基于Romax的潜水螺旋泵减速箱传动系统动力学分析

Dynamic Analysis of Transmission System of Submarine Gearbox Based on Romax

以某螺旋泵配套设计的减速箱传动系统为研究对象,建立起考虑轴系变形、齿轮受力、传动效率等影响因素的传动系统模型,进行静动态分析、动力学仿真及模态分析。针对水下实际工况,对传动误差偏大及啸叫进行仿真分析,得出具体的原因为振动与噪声及齿轮偏载造成的齿轮啮合冲击。通过齿面修形和优化齿形,可有效降低齿轮啮合冲击及啸叫,降低传动误差。

This paper takes the gearbox transmission system of a screw pump as research object,establishes the transmission system model in consideration of the influence factors of shafting deformation,gear force and transmission efficiency,and makes the static,dynamic and modal analysis and the dynamic simulation.According to the actual working condition under water,it also does the simulation analysis of the large transmission error and the noise.The specific reason is the meshing impact caused by the vibration and noise and the gear partial load.By modifying the tooth surface and optimizing the tooth shape,the meshing impact,noise of the gear,and transmission error can be reduced greatly.
