Abstract
본 발명은 비원형 횡단면을 가진 피스톤 로드(8)의 안내부(16)가 축방향으로 통과되는 전면측에 배치된 피스톤 로드-안내장치(13)를 구비하며 하우징 측에 지지되어 안내부(16)의 외면(15)과 연동하고 피스톤 로드(8)의 횡방향 지지 및 회전 방지의 작용을 하는 롤러 베어링 장치(14)가 피스톤 로드-안내장치(13)에 사용되는 유체작용식 작동 실린더를 개시하고 있다. 피스톤 로드(8)의 안내부(16)의 외면(15)은 축방향으로 연장된 평평한 평면부(17) 및 둘레 방향으로 평면부(17)에 연이어 원통형으로 형성된 원통부(18)로 구성되며 롤러 베어링 장치(14)는 안내부(16)를 동축상으로 둘러싸고 원통부를(18)하고만 연동하는 볼 부시(37) 및 축방향으로 볼 부시(37)에 후속배치되고 축방향으로 피스톤 로드(18) 옆에나란히 회전 가능하게 설치되어 평면부(17)상에서 활주하는 베어링을 롤(22)을 구비한다.The present invention has a piston rod-guiding device (13) disposed on the front side where a guide portion (16) of a piston rod (8) having a non-circular cross section is passed in the axial direction, And a roller bearing device (14) that interlocks with the outer surface (15) of the piston rod (8) and acts to prevent lateral support and rotation of the piston rod (8) . The outer surface 15 of the guide portion 16 of the piston rod 8 is constituted by a flat flat surface portion 17 extending in the axial direction and a cylindrical portion 18 formed in a cylindrical shape in succession to the flat surface portion 17 in the circumferential direction The roller bearing device 14 includes a ball bushing 37 coaxially surrounding the guide portion 16 and cooperating only with the cylindrical portion 18 and a ball bushing 37 disposed subsequently to the ball bushing 37 axially, 18 on the flat surface portion 17 so as to be rotatable.
Description
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is a trivial issue, I did not include the contents of the text.
제1도는 본 발명에 따른 적합한 구성 형태의 피스톤 로드-안내장치를 구비한 유체작용식 작동 실린더의 전면측 단부 부분의 제2도의 절취선 I-I을 따른 종단면도, 제2도는 폐쇄 덮개를 가시적으로 나타내기 위해 베어링 롤 영역에서 절취하여 도시한 작동 실린더의 제1도의 Ⅱ-Ⅱ를 따른 횡단면도.FIG. 1 is a longitudinal section along a tear line II in a second view of a front side end portion of a fluid-operated working cylinder with a piston rod-guiding device of a suitable configuration according to the invention, FIG. 2 shows a closed- 2 is a cross-sectional view taken along line II-II of the first drawing of the operating cylinder cut out in the weighing bearing roll region.
