Abstract

본 발명은 전동기의 소음제거 방법에 관한 것임. 종래에는 회전축을 금속으로 만든 볼 베어링 또는 저널등으로 지지시켰었기 때문에 금속성 소음이 발생하고, 마모가 심하여 주시적으로 지지수단을 교체해주어야 하는 문제점이 있었음. 본 발명은 회전축(2)을 링형영구자석 (4)과 회전축(2)간의 자력에 의한 반발력으로 공중에 띄우고, 회전축 (2)과 영구자석 (4) 사이에는 고강도 고무밀봉링 (5)을 끼워 넣어서 회전축 (2)을 기계적 마찰없이 회전될수 있도록한 전동기의 소음제거방법임. 본발명에 의한 소음제거방법은 전동기의 정숙한 운전과 우수한 내구성을 나타내는 장점이 있음.The present invention relates to a noise reduction method of an electric motor. Conventionally, since the rotating shaft was supported by metal ball bearings or journals, there was a problem in that the metallic noise was generated and the abrasion was severe and the support means had to be replaced. The present invention floats the rotating shaft (2) in the air by the repulsive force by the magnetic force between the ring-shaped permanent magnet (4) and the rotating shaft (2), between the rotating shaft (2) and the permanent magnet (4) sandwiching a high-strength rubber sealing ring (5) The noise reduction method of the motor which puts the rotating shaft (2) to be rotated without mechanical friction. Noise reduction method according to the present invention has the advantages of quiet operation and excellent durability of the motor.

Claims (1)

전동기(1)의 회전축(2)이 관통하는 축받이(3)에, 이 축받이(3)로 부터 회전축(2)을 항하여 링형영구자석 (4)과, 고강도고무밀봉링 (5)을 끼워 넣음으로서 링 형영구자석 (4)과 회전축 (2)사이에 자력에 의한 반발력을 작용시켜서 회전축(2)을 금속성 소음을 발생시키지 않으면서 회전될수 있도록 한 것임을 특징으로 하는 전동기 소음제거방법.A ring-shaped permanent magnet 4 and a high-strength rubber sealing ring 5 are inserted into the bearing 3 through which the rotating shaft 2 of the electric motor 1 penetrates from the bearing 3 to the rotating shaft 2. And a repulsive force caused by magnetic force between the ring-shaped permanent magnet (4) and the rotating shaft (2) so that the rotating shaft (2) can be rotated without generating metallic noise. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
