Description

회전축 조립형 일체형 워터펌프{SHAFT ASSEMBLE INTEGRATED WATER PUMP}Rotary shaft assembly type water pump {SHAFT ASSEMBLE INTEGRATED WATER PUMP}

조립형 회전축의 조립을 원할하게 하기위해 회전축 하부에 여러개의 고정형 엠보싱을 두었으며, 프레스로 회전축 하부의 중심에 BUSHING 작업을 이용하여 풀리와 회전축의 동심도와 직각도를 유지하여야 한다.In order to facilitate the assembly of the rotating shaft, several fixed embossings are placed on the lower part of the rotating shaft, and the concentricity and the right angle of the pulley and the rotating shaft should be maintained by using a busing operation at the center of the lower rotating shaft with a press.

냉각수를 엔진으로 공급할 수 있도록 하는 자동차용 워터펌프는 펌프하우징(30)의 내부에 설치된 회전축(60)의 일측에 임펠러(40)가 설치된 형태를 갖는 것으로, 임펠러(40)가 회전하게 되면 펌프하우징(30) 쪽으로 진입하는 냉각수가 원심력에 의해 외측으로 빠져나가 엔진의 각 부분으로 순환하게 되는 것이다.The water pump for automobiles to supply the coolant to the engine has an impeller 40 installed on one side of the rotating shaft 60 installed inside the pump housing 30, and the pump housing rotates when the impeller 40 is rotated. Cooling water entering the 30 is discharged outward by centrifugal force and circulated to each part of the engine.

상기에서 회전축(60)에 설치되는 임펠러(40)는 회전축(60)의 타측에 설치된 풀리(10)가 엔진의 크랭크샤프트와 벨트로 연결되어 엔진의 회전수와 동일한 회전수로 회전하게 된다.In the impeller 40 installed on the rotating shaft 60, the pulley 10 installed on the other side of the rotating shaft 60 is connected to the crankshaft and the belt of the engine to rotate at the same rotational speed as the engine rotational speed.

그런데 종래의 워터펌프에 있어서는 임펠러(40)가 장착된 회전축(60)의 원할한 회전을 위하여 베어링(50)이 조립된 회전축(60) 일체를 일본에서 수입하여 사용하고 있었으며, 상기 수입품을 펌프하우징(30)에 장착하고, 브라캣(20)을 장착하고, 풀리(10)를 장착하고, 최종적으로 임펠러(40)가 장착되어 워터펌프가 구성되므로, 부품 종류도 많고, 각각의 부품을 조립하는 다양한 공정이 필요하므로 제조원가가 높아지는 원인이 되고 있었다.However, in the conventional water pump, the rotary shaft 60, in which the bearing 50 is assembled, is imported from Japan for smooth rotation of the rotary shaft 60 on which the impeller 40 is mounted, and the imported housing is pumped. 30, the Bracat 20 is mounted, the pulley 10 is mounted, and the impeller 40 is finally mounted so that the water pump is constructed, so that there are many kinds of parts, and to assemble each part Since various processes are required, manufacturing costs have increased.

본 발명의 목적은 임펠러의 내경 허용 공차가 1/100mm 공차 범위로 정밀한 치수와 조도를 요구하므로, 풀리(10), 브라캣(20), 펌프하우징(30), 베어링(50), 회전축(60)을 별도의 조립없이 프레스의 스템핑 방법으로 베어링(50)과 회전축(60)을 제외한 풀리(10), 브라켓(20), 펌프하우징(30) 부품의 일체화된 일체형풀리(100)를 제공하고, 별도의 회전축(600)을 조립함으로써 여러가지 부품의 조립 공정을 없앨 수 있으며, 여러가지 부품을 일체화함에 있어서 보다 쉽게 일체형 풀리 제품을 생산할 수 있도록 하며, 엔진 내부의 워터펌프 조립 공간의 최소화를 도모할 수 있도록 하는 자동차 냉각장치의 워터펌프 구조를 제공하는 데에 있는 것이다.It is an object of the present invention that the tolerance of the inner diameter of the impeller requires precise dimensions and roughness in the tolerance range of 1 / 100mm, so that the pulley 10, the bracat 20, the pump housing 30, the bearing 50, the rotating shaft 60 ) Without the assembly of the press provides the integrated pulley (100) of the pulley (10), bracket (20), pump housing (30) parts except the bearing 50 and the rotating shaft 60 by the stamping method of the press By assembling a separate rotary shaft 600, the assembly process of various parts can be eliminated, and integrating various parts, it is possible to produce an integrated pulley product more easily, and can minimize the space of the water pump assembly inside the engine. It is to provide a water pump structure of a vehicle cooling system.

회전축과 일체형 풀리의 조립을 원할하게 하기 위하여 회전축의 하부에 여러개의 엠보싱을 두어 일체형 풀리의 홀(Hole)에 고정시키고, 프레스로 회전축의 하부 중심에 BUSHING 작업을 하여 동심도와 직각도를 맞춘다.In order to facilitate the assembly of the rotating shaft and the integrated pulley, several embossings are placed on the lower part of the rotating shaft to fix them in the hole of the integrated pulley, and the BUSHING work is performed on the lower center of the rotating shaft with a press to match the concentricity and the right angle.

스템핑 작업의 주요기술인 딥드로잉을 통하여 회전축과 일체화된 일체형 풀리를 만들기 위해서는 프레스 공정이 많아지므로 별도의 회전축을 조립하게 함으로써 프레스 공정을 줄이고 별도의 회전축을 한번의 공정으로 조립함으로써 쉽게 일체형 워터펌프 구조를 생산할 수 있다.In order to make the integrated pulley integrated with the rotating shaft through deep drawing, which is the main technique of stamping work, the press process is increased, so it is possible to assemble the separate rotating shaft to reduce the press process and easily assemble the separate rotating shaft in one process. Can produce

별도의 회전축을 제작함에 있어서, 풀리에는 브라캣 대용부분에 여러개의 홀을 생성하고, 회전축에는 풀리의 홀과 일치되는 위치에 여러개의 엠보싱을 두어 쉽게 고정시킬 수 있도록 하고, 후공정으로 풀리의 하부에 프레스로 BUSHING 작업을 하여 풀리와 회전축을 완전하게 고정시킴으로써, 직각도와 동심도를 맞출 수 있다.In the manufacture of a separate rotation shaft, the pulley creates a number of holes in the bracat substitute portion, the rotation axis can be easily fixed by placing a number of embossing at the position corresponding to the hole of the pulley, and the lower part of the pulley by the post-process BUSHING work by press to completely fix the pulley and the rotating shaft to match the squareness and concentricity.

워터 펌프의 풀리와 브라캣이 일체화된 일체형 풀리(100)에 중심 회전축(600)을 조립하여 최종적인 일체형 워터펌프 풀리 구조를 형성함 The central rotation shaft 600 is assembled to the integrated pulley 100 in which the pulley and the bracat of the water pump are integrated to form a final integrated water pump pulley structure.
