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。
In order to analyze the influence of the related factors on the body temperature of high-speed gear in the meshing process,taking the standard involute gear as study object,based on the finite element analysis of temperature field and using the control variable method,the influence law of related factors on gear temperature is analyzed quantificationally. The results show that,the body temperature on tooth surface increase as rotation rate or torque increases,and the temperature increase amplitude decrease as rotation rate or torque increases. The temperature on tooth surface uniformly increase when tooth width increases,the change of modulus cause the changes of multiple factors and temperature on tooth surface decrease and then increase as modulus decreases. When rotation rate or torque is higher,the influence of rotation rate,torque,tooth width,modulus on gear temperature become bigger. The maximal body temperature increases or decreases as air and lube oil temperature,and the change has nothing with rotation rate or torque. The influence of heat transfer coefficients of gear end and meshing surface on gear temperature is relatively small,and temperature decreases as heat transfer coefficients increase. A reference for reducing the risk of gear high-temperature failure is provided.
