【摘要】：为分析啮合过程中高速齿轮各相关因素对其本体温度的影响,以标准渐开线高速齿轮为研究对象,基于有限元温度场分析,采用控制变量法,系统量化分析了相关因素对轮齿温度的影响规律及原因。结果表明,轮齿齿面各处本体温度随转速或转矩的增加而升高,且增幅程度逐渐降低;齿宽增加,各点本体升高;轮齿本体温度随模数增加而先减后增;大转矩或高转速下,转速、转矩、齿宽、模数对轮齿温度的影响加剧;轮齿齿面最大本体温度随齿轮箱空气和润滑油温度增减而小幅增减,且不受转速和转矩影响;齿轮端面和啮合面的传热系数对轮齿齿面本体温度影响程度较小,二者增加,齿轮齿面本体温度降低,反之升高。研究为降低齿轮高温失效风险提供参考。
[Abstract]:In order to analyze the influence of relative factors on the body temperature of high speed gear during meshing, the standard involute high speed gear is taken as the research object, based on the finite element analysis of temperature field, the control variable method is adopted. The influence of relative factors on tooth temperature is analyzed quantitatively. The results show that the bulk temperature increases with the increase of rotational speed or torque, and decreases gradually; with the increase of tooth width, the bulk temperature of each point increases; the temperature of gear body decreases first and then increases with the increase of modulus; at high torque or high rotational speed, the temperature of gear body decreases first and then increases with the increase of modulus. The effects of rotation speed, torque, tooth width and modulus on the temperature of gear teeth are aggravated, the maximum bulk temperature of gear tooth surface increases and decreases slightly with the increase and decrease of temperature of gear box air and lubricating oil, and it is not affected by rotation speed and torque. The heat transfer coefficient of gear face and meshing surface has little influence on the temperature of gear tooth surface. The increase of both of them will decrease the temperature of gear tooth surface and increase the temperature of gear tooth surface on the contrary. The research provides a reference for reducing the risk of gear failure at high temperature.
