A High Stiffness Spherical Lorentz Deflection Bearing With Auxiliary Air Gap

Abstract

A high-rigidity spherical Lorentz deflection bearing with an auxiliary air gap, including a rotor system and a stator system. The rotor system includes: a mounting sleeve, an auxiliary magnetic steel, a magnetic sleeve, a magnetic isolation ring, a trapezoidal spherical magnetic steel, and a spherical paramagnetic Ring, trapezoidal spherical magnetic steel washer, mounting sleeve lock nut, component lock nut and rotor turntable; the stator system includes: stator skeleton, winding and epoxy resin glue; there are auxiliary air gaps and air gaps in the stator / rotor system. The invention connects double-circle auxiliary magnet steel and four-circle main magnet steel in series in the magnetic circuit circuit, thereby improving the magnetomotive force of the magnetic circuit circuit. At the same time, two auxiliary air gaps are added next to the double-turn auxiliary magnets, so that most of the magnetic flux of the main magnetic circuit passes through the auxiliary air gaps to form a loop, which reduces the reluctance of the magnetic circuit loop and improves the magnetomotive force of the four-turn main magnets. Utilization, thereby increasing the air gap magnetic density and suspension stiffness.

Description

technical field [0001] The invention relates to a non-contact magnetic suspension bearing with an auxiliary air gap, in particular to a high-rigidity spherical Lorentz deflection bearing capable of high dynamic control for a stable suspension platform. Background technique [0002] The inertial stabilization platform uses inertial measurement devices to detect the attitude information of the platform mover in real time, isolates various disturbances such as attitude changes of carriers (aircraft, ships, spacecraft, etc.), external impacts, and precisely controls the attitude of the load. According to different support methods, inertial stabilized platforms can be divided into four categories: mechanical, air-floating, liquid-floating, and magnetic levitation. Due to the advantages of simple structure and mature technology, mechanically stabilized platforms are widely used in remote sensing observation fields such as satellites, aircraft, and ships. However, the inevitable fr...

Problems solved by technology

However, the series configuration of the magnets not only increases the magnetomotive force of the magnetic circuit, but also increases the reluctance of the entire magnetic circuit circuit, reducing the utilization rate of the magnetomotive force of the original two-sided four-turn magnet and the auxiliary magnet. , making the effect of bearing stiffness improvement unsatisfactory
