Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0031] As shown in Figure 2, the support of the present invention is made up of support ring 3.1, support bar 3.2, support base 3.3, front leg 3.5 and two rear legs 3.4, and the connection between each part is connected with pin 3.6. The support rod 3.2 is a rod with a round or square cross section. The support ring 3.1 installed at one end of the support rod 3.2 is a circular ring with a tapered hole. The inner diameter of the support ring 3.1 is smaller than the diameter of the measured spherical rotor. In order to ensure the stability of the rotor on the support ring 3.1, the inner diameter of the support ring 3.1 takes a value between 1 / 3 and 1 / 2 of the rotor diameter; The two ends of the support rod 3.2 are vertically connected with the support ring 3.1 and the support base 3.3 on a plane along the central axis of the support rod 3.2, and...

Abstract

A 3D static balance measuring method utilizing ball form rotator of gyroscope includes using only one electronic analysis balance in high accuracy to carry out multitime of space multiangle weighing then utilizing mathematical statistic method to eliminate off random error of measurement for deriving out 3D space eccentric position of ball form rotator. The measuring device used for realizing said method is also disclosed.

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...
