中文摘要:
      建立了螺旋齿摆动液压缸的两级螺旋副动力学数学模型,采用ADAMS仿真软件对其进行动力学分析,研究其在极限外负载条件下的最大角度及输出扭矩;依据建立的动力学模型,对螺旋副关键参数进行了优化,分析了不同螺旋升角对两级传动副输出性能的影响。研究结果表明:两级螺旋副最佳螺旋升角在50°附近时传动效率最高。搭建了螺旋齿摆动液压缸样机试验台,通过样机试验验证了动力学模型的准确性。
英文摘要:
      A mathematical model of the double screw vice of spiral gear rotary hydraulic cylinder is established, and the dynamic analysis is carried out by ADAMS simulation software. Its maximum angle and output torque under the limit external load were studied. Based on the dynamic model, the key parameters of helical pair were optimized to analyze the influence of different spiral angle on the output performance of the double transmission. The results show that the transmission efficiency is the highest when the spiral angle is about 50 °. The test rig of spiral gear rotary hydraulic cylinder was set up, and the accuracy of the dynamic model is verified through the prototype test.
