Problems solved by technology

[0003] Magnetic gears generally consist of an outer rotor, an inner rotor, and a modulating ring. At present, the manufacturing process of the outer rotor and the inner rotor is relatively simple, but the manufacturing process of the modulating ring is relatively troublesome, mainly because the assembly structure of the modulating ring is relatively complicated. Therefore, if it can be effectively The assembly structure of the optimized modulation ring means that the overall production efficiency of the magnetic gear can be improved
In addition, as an important component of the magnetic gear, the modulation ring must have good rigidity and integrity, and the current modulation ring still needs to be strengthened

Abstract

The invention discloses a magnetic gear structure capable of improving the production efficiency, and relates to a magnetic gear structure. An outer rotor rotates outside a modulating ring, an inner rotor rotates inside the modulating ring, the modulating ring is a component in the shape of a cylinder formed by folding two sides of an annular plate alternately and repeatedly, each folding openingend communicates with the corresponding end face of a main body component to form a n-shaped folding body, each of two end rings comprises an outer ring, an inner ring and a plurality of limiting plates, the plurality of limiting plates abut against the inner sides of the closed ends of the n-shaped folding bodies of the main body component one by one, the outer ring and the inner ring are coaxially arranged and are overlapped with the main body component, the outer rings and the inner rings are clamped on the inner sides of the corresponding limiting plates respectively, a wedge-shaped mounting groove is formed between the two end rings by each n-shaped folding body, and each magnetic conduction component or non-magnetic conduction component is in interference fit with the corresponding wedge-shaped mounting groove. The modulating ring is efficiently optimized, the production efficiency is improved, and the rigidity and the integrality are guaranteed preferably.

Description

technical field [0001] The invention relates to a magnetic gear structure, in particular to a magnetic gear structure capable of improving production efficiency. Background technique [0002] Compared with traditional mechanical gears, magnetic gears have the advantages of non-contact transmission, no friction loss, low vibration and noise, and long service life, so they are widely used. [0003] Magnetic gears generally consist of an outer rotor, an inner rotor, and a modulating ring. At present, the manufacturing process of the outer rotor and the inner rotor is relatively simple, but the manufacturing process of the modulating ring is relatively troublesome, mainly because the assembly structure of the modulating ring is relatively complicated. Therefore, if it can be effectively The assembly structure of the optimized modulation ring means that the overall production efficiency of the magnetic gear can be improved. In addition, as an important component of the magnetic ...
