Title
(EN) SCROLL COMPRESSOR
(KO) 스크롤 압축기
Abstract
(EN) The present invention relates to a scroll compressor, which comprises: a first bearing rotationally supporting a rotary shaft with respect to a casing on one side based on a motor; a second bearing rotationally supporting the rotary shaft with respect to the casing base on the other side based on the motor; and a third bearing rotationally supporting the rotary shaft with respect to a rotating scroll on the opposite side of the first bearing based on the second bearing. Moreover, a distance between the center of the first bearing and the center of the third bearing is formed to be a predetermined distance, and a distance between the center of the motor and the center of the third bearing is farther than a distance between the center of the motor and the center of the first bearing. Furthermore, a distance between the center of the second bearing and the center of the motor is farther than a distance between the center of the second bearing and the center of the third bearing. Accordingly, damage to the second bearing with a weak load condition can be prevented. COPYRIGHT KIPO 2018
(KO) 본 발명은 스크롤 압축기에 관한 것으로서, 모터를 기준으로 일측에서 케이싱에 대하여 회전축을 회전 가능하게 지지하는 제1 베어링; 모터를 기준으로 타측에서 케이싱에 대하여 회전축을 회전 가능하게 지지하는 제2 베어링; 및 제2 베어링을 기준으로 제1 베어링의 반대측에서 선회 스크롤에 대하여 회전축을 회전 가능하게 지지하는 제3 베어링;을 포함하고, 제1 베어링 중심과 제3 베어링 중심 사이 거리가 사전에 결정된 거리로 형성되고, 모터 중심과 제3 베어링 중심 사이 거리가 모터 중심과 제1 베어링 중심 사이 거리보다 길게 형성되고, 제2 베어링 중심과 모터 중심 사이 거리가 제2 베어링 중심과 제3 베어링 중심 사이 거리보다 길게 형성될 수 있다. 이에 의하여, 부하 조건이 열악한 제2 베어링의 파손을 방지할 수 있다.
