Abstract
The object of this study is to investigate the orbital change of belt with the increase of the transfer torque, during steady-state belt of rotation using a bench-type CVT testing machine. Acceleration sensors were attached to the V-belt to measure accelerations of each element. The pitch angle of each element at the strings also near the entrances and exit was continuously measured by calculating the 3-axis accelerations during the belt travel. Macroscopic change of pitch angle was almost followed by the geometrical change of the angle during the orbital motion of the belt. However, local change of pitch angle at near the entrance and exit of the pulley was not explained by the angle of the geometric posture movement of elements. The pitch angle of each element was locally increased near the entrance and exit of the driven pulley as the load torque increased, while the opposite tendency was observed near those locations of the driving pulley.
