Abstract

Vibration characteristics of a CVT metal belt were evaluated in terms of vibration transmission characteristics of two bearing sections for the DR and DN pulleys. While the resonance phenomena occured in the inter-axial vibration on conventional belts at 800-840 Hz, they did not occure on the evolutionary type. It was clarified that this resonance phenomena is caused by the additioal spin by the spinning motion of the element in the string section.
