Study on the calculat i on methods of meshing interval and number of meshing teeth in cycloidal pinwheel mechanisms

The meshing interval and count between the cycloidal and pinwheel teeth in cycloidal pinwheel mechanisms are essential for modifying the tooth profile. To determine these parameters effectively, the engagement initiation point between the cycloidal and pinwheel teeth was defined using the mechanism’s kinematic characteristics. Using Hertzian contact theory, the contact deformation of each component was calculated to identify the meshing tail point. An analysis model was created to determine the number of meshing teeth based on the meshing interval, allowing for accurate calculation of the teeth count. The minimum number of meshing teeth required for contour modification was explored using kinematic theory. The importance of the cycloidal pinwheel mechanism design parameters in improving transmission accuracy was validated through example analysis, providing a theoretical basis for the design and profile modification of cycloidal pinwheel mechanisms.
