Description
Technical Field
[0001] The utility model relates to the technical field of gyroscopes, in particular to a lightweight liquid-floating gyroscope structure. Background Art
[0002] Traditional gyroscopes mainly rely on ball bearings to support the rotor. Their structure is relatively simple, and the rotation of the rotor is achieved through the rolling of the balls. However, traditional gyroscope ball bearings rely on direct contact and have a large friction torque.
[0003] Liquid-floated gyros are commonly used in the prior art. Magnesium-lithium alloy is used as the material for lightweight design. Existing liquid-floated gyros suspend the gyro frame assembly with a high-density liquid. Archimedes' principle is used to ensure that the buoyancy of the liquid completely overcomes gravity, achieving neutral suspension and unloading the supporting bearings. The high-speed rotating gyro rotor is sealed in a float filled with an inert gas. The float is suspended in a float such as fluorinated oil. Precise static balance and temperature control ensure that the buoyancy of the float is completely balanced with the weight of the assembly, thereby reducing the friction torque on the jewel bearing used for positioning the float to an extremely small level.
[0004] However, during the use of existing liquid-floating gyroscopes, the equipment on which the liquid-floating gyroscope is installed usually vibrates, which can easily cause the suspension to decompose or volatilize, thereby causing changes in the suspension density and introducing unbalanced torque that affects the measured values of angular velocity and angle.
