spherical symmetric top

Abstract

A spherical symmetrical gyroscope is provided, which has a gyroscope motor, a gyroscope inner ring assembly and a gyroscope outer ring assembly associated with the gyroscope motor, a spherical torque device and a spherical angle sensor installed symmetrically around the gyroscope motor, and the gyroscope motor, the gyroscope inner ring assembly , the gyro outer ring assembly, the torque device and the angle sensor are all assembled in a closed casing, and the gyro motor is spherically symmetrical, and is assembled in a gyro room that is spherically symmetrical with the same center and different diameters; The motor is concentric with the center of the sphere, and the gyro room and the gyro motor are provided with a biaxial torque device, a differential angle sensor and a shell with the same spherical center and different diameters and a spherical symmetrical structure from the inside to the outside. The present invention adopts a more compact spherical symmetrical structure design for the overall structure of the gyroscope to minimize the installation gap of the rotor gyroscope as a whole and the components along the axial direction of the gyroscope motor to meet the needs of miniaturization, light weight, high precision and high precision of the rotor gyroscope. The cost-effective market demand fills the technical gap in the domestic market.

Description

technical field [0001] The invention belongs to the technical field of rotor gyroscopes using inertial navigation and control technology, and specifically relates to a spherical symmetrical gyroscope. Background technique [0002] The small rotor gyro is a supporting product of a certain type of missile. It is installed on the dual-axis stable platform of the missile seeker, and uses the fixed axis and precession of the gyro to stabilize and control the dual-axis stable platform. The angle measurement system provides a precise inertial reference, so that the missile can accurately capture and track dynamic targets in the air. Under the existing technology, the three-degree-of-freedom small rotor gyroscope consists of such as figure 1 The shown gyro motor (a), gyro inner ring assembly (b), gyro outer ring assembly (c), permanent magnet torque generator (d), angle sensor (e) and housing (f). Among them, with the traditional cylindrical miniature gyro motor as the center, the...

Problems solved by technology

Among them, with the traditional cylindrical miniature gyro motor as the center, the torque generator and angle sensor of the same traditional configuration are arranged symmetrically along the axial direction of the gyro motor shaft in a spatial cylindrical distribution, and are installed on the shaft extending along the axial direction of the gyro motor shaft. In the cylindrical shell of this type of rotor gyroscope, there is too much space margin along the axial direction of the gyroscope motor shaft
