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 lbs in2 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 40,000 lbs in2 to be accelerated at a rate of 2.5 rpm/s or greater.

    一种陀螺横摇稳定器包括具有支撑框架的常平架和构造成维持低于环境压力的封壳、包括飞轮和飞轮轴的飞轮组件、用于将飞轮可旋转地安装在封壳内的一个或多个轴承、用于使飞轮旋转的马达以及用于冷却支撑飞轮的轴承的轴承冷却系统。对于较小的单元,该轴承冷却系统有效地使得具有小于40,000 lb in2的转动惯量的飞轮能够以5 rpm/s或更高的速率加速。对于较大的单元,该轴承冷却系统有效地使得具有大于40,000 lb in2的转动惯量的飞轮能够以2.5 rpm/s或更高的速率加速。
