Product Description

JP Hydraulic Tight Fit Bolt
JP Hydraulic Fitting Bolt

Overview Overview

Hydraulic tight fitting bolts are also called shafting hydraulic bolts or intermediate expansion hydraulic tension bolts. They mainly use the elastic deformation of materials to realize the transformation from clearance fit to interference fit, thereby realizing the transmission of shafting torque. They are used for flange coupling. The new bolt on the joint consists of a tension bolt with a certain taper on the outside, an intermediate taper sleeve with a corresponding taper in the inner hole and two tightening nuts. Both ends of the tension bolt are threaded, and the appearance of the middle taper sleeve is cylindrical, and there is a certain gap with the bolt hole. Its biggest advantage is easy assembly and disassembly, repeated use and save time and effort, and gradually replace the traditional frozen bolts.
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.
Hydraulic bolts can be used in the coupling of the main engine (or gearbox) output shaft and intermediate shaft, intermediate shaft and intermediate shaft and propeller shaft, etc., which are flanged, and can also be used in steam turbines, rolling mills or other high-torque connections. Products can provide DNV GL, ABS, LR, NK, KR, RINA, CCS and other classification society ship inspection certificate.
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.
