Abstract

In the context of high-precision manufacturing, filling the gap in the study of the correlation between helical gear dynamics and thermo-cavitation has a significant impact on the optimal design of transmission systems. For this purpose, a cavitation two-phase flow research system containing fluid energy, temperature and dynamic model is constructed, aiming at studying the phenomenon of vibration-cavitation under the non-constant flow and variable temperature of oil in helical gear system, analyzing the evolution law of cavitation in the meshing region and revealing the thermo-cavitation generation mechanism under the influence of vibration. Besides, the reliability of the numerical method is assessed by the relative error between the experimental and simulation results. The results show that fluid thermal effect has a significant impact on cavitation at extreme operating conditions, with high speeds being the main factor in the dramatic increase in cavitation. The load profoundly affects the fluctuation of cavitation and the contact surface temperature, but there exists an optimal value to achieve a balance between the two, the value of helix angle between 15° and 20° is a well choice.

螺旋齿轮振动引起的热空化研究

在高精度制造的背景下，填补斜齿轮动力学与热空化关系研究的空白对传动系统的优化设计具有重要意义。为此，构建了一个包含流体能量、温度和动力学模型的空化两相流研究系统，旨在研究斜齿轮系统中油液非定流变温条件下的振动空化现象，分析啮合区域空化的演化规律，揭示振动影响下的热空化产生机理。并通过实验结果与仿真结果的相对误差来评价数值方法的可靠性。结果表明，在极端工况下，流体热效应对空化有显著影响，高速是导致空化急剧增加的主要因素。载荷对空化和接触面温度的波动影响较大，但两者之间存在一个最优值，螺旋角在15°和20°之间是一个较好的选择。
