摘要

摘要: 重合度是影响齿轮传动啮合性能的主要因素，是判断齿轮传动连续性及传递载荷均匀性的关键指标。S型齿廓曲线齿轮是基于提高齿轮接触强度而提出的一种新型齿廓曲线齿轮，为进一步探究其啮合性能，推导了S型齿廓曲线齿轮传动的重合度计算公式，讨论了S型齿廓曲线齿轮的重合度随齿数、模数、分度圆压力角及衍生系数之间的变化规律，并与相同基本设计参数下的渐开线少齿数齿轮作了对比分析。结果表明，S型齿廓曲线齿轮的重合度较同参数的渐开线齿轮有较大优势。

Abstract: Contact ratio is a main factor to influence meshing performance of gear transmission, and it is also a key index to judge continuity and load distribution of gear transmission. Gear with S-shaped tooth profile is developed as a new tooth profile of gear so as to enhance contact strength of gear. In order to further study on it, the formula is deduced to calculate the contact ratio of gear transmission with S-shaped tooth profile, and the change law in contact ratio is discussed varying with the number of teeth, modulus, pressure angle, and derivative coefficient, which is comparing with the involute gear with small number of teeth under the same design parameters. And the results show that the gear with S-shaped tooth profile has a large advantage in contact ratio comparing with the involute gear under the same parameters.
