Abstract
Four forces act on rings for a metal pushing V-belt. These forces are: two kinds of intercepting forces which prevent blocks from going outside of pulleys ( one caused by pulley thrust, the other caused by centrifugal force ), frictional force acting between the rings and the blocks, and bending force in longitudinal direction.
We successfully measured all four kinds of forces at practical operating conditions for layered rings. In our previous paper [1], the distribution of the ring stress when only innermost rings are set in the metal V-belt was presented. In this paper the argument for the ring stress of layered rings is described.
