Description
본 고안은 크랭크 축의 비틀림 진동 뿐 아니라 축방향 진동을 감쇠할 수 있는 구조의 토쇼널 바이브레이션 댐퍼 풀리(Tortional vibration damper pulley)에 관한 것이다.The present invention relates to a tonal vibration damper pulley having a structure capable of damping axial vibration as well as torsional vibration of the crankshaft.
크랭크 축에는 주기적으로 회전력이 작용하므로 비틀림 진동이 발생한다.Torsional vibration occurs due to the periodic rotational force acting on the crankshaft.
이 비틀림 진동은 각 실린더의 크랭크 축의 회전력이 클수록 크랭크 축이 길수록, 또 강성이 작을수록 커진다. 비틀림 진동은 크랭크 축이 어느 회전수가 되면 축 자체의 고유진동과 공간을 일으키고 특히 격심한 진동이 되면 승차감을 나쁘게 할 뿐만 아니라 타이밍 기어나 크랭크 축을 파손하는 원인이 되므로 가능한한 방지하여야 한다.This torsional vibration increases as the rotational force of the crankshaft of each cylinder is larger, the longer the crankshaft and the smaller the rigidity. Torsional vibration should be avoided as much as possible because the crankshaft rotates at a certain speed, causing natural vibration and space of the shaft itself, and especially severe vibration not only makes the ride worse, but also damages the timing gear and the crankshaft.
이 때문에 크랭크 축이 긴 엔진에서는 도 2에 도시하는 것과 같이 토쇼널 바이브레이션 댐퍼라는 비틀림 진동감쇠장치를 크랭크 축 전단의 크랭크 풀리(1)와 일체로 조합시켜 설치하고 있다.For this reason, in the engine with a long crankshaft, as shown in FIG. 2, the torsional vibration damping device called a torque vibration damper is integrally provided with the crank pulley 1 of the front end of a crankshaft.
상기 종래의 토쇼널 바이브레이션 댐퍼는 풀리허브(2)에 댐퍼매스(4)를 특수고무(3)를 개재시켜 접착한 것으로 이 특수고무(3)로 진동을 흡수하도록 되어 있다.The conventional vibration vibration damper is formed by adhering a damper mass 4 to a pulley hub 2 via a special rubber 3 to absorb vibrations with the special rubber 3.
그러나 상기한 바와 같은 비틀림 진동의 감쇠에 의하면 크랭크 축의 회전 방향에 대하여 진동을 흡수하게 될 뿐 축방향의 진동에는 취약하다는 문제점이 지적되고 있다.However, according to the damping of the torsional vibration as described above, it is pointed out that only the vibration is absorbed with respect to the rotational direction of the crankshaft but is vulnerable to the vibration in the axial direction.
이에 본 고안은 상기한 문제점을 감안하여 제단된 것으로서 그의 목적으로 하는 바는 크랭크 축의 회전력의 차이에 따라 회전방향으로 발생하는 비틀림 진동 뿐 아니라 축 방향의 진동을 감쇠할 수 있는 구조의 토쇼널 바이브레이션 댐퍼 풀리를 제공하는 데 있다.Therefore, the present invention has been made in view of the above problems, and its purpose is to provide a vibration damper having a structure capable of attenuating axial vibration as well as torsional vibration occurring in the rotational direction according to the difference in the rotational force of the crankshaft. To provide a pulley.
상기한 목적을 달성하기 위하여 본 고안은 풀리허브에 댐퍼매스를 고무를 개재시켜 접착하여 크랭크 축의 회전 방향으로 작용하는 비틀림 진동을 감쇠하는 댐퍼 풀리에 있어서, 상기 풀리의 측면과 댐퍼 매스 사이에 고무를 부착한 원판형의 금속 플레이트를 개재시켜 접착한 것을 특징으로 한다.In order to achieve the above object, the present invention is a damper pulley for attenuating torsional vibration acting in the rotational direction of the crank shaft by adhering a damper mass to a pulley hub via rubber, wherein a rubber is provided between the side of the pulley and the damper mass. It characterized by adhering through the disk-shaped metal plate attached.

