Abstract
본 발명은 종래 주물제품에서의 문제점을 감안하여 양질의 제품을 제공하려고 알루미늄 다이케스팅 클러치 모터커버에 관한 것이다.The present invention relates to an aluminum die casting clutch motor cover in order to provide a high quality product in view of the problems in conventional casting products.
일반적으로 알려져있는 범용모터커버는 이미 알려져있는 바와같이 주조형성한 것만으로 사용하고 있고, 특수모터에 한해서만 알루미늄 다이케스팅 한 커버가 사용되고 있는데, 그 이유는 알루미늄 다이케스팅 커버를 사용하는데 있어서 재질상의 특수성으로 인한 난성을 가지고 있기 때문이다.The general-purpose motor cover is generally known, and is used only by casting molding, and only aluminum die-casting cover is used for special motors. The reason is the difficulty of using aluminum die-casting cover. Because it has.
즉, 주물은 열팽상수축현상이 미세하나, 알루미늄은 그 정도가 심하기 때문에 베어링 등의 구동체가 작동하는 부분의 사용이 사실상 불가능하였기 때문이다.In other words, the casting has a fine thermal contraction phenomenon, but the aluminum is so severe that it is practically impossible to use the part in which the drive body such as a bearing works.
그래서 본발명에서는 상기 난성을 극복하기 위해서 열팽창수축이 활발한 구동체 하우징부 내부에 열팽창수축에도 변형이 거의 없는 이질체 붓싱을 알루미늄 다이케스팅 과정에 매입 구성하는 것으로서, 회동 및 습동작용 중에 발생되는 열팽창수축현상이 해소되게 한것이다.Therefore, in the present invention, in order to overcome the difficulty, the heterogeneous bushing, which hardly deforms even in thermal expansion contraction, is embedded in the aluminum die casting process, and thermal expansion contraction phenomenon occurs during rotation and sliding action. This is solved.
