본 발명은 전자클러치의 풀리에 관한 것으로, 더욱 상세하게는 전자클러치의 단속작용에 의해 엔진의 동력을 압축기에 전달하는데 사용되는 전자클러치의 풀리에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to pulleys of electromagnetic clutches, and more particularly, to pulleys of electromagnetic clutches used to transmit power of an engine to a compressor by an intermittent action of the electromagnetic clutches.

일반적으로 자동차 공기조화장치를 구성하는 압축기는 엔진의 동력으로 구동하면서 증발기로부터 공급되는 냉매를 압축하여 응축기로 보내는 장치로서, 전자클러치의 단속 작용에 의하여 엔진의 동력을 선택적으로 전달받아 구동하도록 설치된다.In general, a compressor constituting an automobile air conditioner is a device that compresses a refrigerant supplied from an evaporator and sends it to a condenser while driving by the power of an engine. .

도 1은 종래에 따른 전자클러치의 단면도이다.1 is a cross-sectional view of a conventional electronic clutch.

도시한 바와 같이 엔진의 크랭크축에 구동벨트(미도시)에 의해 동력적으로 연결되고 그 측면에 마찰면(1a)을 가지는 풀리(1)와, 상기 풀리(1)에 내장되고 압축기의 하우징(4)에 지지됨과 아울러 전원인가에 의해 흡인자속을 발생하는 필드 코일(2)과, 허브(3a)에 의해 압축기의 구동축(4a)과 연결되고, 상기 필드 코일(2)에 의하여 발생되는 흡인자속에 의하여 디스크(3b)가 풀리(1)의 마찰면(1a)에 흡착되어 엔진의 동력을 압축기의 구동축(4a)에 전달하는 디스크 및 허브조립체(3)를 포함하여 이루어진다.As shown, a pulley 1 which is dynamically connected to the crankshaft of the engine by a drive belt (not shown) and has a friction surface 1a on its side, and the housing of the compressor built in the pulley 1 ( A field coil 2 supported by 4) and generating suction magnetic flux by applying power, connected to the drive shaft 4a of the compressor by a hub 3a, and a suction magnetic flux generated by the field coil 2 The disk 3b is attracted to the friction surface 1a of the pulley 1 and includes a disk and hub assembly 3 for transmitting power of the engine to the drive shaft 4a of the compressor.

상기와 같이 구성된 종래의 전자클러치는 필드 코일(2)에 전원이 인가되면 전자코일의 자기유도에 의한 흡인자속에 의하여 디스크(3b)가 크랭크축에 연결된 벨트에 의해 회전하는 풀리(1) 쪽으로 이동하여 그 마찰면이 풀리(1)의 마찰면(1a)에 흡착되어 풀리(1)와 디스크(3b)가 결속됨으로써 벨트를 통해 풀리(1)에 전달된 엔진의 동력을 디스크(3b) 및 허브(3a)를 통하여 압축기 구동축(4a)에 전달하게 된다. The conventional electromagnetic clutch configured as described above moves toward the pulley 1 in which the disk 3b is rotated by a belt connected to the crankshaft by the magnetic flux induced by the magnetic induction of the electromagnetic coil when power is applied to the field coil 2. The friction surface is attracted to the friction surface 1a of the pulley 1, and the pulley 1 and the disk 3b are coupled to each other so that the engine power transmitted to the pulley 1 through the belt is transmitted to the disk 3b and the hub. It is transmitted to the compressor drive shaft 4a through 3a.

그리고, 전자코일에 대한 전원이 차단되면 탄성부재(3c)의 탄성 반발력에 의하여 디스크(3b)가 풀리(1)의 마찰면(1a)으로부터 이간됨으로써 엔진 동력이 압축기의 구동축(4a)에 전달하는 것을 중단한다. When the power to the electromagnetic coil is cut off, the disk 3b is separated from the friction surface 1a of the pulley 1 by the elastic repulsive force of the elastic member 3c, so that the engine power is transmitted to the drive shaft 4a of the compressor. Stop it.

이와 같이 압축기용 전자클러치는 전원인가 여부에 따라 엔진의 동력을 압축기에 전달 혹은 차단한다.In this way, the electromagnetic clutch for the compressor transmits or blocks the power of the engine to the compressor depending on whether the power is applied.

도 2 및 도 3은 종래에 따라 전자클러치의 풀리를 상세히 나타낸 도면이다.2 and 3 are views showing in detail the pulley of the electronic clutch according to the prior art.

