Sensor for three-floated gyroscope and stator preparation process thereof

Abstract

The invention relates to a sensor, in particular to a sensor for a three-floated gyroscope and a stator preparation process thereof, and solves the problems of oil leakage of a sensor rotor and asymmetry of a sensor magnetic circuit of an existing moving-coil sensor device. The sensor rotor comprises a rotor bracket, a rotor coil and a rotor pouring sealant layer. The rotor support is an annular support, an annular groove is formed in the circumferential direction of the outer circumferential face of the annular support, and one side wall of the groove is a step face. The rotor coil is wound in the small end of the groove. The pouring sealant is poured in the large end of the groove along the outer peripheral surface of the rotor coil to form a rotor pouring sealant layer. The first end surface of the pouring sealant layer clings to the large end surface of the groove, and the second end surface of the pouring sealant layer is flush with the end surface of the rotor bracket. The sensorstator comprises an inner magnetic conductive ring and a plurality of magnetic poles, and the plurality of magnetic poles and the inner magnetic conductive ring are integrally arranged. By optimizingthe structure of the sensor, the center of mass of the gyroscope does not obliquely float in a certain slope trend any more, and the precision and reliability of the gyroscope are guaranteed.

Description

technical field [0001] The invention relates to a sensor, in particular to a sensor for a three-float gyroscope. Background technique [0002] Due to its small size, high precision, high reliability and other advantages, the three-floating gyro is currently mainly used in the fields of space satellites, open sea positioning and high-precision weapon systems. It is said that the random drift of the three-floating gyro with the highest precision in the world can reach 1.5×10 -7 ° / h, the stable running time of the system can reach 1.0×10 4 h. After decades of development, the domestic three-floating gyroscope has made a series of achievements, and its accuracy is said to have reached 5.0×10 -5 ° / h. Compared with relatively new gyroscopes such as fiber optic gyroscopes, laser gyroscopes, and hemispherical resonant gyroscopes, it still has advantages in terms of market, precision, and engineering practice. However, in recent years, the development of three-float gyroscopes i...
