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 utlity model has following beneficial effect:
1, eight of the utility model row's ball slideway devices 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 of the utility model row's ball slideway devices becomes I-shape construction, and with respect to other shapes, its bearing capacity is strong, and section modulus is bigger;
3, the utility model 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 utility model can be arranged the ball slideway devices with eight of the utility model easily through the setting of support and be fixed on different use occasions; 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 utility model, the application of many occasions.
Above-mentioned explanation only is the general introduction of the utility model technical scheme, in order more to know the technological means of understanding the utility model, and can implement according to the content of specification, below with the preferred embodiment of the utility model and conjunction with figs. specify as after.The specific embodiment of the utility model is provided by following examples and accompanying drawing thereof in detail.
