摘　　要：针对国内50tm型塔机的起升速度性能并不满足部颁标准JJ1-85的要求与速度档次少的原因与现状,我们设计并完成了一种变速电机加电磁摩擦离合器控制的变速器双变传动系统方案的调速卷扬机,解决了上述问题。经测试与考核证实,卷扬机的研究是成功的。本文着重介绍变速器传动设计计算方法,提出了摩擦离合器“油雨”式冷却润滑方式,并展示了其应用前景。The current 50tm tower cranes do not satisfy therequirements of the standard JJ 1-85,and have less load-lifting speedgrades and speed ferformance.To solve this problem,a variable-speedwinch is designed from a two-variable drive system,using a friction-clutches.Proved by tests and practical checkout,the research on thewinch is successful.In this paper,the design and calculation method ofthe trasmission drive system is emphatically introduced.An“oil-rain”and lubrication pattern for the friction-clutch is suggested,and theapplication prospect of the winch is showed.
