摘要
本文将现代设计方法中的优化技术与可靠性设计理论相结合,提出了钻机关键零件的可靠性优化设计方法。按照可靠性优化设计方法设计的产品,既能定量地回答产品在运行中的可靠性,又能使产品的功能参数获得优化解。
     对ZK-150型钻机而言,需要解决的问题比较多,经综合考虑,本文仅对钻机的关键零件的可靠性优化设计问题进行研究。在研究了机械可靠性优化设计基本理论和方法之后,分别分析了V型带传动、圆弧锥齿轮、液压卡盘碟型弹簧的可靠性优化设计,对其进行针对性的研究,并通过试验对设计结果进行检验。
     通过可靠性优化设计,使钻机的设计质量得到很大提高,所研制的ZK-150型钻机经性能检测和工业性试验证明:技术性能先进,机械运转可靠,为煤矿提供了又一先进设备,具有广阔的市场前景。
In this paper, the optimum technique and reliability design are connected together to bring up the method of reliability and optimization design of the gear change mechanism. According to this way, products designed that not only may educe measurable reliability of running, but also can acquire optimum result of the function parameters.
    In this dissertation, typical reliability and optimization subjects of the pivotal parts of type ZK-150 drilling machine are studied systematically. After canvassing the basic theories and methods of reliability and optimization design of the transmission system, analyze the designs of the V-belt transmission, arc cone gear and disk spring separately. It is propitious to raise efficiency, improve capability, increase reliability, and decrease cost and so on .
    Through the research on the reducer reliability and optimization design, the design quality of the drilling machine are improved greatly. It is proved that the type ZK-150 drilling machine capability is advanced and operation is reliable by examine and industrial test in coal mine. Another advanced equipment provided to users has wide application foreground.
