Types 80 & 81 or types
80 & 82 together make up a round belt powered accumulating
roller conveyor for the transportation of lightweight to medium-heavy
products. This works as follows: a drive axle ø 25 or ø
35 mm is installed transversely beneath the rollers.
Polyamide (PA 6) diabolo (deeply grooved) wheels with a sliding
fitting have been threaded onto the axle. A round belt of no more
than ø 6 mm is placed around the diabolo wheel and the groove
in the roller.
The pre-tensioned round belt provides friction between axle and
diabolo wheel. This friction causes the roller to be driven. If
the product on the roller is obstructed, then the diabolo wheel
can slip on the axle. The advantage of this method of delivering
power to the rollers is that it operates near enough silently, even
at high speeds.
You should take into account that the roller can acquire a static
electric charge if non-conducting bearing cartridges are used, which
can cause sparks to jump between the roller and the frame.
