Reversing gear set

thingiverse

This clever device showcases an ongoing movement of input (orange gears) driving an output gear (small white gear), rotating first in one direction and then reversing its rotation. This process is illustrated vividly in this video: https://youtu.be/_0XB8Rn9RqA. For a more detailed visual representation, check out this animation: https://youtu.be/jA5n5GlCb5U, created using Blender 2.76 with the Physics engine. A close examination of the animation reveals that the trailing tooth of the central gear and the ring gear have been slightly reduced in height. The physics engine will only function if this is taken into account; however, it is essential to note that an even more minor diameter for a planet gear could potentially achieve better engagement with other gears without necessitating adjustments to the trailing teeth. To alleviate any sloppiness, consider using a planet with a 29mm outer diameter. As an alternative solution, I've uploaded a separate planet model measuring 31mm in diameter which likely won't require modifications of the trailing teeth. The idea for this design was born from inspiration garnered from another video: https://www.youtube.com/watch?v=3aobPgGzB-U&list=PLB0IDKx1j2rxVpbfnvui1v5lDLPlaB2gx&spfreload=1. It was brought to life with the help of MOI's design capabilities, subsequently printed on an Ultimaker 1 using Diamond Age PLA. Instructions for Assembly The STL files included are appropriately oriented for printing, so it is imperative to double-check the settings prior to printing. I opted to use Brim support for the tall vertical components to prevent warping during the build process. Although not entirely necessary, I utilized Support material for the counterbores in the base plate. Upon completion of the print job, carefully clean all gear teeth where they have come into contact with the build plate, as debris may interfere with their operation. Subsequently, assemble the handle using a soft hammer, and note that you will need 11 three-millimeter Button Head Cap Screws measuring twelve millimeters in length to secure the parts together effectively; ten-millimeter long screws may suffice but ensure they are securely fastened nonetheless.
