한편, 상기 관통홀오일구멍(27)을 통해 상기 관통홀(3)로 공급되는 오일 중 일부는 상기 그루브오일공급구멍(11)을 통해 상기 오일그루브(9)로 공급되는데, 상기 오일그루브(9)로 공급된 오일은 상기 오일그루브(9)의 전체 원주면을 채우면서 상기 베어링바디(5) 전면의 미끄럼면(7)에 충분한 양의 오일이 공급될 수 있도록 하는 역할을 한다.Meanwhile, some of the oil supplied to the through hole 3 through the through hole oil hole 27 is supplied to the oil groove 9 through the groove oil supply hole 11, and the oil groove 9 The oil supplied to) serves to supply a sufficient amount of oil to the sliding surface 7 on the front surface of the bearing body 5 while filling the entire circumferential surface of the oil groove 9.

결과적으로, 상기 베어링바디(5)의 양쪽 미끄럼면(7)들 중 보다 큰 스러스트 하중을 받는 전면의 미끄럼면에는 상기한 바와 같이 관통홀(3)로부터 챔퍼링(25)을 통해 공급되는 오일과 상기 그루브오일공급구멍(11)으로부터 상기 오일그루브(9)를 통해 공급되는 오일이 항상 더욱 원활하고 충분하게 공급되어 유막이 파손되지 않고 안정적으로 확보될 수 있도록 함으로써, 스러스트베어링 자체의 내구성은 물론, 상기 스러스트베어링을 장착한 장치의 내구성과 작동 안정성 및 정숙성을 크게 향상시킬 수 있도록 한다.As a result, in the sliding surface of the front surface subjected to the greater thrust load among the sliding surfaces 7 of the bearing body 5 and the oil supplied from the through-hole 3 through the chamfer 25 as described above. The oil supplied from the groove oil supply hole 11 through the oil groove 9 is always more smoothly and sufficiently supplied so that the oil film can be stably secured without damage, so that the durability of the thrust bearing itself is, of course, It is possible to greatly improve the durability, operational stability and quietness of the device equipped with the thrust bearing.
