A magnetic gear device with metal foil

Abstract

The invention discloses a magnetic gear device with a metal foil. The magnetic gear device includes an inner yoke, an outer rotor, an outer yoke and an inner rotor, wherein multiple inner rotating permanent magnets are mounted on the inner rotor, multiple outer rotating permanent magnets are mounted on the outer rotor, multiple first mounting slots and multiple connecting slots are defined on theouter rotor, the first mounting slots are in communication with the corresponding connecting slots, a mounting seat is engaged on each of the first mounting slots, and the first mounting slots and themounting seats are all circular. The magnetic gear device is advantaged in that a magnetic gear with the metal foil can reduce fluctuation of the rotational speed of the outer rotor in the transmission process of the inner rotor, stability of the rotational speed is enhanced, fluctuation of the output torque is reduced, the magnitude of the magnetic flux is changed by changing angles between themetal foil and the inner and inner rotating permanent magnets and length, so intensity of magnetic induction is changed, and finally intensity of the magnetic field is enhanced to some extent.

Description

technical field [0001] The invention relates to the technical field of magnetic gears, in particular to a magnetic gear device with metal flakes. Background technique [0002] Gear transmission is the most widely used form of transmission in mechanical transmission. It is mainly used to transmit the rotary motion between two shafts. Traditional disc-mounted gears are integral gears, such as spur gears, helical gears and other different gears. , are integral gears; [0003] However, after long-term work and use of this kind of gear, it is prone to problems such as pitting, gluing, wear, and broken teeth, and is prone to damage. With the continuous development of science and technology, a magnetic gear has appeared at present. The magnetic gear has a simple structure. , no friction, no oil, less maintenance and automatic overload protection, it is a more ideal transmission equipment than traditional gears. [0004] The existing magnetic gears generally cannot satisfy the rel...

Problems solved by technology

[0003] However, after long-term work and use of this kind of gear, it is prone to problems such as pitting, gluing, wear, and broken teeth, and is prone to damage. With the continuous development of science and technology, a magnetic gear has appeared at present. The magnetic gear has a simple structure. , no friction, no oil, less maintenance and automatic overload protection, it is a more ideal transmission equipment than traditional gears

[0004] The existing magnetic gears generally cannot meet the requirement that the instantaneous speed always maintains the transmission ratio during the transmission process, and the fluctuation of the rotational speed roughly causes the fluctuation of the output torque to be large, which in turn affects the stable transmission of the magnetic gear
