Turnigy 1/16 Spur Gear - Part no. 110BS-30985

thingiverse

Replacement Spur gear for the Turnigy 1/16 buggy and monster beetle. The gear is an odd pitch so took some time to get it right. It ended up with a pitch of 52.493 and an outer diameter of 30mm. The optimal gear angle was 10 degrees. This gear is 1mm thicker than the original and so it is the same width as the pinion at 5mm. It has also been offset by an additional 1mm to compensate for the additional width. UPDATE: I have uploaded an alternative gear that can easily printed in Nylon. The centre of the gear has been beefed up to ensure that the flexibility of the Nylon does not hinder the rigidity of the gear. I have not had a failed Nylon gear as yet. Ensure that you use Cura for the Nylon gear and not sli3er due to the way that it forms the actual teeth on the gear. Anything larger than a 0.3mm nozzle will probably not have the resolution to print the teeth.

At 200% speed I got a few deformities, so slowing the printer down really helped. Tip: When you install the spur gear, remove the spacers between the slipper clutch plates and the gear. This ensure enough space is made for the additional offset and that the clutch screw clear the motor mount. Also do not over tighten your slipper clutch as the give that the clutch provides really increases the longevity of the spur gear as it is not stressed as much. Final point, if you do not know what backlash is, its probably the reason the gear stripped in the first place. Go and watch a couple of YouTube video's how to correctly setup the distance between the spur gear and the pinion gear. I now have 3 1300mah 2s lipo packs on this gear without and signs of odd wearing.
