Study on a metal pushing V-belt type CVT: band tension and load distribution in steel rings

Abstract The power transmitting mechanisms for laminated belts were numerically investigated to analyze belt tension in each band of the ring of metal V-belts. The numerical model consists of linear springs and frictional elements. It was shown that the innermost band must support significantly greater load than any other bands when the frictional coefficients between two bands are lower than that between the innermost band and the blocks. The frictional coefficients between bands should be slightly larger than that between the innermost band and the blocks in order to reduce the load distribution to the innermost band.
