Abstract

본 발명은 그리스 보급 간격을 제어하고 베어링의 장수명화가 도모되는 롤링베어링용 밀봉 장치를 제공한다.The present invention provides a sealing device for rolling bearings that controls the grease replenishment interval and allows for a longer service life of the bearing.

본 발명에 의한 롤링베어링용 밀봉 장치는, 윤활되는 롤링베어링(2)의 양측면에 배치되고, 내부에 그리스 충전실을 가지는 베어링 덮개(4a, 4b)를 구비하며, 상기 그리스 충전실은 당해 그리스 충전실을 복수 개의 인접 충전실(5a, 5b)에 간막이 하는 간막이판(13)에 의해 구분되고, 상기 간막이판(13)은 체류를 회피하면서 기유 분리량을 제어하기 위한 각 인접 충전실(5a, 5b)을 중력 방향의 상하로 연통하는 통로(14a, 14b)를 형성하고 있다.The sealing device for rolling bearings according to the present invention is provided on both sides of the rolling bearing 2 to be lubricated, and includes bearing covers 4a and 4b having a grease filling chamber therein, the grease filling chamber being the grease filling chamber. Is divided by a partition plate 13 which is partitioned into a plurality of adjacent charging chambers 5a and 5b, and the partition plate 13 is each adjacent charging chamber 5a and 5b for controlling the amount of base oil separation while avoiding retention. ) Are formed so as to communicate with each other up and down in the gravity direction.
