Title: DAMPER ASSEMBLY FOR ROTATABLY COUPLED COMPONENTS
Abstract:
Damper assembly is provided that includes a damper housing and a rotor operably coupled to the damper housing. At least one of the rotor or the damper housing is operable to rotate about a central axis. The damper assembly also includes an elastic shaft extending lengthwise along the central axis. The rotor is attached to the elastic shaft at a distal cross-section along the central axis and attached to the damper housing at a proximal cross-section along the central axis. The elastic shaft has a dampening portion between the proximal and distal cross-sections. The dampening portion is configured to yield to a designated torque applied at the distal cross-section, wherein the dampening portion twists about the central axis. The dampening portion provides an opposing force that resists movement from a first rotational orientation to a second rotational orientation.
