are "lantern" sprockets necessary
are "lantern" sprockets necessary
(OP)
I was thinking of using a length of 50 roller chain in place of a convex curved rack that is part of a manually adjusted, occasionally adjusted, burner air flow control system.
I understand the standard sprocket tooth form is necessary for the chain to wrap around a sprocket, but I am expecting clearance, not binding, if standard parts are used.
These guys talk about the necessity of a "lantern" sprocket tooth profile when using a roller chain as a rack.

Is that requirement for nice accurate positioning, or to relieve binding ?

If it's just a drop in then the lantern gear teeth look necessary to survive long.
It looks like this system is also referred to as pin-gear drive.
