Abusing Some 3d Printed Gears

- Testing a 3d printed gear reduction on my bmx test platform , powered by an my6812 motor. As I go I plan on improving things as they break , what a better way to stress some parts other than to ride them . I will be cleaning up the test footage and posting the full drive in another video.
P.S the broken tooth was an issue eventually , this is where the 2 piece gear in the files comes from

Really should use double helical (herringbone) gears if you're going to 3d print them. Stronger, and quieter.
Double helical in fdm style printing leads to excessive friction and premature melting.
Youd think theyd be perfect, but good old straight cuts work best with 3d printing.
Those are 2 different types of gears u noted . The herringbone yes is stronger , helical is not stronger directly but applies force more eventually however helical gears cause side load ( thrust load which the bearings are not setup for and will wear as well as force everything to one side ) . Also straight gears are more efficient . I don't really care about sound level , but losing power to friction I do care about .
@turboprint3d Nice thick grease is about the best you can do besides getting your corners really calibrated on your printer and doing fine touch work with a file for hours.
The 20$ for the gears you need would probably be a better idea long term, but its still fun to play around with the mechanical principals
@turboprint3d no, they are not two different types. A herringbone is a double helical gear. It's clear you're not as aware as you think you are. Maybe you should revisit your theory.
Go carnivore, do some research try it for a week. world of difference.
Don't think the bikes gonna like eating meat ...
