摘要 本设计从下达任务起，经过现场调查和查阅文献资料入手，历经三个月的时间完成。在设计中，首先根据课题所要求的技术参数确定机床设计中所需要的参数，即原动机的功率、机床主轴箱的转速数列公比；然后确定机床主轴箱的主传动系统结构，拟订机床的结构网和转速图；查资料，根据转速图确定机床内的各个主要零件的计算转速，根据计算转速确定各级传动的传动比，根据传动比来确定各级传动的齿轮配合的齿轮齿数。根据机床主轴箱的传动链来计算各级转速的实际值与理论值之间的误差。在设计中主要是要计算主轴箱里各个零件的选用是否满足要求以及原动机与主轴箱间的动力传递装置的计算。主轴箱的计算包括摩擦离合器的校核、齿轮的校核、轴的校核、轴承的校核、键的校核、主轴的校核计算等。原动机与主轴箱的动力传递采用的是带传动装置。最后根据资料和参考同类机床来设计计算机床的电气和液压系统，并绘制其原理图。 关键词：转速数列；公比；结构网；转速图；计算转速；转速数列公比。 ABSTRACT This desig