도시한 바와 같이 전자클러치의 풀리(1)는 압축기의 구동축이 결합되는 베어링이 내부에 개재된 로터부(1a)와, 상기 로터부(1a)의 동축상에 일정 간격을 두고 배치되고, 외주면에 벨트홈이 형성된 풀리부(1b)와, 상기 로터부(1a)와 풀리부(1b)의 일측면에 동심축으로 일정간격의 슬롯(1d)을 형성시켜 마찰면을 이루도록 하는 페이스(1c)로 구성되어 있다.As shown in the drawing, the pulley 1 of the electromagnetic clutch is disposed at regular intervals on the coaxial axis of the rotor portion 1a and the rotor portion 1a interposed therein with a bearing to which the drive shaft of the compressor is coupled, and on the outer circumferential surface thereof. A pulley portion 1b having a belt groove formed therein, and a face 1c for forming a friction surface by forming slots 1d at regular intervals concentrically on one side of the rotor portion 1a and the pulley portion 1b. Consists of.

상기와 같이 구성된 종래의 전자클러치의 풀리는 풀리부(1b), 로터부(1a) 및 페이스(1c)를 단조작업에 의해 일체로 드로잉 가공하여 필드코일 이 수납되는 공간부(1e)을 형성하고, 상기 로터부(1a)의 내측에 베어링(5)을 압입시킨 상태에서 베어링(5)의 이탈을 방지하도록 코킹(6) 작업을 하게 된다.The pulley of the conventional electronic clutch configured as described above integrally draws the pulley 1b, the rotor 1a and the face 1c by a forging operation to form a space 1e in which the field coils are stored. In the state in which the bearing 5 is press-fitted to the inside of the rotor part 1a, the caulking 6 is performed to prevent the bearing 5 from being separated.

그러나, 상기와 같이 구성된 종래의 전자클러치의 풀리의 로터부(1a)에 결합되는 베어링(5)은 기존 규격품을 사용함으로, 수명 연장에는 일정한 한계가 있는 문제점이 있다. However, since the bearing 5 coupled to the rotor portion 1a of the pulley of the conventional electronic clutch configured as described above uses an existing standard product, there is a problem that there is a certain limit in extending the life.

즉, 베어링(5)의 수명을 증가시키기 위해서 베어링(5)을 구성하는 회전체(5a)의 크기와 상기 회전체(5a)를 수납하는 수납홈(5b)의 크기를 증가시켜야 되는 데 종래의 전자클러치의 풀리는 로터부(1a)의 내부에 베어링(5)을 결합시키는 구조로 인해 회전체(5a)의 크기 및 수납홈(5b)을 증가시키는데 구조적인 한계로 인해 베어링의 내구성이 저하되는 문제점이 있다.That is, in order to increase the life of the bearing 5, the size of the rotating body 5a constituting the bearing 5 and the size of the receiving groove 5b for accommodating the rotating body 5a should be increased. The pulley of the electromagnetic clutch increases the size of the rotor 5a and the receiving groove 5b due to the structure in which the bearing 5 is coupled to the inside of the rotor portion 1a. There is this.

또한, 상기 로터부(1a)에 베어링(5)을 압입시킨 상태에서 베어링(5)의 이탈을 방지하도록 코킹(6) 작업을 수행함으로서, 작업성이 저하되는 문제점이 있다.In addition, there is a problem in that workability is deteriorated by performing the caulking 6 operation to prevent the bearing 5 from being detached in the state in which the bearing 5 is pressed into the rotor portion 1a.

또한, 풀리를 단조 작업등으로 제조하는 과정에서 로터부(1a), 풀리부(1b) 및 페이스(1c)를 일체로 드로잉 작업을 함으로서, 제조공정이 복잡하여 작업성이 저하되는 문제점이 있다.In addition, since the rotor unit 1a, the pulley unit 1b, and the face 1c are integrally drawn in the process of manufacturing the pulley in a forging operation, the manufacturing process is complicated and the workability is deteriorated.

상기한 문제점을 해결하기 위한 본 발명의 목적은 베어링의 외륜과 풀리의 로터부를 일체로 형성하여 베어링의 회전체 크기 및 수납홈을 증가시킬수 있도록 함으로서, 베어링의 내구성을 향상시키도록 하는 전자클러치의 풀리를 제공함에 있다.An object of the present invention for solving the above problems is to form the rotor portion of the outer ring and the pulley of the bearing integrally to increase the size of the rotating body and the receiving groove of the bearing, thereby improving the durability of the electronic clutch pulley In providing.
