Description

선박용 엔진 마운팅{Engine mounting for ship}Engine mounting for ship

본 고안은 선박용 엔진마운팅에 관한 것이다.The present invention relates to a marine engine mounting.

일반적으로 모든 엔진은 피스톤과 커넥팅로드의 상하 운동에 의한 중심 위치의 주기적 변화, 실린더 축방향으로 생기는 왕복운동에 의한 관성력, 커넥팅로드가 크랭크축의 회전에 따라 좌우로 흔들리는 것에 의한 회전관성력 및 크랭크축에 나타나는 뒤틀림의 주기적 변화 등의 현상에 의해 항상 진동이 발생하게 된다.In general, all engines have a periodic change in the center position caused by the vertical movement of the piston and the connecting rod, the inertia force caused by the reciprocating motion in the cylinder axial direction, and the rotational inertia force and crank shaft caused by the connecting rod swinging left and right according to the rotation of the crankshaft. Vibration always occurs due to the periodic change of distortion that appears.

따라서 엔진이 구동할 때 발생되는 진동으로부터 엔진 자체를 보호하고 나아가 진동소음의 발생을 방지하기 위하여 모든 엔진들은 엔진마운팅으로 지지하고 있다.Therefore, in order to protect the engine itself from the vibration generated when the engine is running and to prevent the generation of vibration noise, all engines are supported by the engine mounting.

통상 엔진마운팅은 엔진실의 지지대에 장착되는 베이스와 엔진을 받쳐주는 커버 그리고 사이에 개재되는 완충부재의 구성요소로 이루어져 있으며, 상기한 완충부재는 고탄력을 가지는 고무재로 된 것이 사용되고 있다.In general, the engine mounting is composed of a base mounted on the support of the engine compartment, a cover for supporting the engine, and a component of a shock absorbing member interposed therebetween, and the shock absorbing member is made of a rubber material having high elasticity.

그런데 선박용 엔진은 자동차용 엔진에 비하여 크기도 클 뿐 아니라 무게도 상당히 무겁기 때문에 완충부재는 엔진의 진동을 흡수 및 완화시키는 기능을 보유하고 있어야 될 뿐 아니라 고하중에도 충분히 견딜 수 있는 강도를 지니고 있어야 하는데, 상기한 완충부재가 고탄력의 고무재질로 구성되었다 하더라도 고무재질만으로 구성되었을 경우에는 선박엔진의 고하중을 견딜 수 있는 강도를 보유하지 못하게 되는 취약점을 드러내고 있다.However, since marine engines are not only larger in size but also considerably heavier than automotive engines, the shock absorber must not only have the function of absorbing and mitigating the vibration of the engine, but also must have sufficient strength to withstand high loads. Even if the shock absorbing member is made of a rubber material of high elasticity, when the rubber member is made of only a rubber material, the shock absorbing member exhibits a weakness of not having a strength capable of withstanding the high load of the ship engine.

따라서 본 고안은 선박용 엔진마운팅에 있어 베이스와 커버의 사이에 개재되는 완충부재의 구조를 개선하여 선박 엔진의 고하중에도 견딜 수 있는 강도를 보유하면서 엔진구동시 발생되는 진동을 흡수 완화시키며, 나아가 진동소음의 발생도 방지하는 완충부재를 제공하는데 목적을 두고 고안한 것이다.Therefore, the present invention improves the structure of the shock absorbing member interposed between the base and the cover in the marine engine mounting, while maintaining the strength to withstand the high load of the marine engine to absorb and mitigate the vibration generated during engine operation, furthermore, vibration noise It is designed for the purpose of providing a buffer member to prevent the occurrence of.
