A gyroscopic boat roll stabilizer for a boat comprises a gimbal, having a gimbal axis, an enclosure mounted to the gimbal and configured to precess about a gimbal axis, a flywheel assembly rotatably mounted inside the enclosure for generating a torque that is applied to counter a rolling motion of the boat, and a braking system for controlling precession of the enclosure.

Braking system for gyroscopic boat roll stabilizer

A gyroscopic roll stabilizer comprises a gimbal having a support frame and enclosure configured to maintain a below-ambient pressure, a flywheel assembly including a flywheel and flywheel shaft, one or more bearings for rotatably mounting the flywheel inside the enclosure, a motor for rotating the flywheel, and bearing cooling system for cooling the bearings supporting the flywheel. For smaller units, the bearing cooling system is effective to enable a flywheel with a moment of inertia less than 40,000 lb into be accelerated at a rate of 5 rpm/s or greater. For larger units, the bearing cooling system is effective to enable a flywheel with a moment of inertia greater than 40,000 lb into be accelerated at a rate of 2.5 rpm/s or greater.

The bearing cooling system enables heat generated by the bearings to be transferred through the flywheel shaft to a heat sink disposed within a cavity in the end of the flywheel shaft, or to a liquid coolant circulating within the cavity.

For smaller units, the bearing cooling system is effective to enable a flywheel with a moment of inertia less than 11.7 kg.m(40000 lbm in) to be accelerated at a rate of 5 rpm/s or greater. For larger units, the bearing cooling system is effective to enable a flywheel with a moment of inertia greater than 11.7 kg.m(40000 lbm in) to be accelerated at a rate of 2.5 rpm/s or greater.

The braking system is configured to enable precession in the first and second directions of up to at least 45 degrees.

An electronically adjustable damper system includes at least one electronically adjustable damper. The electronically adjustable damper includes at least one electronically controlled valve, whereby, the damper is electronically adjustable. The electronically adjustable damper system also includes a controller for adjusting each of the electronically adjustable dampers independently via the electronically controlled valves, and a remote electronic device. The electronically adjustable damper system allows a user to tune the dampers by allowing a user to adjust the electronically adjustable damper system to different applications and functions for various users, conditions, or both.

Electronically adjustable damper and system

An adjustable rebound buffer includes: an outer perimeter, a central shaft hole and at least one adjustable hole. The outer perimeter is sized to fit inside a buffer cavity of the hydraulic damper. The central shaft hole is sized to fit around a damper shaft and position the adjustable rebound buffer on the damper shaft. The at least one adjustable hole provides an adjustable bleed path through the adjustable rebound buffer. A hydraulic damper with the adjustable rebound buffer includes the buffer cavity, wherein, the outer perimeter of the adjustable rebound buffer is adapted to fit inside the buffer cavity as the hydraulic damper approaches full extension.
