Abstract
Performance for a frictional power transmission belt such as flat or V-ribbed belts is usually obtained by experiments using two pulleys system for instance and expressed as torque or horsepower of driven axis at the 2% ship ratio. On the other hand few theoretical studies on the performance have benn reported. We have already reported theoretical prediction method of the performance in which tension is set up by fixed pulley. In this paper, a formula to predict the performance in case of tension set up by dead weight (DW) is introduced. Then, validities of the formula are verified by experiments and finally comparison of the performance between fixed pulley system and DW system is described.
