Small side project: 16:1 worm gear reducer for NEMA-23 motor

Small side project: 16:1 worm gear reducer for NEMA-23 motor
January 25, 2017 09:21PM
While researching worm gear drives for my CoreXY printer with belt lifted Z axis, I ran into plastic worm and disc gear sets on ebay for $8. They are made for garage door openers. I ordered a set and designed a housing for them. One side of the shell is printed and the bearings and gears fit perfectly. The motor attaches on the right side. The other half of the shell is printing now. I'll still have to make the shafts for the gears- planning on turning them on a lathe.





If it works OK, I'll put the design on my web site, and I'll probably design another version for NEMA-17 size motors.

Lots of gear sets out there.
I wonder if they are all the same ---- made in Guanchou, China --- for all the garage door openers?

You may want to design in space for spring or Belleville washer to load worm --- to minimize backlash?
