Abstract
An internal viscous rotational damping (VRD) assembly for transmitting torque from a drive member connector to a load member connector is provided. The VRD assembly comprises a spacer tube connected between the drive member connector and the load member connector, wherein the spacer tube includes a longitudinal axis and an inner surface that extends along the longitudinal axis. The VRD assembly further includes a damper bar disposed within the spacer tube. The damper bar includes an outer surface, wherein a cavity is defined between the outer surface of the damper bar and the inner surface of the spacer tube, and wherein the cavity is configured for receiving a viscous fluid.

An internal viscous rotational damping (VRD) assembly for transmitting torque from a drive member connector to a load member connector, wherein the drive member connector is coupled to a driving input shaft, and wherein the load member connector is coupled to a driven output shaft, the internal VRD assembly comprising:
- a spacer tube connected between the drive member connector and the load member connector, wherein the spacer tube includes a longitudinal axis and an inner surface that extends along the longitudinal axis;
- and
- a damper bar disposed within the spacer tube, wherein the damper bar includes an outer surface, wherein a cavity is defined between the outer surface of the damper bar and the inner surface of the spacer tube, and wherein the cavity is configured for receiving a viscous fluid.
A damper bar for use with an internal viscous rotational damping (VRD) assembly, wherein the VRD assembly includes a spacer tube connected between a drive member connector and a load member connector, wherein the spacer tube includes a longitudinal axis and an inner surface that extends along the longitudinal axis, the damper bar disposed within the spacer tube and comprising:
- a first end fixedly connected with the spacer tube;
- a second end that is not fixedly connected with the spacer tube;
- and
- an outer surface spaced apart from the inner surface of the spacer tube to define a cavity therebetween configured for receiving a viscous fluid in the cavity.
A flexure spacer coupling comprising:
- a drive member connector coupled to a driving shaft;
- a load member connector coupled to a driven shaft;
- an internal viscous rotational damping assembly configured for transmitting torque between the drive member connector and the load member connector;
- a spacer tube connected between the drive member connector and the load member connector, wherein the spacer tube includes a longitudinal axis and an inner surface that extends along the longitudinal axis;
- a damper bar disposed within the spacer tube, wherein the damper bar includes an outer surface, wherein a cavity is defined between the outer surface of the damper bar and the inner surface of the spacer tube;
- and
- a viscous fluid disposed within the cavity.
