross support portion; The opening of said housing and said inside casing is oppositely arranged, and the said first cross support portion is arranged in the said housing, and the said second cross support portion is arranged in the said inside casing; Four angles of first, second cross support portion of said center are respectively first globoidal structure; Be respectively second globoidal structure on said housing and the inside casing with on the corresponding position of first globoidal structure of described first, second cross support portion; Constitute a ball orbit between described corresponding first globoidal structure and second globoidal structure, be provided with several balls in the said ball orbit.
Further; Also be respectively arranged with a ball retainer between said housing and inside casing and the said center; Said ball retainer is a tubular structure, and its cross section one-tenth C shape structure, and the opening of said ball retainer is with identical with the opening of its housing that matches and inside casing; The position that is positioned at said ball orbit on the said ball retainer offers several and dodges the hole, and described several balls lay respectively at described dodging in the hole.
Further, said housing is fixed on the support.
Compared with prior art, the present invention has following beneficial effect:
1, eight row's ball slideway devices of the present invention have realized that through the plurality of balls between internal and external frames and the center load balance of runner device is stressed; Slide steadily; About runner device can not occur or the phenomenon that teetertotters; Between internal and external frames and center, realized that through the ball on four jiaos of the cross support portions contact at stable 4 respectively specifically, guaranteed between internal and external frames and the center stressed steadily;
2, the cross section of the center of eight row's ball slideway devices of the present invention becomes I-shape construction, and with respect to other shapes, its bearing capacity is strong, and section modulus is bigger;
3, the present invention has guaranteed the effectively spacing of ball through being provided with of ball retainer, ball can not occur and tumble the phenomenon that is deposited in a place, has further guaranteed 4 stable contacts between internal and external frames and the center;
4, the present invention can be fixed on different use occasions with eight row's ball slideway devices of the present invention easily through the setting of support; Need not eight row's ball slideway devices are done any change; Just can install and fix, but guarantee the production of eight row's ball slideway device mass of the present invention, the application of many occasions.
Above-mentioned explanation only is the general introduction of technical scheme of the present invention, understands technological means of the present invention in order can more to know, and can implement according to the content of specification, below with preferred embodiment of the present invention and conjunction with figs. specify as after.The specific embodiment of the present invention is provided by following examples and accompanying drawing thereof in detail.