이하 본 고안의 구성과 작용을 첨부한 도면을 참조하여 설명한다.Hereinafter, with reference to the accompanying drawings the configuration and operation of the present invention.
도 1은 본 고안에 의한 토쇼널 바이브레이션 댐퍼 풀리를 나타내는 도면으로 도면 중 부호 1은 크랭크 축의 단부에 정착되어 에어컨 압축기 등을 구동하는 동력을 전달해주기 위한 풀리이며 풀리허브(2)에는 원통형의 고무(3)를 개재하여 댐퍼매스(4)가 접착되어 있다.FIG. 1 is a view illustrating a tonal vibration damper pulley according to the present invention. In the drawing, reference numeral 1 denotes a pulley which is fixed to an end of a crank shaft to transmit power for driving an air conditioner compressor, and a pulley hub 2 has a cylindrical rubber ( The damper mass 4 is bonded through 3).
그리고 풀리(1)의 측면(5)과 댐퍼매스(4)와의 사이에는 고무(6)를 부착한 원판형의 금속 플레이트(7)를 개재시켜 접착되어 있다.And between the side surface 5 of the pulley 1 and the damper mass 4, it adhere | attaches through the disk shaped metal plate 7 with the rubber 6 attached.
이와 같은 본 고안에 의하면 크랭크 축이 일정하게 회전하고 있을 때에는 댐퍼매스(4)는 크랭크 축과 일체로 회전하게 되지만 만일 크랭크 축이 회전 방향에 대하여 정방향 또는 부의 큰 가속도인 비틀림 진동이 발생하였을 때 댐퍼매스(4)는 그대로 일정 속도로 회전을 계속하려고 하기 때문에 중간에 삽입된 고무(3)가 변형되어 이것에 의해 감쇠 작용을 일으키게 된다.According to the present invention, when the crank shaft is constantly rotating, the damper mass 4 rotates integrally with the crank shaft. However, if the crank shaft has a torsional vibration of positive or negative acceleration with respect to the direction of rotation, the damper occurs. Since the mass 4 tries to continue the rotation at a constant speed as it is, the rubber 3 inserted in the middle deforms, thereby causing a damping action.
또한 풀리(1)의 측면에 개재된 고무붙이 금속 플레이트(7)도 상기와 같은 비틀림 진동을 감쇠하는 역할을 하게 될 뿐 아니라 특히 축 방향으로 진동이 발생될 때 고무(6)의 탄성력으로 이를 흡수하게 되므로 본 고안은 비틀림 진동 뿐 아니라 축 방향 진동도 효율적으로 감쇠하게 되는 것이다.In addition, the rubber-plated metal plate 7 interposed on the side of the pulley 1 not only serves to damp the torsional vibration as described above, but also absorbs it by the elastic force of the rubber 6, especially when vibration occurs in the axial direction. The present invention is to effectively damp the axial vibration as well as torsional vibration.
이상과 같은 본 고안에 의하면 풀리의 측면과 댐퍼매스 사이에 고무를 붙인 원판형의 금속 플레이트를 삽입시켜 접착하므로써 댐퍼매스와 풀리허브 사이에 삽입된 원통형의 댐퍼용 고무와 더불어 비틀림 진동을 감쇠시킬 뿐 아니라 크랭크 축 방향으로 작용하는 진동도 흡수하게 되어 승차감을 증진시키고 크랭크 축의 손상을 방지하게 되는 효과가 있다.According to the present invention as described above, by inserting and bonding a disk-shaped metal plate with rubber between the side of the pulley and the damper mass, the torsional vibration is damped together with the cylindrical damper rubber inserted between the damper mass and the pulley hub. In addition, it also absorbs vibrations acting in the crank axis direction, thereby improving ride comfort and preventing damage to the crank shaft.
