上海拖拉机厂为了适应本厂产品加工的需要,遵照毛主席“独立自主、自力更生”的伟大教导,创制了一种中型机械动力头。图1是这种动力头的外观。它的结构简单,体积小,制造维修方便,成本低。该厂成批生产,组装成很多台高效率的组合机床。对生产工农—7型手扶拖拉机起了很大作用。这种动力头适合中小厂加工工艺简单、工序少的工件。动力头的内部机构如图2所示,传动系统见图3。
Shanghai tractor factory in order to adapt to the needs of our products processing, in accordance with Chairman Mao “independent, self-reliance,” the great teaching, created a medium-sized mechanical power head. Figure 1 shows the appearance of this power head. Its structure is simple, small size, easy manufacture and maintenance, low cost. The factory mass production, assembled into many high-efficiency combination of machine tools. On the production of worker-peasant -7 type tractor has played a significant role. This power head for small and medium-sized factory processing technology is simple, less workpieces. Power head of the internal body shown in Figure 2, the transmission system shown in Figure 3.
