Description

technical field [0001] The invention relates to a three-dimensional static balance measuring method and device for a spherical rotor of a gyroscope. Background technique [0002] The gyroscope rotor is the core component of the gyroscope, which requires high-speed and stable rotation around the inertial axis during operation. The spatial imbalance of the rotor will cause the rotor to vibrate and cause drift, which directly affects the accuracy and life of the gyroscope, so the balance problem is very important. [0003] Due to the technological structures such as holes and bosses on the spherical rotor of the gyroscope, the traditional orbital balance, swing balance, static balancer method and air flotation balance method are difficult to apply or cannot achieve sufficient balance accuracy. Both the Japanese patent JP11160183 and the Chinese patent CN02145944.4 adopt a three-point support sensor weighing method to measure the static balance of the rotor. [0004] The balan...
