摘要
根据斜面及杠杆这两种基本的变速方式,讨论了机构的机械效率与其速比之间的关系,得出了采用杠杆方式变速较斜面方式变速可以获得较大的机械效率的结论.
The relations between the machine efficiency and the speed ratio are studied by the two basic speed change ways of inclined plane and lever.The result shows that the machine efficiency of lever method is larger that of inclined plane method.
