Abstract

The invention relates to a magnetically suspended gyroscope, which solves the technical problem that the existing gyroscope has bad precision and high hazard rate. The invention includes a shell, a gyro machine which is equipped in the shell, a sensor, a torquer, a floating ball and a magnetic suspension device, the magnetic suspension device includes a magnetic suspension magnetic valve, a press ring magnetic valve, a pressure spring, a press ring, a contact terminal, a platen and a limit ring; the magnetic suspension magnetic valve is equipped over the floating ball and fixed on the shell, the press ring magnetic valve is equipped around the magnetic suspension magnetic valve in a circle and fixed on the shell, many pressure springs are uniformly between the press ring and the press ring magnetic valve in circumference, the platen is fixed on the extension axis and is perpendicular to the axis, three equally spaced contact terminals are equipped on the outer circumference of the upper surface of the platen, the limit ring is equipped on the inner side of the shell to support the platen. The invention has the merits of high floating precision, low perturbed moment, good adaptive capacity to environment and high gyroscope precision.

Description

technical field [0001] The invention relates to a magnetic levitation gyroscope which uses a magnetic field to float a gyro float. Background technique [0002] Gyroscopes are widely used in the control systems of launch vehicles, strategic and tactical missile weapons, telemetry systems, and high-precision gyro north finders. It is an important stand-alone control system. The floating system is a key part of the gyroscope. At present, gyroscopes generally use methods such as liquid flotation, air flotation, bearings, and slings. However, the structure of the above floating method is complicated, resulting in poor precision of the gyroscope and high failure rate. Contents of the invention [0003] The invention provides a magnetic levitation gyroscope, which solves the technical problems of poor accuracy and high failure rate caused by the existing gyroscopes using floating methods such as liquid flotation, air flotation, bearings, and suspenders. [0004] Technical solu...
