Description

압축기용 풀리 댐퍼 어셈블리{DAMPER ASSEMBLY OF PULLY FOR COMPRESSOR}Pulley damper assembly for compressor {DAMPER ASSEMBLY OF PULLY FOR COMPRESSOR}

본 고안은 압축기용 풀리 댐퍼 어셈블리에 관한 것으로서 더욱 상세하게는 엔진의 동력이 압축기로 전달하는 과정에서 발생하는 충격을 완화하면서 동력을 전달하는 벨트의 손상을 방지할 수 있도록 개선한 댐퍼 어셈블리의 제공에 관한 것이다.The present invention relates to a pulley damper assembly for a compressor, and more particularly, to provide a damper assembly that is improved to prevent damage to a belt that transmits power while mitigating an impact generated during a process of transmitting power of an engine to a compressor. It is about.

통상적으로 클러치리스 압축기는 클러치를 가지고 엔진의 동력을 선택적으로 절환시켜 필요 시 작동시키는 일반적인 압축기와는 달리 엔진으로부터 전달되는 동력을 절환 시키기 위한 클러치가 없는 상태로 구비된다.Typically, the clutchless compressor is provided with a clutch without a clutch for switching the power transmitted from the engine, unlike a general compressor having a clutch and selectively switching the power of the engine to operate when necessary.

즉, 엔진의 시동과 함께 엔진의 동력을 전달받아 상시 회전하는 가변용량 타입의 압축기에 많이 사용된다.That is, it is used in a variable capacity type compressor that rotates at all times by receiving power of the engine along with starting the engine.

종래 기술이 적용되는 압축기용 풀리 댐퍼의 구성을 도 4를 통하여 살펴보면 다음과 같다.Looking at the configuration of a pulley damper for a compressor to which the prior art is applied as follows.

압축기(1)의 구동축(2) 선단부에 드라이버플레이트(3)를 단속하고, 상기 드라이버플레이트(3)의 외측 가장자리는 압축기(1)의 실린더블럭(4) 선측에 베어링(5)으로 유지되어 엔진의 동력을 벨트(6)로 연결되어 전달받는 풀리(7)의 외 면과 볼트(8)로 고정하고 있다.The driver plate 3 is interrupted at the distal end of the drive shaft 2 of the compressor 1, and the outer edge of the driver plate 3 is held as a bearing 5 at the side of the cylinder block 4 of the compressor 1 so as to maintain the engine. It is fixed by the bolt (8) and the outer surface of the pulley (7) that is connected to the power of the belt (6).

상기와 같은 종래 기술의 클러치리스 압축기에 적용되는 풀리는 압축기에 이상이 없을 경우에는 특별한 문제가 없으나, 압축기 내의 부품이 고착되는 현상이 발생하여 과부하가 발생할 경우에는 엔진의 동력을 전달하는 벨트가 미끄러지면서 마찰이 일어나게 된다.When the pulley applied to the clutchless compressor of the prior art as described above does not have any problem in the compressor, there is no particular problem. However, when the overload occurs due to the phenomenon that the components in the compressor are stuck, the belt transmitting the power of the engine slides. Friction will occur.

이와 같이 벨트가 풀리와 마찰을 일으킬 경우에는 고열에 의한 화재의 위험이 높은 것은 물론, 압축기를 구성하는 각 부품에 무리를 주어 압축기 전체를 손상시키게 되는 원인이 된다.In this way, when the belt causes friction with the pulley, the risk of fire due to high heat is high, and the parts of the compressor constituting the compressor may be overwhelmed to damage the entire compressor.

특히, 벨트가 손상되거나 끊어질 경우에는 엔진의 동력을 전달받아 회전하는 발전기, 조향펌프 등과 같은 모든 부품의 동작이 정지되기 때문에 자동차가 주행 중 갑자기 정지하게 되거나 제어가 곤란하게 되므로 치명적인 위험을 초래할 수 있다.In particular, when the belt is damaged or broken, all parts such as the generator, steering pump, etc., which are rotated by the power of the engine, are stopped. Therefore, the vehicle suddenly stops or becomes difficult to control while driving. have.

상기와 같은 문제를 해결하기 위하여 클러치리스 압축기 작동시 발생하는 순간적인 충격을 흡수할 수 있도록 규정 이상의 부하 발생시 엔진의 동력이 압축기로 전달되는 것을 차단할 수 있도록 드라이버플레이트에 파단홈을 형성하여 사용하게 된다.In order to solve the above problems, a breakdown groove is formed in the driver plate so that the engine power can be prevented from being transmitted to the compressor when a load exceeding a prescribed limit is used to absorb the instantaneous shock generated when the clutchless compressor operates. .

