Helical synchronous belts have been confirmed to reduce transmission error and noise. However, helical synchronous belts under torque incur offset due to the inclination angle of belt at the belt span from the driving pulley to the driven pulley. Side tracking and offset result in damage at the side face of the belt. In addition to damage to the side face of the belt, damage to the belt teeth also occurs due to a non-uniform longitudinal load distribution. Therefore, it is necessary to investigate methods for reducing side tracking and offset. In the present study, side tracking and offset of a helical synchronous belt were analyzed under torque, and the experimental results were compared with calculated values. It was found that side tracking of a belt under torque could be reduced by lowering the installation tension. In addition, the results showed that offset of the belt increases proportionately with torque.
