Abstract

A noise and vibration attenuating support mounts a rotating member that tends to tilt about and translate along axes transverse to its axis of rotation. The support incorporates a body having mass and a moment of inertia with respect to an axis through the center of gravity of the body. Resilient elements, which are secured to the mass body, mount the rotating member resiliently relative to the mass body and the mass body resiliently relative to a second member. When mounting the rotating member, the support circumscribes and is coupled to the member such that the center of gravity of the rotating member is spaced along the axis of rotation from the center of gravity of the mass body. The support also predominately determines a translational natural mode of vibration with an associated natural frequency at which the mass body translates in resonance along axes transverse to the axis of rotation of the rotating member. Similarly, the support predominately determines a cocking natural mode of vibration with an associated natural frequency at which the mass body cocks or tilts in resonance about axes transverse to the axis of rotation of the rotating member. To reduce the transmission…
