Description

비틀림 진동흡수용 커플링 댐퍼{Couple damp for tortion vibration}Coupling damper for torsional vibration absorption

본 발명은 디젤발전기에서 발생하는 비틀림진동을 흡수, 저감시킬 수 있는 비틀림 진동흡수용 커플링 댐퍼에 관한 것이다.The present invention relates to a torsional vibration absorption coupling damper that can absorb and reduce torsional vibration generated in a diesel generator.

일반적으로, 도서지역은 육지와 떨어져 있는 관계로 대형 발전설비에서 안정적으로 전력을 공급받지 못하고 도서지역 자체적인 발전설비인 디젤엔진을 설치하여 전력을 공급하고 있다. 고장이 적고 안정적인 육지의 발전설비와는 다르게 디젤엔진은 고장이 빈번하여 사고 발생시 장기간 섬 지역에 전기 공급이 안 되어 도서주민들의 생활에 큰 피해를 주고 있다.In general, the island area is separated from the land, and is not supplied with power stably in large-scale power generation facilities. Instead, the island area supplies diesel power by installing a diesel engine, which is the island's own power generation facility. Unlike on-site and stable land-based power generation facilities, diesel engines suffer from frequent breakdowns and do not provide electricity to island areas for long periods of time.

디젤엔진에서 발생한 비틀림 진동은 종종 엔진 축의 파손을 가져와 장기간 발전정지의 주요 요인이 되고 있다. 도서지역에 많이 설치되고 있는 대형 저속 디젤엔진은 1970년대 오일 쇼크 이후 엔진의 열효율을 증대시키기 위하여 평균유효압력과 최대폭발압력이 꾸준히 증가하여 왔다.Torsional vibrations in diesel engines often lead to engine shaft breakage, which is a major factor in long-term power outages. Large-scale low-speed diesel engines installed in high islands have steadily increased the average effective pressure and the maximum explosion pressure in order to increase the thermal efficiency of the engine since the oil shock of the 1970s.

디젤엔진에서 발생되는 비틀림 진동을 일으키는 기진력도 증가하게 되었고 실린더수가 적은 7실린더 이하는 비틀림 진동의 주 공진점이 상용운전 범위 안에 위치해 있어 공진점을 피하여 운전하는 것이 중요한 요소가 되고 있다.Vibration force that causes torsional vibration generated in diesel engines has also increased, and for less than seven cylinders with few cylinders, the main resonance point of torsional vibration is located within the commercial operation range.

한편, 8실린더 이상의 엔진은 빠른 선속이 요구되어 선박 크기에 비해 고출력의 엔진이 필요하게 되며, 이러한 대형 디젤엔진에서 그 특성에 따라 고성능의 점성댐퍼를 적용하고 있고, 댐퍼의 성능이 떨어지면 크랭크축의 부가응력이 증가하여 절손사고 등 선박의 안전에 지대한 영향을 미칠 수 있다.On the other hand, engines with more than 8 cylinders require fast ship speeds and require high output engines compared to the ship size.In such large diesel engines, high-performance viscous dampers are applied according to their characteristics. Increased stresses can have a significant impact on the safety of ships, such as damage accidents.

그러나, 이러한 점성댐퍼들은 디젤엔진 내부에 설치하기 때문에 댐퍼의 성능 평가가 어렵고, 성능에 문제가 있어도 운전시 교체가 불가능하여 효율면에 있어서 한계가 있었다. However, since the viscous dampers are installed inside the diesel engine, it is difficult to evaluate the performance of the dampers, and there is a limit in terms of efficiency because it is impossible to replace them during operation even if there is a problem in performance.

도서지역에 설치되어 있는 디젤엔진의 주축계는 매우 복잡한 형상의 크랭크축을 비롯하여 몇 단의 축으로 구성되어 있다. 특히 크랭크축은 질량이 분포 하고 있는 복잡한 형상의 탄성체이기 때문에 여기에 외부의 기진력이 작용하면 비틀림 진동을 비롯하여 종진동, 횡진동 및 이들의 연성진동을 일으키게 된다. 특히, 이중에서 비틀림 진동은 디젤엔진의 실용화 단계에서부터 문제가 되어 왔으며 다 실린더 직렬형의 발전기용 디젤기관에 있어 매우 중요한 문제가 되고 있다. 모든 탄성체는 그물체가 가지고 있는 탄성과 질량에 의하여 결정되는 고유진동수를 갖는데 여기에 외력, 예를 들어 연소가스의 압력이나 왕복질량에 의한 관성력 등이 주기적으로 가해지면 이 외력과 같은 진동수의 강제진동을 하게 된다. The main shaft system of a diesel engine installed in an island area consists of several stages, including a crankshaft with a very complicated shape. In particular, because the crankshaft is a complex elastic body in which the mass is distributed, when the external vibration force acts on it, it causes torsional vibration, longitudinal vibration, lateral vibration, and their soft vibration. In particular, the torsional vibration in the double has been a problem since the commercialization stage of the diesel engine and has become a very important problem in the diesel engine for multi-cylinder series type generator. Every elastic body has a natural frequency that is determined by the elasticity and mass of the mesh, and when external force, for example, the pressure of the combustion gas or the inertial force due to the reciprocating mass is applied periodically, the forced vibration of the same frequency as this external force Will be

이러한 고유진동과 강제진동은 서로 독립한 별개의 것이지만 외부에서 가해지는 기진력(exciting force)의 주기가 크랭크축의 주기와 일치하면 공 진(resonance)을 일으키고 각 진폭은 증가하여 축의 응력도 크게 된다. 따라서, 크랭크축 설계에 있어서는 공진이 사용 운전범위 내에서 발생하지 않도록 설계하고 운전 중에는 비틀림 진동을 흡수할수 있는 댐퍼의 개발은 필연적이다.These natural and forced vibrations are independent of each other, but if the period of excitation force applied from the outside coincides with the crankshaft, resonance occurs and each amplitude increases to increase the stress of the shaft. Therefore, in the crankshaft design, it is inevitable to develop a damper that is designed so that resonance does not occur within a used operating range and can absorb torsional vibration during operation.

