Abstract

본 발명의 목적은, 길이가 짧으면서도 큰 조인크 꺽임각을 형용하며, 변형된 상태에서 그 형태의 안정성을 유지하는 등속도 유니버설 조인트를 밀봉하기 위한 주름식 부트를 제공하는 것이다. 주름식 부트(1)의 관절 영역에는 적어도 하나의 다이아프램 영역(4)가 제공되고, 다이아프램 영역(4)는 횡단면으로 보아 방사상 외향 만곡부(7)과 방사상 외향 만곡부(7)보다 더 큰 곡률 반경을 갖는 방사상 내향 만곡부(8)로 형성되며, 두 개의 만곡부는 대향방향으로 연장됨으로써 그 목적이 달성된다.It is an object of the present invention to provide a corrugated boot for sealing a constant velocity universal joint which is short in length but also employs a large joint angle and maintains its shape stability in a deformed state. The articular region of the corrugated boot 1 is provided with at least one diaphragm region 4, the diaphragm region 4 having a greater curvature than the radially outwardly curved portion 7 and the radially outwardly curved portion 7 in cross section. It is formed as a radially inwardly curved portion 8 having a radius, the two curved portions extending in opposite directions to achieve the object.

제1a도는 제1도에 따른 주름식 부트의 장착 상태를 도시한 도면,1a is a view showing the mounting state of the corrugated boot according to FIG.

제2도는 다이아프램의 초기 형태와 설치 상태로 특징지워지는 제2형태로의 전이를 나타내고, 그 초기 형태에 있어서 두 만곡부의 곡률 반경들 사이의 전이 영역 상의 접선은 조인트 축과 90°각도를 형성하는 것을 도시한 개략도,2 shows the transition to the second form, characterized by the initial form and installation state of the diaphragm, in which the tangent on the transition region between the curvature radii of the two bends forms an angle of 90 ° with the joint axis. A schematic showing what to do,

제3도는 외부 만곡부와 내부 만곡부 사이의 두 곡률 반경의 전이 영역 상의 접선 각도는 그 범위가 0°내지 90°사이인 경우의 다이아프램의 개략도,3 is a schematic diagram of the diaphragm when the tangential angle on the transition region of two radii of curvature between the outer and inner curvatures is in the range of 0 ° to 90 °,

제4도는 서로 축방향으로 다섯개의 다이아프램이 인접하여 배치된 주름식 부트를 도시한 도면.4 shows a corrugated boot with five diaphragms disposed adjacent to each other in the axial direction.
