IMPROVED GYRO-STABILIZED APPARATUS

摘要

A gyro-stabilized apparatus for a ship-board antenna (22) or the like includes an azimuth platform (18) stabilized by gyro assemblies (32, 34, 36 and 38) each gyro assembly having a housing (84) which serves as an end bell for a gyro motor (82) and which is pivotally supported on the platform by trunnions (106, 108) having bearings (118) thereon resiliently supported in a bearing housing (110). A coaxial bore through one trunnion passes electrical conductors (128) to the gyro motor from the platform without exerting extraneous torques on the gyro assembly during precession. The platform is supported on a support structure (14) by a gimbal assembly (150) which enables precise alignment of the gimbal axes intersection with the rotational axis of the platform, and enables precise alignment of the gimbal axes with respect to the pitch and roll axes of the ship. The gimbal assembly affords an unobstructed passage through the center thereof for cables. An elevation assembly (20), pivotally mounted on the azimuth platform (18) for supporting an antenna, is formed so that it can be rotated from horizon-to-horizon over zenith.
