Abstract

본 발명은 비데오 테이프 레코더의 실린더에 있어서, 축받침을 위한 새로운 베어링에 대한 것으로 발명의 주된 목적은 볼 베어링의 기능과 동압 베어링의 기능을 복합적으로 보유하도록하여 보다 저렴한 가격이면서 제작이 용이한 제품을 공급할수 있도록 하는데 목적이 있다.The present invention relates to a new bearing for a shaft bearing in a cylinder of a video tape recorder, and the main object of the invention is to have a combination of the function of a ball bearing and the function of a dynamic pressure bearing, It is aimed to be able to supply.

이를 위한 주요 구성은 비데오 테이프 레코더의 실린더에서 축이 관통하되, 베어링을 개입시켜 회전이 가능하도록 이루어진 드럼에 있어서, 상기한 드럼의 허브부에서 외경이 상기한 축공과 접하는 다수의 구멍을 형성하고, 그 내부에 각각 하나씩의 롤러를 삽입하여 축공에 끼워진 회전축에 대해 구름접촉하도록 하는데 있다.The main structure for this purpose is a drum having a shaft through a cylinder of a video tape recorder, the drum being rotatable through a bearing, wherein a plurality of holes having an outer diameter in contact with the shaft are formed at a hub portion of the drum, And one roller is inserted into each of them to make a rolling contact with a rotation shaft inserted in the shaft hole.
