为了保证质量,提高工效,降低成本,在农机配件生产中,越来越多地使用了专用设备。用这些专用设备进行铣、镗、钻等加工,其工作循环大多数要求:快进——工进——快退。为了适应这种要求,我们设计了一种通用简易进给箱。它的特点是:结构简单,制造容易,工作可靠,维修方便。现介绍如下。一、进给箱的结构及工作原理它由壳体1,蜗轮蜗杆副2和3,齿轮副5和6、8和9、12和13,牙嵌离合器11及安全离合器7等组成。主轴14上的快速小齿轮12和慢速大齿轮6在轴
In order to ensure quality, improve work efficiency, reduce costs, in the production of agricultural machinery parts, more and more use of special equipment. With these special equipment for milling, boring, drilling and other processing, the working cycle most of the requirements: fast forward - work - rewind. In order to meet this requirement, we designed a universal simple feed box. Its features are: simple structure, easy to manufacture, reliable, easy maintenance. Now introduced as follows. First, the feed box structure and working principle It consists of the housing 1, worm gear 2 and 3, gear pairs 5 and 6, 8 and 9, 12 and 13, jaw clutch 11 and safety clutch 7 and other components. The fast pinion 12 and the slow gear 6 on the main shaft 14 are on the shaft
