Stiff bearing assembly but easily removable axle
Stiff bearing assembly but easily removable axle
(OP)
First of all let me say I'm fairly new to designing bearing assemblies. So sorry for obvious mistakes I might have made. :)
For a testing rig for gears I'm designing a bearing assembly which is really stiff (to get reliable results from the gears the deformation of the frame should be minimal) but at the same time it should be very easy to change the axle. (changing the axle allows for different setups) A first design is attached to this post.
The point that I'm struggling with is that normally you fix the axle with a press fit on one side. How hard is it to remove the axle in such a setup? Could this problem perhaps also be solved by using an adjustable bearing system with a small amount of pre-tension and making both bearing have a sliding fitting on the axle? (does this give a reasonable stiff system?)

As drawn it looks like the pinion gear stays behind as the "axle" is withdrawn. Is that right?
