Normal gears with teeth are quite easy to understand intuitively, but the first time you look at a cycloidal gear it might be hard to see how it achieves the reduction it does. Below is an image of the resulting 3D print, as well as the workspace in Fusion that is generated: Separate PartsĬycloidal gears are neat in my book not only because of their looks, but also because of the way they work. The tolerances are set to 0.5 mm, which is optimal for when I printed it on my CR-10. In addition to this, are also the 3 STL files the script generates, so you can use them as test prints. Within the Example folder above, you can find a Fusion 360 file that contains a cycloidal gear setup that was generated by the script. It accepts a double and is parsed in units of centimenters.īelow are images of the 3 distinct bodies that are generated by the script:īelow are the 3 sketches generated by the script: Disk Height: Specifies the height of the cycloidal disk.It accepts a double and is parsed in units of centimenters. Cam Height: Specifies the height of the cam or eccentric bearing.Pin Height: Specifies the height of the pins and center pin that are attached to the base plate.Base Height: Specifies the height of the base plate.As a result, the outer diameter of the cam is offset by this value, and the eccentric inner hole for the central pin is also offset by this value. Cam Tolerance: This is the tolerance specified for the cam.It accepts a double that is considered to be in units of centimeters. ![]()
