【摘要】 滚锥包络端面啮合蜗杆传动，该传动副的优点为同时啮合的齿对数多和可消除间隙等。根据齿轮啮合原理和微分几何原理建立该传动副的啮合数学模型，从而得到该传动副的啮合函数和蜗杆齿面方程，再推出啮合性能的计算公式，运用Matlab软件分别分析滚锥小端半径、喉径系数及滚锥半锥角对该传动副啮合性能评定参数——诱导法曲率、润滑角、相对卷吸速度和自转角的影响。分析结果表明，该传动副具有较好的啮合性能。更多还原

【Abstract】 The end face meshing worm drive with tapered roller envelope has many simultaneous meshing tooth pairs and can eliminate clearance. According to the gear meshing principle and differential geometry principle, the meshing mathematical model of the transmission pair is established, the worm tooth surface equation and meshing function are deduced, and the meshing performance calculation formula is obtained. Matlab software is used to analyze the effects of small end radius, throat diameter coefficient and half cone angle of cone on the meshing performance evaluation parameters of the transmission pair induced normal curvature, lubrication angle, relative entrainment speed and self rotation angle. The analysis results show that the transmission pair has good meshing performance.更多还原
