以大型养路机械的十字轴式万向联轴器为研究对象,应用运动学理论分析了当十字轴式万向联轴器的输入轴做匀速转动时,其输出轴做圆周性不均匀转动的性能。分别从角速比、不均匀系数和角加速度等方面对十字轴式万向联轴器定量表达了其不均匀性。结果表明,随着十字轴式万向联轴器输入、输出轴夹角、转速的增大,其输出轴最大角加速度增大,使其最大惯性力矩增大。十字轴式万向联轴器的输入、输出轴夹角是影响其不均匀性的关键参数,当十字轴式万向联轴器输入、输出轴夹角增大时,其输出轴转角波动性增大。减小输入、输出轴夹角是提高十字轴式万向联轴器传动效率的唯一途径。
Taking the universal coupling with spider of heavy-duty maintenance machinery as study object, the kinematics theory is used to analyze the performance of the universal coupling with spider when the input shaft rotates at a uniform speed, and the output shaft rotates periodically unevenly around the circumference. It quantitatively expressed the unevenness of the universal coupling with spider from the aspects of angular speed ratio, coefficient of unevenness and angular acceleration. The results indicate that, with the increase of the angle and rotational speed of the input / output shaft of universal coupling with spider, the maximum angular acceleration of the output shaft increases, so its maximum inertia moment increases. The angle between the input / output shaft of the universal coupling with spider is a key parameter that affects its unevenness. When the angle between the input / output shaft of the universal coupling with spider increases, the fluctuation of the output shaft rotation angle increases, so reducing the input / output shaft angle is the only way to improve the transmission efficiency of the universal coupling with spider.
