About this model

Video can be found here: STL and Editable Fusion 360 source files can be found here: This servo/gearbox is the new and improved version of my original gearbox design ( The original one had a gear ratio of 30:1 and the speed of the output shaft was about 715 RPM which made it difficult to tune in the right PID parameters. This new version has a gear ratio of about 162:1 which lowers the speed and increases the torque of the output shaft. I choose to go for double helical gears on this one because they produce a lot less noice than regular spur gears and the forces on the teeth are transferred more gradually. The gears rotate around a 6mm stainless steel shaft which is lubricated with bearing grease. Ideally all the gears should have some bearings, this is being considered for the next momen…
