Rotary Damping Device

A damping design increases rotational stability for rotary motion mechanical devices which have an oscillating or unstable axis. The device is constructed and works in the following manner.

As seen in the drawing, the device consists of a flexible, circular tube 1 which is filled with oil. The tube 1 terminates on both ends to an adjustable flow control valve 2. The tube 1 is supported by a housing 3.

A rotor 4 has a pair of cylindrically shaped roller bearings 5 which impinge against tube 1. When rotor 4 rotates, the bearings 5 drive the oil in tube 1 in a circular fashion past the flow control valve 2, establishing the damping action.

The rotor 4 is driven by the mechanism to be damped.
