Abstract

The relation between axial forces and their distribution on the pulley for a newly–developed block–type CVT V–belt was studied experimentally. The axial force applied to one block is not constant through the arc of contact even when initial tension only without the transmission power is applied. When the belt is in the pulley, according to the contact progress from the entrance toward the exit, the axial force increases rapidly, and finally it records the highest value at the exit point. From the dynamic test, it was confirmed that this belt has high power transmitting ability notwithstanding its compact form. A modified Ogasawara's equation for predicting the relation between two axial forces was also proposed.
