이와 같은 본 고안은 베어링홀더(4)의 구멍(401)에 끼워 고정한 합성수지제의 베어링(7)과 베어링홀더(4')의 구멍(401)에 끼워 고정한 합성수지제의 베어링(8)에는 윤활유홈(701)(802)과 윤활유공간부(801)를, 축(3)에는 윤활유홈(302)을 형성하여 그리스(GREASE)등의 기름을 유입하였기 때문에 장기사용에도 베어링(7)(8)과 축(3)의 접촉부는 윤활유에 의하여 마찰 및 회전저항이 감소케되어 매우 원활하게 회전된다.The present invention has a lubricating oil groove in a synthetic resin bearing 7 fixed to the hole 401 of the bearing holder 4 and a synthetic resin bearing 8 fixed to the hole 401 of the bearing holder 4 '. 701 and 802 and the lubricating oil space portion 801, the lubricating oil groove 302 is formed in the shaft 3, so that oil, such as grease, flowed into the bearings (7) and (8) The contact portion of the shaft 3 is rotated very smoothly by the friction and rotational resistance is reduced by the lubricant.

이에 따라 열발생 및 소음발생을 대폭 감소시킬 수 있음과 아울러 종래의 판스프링(13)과 커버(14)를 생략한 간단한 구조로 생산비를 절감할 수 있다.Accordingly, the generation of heat and noise can be greatly reduced, and the production cost can be reduced by a simple structure that omits the conventional leaf spring 13 and the cover 14.

그리고 윤활유홈(701)(802)은 한쪽이 외부로 개방된 상태이지만 그리스등의 윤활유는 끈끈한 점성이 높기 때문에 외부로 흘러내림이 방지된다.The lubricant grooves 701 and 802 are open to the outside, but lubricants such as grease have high sticky viscosity, thereby preventing them from flowing out.

이와 같은 본 고안은 소형모터의 베어링(7)(8)에는 윤활유홈(701)(802)과 윤활유공간부(801)를 형성하고 축(3)에는 윤활유홈(302)을 형성하였기 때문에 장기사용에도 종래의 오일리스베어링(12)에 비하여 열발생과 소음발생을 대폭 감소시킬 수 있음과 아울러 구조의 간단화로 생산비를 절감할 수 있는 효과가 있다.The present invention has a long-term use since the lubricant grooves 701 and 802 and the lubricant space portion 801 are formed in the bearings 7 and 8 of the small motor, and the lubricant grooves 302 are formed in the shaft 3. In addition, compared to the conventional oilless bearing 12, it is possible to significantly reduce heat generation and noise generation, and to reduce the production cost by simplifying the structure.
