摘要
以锯齿螺旋轴为研究对象,建立了锯齿螺纹静力学模型,分析了锯齿螺旋轴传动过程的主要影响因素,揭示了螺旋升角和螺纹头数对螺旋轴传动效率的影响规律,在此基础上,对锯齿螺旋轴结构、螺纹牙侧角进行了优化设计。采用Adams软件对螺旋轴及其连接件进行了三维建模,仿真结果显示:优化后的圆弧形锯齿螺旋轴在运动精度、稳定性、传动效率等方面均得到了明显提升,为锯齿螺旋轴的设计提供了理论依据。
The main factors which influence the spiral shaft transmission process have been summarized by static force analysis of buttress thread. How the helix angle and thread number affect the spiral shaft has been analyzed, according to that the shaft structure and the flank angle have been optimized. In order to verify the optimization, the dynamic simulation has been done with the software ADAMS on basis of the 3D model of spiral shaft transmission system under certain constraints and boundary condition. The simulation results show that the arc buttress tread which is optimized had much better performance than the traditional buttress thread in the movement precision, stability and transmission efficiency.
