使回转

The topic is The design of the drilling machine fixture for Processing lathe shifting fort upper thread bottom hole, and lathe shifting fort located in the lathe speed institutions, mainly from the shift so that the spindle rotary movement of workers in accordance with the requirements of work, have the necessary speed and torque Role.

本课题是车床拨叉上螺纹底孔加工钻床夹具设计，而车床拨叉它位于车床变速机构中，主要起换档，使主轴回转运动按照工作者的要求工作，获得所需的速度和扭矩的作用。

With the traditional vertical layout of the single-motor compared to Shearer, Shearer will be the ranging-arm installed directly in the cutting of the shell, gear device exclusively on cutting Shell and planetary reducer, the abolition of the spiral bevel gears, gear box fixed, Rocker rotating sets of structures, their structure is simpler, more compact and higher reliability.

与传统的纵向布置的单电机采煤机相比，该采煤机将截割电机直接安装在截割部壳体内，齿轮减速装置全部集中在截割部壳体及行星减速器内，取消了螺旋伞齿轮、固定减速箱、摇臂回转套等结构，使其结构更简单、紧凑，可靠性更高。
