Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] like figure 1 , 2 , 3, and 4, the small flexible joint is made of integral elastic material, and its structure includes three parts: an upper ring 101, a balance ring 102 and a lower ring 103. The adjustment ring 102 is a cylindrical structure, and the inside is used to place and adjust the balance Four pairs of through-holes 104 are evenly distributed on the outer wall of the balance ring 102, each pair of through-holes are distributed at 90 degrees to each other, and the diameter of each through-hole is Φ3mm. like Figure 5As shown, the four pairs of through holes 104 are respectively the first through hole 401, the second through hole 402, the third through hole 403, the fourth through hole 404, the fifth through hole 405, the sixth through hole 406, and the seventh through hole 407. The eighth through hole 408, wherein t...

Abstract

The invention relates to a small-sized integral type flexible joint and a minitype high-speed dynamic tuned gyroscope. The small-sized integral type flexible joint is made of an elastic material, has small volume and simple structure, prevents a welding link of an inner flexible joint and an outer flexible joint and enhances the processing precision of the flexible joint. The minitype high-speed dynamic tuned gyroscope formed by the small-sized integral type flexible joint is in a dumbbell type symmetrical structure, one end of the minitype high-speed dynamic tuned gyroscope is a gyroscope rotation part, the other end of the same is a driving motor part, the gyroscope rotation part is connected with the driving motor part by the small-sized integral type flexible joint, thereby reducing the volume of the dynamic tuned gyroscope and enhancing resistance of the gyroscope against mechanical environment and improving the measuring precision of the gyroscope.

Description

technical field [0001] The invention relates to a small-sized integral flexible joint and a miniature high-speed dynamic gyroscope composed of the integral flexible joint. The dynamic gyroscope can be used to detect the angular velocity and angle increment of a moving carrier, and can be used as a Attitude Sensitive Devices. Background technique [0002] The flexible joint is the key part of the dynamic adjustment gyroscope, also known as the flexible support, which is composed of a balance ring, a pair of inner flexible rods and a pair of outer flexible rods. The inner flexible rod connects the gyroscope balance ring with the drive shaft , the outer flexible rod connects the gimbal to the rotor. The flexible joint transmits the rotational torque added by the drive shaft to the gyro rotor, so that the gyro rotor has a degree of freedom of rotation around the inner and outer torsion bars, and the dynamic compensation torque generated by the balance ring can offset the positi...
