Problems solved by technology
Although the magnetic levitation structure avoids the friction torque generated by frictional contact, there are electromagnetic torque and interference torque generated by conductive hairspring
Moreover, its complex structure and circuit increase the difficulty of assembling and adjusting the entire inertial device, and are not conducive to the miniaturization of the inertial device

Embodiment Construction
[0020] The present invention will be further described below in conjunction with the accompanying drawings.
[0021] Such as figure 1 As shown, the supporting structure of the suspension wire float in this embodiment is composed of three parts: the suspension wire 4 , the positioning piece 3 and the suspension wire clamping mechanism. The suspension wire clamping mechanism includes the suspension wire clamp 2 and the lock nut 1 . The suspension wire 4 is an ultra-precise elastic wire with a diameter of about 0.08mm, the tensile strength is above 1020MPa, and the modulus of elasticity is below 56GPa. Positioning piece 3 is fixed in the groove of hanging wire clamp 2 ends by glue bonding, and the central position is a through hole, and the aperture is slightly larger than hanging wire 4 diameters, and hanging wire 4 can pass therethrough, plays a position-limiting effect. Suspension wire clip 2 is made of high-strength spring alloy, and the end has through groove 6, and groove ...

Abstract
The invention discloses a suspension fiber type float support structure which is positioned at two ends of a float component and consists of a suspension fiber, a positioning piece and a suspension fiber clamping mechanism, wherein the suspension fiber clamping mechanism comprises a suspension fiber clamp and a locking nut; the suspension fiber is an elastic fiber material with the diameter of 0.06-0.10mm; the positioning piece is fixed in a groove at the end part of the suspension fiber clamp; a through hole is formed at the center of the positioning piece; the diameter of the through hole isgreater than the diameter of the suspension fiber; the suspension fiber is threaded through the through hole to realize a limiting effect; a straight slot is formed in the end part of the suspensionfiber clamp; the width of the straight slot is greater than the diameter of the suspension fiber; the suspension fiber can pass through the straight slot; the outer surface of the suspension fiber clamp is arranged in three forms: a cylindrical surface, a threaded connection surface and an outer circular conical surface; the inner surface of the locking nut comprises a threaded connection surfaceand an inner circular conical surface; the inner circular conical surface and the outer circular conical surface are of the same taper; when the locking nut is screwed in, the opening slot of the suspension fiber clamp can be closed to realize a clamping effect on the suspension fiber. The suspension fiber type float support structure disclosed by the invention has the advantages of small frictionmoment, high positioning precision, simple structure and easiness in assembly and adjustment.
Description
technical field [0001] The invention relates to a support structure for a liquid-floating inertial device, in particular to a wire-suspension support structure used at both ends of a float assembly in the liquid-floating inertial device for auxiliary support and axis fixing. Background technique [0002] Liquid-floating inertial devices include liquid-floating gyroscopes and liquid-floating accelerometers, both of which use liquid-floating support technology. The liquid with a certain viscosity is filled between the float assembly and the shell. After precision design, the average density of the float assembly Equal to the liquid density, the float assembly is in a state of full suspension. In the liquid-floating inertial device, the floating liquid only plays the role of unloading the gravity of the float assembly, and cannot play the function of fixing the axis. When the carrier is overloaded or the temperature changes, the float assembly will deviate from the equilibrium ...
