Abstract
A damping mechanism may comprise a housing, a shaft, a spring arm assembly including a first spring arm, wherein the spring arm assembly is coupled to the shaft and configured to rotate in response to a rotation of the shaft, wherein the first spring arm extends relatively radially outward of the spring arm assembly toward the housing in response to the rotation of the shaft, and wherein the rotation of the shaft is damped in response to extending the first spring arm.
Claims20
A rotational damping mechanism, comprising:
- a housing;
- a rotating member;
- a spring arm assembly including a first spring arm,
- wherein the spring arm assembly is coupled to the rotating member and configured to rotate in response to a rotation of the rotating member,
- wherein the first spring arm extends radially outward of the spring arm assembly toward the housing in response to the rotation of the rotating member, and
- wherein the rotation of the rotating member is damped in response to extending the first spring arm due to a friction brake force caused by extending the first spring arm and an eddy current brake force caused by extending the first spring arm.
A hook assembly for a hoist system, comprising:
- a housing;
- a bearing disposed within the housing;
- a hook coupled to the bearing and configured to rotate axially about the bearing;
- a spring arm assembly including a first spring arm,
- wherein the spring arm assembly is coupled to the hook and configured to rotate in response to a rotation of the hook,
- wherein the first spring arm extends radially outward of the spring arm assembly toward the housing in response to the rotation of the hook, and
- wherein the rotation of the hook is damped in response to extending the first spring arm.
A aircraft comprising:
- an airframe;
- a hoist system coupled to the airframe;
- and
- a hook assembly coupled to the hoist system comprising:
- a housing;
- a bearing disposed within the housing;
- a hook coupled to the bearing and configured to rotate axially about the bearing;
- a spring arm assembly including a first spring arm,
- wherein the spring arm assembly is coupled to the hook and configured to rotate in response to a rotation of the hook,
- wherein the first spring arm extends radially outward of the spring arm assembly toward the housing in response to the rotation of the hook, and
- wherein the rotation of the hook is damped in response to extending the first spring arm.
