Drive motor options

Helical gears have an inherent disadvantage , because these load the bearing also longitudal, not only axial. That can be solved by using 2 next to each other in the herringbone setup.

But for our application just straight gears will do nicely.

Hmm, that will defeat the purpose of a light and compact setup if I had to use herringbone gears. I could maybe use helical gears and thrust bearings...but probably its better to keep it simple and do as you said...go with straight gears, any recommendations on who sells loose gears at a reasonable price, preferably within the EU not the States?

I'm confused as to where all the gears are mounted, presumably the first gear is attached to the output shaft of the motor, the second 2 gears are on a separate shaft both attached to te shaft with a grub screw so they rotate at the same speed. Then I don't get where the last gear is connected? Is it on a separate shaft inline with the motor's shaft but only supported on one end?
