Belt-type continuously variable transmission (CVT) for automobile transmits torque by frictional force, therefore high friction is required in circumferential direction of the pully. However, to reduce friction loss, low friction is required in the radial direction of the pully. Hence, it is important to generate friction anisotropy that satisfies both the frictional characteristics. Surface texturing is one of effective ways to generate friction anisotropy. In this study, 3 types of groove texture were applied to actual CVT pulley by laser processing, and friction tests were performed. As a result, groove texture pattern concentric to the pulley exhibited increase in friction anisotropy. In the presentation, we are going to discuss the detail of the effect of each texture pattern on friction anisotropy.
