I am replacing a friction drive in a device I designed with some proper spur gears, to reduce wear and breakdown of the drive surfaces. Now I am wondering if my new plan is going to work. The problem is that the part I am driving rests fully upon the drive wheel (gear) and a free turning wheel (gear). It is a "drop in" design for convinence.

Imagine a clock - tangent to the outer diameter at 4:30 and 7:30 are the drive and free turning gear. The clock rests soley upon the drive and free turning gear. With gears, is this going to be a problem? Will the pressure of the "clock" resting fully upon the other two cause problems (i.e. the gears "bottoming out" on each other)?

Any help will be greatly appreciated.

Without understanding this completely... my first thought is that your drop in gear will hop out as soon as it sees some torque load...? If you have something that is holding it down where it can't come up... then have a stop so that it also can't go down and put unnecessary load on the gears...?
