Abstract

본 발명은 선박용 구동 유닛에 관한 것으로서, 선박의 모판에 배치된 기어박스(5)와 공통축선을 중심으로 양방향으로 회전하는 두 개의 스크루 프로펠러(77)를 구비한다. 이 스크루 프로펠러(76,77)들은 동심으로 회전하는 두 개의 프로펠러 샤프트(2,6)에 의해 구동되고, 내부 샤프트(2)는 윤활유 공급원을 구비한 두 개 이상의 베어링(14,17)에 지지된다. 내부 샤프트(2)의 베어링들(14,17)은 정지 부시들(15,21)에 의해 샤프트의 회전방향으로 고정적으로 기어박스(5)에 접속된 정지 베어링들로 각각 구성된다. 내부 샤프트 베어링들(14,17)은 베어링 간극의 위치에서 프로펠러 샤프트(2,6)를 향하여 양벽상에 베어링 재료로 피복되는 한편, 정지 부시들의 벽에 배치되어 기어박스로부터 베어링 간극으로 신장하는 하나 이상의 덕트를 통해 윤활유가 상기 베어링들에 공급된다. 베어링 및 이 베어링과 기어박스 사이의 정지 부시는 두 개의 인접부품 사이의 축방향이 서로 작은 각도를 형성할 수 있도록 상호 접속된다. 베어링은 정지 부시내에 드릴가공된 덕트를 통해 기어박스 근방에 배치된 오일펌프에 의해 각가의 베어링의 베어링 폭에 걸쳐 오일이 균일하게 공급되는 동수압 윤활식 베어링의 형태이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drive unit for ships, comprising a gearbox (5) disposed on a mother plate of a ship and two screw propellers (77) rotating in both directions about a common axis. These screw propellers 76,77 are driven by two concentrically rotating propeller shafts 2,6, the inner shaft 2 being supported by two or more bearings 14,17 with a lubricant source. . The bearings 14, 17 of the inner shaft 2 consist of stop bearings connected to the gearbox 5 fixedly in the direction of rotation of the shaft by stop bushes 15, 21, respectively. The inner shaft bearings 14, 17 are covered with bearing material on both walls towards the propeller shafts 2, 6 at the position of the bearing clearance, while one is disposed on the wall of the stop bushes and extends from the gearbox into the bearing clearance. Lubricant is supplied to the bearings through the above duct. The bearing and the stop bush between the bearing and the gearbox are interconnected so that the axial direction between two adjacent parts can form an angle with each other. The bearing is in the form of a hydrostatic lubricated bearing in which oil is uniformly supplied over the bearing width of each bearing by an oil pump arranged near the gearbox through a duct drilled in the stop bushing.
