Rotary worktable

回转工作台

Abstract

The utility model discloses a novel rotary table, and mainly applies to rotation of a solar tracking device, and situations such as factory industrial equipment needing to be borne and rotate. The rotary table comprises an upper rotary table board, a lower fixed seat, a wheel carrier and a driving unit; the driving unit which comprises a motor, a speed reducer and a pinion is mounted on the upper rotary table board; the lower fixed seat is a circular ring shaped component with a hole at the center; and holes evenly distributed along the hole at the center are formed on two end surfaces close to the hole at the center; the centers of the distribution circles of the holes coincides with the rotation center of the lower fixed seat; pintles passing through the holes on the lower fixed seat are fixedly connected to the lower fixed seat; the pinion are meshed with the evenly distributed pintles; the wheel carrier is provided with two cylindrical journals; and axes of the two journals are vertical to each other; a first rolling wheel and a second rolling wheel are arranged on the journals; the upper rotary table is borne on the lower fixed seat through the first and the second rolling wheels mounted at the bottom of the rotary table, and rotate around the lower fixed seat; and the driving unit can further comprise the speed reducer. The novel rotary table replaces the prior large-diameter rotary bearing structure, and causes installation and adjustment to be easy; and furthermore, the cost is very low.
本实用新型公开了一种新型的回转台,主要应用于太阳能跟踪器的回转、工厂工装设备等需要承载并回转的场合,包括上回转台面、下固定座、轮架、驱动单元,驱动单元包括马达、减速机、小齿轮,驱动单元安装在上回转台面上,下固定座是一个圆环形零件,中间还设置有孔,靠近孔的两端面上设置有沿孔均布的孔,孔的分布圆中心与下固定座的回转中心重合,柱销穿过所述下固定座上的孔,固定连接在下固定座上,小齿轮与均布的柱销啮合。轮架设置有两轴线相垂直的外圆轴颈,轴颈上设置有第一滚轮、第二滚轮;上回转工作台通过安装在其底部的第一滚轮、第二滚轮支承在下固定座上,并围绕下固定座回转;驱动单元中还可包括减速机。本实用新型代替原来大直径回转支承结构,使得安装调试简单,成本极低。
