In this paper, a fluctuation of the driving torque and the shaft load in round shape synchronous belt drives and the flat belt drives under no load is studied, From the experimental results, it was confirmed that the configuration in storage of the belt influences the driving torque fluctuation and the shaft load fluctuation at the point where the belt engages or comes off the pulley. Furthermore, the experimental result in flat belt drives are compared with the results of the of the static FE analysis, Almost the same configuration of the belt in storage using in the experiments was used in FE analysis. Although the average shaft load is not equal to that of the experimental results, it was confirmed that the configuration in storage of the belt is the most important factor that influences on the fluctuation of the driving torque.
