Description

Vibration-proof motor rotor structure

Technical Field

The invention relates to a rotor structure, in particular to an anti-vibration motor rotor structure with simple and reasonable structural design, and belongs to the field of motors.

Background

The existing rotor structure is formed integrally, and the structure has large vibration and noise in the use process, thereby bringing much trouble to users.

Chinese patent publication No. CN208986734U, No. 06, 14, 2019, discloses a utility model named "an anti-vibration external rotor motor". This patent includes rotor, pivot, stator, sleeve pipe, bearing group, end cover, adjusting bolt, ejector pad and axle sleeve, though avoid the vibration through the position of adjustment second bearing and third bearing in order to guarantee the axiality of bearing group, but can not overcome the rotor structure of motor, and the vibration is big, the noise is big in the use, so it still has above-mentioned defect.

Therefore, it is especially necessary to provide a motor rotor structure with simple and reasonable structural design, stability, reliability, convenient assembly and disassembly and low noise.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provides the vibration-proof motor rotor structure which is simple and reasonable in structural design, stable and reliable, convenient to assemble and disassemble and low in noise.

The technical scheme adopted by the invention for solving the problems is as follows: this electric motor rotor structure of vibration-proof type, including magnet one, magnet two, interior iron core, pivot and rotor body, last iron core and the pivot of setting up of rotor body, its characterized in that: the magnet I and the magnet II are connected through the plastic packaging part and then connected with the inner iron core through the vibration damping body; a plurality of claw bodies are uniformly distributed in the plastic package part, and a plurality of tooth bodies are uniformly distributed in the inner iron core.

Preferably, the claw body in the plastic package and the tooth body in the inner iron core are arranged at intervals.

Preferably, the number of the claw bodies and the tooth bodies is four.

Preferably, the vibration damping body of the present invention is made of a rubber material.

Preferably, the plastic package part is made of injection molding materials.

Compared with the prior art, the invention has the following advantages and effects: the whole structure is simple and reasonable in design, the first magnet and the second magnet are connected through the plastic package part and then connected with the inner iron core through the vibration damping body, stability and reliability are achieved, assembly and disassembly are convenient, noise is low, and using requirements are met.
