Abstract

The invention provides a magnetism adjusting ring assembly, a magnetic gear and a composite motor. The magnetism adjusting ring assembly comprises a magnetism adjusting ring (1) and a magnetism adjusting ring supporting structure, the magnetism adjusting ring (1) and the magnetism adjusting ring supporting structure are fixedly connected in a sleeved mode, the magnetism adjusting ring (1) comprises salient poles (2) and first grooves (3) which are alternately arranged in the circumferential direction, the magnetism adjusting ring supporting structure comprises a lantern ring (4), protrusions (5) and second grooves (6), the salient poles (2) are embedded into the second grooves (6), and the protrusions (5) are embedded into the first grooves (3). According to the magnetism adjusting ring assembly, the strength and rigidity of the magnetism adjusting ring assembly can be effectively enhanced, the stability of output torque is improved, it is guaranteed that the magnetism adjusting ring assembly effectively outputs large torque, and torque ripple is reduced.

Description

technical field [0001] The present application relates to the technical field of power transmission, in particular to a magnetic adjusting ring assembly, a magnetic gear and a composite motor. Background technique [0002] The concentric magnetic gear is a transmission device used to achieve low speed and high torque. Compared with the traditional variable speed mechanical gear structure, the concentric magnetic gear has the following advantages: 1. The non-contact structure reduces vibration and noise; 2. No lubrication, maintenance-free, high reliability; 3. It has overload self-protection ability. [0003] In the prior art, the magnetic gear is composed of an inner high-speed rotor, an outer low-speed rotor, and a magnetic adjustment ring in the middle of the two, and any one of the inner high-speed rotor, outer low-speed rotor, and magnetic adjustment ring can be fixed to make the other two Rotate, also can three rotate at the same time. The magnetic ring used on the m...

AI Technical Summary

Problems solved by technology

The magnetic ring used on the magnetic gear is usually composed of soft magnetic materials and non-magnetic materials alternately arranged, but in this combination, the soft magnetic materials are generally connected by a very narrow magnetic bridge, or there is no magnetic bridge at all , the non-magnetic material is also independently installed between the soft magnetic materials, which leads to the low strength and rigidity of the magnetic ring structure of this combination, which is prone to deformation, cannot effectively output large torque, and will reduce the output torque The stability of the motor increases the torque fluctuation, which has a great impact on the occasions that require smooth operation
