- TL;DR Summary
- I'm building a pan/tilt mechanism with a small stepper motor, and I need to design a simple 3d printable gearbox with a 20:1 ratio (aprox)
Hi,
As the summary says, I'm trying to design a simple gearbox with an approximate ratio of 20:1. I have two preliminary designs, one using a worm gear and another using a train of 5 spur gears. Both designs give me the desired ratio, but I really don't know which one I should choose.
The application requires an output torque of around 5kg/cm, and a maximum speed of 0.5RPM.
Both designs are pretty much the same in terms of manufacturing cost.
Coud you please suggest which option is better and explain why?
Thanks
