自多绳摩擦式提升机问世,40余年来有了很大发展。主要表现在以下三点:1、结构及性能更加完备;2、在近一二十年设计的大型竖井提升系统中多绳摩擦式提升机得到进一步广泛的应用;3、根据采煤、采矿业的要求,多绳摩擦式提升机必须向大型发展。要求我们设计制造的产品必须安全可靠、经济耐用。因此对产品一些零部件的强度、刚度进行深入的分析和研究是非常有意义的实际问题, 主导轮是多绳摩擦式提升机的主要承载部
Since the advent of multi-rope friction hoist, more than 40 years have made great progress. Mainly in the following three points: 1, the structure and performance more complete; 2, in the last decade or two decades designed large shaft hoisting system multi-rope friction hoist has been further widely used; 3, according to mining, mining The requirements of multi-rope friction hoist must be large-scale development. Require us to design and manufacture of products must be safe and reliable, economical and durable. Therefore, some parts of the product strength, stiffness in-depth analysis and research is a very meaningful practical problem, the main wheel is the main bearing of multi-rope friction hoist
