摘要

重载齿轮在传动过程中啮合面由于相对摩擦会产生大量的热,导致齿面温度升高、应力增加、可靠性降低,而间接偶合法对热流边界加载区域不能精准确定。采用直接耦合进行齿轮热-结构耦合分析,得到了齿轮啮合动态温度场和应力场分布;并对影响耦合效应的摩擦因数、相对转速、齿轮模数进行了讨论。结果表明,齿轮模数对啮合温升、热应力影响较大,对大模数齿轮设计时需要考虑热-结构的耦合效应。

Abstract

The relative friction surface in the process of the heavy duty gear transmission will generate a lot of heat cause tooth surface temperature rising,increased stress,reduced reliability,but the heat flow boundary load area can’t be precisely determined by using indirect coupling method. By using the direct- coupled method,the gear heat- structure coupling analysis is carried out,the gear dynamic temperature field and stress distribution are got,and the influence of the friction factor,relative speed,gear modulus on coupling effect are discussed. The results show that the influence of gear modulus on engagement temperature,thermal stress is greater,when the large modulus gear design,the heat- structure coupling effect need to be considered.
