Abstract

본 발명은 캔드 전동기의 이물질 끼임 방지장치에 관한 것으로, 회전자 조립체(2) 지지용 트러스트 베어링(4)을 잡아주는 고무홀더(5)의 부하측면에 원심 수류를 형성하여 유속을 증가시키기 위한 복수개의 회전날개(5a)를 형성하여 베어링(3)와 회전자 축(10)사이에 이물질이 끼임을 방지하도록 구성되어 있다. 이러한 본 발명은 펌프 운전시 고무 홀더(5)의 회전날개(5a)에 의해 형성되는 원심 수류에 의하여 베어링(3)과 회전자 축(10) 사이로 들어오는 물의 유속을 빠르게함으로써 베어링(3)과 회전자 축(10) 사이에 이물질이 끼이거나 침적되는 현상을 방지하도록 되어 있으므로 전동기의 기동이 불가능하게 되는 결함을 해소하여 제품의 신뢰성을 향상하는 이점이 있다.The present invention relates to a foreign matter pinch prevention device of the canned motor, to form a centrifugal flow on the load side of the rubber holder (5) for holding the thrust bearing (4) for supporting the rotor assembly (2) to increase the flow rate The rotor blades 5a are formed to prevent foreign matter from being caught between the bearing 3 and the rotor shaft 10. The present invention is to speed up the flow rate of water flowing between the bearing 3 and the rotor shaft 10 by the centrifugal flow formed by the rotary blades 5a of the rubber holder 5 during the pump operation, and the bearing 3 and Since the foreign matter is caught or deposited between the electronic shaft 10, there is an advantage to improve the reliability of the product by eliminating the defect that the motor is impossible to start.
