Nema 17 16:1 Gearbox
by Thingiverse
Last crawled date: 4 years, 3 months ago
I designed this gearbox to fit onto a nema 17 stepper motor, whilst also being able to be mounted where a regular nema 17 can be mounted.
The above video shows it running as well as assembly instructions! (Click on the image)
Alternatively, written instructions are available here: https://www.instructables.com/id/3D-Printed-161-Nema-17-Gearbox/
This allows you to increase the torque in many applications without redesigning the machine you will be using this on.
It has 3 pairs of 12 tooth gears turning 30 tooth gears, so that gives 3 reductions of 0.4. This results in the gearbox having a ratio of 15.625:1. Meaning that every 15.625 revolutions of the motor, the gearbox shaft will rotate once.
Supplies needed:
You will need:
3D printed parts
Nema 17 Stepper Motor
2x MR105-ZZ bearings (5x10x4mm)
7x M3 Nut
2x 6mm M3 Screw
2x 10mm M3 Screw
2x 25mm M3 Screw
M3 Grub Screw
50mm or longer M5 Bolt with Hex Head
2x M5 Hex Nut
CA/Super Glue
