| 摘 要： | 通过对双级正弦活齿传动活齿啮合副进行受力分析，推导出了活齿传动系统输出力矩表达式，进而建立了系统传动效率计算公式。运用效率公式对系统传动效率进行分析，得到了参数变化时系统传动效率的变化规律。结果表明：为了提高传动效率，应增大正弦滚道幅值、活齿中心圆周方向旋转半径以及合理分配传动比。研制出了双级正弦活齿传动样机，并进行了传动效率实验，测得实验效率与计算效率接近，验证了理论分析的正确性。

| Abstract: | According to force analysis of the movable tooth meshing pair of a two-step sine movable tooth transmission, the expressions of the output torque of the movable tooth transmission system were deduced, and then the formulas for calculating the transmission efficiency of the system were given. The transmission efficiency of the system was analyzed by using the efficiency formula, and the variation laws of the transmission efficiency of the system were established. The results show that in order to improve the transmission efficiency, the amplitude of sine tracks and the circumferential radius of the center of the movable tooth should be increased, and the transmission ratio should be allocated reasonably. In addition, a two-stage sinusoidal movable tooth transmission prototype was developed, and the transmission efficiency experiments were carried out. The experimental efficiency is close to the calculation efficiency, which verifies the correctness of the theoretical analysis. |
