Embodiment Construction
[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0024] Such as Figure 1-3 Shown: a preparation method of a modulation ring, the steps of the preparation method are as follows: a. Process evenly distributed holes on the ring-shaped magnetic permeable material; b. Align the holes on several magnetic permeable materials and stack them up and It is fixed by riveting; c. Pouring or die-casting non-magnetic material into the hole of the magnetic conductive material as the isolation support block, the two ends of the isolation support block respectively protrude from the magnetic material in the axial direction, and the two ends of the isolation support block protrude Each part forms a complete ring; d. Remove the magnetically permeable material at the connection between the inner circle and the outer circle of the isolation support block, so that the two adjacent magnetically permeable blocks are complete...

The invention discloses a method for preparing a modulating ring. The method is characterized by comprising the following steps: (a) processing uniformly distributed holes in ring-shaped magnetic conductive materials; (b) aligning holes in a plurality of magnetic conductive materials, then, stacking the magnetic conductive materials, and fixing the magnetic conductive materials; (c) casting or die-casting non-magnetic-conductive materials in the holes of the magnetic conductive materials, and carrying out forming so as to obtain isolating supporting blocks; (d) removing the magnetic conductive materials from inner circle and outer circle connected positions of the isolating supporting blocks so as to completely disconnect every two adjacent magnetic regulating blocks, and arranging the isolating supporting blocks and the magnetic regulating blocks in a spaced manner so as to form the ring-shaped modulating ring. According to the method disclosed by the invention, processed ring-shaped magnetic conductive materials are of integers, the work of stacking a large number of magnetic conductive materials is avoided, and the overall roundness of the modulating ring made up of the isolating supporting blocks and the magnetic regulating blocks can be guaranteed; meanwhile, resin materials such as epoxy glue are replaced with cast aluminum or injection molded structures as the isolating supporting blocks, so that the improvement on the overall rigidity of the modulating ring is facilitated, and the heat dissipation can be improved.
Description
technical field [0001] The invention relates to the technical field of permanent magnet motors, in particular to a method for preparing a modulation ring based on the magnetic field modulation principle. Background technique [0002] The modulation ring is the core component of the magnetic gear and the permanent magnet compound motor based on the modulation principle, and has broad prospects in the fields of wind power generation, air-cooled island system, and electric vehicles. The existing modulation ring design and manufacturing process is difficult to mass-produce due to processing and assembly difficulties; the use of resin materials such as epoxy glue for fixing makes the modulation ring poor in rigidity and difficult to dissipate heat, so it can only be used in low-power magnetic gears and composite On the motor, it cannot meet the market demand. Contents of the invention [0003] The purpose of the present invention is to provide a novel, easy-to-implement, high ...
