I need to design a joint that slides while it is pivoting. I can provide more details if needed, but here are the basics:
-This is part of a precision motion imaging system, so eliminating slop or play in the joint is highly desirable.
-The system will be driven by a reciprocating motor, so, back-and-forth motion is what would produce the slop.
-I need the joint to be relatively small: the initial concept is a .5" cam follower in a slot that is just slightly wider.
The main problem I see with the initial concept is making the slot sized perfectly, so that there would be minimal to no play of the follower in the slot. I considered mounting some sort of bushing in the body of a small linear guide/track system (i.e. Igus Drylin T miniature), this seems a bit too cumbersome and may be too big still. Maybe it could be as simple as a precision ground aluminum pin in a precision machined aluminum slot.
I'm not necessarily looking for a solution, but if anybody could point my in a general direction or show me existing examples of this type of joint, that would be great!
Many thanks!
