Concentric permanent magnetic gear magnetism regulation ring device and production method thereof

Abstract

The invention discloses a concentric permanent magnetic gear magnetism regulation ring device and a production method thereof. The device comprises a magnetism regulation pole piece, support pins, a left end ring, a right end ring, a left end nut and a right end nut, wherein the magnetism regulation pole piece is connected with the left end ring and the right end ring as a whole through the support pins, the left end nut and the right end nut respectively. In the invention, the traditional technology is adopted for processing and production; and in comparison with the casting method commonly adopted at home and abroad, the traditional technology has the advantages that the production period is short, the production cost is low, the processing precision is easy to guarantee, and the like. The support pins are of a columnar structure and are uniformly distributed along the circumferential direction of the magnetism regulation ring; and compared with a rectangular or I-shaped structure, the precision and rigidity of the whole structure of the magnetism regulation ring are improved. The circumferential through-hole fit between the support pins and the magnetism regulation pole piece is the simplest and most common hole-shaft fit in the machining technology, so that the processing and assembly are convenient, and the positioning precision and stability among the parts of the magnetism regulation pole piece are promoted.

Description

technical field [0001] The invention relates to a permanent magnet gear transmission device, in particular to a magnetism regulating ring device of a concentric permanent magnet gear. Background technique [0002] The concentric permanent magnet gear is composed of three layers of concentric rotors, such as a low-speed rotor, a flux-adjusting ring and a high-speed rotor. It is composed of supporting pole pieces (generally non-metallic materials such as polymers) whose rate is close to vacuum. It is a typical composite whole composed of different materials, and it is difficult to manufacture it by traditional methods. [0003] At present, the following two methods are generally used at home and abroad to form: ① After laminating the ferromagnetic magnetic modulation pole piece composed of silicon steel sheets with insulation on both sides, the support pole piece composed of polymer and other non-metallic materials is manufactured by integral casting, and Ensure that the magn...

AI Technical Summary

Problems solved by technology

[0004] The first method requires mold opening, that is, manufacturing molds, so the manufacturing cost is high and the cycle is long, and it is difficult to achieve single-piece small batch production

The magnetism regulating ring formed by the second method has low rigidity, it is difficult to realize integral processing, and the overall processing and assembly accuracy of the magnetism regulating ring cannot be guaranteed
