切槽电缆A SPOOLING律政司美国专利方法本发明涉及在有线假脱机装置的改进,更具体地说,但不是通过限制的方式,以围绕的外周提供连续组合平行且螺旋周向沟的方法电缆线筒体。
在电缆或线到滚筒芯的多个层的络筒,它以控制初始层的缠绕,以提供一个真正的,甚至在为了在电缆的外风或层任何维持任何其控制绕组是重要。许多系统已经引入以改进初始层的缠绕在鼓形铁芯,特别是在需要将电缆的许多层的鼓上要叠加电缆假脱机操作。例如,鼓型磁芯通常设置有连续的螺旋形或用于接收电缆的起始层的鼓凸缘之间延伸的螺旋状的槽。这种类型的开槽的有许多缺点,然而,在第二层,和随后将电缆的各层必须在涡卷之间从第一风的相反纵向方向的滚筒,和电缆的相当大的擦伤和不规则间距绕到该层的频繁发生。
提供一个真实,缠绕在滚筒芯电缆的多层次的平衡电缆后台打印系统已被富兰克林L。勒公交车,发展成为各种乐巴士先有技术专利,如美国专利证书披露号2620996 12月9日,1952年的发行的题为电缆卷绕装置;号2708080,1955年5月10日,题为葫芦ING鼓发出的; 号2732150,1956年1月24日,题为平衡电缆绕线; 和2734695号,颁布1956年2月14日,题为平衡电缆假脱机。由上述专利开发了假脱机系统已基本上消除现有开槽系统的缺点。因此,平衡后台极大地推进了电缆后台的艺术,并在提升各类产业会见了广泛的认可。论文网
LE总线平衡后台处理系统采用了鼓芯开槽设计,包括具有替代螺旋部分,直接或平行部分实现电缆缠绕操作的最佳控制的连续周向沟槽。在鼓芯该组合螺旋和平行开槽现在通常实现的几种方法之一。在一些情况下,多个槽条的个体弧形段的焊接在鼓芯提供为此所需开槽图案的外周。当然,在已经提供在其上的连续的螺旋或螺旋状的槽的滚筒芯必须首先以除去该槽加工,或通过平滑套筒覆盖,然后将槽杆可焊接到平原或光滑的表面。此开槽方法具有一些鼓许多缺点是用高碳钢,并且可以不进行焊接。此外,个别槽棒在滚筒芯的外周的焊接需要大量时间,尤其是在诸如用于采矿大鼓,和类似物。甚至更多的时间必须花费,当然,当有必要机油旧凹槽或之前加一个普通的套筒weldingof在滚筒芯的槽杆。此外,需要轧制根据各种有线或线直径的槽条昂贵的模具。