본 발명의 목적은, 기존의 점성댐퍼가 지닌 문제를 해소하기 위하여 안출된 것으로, 디젤엔진과 발전기 사이에 용이하게 설치하고 범용적으로 적용가능하며, 디젤엔진의 축비틀림 진동을 흡수함과 동시에 디젤발전기의 축손상을 방지할 수 있는 비틀림 진동흡수용 커플링 댐퍼를 제공하는데 있다.An object of the present invention is to solve the problems of the existing viscous damper, it is easily installed between the diesel engine and the generator and can be applied universally, while absorbing the axial torsional vibration of the diesel engine, To provide a torsional vibration absorption coupling damper that can prevent the shaft damage of the generator.

상기한 목적을 달성하기 위하여 본 발명은 엔진의 토크변동 및 회전충격을 보상하기 위한 비틀림 진동흡수용 커플링 댐퍼로서, 엔진축에 연결되고 내측 원주면을 따라 일정 간격으로 복수개의 제1보스부가 구비된 제1허브와, 상기 제1허브와 결합되면서 발전기와 연결되고, 상기 제1보스부와 교차되도록 내측 원주면을 따라 일정 간격으로 복수개의 제2보스부가 구비된 제2허브와, 상기 제1허브의 외주면에 장착되는 커버와, 상기 제1허브의 제1보스부와 상기 제2허브의 제2보스부의 사이에 장착되어 압축스프링 및, 상기 제1허브의 제1보스부와 상기 제2허브의 제2보스부 각각에 장착되어 상기 커버와 접촉하는 탄성접촉수단을 포함한다.In order to achieve the above object, the present invention is a torsional vibration absorption coupling damper for compensating torque fluctuations and rotational impact of the engine, is connected to the engine shaft and provided with a plurality of first boss portion at regular intervals along the inner peripheral surface A second hub coupled to the first hub and coupled to the generator, the second hub having a plurality of second bosses at regular intervals along an inner circumferential surface to intersect the first boss, and the first hub.

본 발명에 따른 비틀림 진동흡수용 커플링 댐퍼에 의하면, 디젤엔진의 축비틀림 진동을 흡수함과 동시에 디젤발전기의 축손상을 방지함으로써 도서지역 디젤발전기의 안전성을 지속적으로 유지할 수 있고, 도서지역의 안정적 전력공급에 기여할 수 있게 된다. 또한, 커플링 댐퍼가 디젤엔진 외부에 용이하게 설치할 수 있으므로 상시적으로 댐퍼의 성능을 평가할 수 있고, 이로 인하여 고장시 교체작업이 용이하게 이루어지게 된다. According to the torsional vibration absorption coupling damper according to the present invention, by absorbing the axial torsional vibration of the diesel engine and preventing the shaft damage of the diesel generator, it is possible to continuously maintain the safety of the diesel generator in the island region, Contribute to the power supply. In addition, since the coupling damper can be easily installed outside the diesel engine, it is possible to evaluate the performance of the damper at all times, thereby facilitating replacement in case of failure.

(실증 실험 결과)(Proven experiment results)

본 실증실험은 한국 전력이 보유하고 있는 도서지역 발전기에 개발된 회전진 동 흡수용 커플링 댐퍼를 설치하여 설치 전. 후 비틀림 진동을 측정하여 진동흡수효과를 측정한 결과로서 에너지흡수효과에 절대적인 인자인 댐핑 크기가 기존의 3%에서 30% 까지 증가되었고, 디젤발전기의 비틀림 진동은 4 mmrad/sec에서 0.25 mmrad/sec로 크게 감소하는 효과를 얻었다.This demonstration test was carried out before the installation and installation of the damping coupling damper developed for the island generators owned by KEPCO. As a result of measuring the vibration absorption effect after measuring the torsional vibration, the damping size, an absolute factor in the energy absorption effect, increased from 3% to 30%, and the torsional vibration of the diesel generator was 0.25 mmrad / sec at 4 mmrad / sec.

본 발명에 따른 커플링 댐퍼는 디젤엔진과 발전기 사이에 용이하게 설치할 수 있고, 디젤엔진의 축비틀림 진동을 90％ 이상 저감할 수 있고, 동시에 디젤발전기의 축손상을 미연에 방지할 수 있게 된다. 또한, 본 발명에 따른 커플링 댐퍼는 댐퍼가 디젤엔진과 발전기 사이에 설치되어 있기 때문에 댐퍼의 상시 성능 관리할 수 있게 된다. 또한 기존의 점성댐퍼에서 문제가 되었던 온도 의존성을 개선하여 특수 마찰재 접촉의 마찰력에 의하여 디젤엔진에서 발생하는 고진동 에너지를 흡수하기 때문에 축손상을 대폭적으로 감소시킬 수 있게 된다.The coupling damper according to the present invention can be easily installed between the diesel engine and the generator, can reduce the axial torsional vibration of the diesel engine by 90% or more, and at the same time prevent the shaft damage of the diesel generator. In addition, the coupling damper according to the present invention, because the damper is installed between the diesel engine and the generator, it is possible to always manage the performance of the damper. In addition, by improving the temperature dependence that has been a problem in the existing viscous dampers, the shaft damage can be greatly reduced because the high vibration energy generated by the diesel engine is absorbed by the frictional force of the special friction material contact.
