摘　　要：针对螺旋式摆动液压缸密封困难,制造成本高等问题,结合单活塞式双作用液压缸和滚珠丝杆副的传动特点,设计了一种基于滚珠丝杆副的新型摆动液压缸,分析了其结构原理,给出了输出扭矩和摆角计算公式。新型摆动液压缸利用滚珠丝杆的传动可逆性将活塞杆的推力直接转化为扭矩输出,结构简单紧凑,传动效率高,响应迅速,输出摆角范围大,与现有同类装置相比,密封性能好,设计制造成本低,可以实现数字化精确控制,为智能制造时代摆动执行机构的数字化、智能化设计与控制提供了一种思路。To solve the problems of difficult sealing and high manufacturing cost of spiral swing hydraulic cylinder and so on,make full use of the characteristics of single piston double-acting hydraulic cylinder and ball screw pair transmission to design a new type of swing hydraulic cylinder based on ball screw pair.Working mechanism is analyzed and calculation formula of output torque and swing angle is deduced.The new swing hydraulic cylinder uses the transmission reversibility of ball screw to directly convert the thrust of piston rod into torque output.It has advantages of simple and compact structure,high transmission efficiency,rapid response,and large output swing angle range.It is found that the new swing hydraulic cylinder has good sealing performance,low design and manufacturing cost,and can realize digital and accurate control compared with the existing similar devices.The development of swing hydraulic cylinder provides a reference for the digital and accurate control of swing actuator in the era of intelligent manufacturing Intelligent design and control provides a way of thinking.
