Hello, I hope you can help me.  I'm trying to create a device that has a spinning axle and I need to change the rotational force to be perpendicular to the axle. I know there are gears that can fit together have teeth, like the attached picture.  I know there are other types of mechanisms, and some are more creative.  But I also need for the solution to be low friction. What are 2 low friction methods of changing the directional rotation of a power axle 90 degrees? The entire creation is small, probably 12" x 12" Thanks for your help.

Question 4

No you are wrong, time is displament over velocity. Please do number 2 as well
