    • PROBLEM TO BE SOLVED: To provide a mandrel which can accurately hold a large belt on the central line of an apparatus such as a lathe, and to enable such a belt to be manufactured at a low cost without a saccate member. SOLUTION: On both ends of a cylindrical core shaft 1, a pair of circular plates 3 and 5 are respectively arranged. A groove 6 is formed or preformed on the surface of the plate 3 or 5 in such a manner that the groove 6 may face two adjacent circular plates, and the mandrel is formed by arranging an O ring 7 in the groove 6. When a space between the plate 3 and the plate 5 is clamped by a bolt, the O ring 7 is deformed and partially projects from the peripheries of the plates 3 and 5. Therefore, if the clamping is uniform, a gap between the mandrel and a sheet 10 becomes sufficiently uniform when the cylindrical sheet 10 made of a metal is fitted on the mandrel. In addition, by fitting or forming a belt base material 12 around the sheet 10 via the belt 11, and forming a coating on the top, the belt having the coating can be obtained.

    • 要解决的问题:提供一种心轴,其可以将诸如车床的装置的中心线上的大带精确地保持在一起,并且能够以低成本制造这样的带,而不需要缓冲构件。 解决方案:在圆柱形芯轴1的两端分别布置有一对圆板3和5。 在板3或5的表面上形成或预成型槽6,槽6可以面向两个相邻的圆形板,并且心轴通过在槽6中布置O形环7而形成。当空间 在板3和板5之间被螺栓夹紧,O形环7变形并且从板3和5的周边部分地突出。因此,如果夹紧是均匀的,则心轴和片材10之间的间隙 当由金属制成的圆柱形片10安装在心轴上时变得足够均匀。 此外,通过经由带11将片材10配置或形成带状基材12,并且在顶部形成涂层,可以获得具有涂层的带。 版权所有(C)2010,JPO&INPIT
