Abstract

The object of this study is to investigate the change of pitch angle of element for metal V-belt Type CVT due to increase of the transmitting torque. 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.
