概述 Overview

液压紧配螺栓又称轴系液压螺栓或中间扩张液压拉伸螺栓，主要利用材料的弹性变形来实现间隙配合向过盈配合的转变，从而实现轴系扭矩的传递，是一种用于法兰联轴节上的新型螺栓，由外表带有一定锥度的拉紧螺栓，内孔带有相应锥度的中间锥套及两只紧定螺母组成。拉紧螺栓两端有螺纹，中间锥套的外表是圆柱形的，且与螺栓孔有一定的间隙。它的最大优点是装拆方便、重复使用以及省时省力，逐步代替传统的冷冻式螺栓。
Hydraulic bolt, also known as the axis of the hydraulic bolt or intermediate expansion of the hydraulic tension bolt, the main use of elastic deformation of the material to achieve clearance fit to the interference fit in order to achieve shaft torque transmission. It is a new t
ype bolt on the flange coupling, the appearance of the taper with a certain degree of taut bolts, the hole with a corresponding tapered middle taper sleeve and two tight nut composition. Tighten the bolt at both ends of the thread, the middle of the outer sleeve is cylindrical, and the bolt hole with a certain gap. Its biggest advantage is the easy assembly and disassembly, reuse and save time and effort, and gradually replace the traditional frozen bolt.
液压螺栓可以用在船舶轴系的主机（或减速箱）输出轴和中间轴、中间轴和中间轴以及中间轴和螺旋桨轴等用法兰联接的联轴节中，也可以用在蒸汽轮机、轧钢机或其它承受高扭矩的连接件中。产品可提供DNV·GL、ABS、LR、NK、KR、RINA、CCS等各船级社的船检证书。
Hydraulic bolts can be used in flanged joints of the main shaft (or reduction gearbox) output shafts and countershafts, countershafts and countershafts as well as countershafts and propeller shafts, as well as in steam turbines, steel rolling machine or other high-torque connection. Products can be provided DNV · GL, ABS, LR, NK, KR, RINA, CCS and ship inspection certificate of other classification societies.
