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 ,并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 relation between the machine efficiency and the speed ration are stadied for the two basic methods,inclined plane and lever,of speed changes.The result shows that the machine effciency of lever method is larger that of inclined plane method?
