摘要
本文通过具体实例的设计计算对机床主传动采用直流主轴电动机——机械无级变速系统时,电动机调速特性的确定、机械传动机构变速级数、传动比和公比的选取以及无级变速系统如何满足机床传动系统的要求等,进行了分析讨论,并在此基础上给出设计计算的步骤,可供设计参考。
Considering the application of the DC spindle motor to the main drive of the machine tool,the writer made a detail analysis, through an example,of the choice of transmitting the ratio,the common ratio and the slewing steps.And a discussion was made about the determination of the speed regulating characteristics of the motor.
