Abstract

본 발명은 내연기관의 크랭크축에 체결되는 스러스트베어링에 관한 것으로서, 축방향으로 움직이는 유격을 줄여 진동과 소음이 저감되도록 하기 위해, 오일구멍이 형성되는 베어링하우징(12)과 크랭크축(10)의 저널(11) 사이에 장착되는 것으로서, 일측면에 상기 베어링하우징(12)의 오일구멍 보다 크게 요흠부가 형성되고, 반대쪽 측면에 내주연과 외주연으로 이어지게 요흠이 형성되며, 상기 일측면의 요흠부와 반대 측면 요흠에 연통되게 오일구멍(21)이 형성되어, 베어링하우징(12)에서 압송되는 오일이 스러스트베어링(20) 일측면의 요흠부를 가압하게 되고, 일측면 요흠부로 이송된 오일이 스러스트베어링(20)의 오일구멍(21)을 통해 타측면의 요흠으로 이송되며, 타측면으로 이송된 오일이 방사형으로 형성된 요흠의 상부와 하부로 분리되어 송출되도록 하여, 스러스트베어링(20) 일측면의 요흠부가 오일에 의해 계속적으로 압력을 받게 되어, 크랭크축(10)의 저널(11) 끝에 밀착되도록 하는 내연기관용 크랭크축의 유압밀착식 스러스트베어링이다.The present invention relates to a thrust bearing fastened to a crankshaft of an internal combustion engine, and to reduce vibrations and movements in the axial direction so as to reduce vibration and noise, an oil hole is formed in a bearing housing (12) and a crankshaft (10). It is mounted between the journals 11, the recessed portion is formed on one side larger than the oil hole of the bearing housing 12, the recessed portion is formed on the opposite side to lead to the inner and outer circumference, the recessed portion of the one side The oil hole 21 is formed to communicate with the side recesses opposite to each other, so that the oil pressurized by the bearing housing 12 presses the recesses on one side of the thrust bearing 20, and the oil transferred to the recesses on one side is thrust bearing. It is conveyed to the other side of the grooves through the oil hole 21 of the 20, so that the oil transferred to the other side is separated into the upper and lower portions of the grooves formed radially and sent out. Thus, the recessed portion of one side of the thrust bearing 20 is continuously pressurized by oil, and is a hydraulically-adhered thrust bearing of the crankshaft for the internal combustion engine which is brought into close contact with the journal 11 end of the crankshaft 10.
