Embodiment Construction

[0016] An example of a gyroscope figure 1 Shown: including the balance ring 2 and the counterweight 7, the balance ring is provided with a mounting hole 1 whose axis extends in the up and down direction, the wall of the mounting hole is provided with an internal thread, and the wall of the mounting hole is provided at the lower end of the internal thread There is an inversion edge 3. The counterweight is a sleeve-like structure, and the counterweight has an inner hole 6 coaxial with the installation hole (that is, a central hole). The outer peripheral surface of the counterweight is provided with an external thread 5 that cooperates with the inner thread. The outer peripheral surface of the counterweight An inner concave step is arranged on the lower end of the outer thread, and the step surface of the inner concave step is used to stop and cooperate with the upper end surface of the inner turning edge so as to prevent the counterweight from continuing to move downward. An adh...

Abstract

The invention relates to a gyroscope and a balance ring thereof. The gyroscope comprises the balance ring and a balance weight. The balance ring is provided with an installation hole with an axis extending up and down; the hole wall of the installation hole is provided with internal threads; the periphery of the balance weight is provided with external threads cooperative to the internal threads; and the balance weight is provided with a torque input structure for inputting torque. The internal threads are arranged on the hole wall of the installation hole; the external threads are arranged on the periphery of the balance weight; and the balance weight is in thread connection with the installation hole. During debugging the balance weight, by inputting the torque on the torque input structure of the balance weight, disassembly of the balance weight can be realized easily without causing damages to the balance weight, and the debugging efficiency of the balance weight is increased.

Description

technical field [0001] The invention relates to a gyroscope and a balance ring thereof. Background technique [0002] A gyroscope is a device used to sense and maintain direction, which is designed based on the theory that angular momentum is indestructible. The gyroscope mainly consists of a wheel that can rotate on the axis. Once the gyroscope is turned on and rotated, due to the angular momentum of the wheel, the gyroscope tends to resist the direction change. The gyroscope is mostly used in navigation, positioning and other systems. Due to the structure of the power tuning gyroscope itself and the mechanical processing, the balance rings of the flexible joints of the gyroscope are more or less biased to the support centers of the inner and outer flexible rods, so that the flexible joints can rotate at high speeds. In the process, the gimbal swings, which can cause the radial drift error of the gyroscope and affect the accuracy of the gyroscope. Therefore, it is necessar...
