摘要
以渐开线直齿圆柱齿轮为研究对象,利用前期研究所得到的摩擦因数公式及多体动力学软件ADAMS,可以求得主、从动齿轮在不同啮合位置的摩擦热流量。应用ANSYS软件对齿轮进行稳态温度场分析,研究转速对齿轮温度场的影响。结果表明,考虑到齿轮在不同啮合位置的摩擦因数不同,可以更加准确地分析齿轮的本体温度场;齿轮表面温度场的分布主要与传输到齿面的摩擦热流量和齿面散热有关;齿轮转速是影响齿轮本体温度的重要因素,主、从动齿轮的齿面最高温度均随着转速的增加而升高。
Taking apair of involute spur gear as the object of study,by using the formula of the friction coefficient obtained from the prophase study and the multi-bodied dynamics software ADAMS,it is possible to calculate the heat flow of friction at any point on the line of contact of driving gear and follower gear.The influence of rotate speed on gear temperature field is studied,by applying the ANSYS,the analysis of the steady temperature field of gear is carried out.The result shows that,in considering the friction coefficient of gears is changeable in different position of meshing,the analysis of gear temperature field distribution can be more accurate.The temperature field distribution on gear surface is related to the heat flow transmitted to gear surface and heat loss.The gear rotate speed is an important factor to influence gear temperature,the maximum temperature of the driving gear and the follower gear are directly proportional to the rotate speed.
