The invention discloses a rotary push-pull folding vertical lifting device which is provided with an eccentric transmission structure, the eccentric transmission structure comprises an inner wheel, a bearing and an outer wheel, the inner wheel is provided with an eccentric hole, a driving shaft of a driving device is assembled in the eccentric hole and drives the inner wheel to rotate around the eccentric hole, the bearing is arranged between the outer wheel and the inner wheel, and the outer wheel drives a rotating arm to rotate; wherein the bearing comprises two flange plates, a plurality of cylindrical rolling shafts and a connecting piece, the two flange plates are fixedly connected through the connecting piece, the two ends of each rolling shaft are rotatably installed on the flange plates on the same side respectively, balls are arranged at the end portions of the two ends of each rolling shaft, and the balls protrude out of the end faces of the end portions of the rolling shafts. Most bearings in the prior art are of concentric circle structures and only play a role in reducing friction, while the eccentric hole is used for achieving transmission of the eccentric transmission structure and reducing friction at the same time, remarkable progress is achieved, abrasion between the inner wheel and the outer wheel and abrasion between the inner wheel and the flange plate are reduced, and the service life of equipment is prolonged.

    本发明公开了一种旋转推拉折叠竖直升降装置,其设置偏心传动结构,偏心传动结构包括有内轮、轴承和外轮,内轮设置有偏心孔,驱动装置的驱动轴装配于偏心孔并驱动内轮绕偏心孔转动,轴承设置于外轮和内轮之间,外轮带动旋转臂旋转;其中,轴承包括有两张法兰板、多个圆柱形滚轴和连接件,两张法兰板通过连接件固定连接,滚轴的两端分别可转动地安装于同侧的法兰板且滚轴的两端端部设置有滚珠,滚珠凸出于滚轴端部的端面。现有技术的轴承多数为同心圆结构仅起到减少摩擦的作用,而本发明利用偏心孔实现偏心传动结构在传动的同时降低摩擦,具有显著的进步,并且减少内轮与外轮及法兰板之间的磨损延长设备使用寿命。
