立式双孔专用钻床传动系统设计 摘要 机床作为实体经济中元素。因此机床有着无语伦比的地位在国民经济中。随着经济的高速发展，市场对钻床的研发和发展提出了很高的要求，因此我们有必要对钻床进行进一步的研究。钻床在机械制造业有很大的影响，在工件的加工过程中，有很多工序都要用到钻床，而有一部分工件的工序又对钻床提出了更高的要求，这也使得我们对钻床进行更高技术的改造。 多轴箱的设计是为了保证动力的传输，以适应机床的加工，保证了加工符合要求的零件起了很大作用。 18世纪末，随着蒸汽时代的到来，动力源不仅仅依靠人类的体力，这使得钻床得到革命性的突破。21世纪的到来，实际市场对钻床再一次提出更高的要求，也使的钻床在时代的大背景下又将面临机遇与挑战。 传统的单作用钻床完全不能完成社会市场的需求。因此我们不得不研发高效率，高精度的钻床。双作用钻床他满足了市场的实际需求，并大大的缩短了传统钻床的加工时间。 双作用钻头钻床他的总体结构主要由电动机，减速箱，多轴箱等组成。电动机是整个钻床的动力来源，他支撑起整个系统的运转，起着至关重要的作用。减速箱是为了满足钻头的转速能够达到加工工件实际所需的转速，这对工件的加工是至关重要的。多轴箱是为了提高加工效率，由于传统钻床不能满足日益高速发展的市场的需求，所以在改进传统钻床的基础上我们提出双作用钻头同时钻孔，这也就引出多轴箱的设计。 整个设计书主要是从五个方面着手，连杆组合机床结构设计，多轴箱的设计、传动系统减速箱的设计、传动系统电机的选用。 关键词：减速器；电动机；多轴箱； Abstract Machi
