XJ550沙漠修井机分动箱的研制

Development of Transfer Case for XJ550 Desert Workover Rig

摘要: XJ550沙漠修井机分动箱是为沙漠工况而特别设计的，是在常规ZJ20钻机用的分动箱基础上开发的。其结构紧凑、传动可靠，可实现车上装置和车下底盘的单独驱动、车上装置中绞车和转盘的单独驱动和同时驱动，还可实现车下底盘后桥单独驱动或后桥与前桥的同时驱动，能很好地满足沙漠无道路条件下的行驶和现场钻修作业要求。

Abstract: The transfer case in XJ550 desert workover rig was especially designed for operation in the desert, and it was developed based on the transfer case in conventional ZJ20 drilling rig. Its structure was compact, transmission was reliable, it can be used for driving the equipment on truck and single drilling of chassis and as well as driving the drawworks and rotary respectively and driving both of them at the same time, also for driving the rear axle singly and driving the rear and front axles at the same time. It can meet the demands of travelling in road-free condition in desert and workover in the oilfields.
