Abstract:
1. A system for absorbing vibration in a rotary member having a predetermined rotary speed, the system comprising: a pendulum assembly having a mass and a connecting member, wherein the mass has a predetermined position, the connecting member has a first and a second end, the first end pivotally supports the mass, and the rotary member pivotally supports the second end; a positioning mechanism having a mass and a biasing member, wherein the biasing member has a first and a second end, the first end is fixed to the mass of the positioning mechanism, the second end is fixed to the outer periphery of the rotating member, and the positioning mechanism exerts a force on the mass of the pendulum assembly at least when the rotary member operates below the predetermined rotary speed, and wherein the force exerted by the positioning mechanism orients the mass at the predetermined position when the rotary member operates below the predetermined rotary speed.
