水源钻、冻结钻等机型的变速箱组件是由变速箱和安装在其上的变速、分动、反正三个凸轮机构组成。在使用过程中,往往因分动凸轮箱拆卸后调整不利,无法合箱,影响开钻。个别机台停钻数天,甚至一周之多,其原因并非生产厂家设计、制造有误,而是维修人员对其性能不甚熟悉和拆卸疏忽所造成。 Water source drilling, freezing drill and other models of transmission components are installed by the gearbox and the gear shift, the split, anyway, three cam mechanism. In the course of using, it is often unfavorable to adjust the disassembly of the cam box after disassembly and can not fit the box, thus affecting the drilling. Individual machine parked a few days, or even more than a week, the reason is not the manufacturer design, manufacturing errors, but maintenance personnel are not familiar with their performance and disassembly caused by negligence.
