댐퍼풀리 시험장치{apparatus for testing a damper pulley}Damper pulley {apparatus for testing a damper pulley}

본 발명은 댐퍼풀리 시험장치에 관한 것이다.The present invention relates to a damper pulley test apparatus.

댐퍼풀리는 도 1에 도시된 바와 같이 중앙에 허부(10), 외주부에 진동링(20) 그리고 상기 허브와 진동링 사이에 개재된 고무(30)를 가황처리하여 이들을 일체로 포함하고 있다.As shown in FIG. 1, the damper pulley vulcanizes the rubber part 30 interposed between the hub 10, the outer circumferential part 20, and the hub and the vibration ring at the center thereof, and includes them integrally.

종래에는 진동링(2)을 고정시키고 허브(10)를 복수회 일정각도 비틀어서 진동링(20)과 허브 사이에 개재된 고무(30)의 내구성을 측정하는 방식으로 댐퍼풀리를 테스트하였다.Conventionally, the damper pulley was tested by measuring the durability of the rubber 30 interposed between the vibration ring 20 and the hub by fixing the vibration ring 2 and twisting the hub 10 a plurality of times.

하지만, 이러한 측정방식은 고무가 균열이 발생되기 전에 허브와 고무 사이 그리고 진동링과 고무 사이의 접착이 해제되어 버려 제대로 고무의 내구성을 측정할 수 없었다.However, this measurement method was unable to properly measure the durability of the rubber because the adhesion between the hub and the rubber and between the vibration ring and the rubber was released before the rubber cracked.

본 발명은 상기된 문제점을 해결하고자 안출된 것으로서, 고무에 방사상 안쪽으로 부하를 준 상태에서 고무에 비틀림 부하를 줄 수 있는 댐퍼풀리 시험장치를 제공하는 것을 목적으로 한다.The present invention has been made to solve the above problems, and an object of the present invention is to provide a damper pulley test apparatus that can give a torsional load to the rubber in a state in which the rubber is radially inwardly loaded.

본 발명은 테스트할 댐퍼풀리를 구동축과 함께 회전할 수 있도록 구동축에 장착하고 이 댐퍼풀리에 종동하여 회전하는 종동축을 벨트에 의해 구동적으로 연결시킨 상태에서 종동축이 구동축에 대하여 멀어지는 방향 그리고 가까워지는 방향으로 이동시켜서 댐퍼풀리을 방사상으로 가압시킬 수 있는 구조를 댐퍼풀리 시험장치가 구비하게 함으로써, 상기 목적을 달성할 수 있다.In the present invention, the damper pulley to be tested is mounted on the drive shaft so as to rotate together with the drive shaft, and the driven shaft is driven away from the drive shaft in a state in which the driven shaft driven and driven by the damper pulley is driven by a belt. The above object can be achieved by providing the damper pulley test apparatus with a structure capable of moving the damper pulley in a radial direction to pressurize the damper pulley.

더욱이, 본 발명은 상기 구성에 대하여 상기 종동축에 부하를 주는 브레이크를 상기 종동축에 구비하게 할 수도 있다.Furthermore, the present invention can also be provided with a brake on the driven shaft that applies the load to the driven shaft with respect to the above configuration.

상기와 같은 구성에 의해, 본 발명은 고무의 균열에 근거한 내구성을 테스트하는 것을 가능하게 할 뿐만 아니라, 보다 다양한 조건에서 댐퍼풀리의 내구성을 테스트하는 것을 가능하게 한다. With the above configuration, the present invention not only makes it possible to test the durability based on the cracking of the rubber, but also makes it possible to test the durability of the damper pulley under more various conditions.

이하, 본 발명에 따른 실시예의 댐퍼풀리 시험장치를 도 2 및 도 3을 참조하여 설명하면 다음과 같다.Hereinafter, the damper pulley test apparatus according to the embodiment of the present invention will be described with reference to FIGS. 2 and 3.

도 2 및 도 3에는 본 실시예의 댐퍼풀리 시험장치가 도시되어 있다. 2 and 3 show the damper pulley test apparatus of this embodiment.

베이스(1)에는 구동모터(M), 상기 구동모터(M)의 구동력에 의해 구동되는 구동축(2), 상기 구동축(2)과 평행하게 배치되어 상기 구동축(2)의 회전구동력을 전달받아 회전되는 종동축(3)이 탑재되어 있다.The base 1 is disposed in parallel with a driving motor 2, a driving shaft 2 driven by the driving force of the driving motor M, and the driving shaft 2, and is rotated by receiving a rotational driving force of the driving shaft 2. The driven shaft 3 to be mounted is mounted.

