1、分析液压盘式传动装置的可靠性为了进一步提高制动器与液压传动装置的可靠性,增强监测功能是必要的。如果制动器和液压传动装置出现故障,特别是液压的残压以及油污染会导致电磁换向阀的卡住等,都会造成严重后果。Inordertofurtherimprovethereliabilityofbrakeandhydraulictransmissiondevice,enhancethemonitoringfunctionisnecessary.Ifthebrakeandhydraulictransmissiondevicefailure,esp

3、,盘式制动器包含不可维修因素,如制动弹簧失效之后,影响制动力矩,需要更换新弹簧才能使制动器可靠性达到原有水平;闸瓦与闸盘之间摩擦系数衰减,也只能靠更换新闸瓦方能维持原有可靠性水平。从广义可靠性理解,盘式制动器含有可维修因素,如闸瓦磨损后产生的间隙增大,经调整便可达到原有可靠性;液压站零件发生故障,修理后也能使制动器可靠性达到设计水平。由此可知,制动器的工作可靠性是固有可靠性和使用可靠性的综合反映。固有可靠性是由制动器设计制造及材料等因素决定的,在制动器产品出厂时便已明确,使用可靠性则是安装、维护及操作等因素决定的,它反映了制
4、动器固有可靠性在实际运行中的发挥程度,因此,固有可靠性的体现,受使用可靠性的限制,固有可靠性再高,使用可靠性却较低,制动器的实际工作可靠性依然不会高。Understandingfromthenarrowreliability,discbrakeincludesnotrepairfactors,suchasafterthebrakespringfailure,effectofbrakingtorque,theneedtoreplacethenewspringinordertomakethebrakereliabilityrea
