Abstract

See full text

In an aspect a device for a driven shaft is provided that receives an input torque that varies cyclically between a peak input torque and a low input torque at a peak input torque frequency, which includes a shaft adapter, a rotary drive member, at least one isolation member, a torsional vibration damping structure including an inertia member and a elastomeric damping member, and a supplemental damping structure. The supplemental damping structure applies a supplemental damping torque to resist relative movement between the rotary drive member and the inertia member in addition to damping provided by the elastomeric damping member. A sum of torques including the supplemental damping torque limits a maximum twist between a first end of the driven shaft and a second end of the driven shaft, to below a yield point of the driven shaft.