상기 구동축(2)의 일측에는 테스트될 댐퍼풀리(P)의 허브(10)가 장착되어 상기 구동축(2)과 함께 회전하게 되고, 상기 종동축(3)의 일측에는 종동풀리(4)가 고정적으로 외접되어 상기 종동축(3)과 함께 회전하게 된다.The hub 10 of the damper pulley P to be tested is mounted on one side of the drive shaft 2 to rotate together with the drive shaft 2, and the driven pulley 4 is fixed to one side of the driven shaft 3. It is circumscribed to rotate with the driven shaft (3).

상기 종동풀리(4)와 상기 댐퍼풀리(P) 간에는 벨트(V)에 의해 연결되어 상기 댐퍼풀리(P)가 회전하게 되면, 이에 종속하여 상기 종동풀리(4)도 함께 회전하게 된다.When the damper pulley P is connected between the driven pulley 4 and the damper pulley P and the damper pulley P rotates, the driven pulley 4 also rotates in dependence thereon.

상기 종동축(3)과 상기 베이스(1) 사이에는 선형 가이드 레일(L)이 개재되어 있으며, 이 선형 가이드 레일(L)을 따라 상기 종동축(3)은 상기 구동축(2)에 대하여 멀어지는 방향 및 가까워지는 방향으로 이동될 수 있다.A linear guide rail (L) is interposed between the driven shaft (3) and the base (1), and the driven shaft (3) moves away from the drive shaft (2) along the linear guide rail (L). And in a direction that is approaching.

상기 종동축(3)은 상기 에어실린더(A)의 로드(R) 선단에 접속되어 있어서, 로드(R)가 전진하게 되면, 상기 종동축(3)은 상기 선형 가이드 레일(L)을 따라 상기 구동축(2)에 대하여 멀어지는 방향으로 이동되고, 로드(R)가 후퇴하게 되면, 상기 선형 가이드 레일(L)을 따라 상기 구동축(2)에 대하여 가까워지는 방향으로 이동될 수 있다. 따라서, 로드(R)의 전진/후퇴량에 따라 벨트(V)에 의한 댐퍼풀리(P)의 방사상 가압량이 달라지게 된다.The driven shaft 3 is connected to the front end of the rod R of the air cylinder A. When the rod R is advanced, the driven shaft 3 follows the linear guide rail L. When the rod R is moved away from the drive shaft 2 and the rod R is retracted, the rod R may move along the linear guide rail L in a direction closer to the drive shaft 2. Therefore, the radially pressurized amount of the damper pulley P by the belt V varies according to the forward / retracted amount of the rod R. FIG.

또한, 상기 종동축(3)의 타측에는 공지의 마찰식 브레이크(B)가 배치되어 상 기 마찰식 브레이크가 상기 종동축에 대하여 선택적으로 그리고 접촉력을 달리하여 접촉되게 되어 있으며, 상기 마찰식 브레이크(B)가 상기 종동축(3)과 접촉하게 되면, 상기 종동축(3)이 부하를 받게 되어 회전속도가 감소하게 되고, 이에 따라 상기 종동축(3)과 상기 구동축(2) 간의 회전속도가 차이가 나게 되어, 결국 상기 댐퍼풀리(P)에 회전속도 차이만큼의 부하가 전달되게 된다.In addition, a known friction brake (B) is arranged on the other side of the driven shaft (3) so that the friction brake is brought into contact with the driven shaft selectively and with different contact forces, and the friction brake ( When B) comes into contact with the driven shaft 3, the driven shaft 3 is subjected to a load, thereby reducing the rotational speed. Accordingly, the rotational speed between the driven shaft 3 and the drive shaft 2 is increased. As a result, a load corresponding to the difference in rotational speed is transmitted to the damper pulley P.

본 실시예의 댐퍼풀리 시험장치는 로드의 전진/후퇴량에 따라 그리고 종동축에 대한 마찰식 브레이크의 접촉력에 따라, 다양한 조건을 주어서 댐퍼풀리의 허브와 진동링 사이에 개재된 고무의 균열에 따른 내구성을 측정가능하게 한다. The damper pulley test apparatus of the present embodiment has various conditions depending on the forward / retract amount of the rod and the contact force of the friction brake on the driven shaft, and the durability according to the crack of the rubber sandwiched between the hub and the vibration ring of the damper pulley. Make measurable.
