Pload support and idler spacing

Conveyor Overview SAIMH

On the carryingside, the mass of the belt plus the load conveyed is greater than the mass to be supported on the returnside and thus, for the tension in the conveyor belt (by the takeup and induced by the drive unit), the idler spacing is selected accordingly.

An idlerwheel may be used as part of a friction drive mechanism. For example, to connect a metal motor shaft to a metal platter without gear noise, early phonographs used a rubber idler wheel. Likewise, the pinch roller in a magnetic tape transport is a type of idler wheel, which presses against the driven capstan to increase friction.
