【 摘 要 】

The general conclusion from the literature on centrifugal effect on chain transmissions is that, a component Fc, equilibrating the centrifugal force Fcf, is loading the chain on all its length. The component Fc is creating a supplementary traction force in the chain and in the same time, it creates a release of the initial tensioning of the transmission. This research on centrifugal effect on the load of chain and belt transmissions has its base on the results that we obtained on measuring the tensioning of a chain drive. The results showed a difference to the theory previously presented. The stiffness of chain, supports and tensioning devices must be considered. The release of the shafts is measured and calculated for several chain transmissions and for different initial tensioning, using the same supports.
