发明名称 TENSIONER FOR REDUCING VIBRATION
摘要 PURPOSE: A tensioner for damping vibration is provided to improve the durability of the system, and to extend the life span of the blade-type chain tensioner by decreasing internal vibration of the blade-type chain tensioner efficiently. CONSTITUTION: A blade-type chain tensioner(10) includes a shoe(30) adapted to impart tension to a chain(16), a blade spring(28) engaging the shoe, a piezoelectric strain element(35) coupled to the blade spring or the shoe, and a circuit(34) adapted to receive a voltage or voltage data signal generated by a sensor(33) coupled to the blade spring and shoe assembly in response to the vibration having a predetermined frequency or frequency band occurring in the blade spring and shoe assembly. The circuit is adapted to operably interact with the piezoelectric strain actuator element to induce the vibratory moment therein effective to reduce the vibration of the chain tensioner.
