종래의 회전자 조립체는 로터 종단의 기어 성형시 높은 정밀도를 위하여 사출 압력이 높아지고, 사출 싸이클이 길어짐에 따라 사출물의 외부에 인서트 성형되는 마그네트에 클랙이 발생하는 문제점이 있었다.Conventional rotor assembly has a problem that the injection pressure is increased for high precision during the molding of the gear of the rotor end, the crack is generated in the magnet that is insert-molded outside the injection molding as the injection cycle is longer.
본 고안은 상술한 종래의 문제점을 극복하기 위한 것으로, 본 고안의 목적은 사출시 문제로 되는 로터 종단부의 분리 사출로 마그네트 인서트 부분에 불필요한 가압 현상을 줄이고, 사출 싸이클을 단축시켜 생산성을 향상시키는 회전자 조립체를 제공하는데 있다. The present invention is to overcome the above-mentioned conventional problems, the object of the present invention is to separate the injection of the rotor end that is a problem during injection to reduce the unnecessary pressure phenomenon on the magnet insert portion, to reduce the injection cycle to improve the productivity An electronic assembly is provided.
본 고안에 따른 회전자 조립체의 일예로서, As an example of the rotor assembly according to the present invention,
상부 및 하부의 내측에는 폭이 작아지는 단층부가 형성된 마그네트와, A magnet having a single-layer portion having a smaller width inside the upper and lower portions,
상부 및 하부에서 직경이 확대되는 확장부가 형성되어 상기 단층부에 각각 안착되며, 상부의 확장부에는 구멍이 다수개 형성되고, 내측에 홈이 형성된 마그네트 사출 성형부, 및Magnets are formed in the upper and lower parts are expanded to the diameter is respectively seated on the monolayer, the upper portion is formed with a plurality of holes, the groove is formed in the magnet injection molding, and
피니언부의 하부측으로 다수개의 연장부가 연장되고, 상기 연장부에는 각각 걸림턱이 구비된 피니언 성형부A plurality of extension parts extend to the lower side of the pinion part, each of which is formed with a locking jaw pinion molded part
로 구성되어, 마그네트를 넣고 마그네트 사출 성형부를 사출 성형한 다음, 피니언 성형부를 마그네트 사출 성형부에 끼워 넣어 조립이 완성된다.The magnet is inserted into the magnet injection molded part, and then the pinion molded part is inserted into the magnet injection molded part to complete the assembly.
이하, 본 고안의 실시예를 도 1 및 도 2를 참조하여 설명하기로 한다. Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 and 2.
