I would like to know what mechanical parts can be used to convert a rotation movement from an axis to another.

For example: You have the shaft of a motor rotating vertically, but you need to rotate a part horizontally.

I already found the worm drive assembly but I would like to know if an "exhaustive" list exists somewhere with pro/con for each.

The go-to solution is bevel gears. They are used when the shafts would intersect and allow the same ratios as normal gears.

You can also make one of the gears a crown gear so the other gear can be a normal spur gear.

A universal joint is also an option if the angle isn't too big.

  • $\begingroup$ Are there existing belt based solutions ? I'm a little bit worried by backlash that could be added by bevel gears. $\endgroup$ – LiohAu Nov 7 '15 at 21:47
  • $\begingroup$ There is backlash in belts too as the tension is transfered to the other side of the belt. But you can use cones as friction gears. $\endgroup$ – ratchet freak Nov 7 '15 at 22:14
