small gear box worm extreamly high torque

thingiverse

I'm working on building a small gearbox with an extremely high torque output, which is going to be my last motor project. This motor has more torque than 15 gearboxes with only three gears, and that's pretty darn impressive if I do say so myself. I'm extremely proud of what I've accomplished, even if nobody else shares my enthusiasm. This gearbox has the beefiest gears I've ever seen, making it highly unlikely to strip them. If any gear were to strip, it would be the worm, which is easily replaceable. I'm considering adding a safety gear to protect against over-torque, but the safety gears in the boxes I purchase tend to cancel out the torque capacity of the gearbox, rendering it useless. As a result, I've had to bypass these devices every time. To print the worm flat at maximum resolution on a raft, I recommend using my pen printer at 0.2 layer height, which has yielded good results so far. My printer can go down to 0.1 layer height for even better quality, but some post-filling may be required. The easiest way to do this is by attaching the worm to the motor and lightly smoothing it out with sandpaper, then cleaning between the worm with a triangle file. When assembling the gears and box, I recommend working on them one at a time, starting with second gear and the worm before inserting the other gears. For cutting the pens, use 22mm for second and third gear, and 16mm for the output gear.
