What Is A Fluid Floated Gyroscope?

May 15, 2020

Suspend the gyro frame assembly with high-density liquid. The Archimedes principle is used to make the buoyancy of the floating liquid completely overcome gravity, and to achieve neutral suspension to unload its supporting bearings. This kind of gyro is called a full liquid floating gyroscope, referred to as fluid floated gyroscope.

Liquid floating gyroscope is a gyro that is widely used in inertial navigation system at present. It belongs to frame type gyroscope. Its high-speed rotating gyro rotor is driven by gyro motor. The main feature of the liquid floating gyroscope is that the rotor is sealed in a floating ball (or float) filled with inert gas, and the floating ball is suspended in fluorine oil. Through precise static balance and temperature control, the buoyancy of the floating ball It is fully balanced with the gravity of this component, so as to ensure that the friction torque on the jewel bearing for positioning the float is reduced to a very small degree.