이러한 경우에는 압축기 내부의 부품고장으로 인한 고착 현상에 대응하여 엔진의 동력을 전달받는 풀리와 벨트를 안전하게 유지하는 장점은 있으나, 일반적으로 에어컨을 작동시킬 때 발생하는 일시적인 충격현상 또는 자동차가 주행하는 과 정에서 발생하는 외압 등에 대응하지 못하게 된다.In this case, there is an advantage of keeping the pulley and the belt which are powered by the engine safe in response to the seizure due to the failure of the parts inside the compressor. It will not be able to cope with external pressure generated in the tablet.

이와 같이 실제 에어컨 작동시 발생하는 충격에 대응하지 못함으로서 피로 누적에 의하여 시간이 경과함에 따라 압축기의 내구성을 저하시키는 원인이 되고, 풀리와 벨트에도 좋지 않은 영향을 미치게 되는 등 여러 문제점이 발생하고 있는 실정이다.As it does not respond to the shock generated during the operation of the air conditioner, it causes the durability of the compressor as time passes due to the accumulation of fatigue, and adversely affects the pulley and the belt. It is true.

이에 본 고안에서는 상기와 같은 문제점들을 해결하기 위하여 발명한 것으로서 실린더블럭의 크랭크실을 가로지르게 설치하는 샤프트와, 상기 샤프트에 구비하여 압축작동을 수행하는 사판과 슈 및 피스톤, 상기 샤프트의 선단에 고정되는 드라이버플레이트와, 상기 드라이버플레이트는 실린더블럭의 선단에 베어링으로 유지되어 엔진의 동력을 벨트로 전달받는 풀리와 연결되게 구성하는 자동차용 압축기에 있어서;Accordingly, the present invention is invented to solve the above problems, and the shaft is installed across the crank chamber of the cylinder block, and the swash plate and the shoe and piston, which is provided on the shaft to perform the compression operation fixed to the tip of the shaft The driver plate and the driver plate is maintained in the bearing at the tip of the cylinder block is configured to be connected to the pulley for receiving the power of the engine to the belt in the automobile compressor;

상기 풀리와 드라이버플레이트를 고정하는 부위에 충격 흡수를 위한 댐퍼 어셈블리를 더 구비하고, 상기 댐퍼 어셈블리는 풀리의 인너림과 아웃림 사이를 연결하는 아웃플레이트에 형성하는 튜브홀과, 상기 튜브홀에 삽입되어 고정되는 튜브와, 상기 튜브에 드라이버플레이트를 볼트로 고정할 수 있도록 볼트공을 형성하여 삽입되는 고무 또는 우레탄 재질의 댐퍼를 포함하여, 엔진과 외부에서 풀리로 전달되거나 압축기에서 풀리로 전달되는 충격과 진동을 흡수할 수 있도록 하는 것을 목적으로 한다.A damper assembly for shock absorption is further provided at a portion fixing the pulley and the driver plate, and the damper assembly is formed in an out plate connecting an inner rim and an out rim of the pulley, and inserted into the tube hole. And a rubber or urethane damper inserted into a tube to form a bolt hole to fix the driver plate to the tube, and the shock transmitted to the pulley from the engine and the outside or from the compressor to the pulley. It aims to be able to absorb excessive vibration.

본 고안은 평상시 엔진의 동력을 전달받는 과정이나 자동차가 주행하는 과정에서 발생하는 일반적인 충격과 진동은 물론, 에어컨을 작동시킬 때 발생하는 순간적인 충격을 용이하게 흡수하여 완충시켜 압축기의 수명과 내구성에 영향을 미치지 않도록 함으로서 장기간 사용에 따르는 압축기의 성능과 품질을 높일 수 있는 등 다양한 효과를 가지는 고안이다.The present invention easily absorbs and cushions the shock and vibration generated during the operation of the air conditioner as well as the general shock and vibration generated in the process of receiving the engine power or driving the vehicle, thereby improving the life and durability of the compressor. It is designed to have a variety of effects, such as to improve the performance and quality of the compressor according to long-term use by not affecting.

이하 첨부되는 도면과 관련하여 상기 목적을 달성하기 위한 본 고안의 구성과 작용에 대하여 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings will be described the configuration and operation of the present invention for achieving the above object.
