摘　　要：针对现有液压缸产品性能单一、运动模式较少、日益不能满足现代工业自动化生产的要求等问题,设计了一种新型旋转直线组合式液压缸。该液压缸利用滚珠花键副能传递扭矩和实现直线运动的特点,将双螺旋摆动液压缸与传统往复直线式液压缸有机结合,不仅可以实现单一的往复直线运动和旋转运动,也可以实现复杂的旋转直线复合运动,技术功能完善,结构紧凑,安装方便,能够满足市场对液压传动产品性能多样化的需求。The existing fluid power products with single property and less motion patterns can not meet requirements of the modern industrial automation production day by day. For this problem,We design a new rotary motion and linear motion combined hydraulic cylinder. The new hydraulic cylinder uses the features of ball spline pair can transfer torque and realize linear motion to integrate double screw pair of rotary and traditional reciprocating linear motion hydraulic cylinder,not only can realize single reciprocating linear motion and rotary motion,but also complicated rotary motion and linear motion combined movement. It is of good technical performance,compact- sized,easy installation,and can satisfy the market＇s demands for hydraulic transmission products with various properties.
