Description

자동차의 크랭크 축에 설치된 댐퍼풀리Damper pulley installed on the crankshaft of the car

일반적으로 토크의 변동에 따라 회전축의 비틀림 진동을 흡수하는 장치를 토셔널댐퍼(torsional vibration damper)라 하며, 이는 회전축 주위에 고무댐퍼나 오일댐퍼등을 거쳐 질량이 되는 스틸제의 링을 설치하여 고무의 탄성이나 오일의 점도를 이용하여 비틀림 진동을 흡수하는 것으로, 이에는 크랭크댐퍼나 댐퍼풀리가 있다.In general, a device that absorbs the torsional vibration of the rotating shaft according to the torque change is called a torsional vibration damper, which is formed by placing a ring made of steel that becomes a mass through a rubber damper or oil damper around the rotating shaft. The torsional vibration is absorbed by using the elasticity of the oil and the viscosity of the oil, and there are crank dampers and damper pulleys.

즉, 크랭크 댐퍼는 비틀림 진동을 방지하기 위해 크랭크 축 전단에 부착되 있는 토셔널댐퍼로서, 이는 엔진의 폭발력이나 왕복부의 질량에 의한 관성력이 작용하여 크랭크 축의 토크변동으로 인해 크랭크 축과 공진(共振)하여 발생하는 비틀림 진동을 억제하는 역할을 하고, 댐퍼풀리는 크랭크 축 앞쪽에 설치되어 있는 풀리로서 토셔널 댐퍼와 일체로 만들어져 있는 것이며, 워터펌프나 에어컨의 컴프레서 등을 구동하는 V벨트가 걸리는 풀리가 댐퍼의 플라이 휠에 이용되는 것과 그렇지 못한 것이 있다.In other words, the crank damper is a torsional damper attached to the front of the crankshaft to prevent torsional vibration. The crank damper is in resonance with the crankshaft due to the torque fluctuation of the crankshaft due to the explosion force of the engine or the mass of the reciprocating part. The damper pulley is a pulley that is installed in front of the crankshaft and is integrally formed with the conventional damper, and the pulley that the V-belt that drives the water pump or the compressor of the air conditioner is damped. Are used for flywheels and do not.

이러한 댐퍼풀리를 도 1 을 통해 살펴보면 크랭크 축에 설치되는 축 설치부(12)와 벨트가 설치되는 벨트 설치부(11)가 개별적으로 주조된 후, 비틀림 및 진동을 방지할 수 있도록 축 설치부(12)와 벨트 설치부(11)의 접지면(12a),(11a) 사이에 댐퍼용 고무(13)가 압입되어 형성되어 있는데, 종래에는 상기 댐퍼풀리(10)의 벨트 설치부(11)와 축 설치부(12)가 모두 주조방식으로 제작되어 중량이 무거운 문제점이 있었다.Looking at the damper pulley through FIG. 1, after the shaft mounting part 12 installed on the crankshaft and the belt mounting part 11 on which the belt is installed are individually cast, the shaft mounting part may be prevented from twisting and vibration ( The damper rubber 13 is press-fitted between the ground surface 12a, 11a of the belt mounting portion 11 and the belt mounting portion 11, and the belt mounting portion 11 of the damper pulley 10 is conventionally formed. All of the shaft mounting portion 12 is manufactured by a casting method has a heavy weight problem.

따라서 본 고안의 목적은 상기와 같은 문제점을 해결하기 위한 것으로서, 크랭크 축의 토크변동에 따른 비틀림 진동을 감소시킬 수 있는 댐퍼풀리를 구성하되, 무게를 줄이고 댐퍼풀리의 역할인 비틀림 진동을 더욱 효과적으로 감소시킬 수 있도록 한 자동차 크랭크 축에 설치된 댐퍼풀리를 제공하는데 있다.Therefore, an object of the present invention is to solve the above problems, but to configure a damper pulley that can reduce the torsional vibration caused by the torque change of the crankshaft, to reduce the weight and to more effectively reduce the torsional vibration that is the role of the damper pulley To provide a damper pulley installed on an automotive crankshaft.

It is achieved by integrally forming the one side belt mounting portion with the shaft mounting portion, and forming the other belt mounting portion as a separate body, and then press-fitting the ground surface of the shaft mounting portion with a damper rubber.

이러한 본 고안은 댐퍼풀리의 상단 벨트 설치부가 이분되어 일측 벨트 설치부는 축 설치부와 함께 프레스 형태로 구성되고, 타측 벨트 설치부는 별도로 주조되어 댐퍼용 고무로 축 설치부의 접지면에 압입시켜 구성함에 따라, 벨트 설치부에 형성된 공간부와 프레스 형태로 구성된 일측 벨트 설치부로 인해 댐퍼풀리의 무게를 크게 감소시켜 제조원가를 더욱 절감시킬 수 있으므로, 상기 목적을 달성할 수가 있는 것이다.According to the present invention, the upper belt mounting part of the damper pulley is divided into two parts, and one belt mounting part is formed in a press form together with the shaft mounting part, and the other belt mounting part is separately cast and pressed into the ground surface of the shaft mounting part with rubber for damper. Since the belt mounting portion formed in the belt mounting portion and the space portion formed in the press form greatly reduces the weight of the damper pulley, it is possible to further reduce the manufacturing cost, thereby achieving the above object.
