　　Two commonly used measurement and adjustment methods in the process of repairing couplings can be divided into different measurement tools: 1) Using a knife-shaped ruler and a feeler gauge to measure the misalignment of the coupling and using a wedge-shaped clearance rail or a feeler gauge to measure the coupling The non-parallelism of the end face of the device, this method is suitable...

　　The structure of the JQ type jacket coupling: there is no elastic body in the middle, and it is generally hoisted. There is a hoisting ring in the middle to hang the shafts at both ends. The diameter of the shaft hole is the diameter.It is generally used for vertical installation, and the middle part is slotted with the shaft heads of the suspension ring to hold the two ends of the device to transmit the torque. ...

　　The gearbox and the generator are connected by a flexible shaft. During the operation of the fan, the coupling compensates for the two parallelism deviations and angle errors.In order to reduce the vibration of the transmission, the coupling needs to have vibration and damping, in order to avoid torsional vibration in the case of deviation...

　　Drum gear coupling is a new type of gear coupling developed on the basis of spur gear coupling, digesting and absorbing foreign advanced technology.It is composed of an outer gear sleeve with a drum-shaped tooth thickness and a matching inner gear ring that connects the two shafts. It is suitable for heavy...

　　The coupling is axially embedded in the two halves by a serpentine spring leaf for more than 36%.The serpentine spring sheet with trapezoidal section is made of high-quality spring steel, subjected to strict heat treatment, and specially processed. It has good mechanical properties, so that the service life of the coupling is much longer than that of non-metallic elastic...

　　1. Elastic coupling clamping screw fixation: Utilize the tightening force of the hexagon socket bolt to shrink the slit and clamp the shaft tightly.This method is convenient to fix and disassemble, and will not cause damage to the shaft, so it is a very common fixing method. ...

　　1. Flange couplings (1) Ordinary flange couplings are connected by bolts with reamed holes, and are centered by bolts of reamed holes (corresponding to reamed bolts), and rely on the shear resistance of bolts to transfer Torque. 2. The flange coupling (2) is connected by ordinary bolts...

　　1) The allowable range of eccentricity is large, which can be flexibly applied to various transmission systems. 2) Quick disassembly and assembly, with high assembly repeatability. 3) No lubrication, no noise and wear.There are no sliding, friction, and transmission parts, which can reduce energy loss. 4) Simple structure,...

　　The initially selected coupling size, that is, the shaft hole diameter d and the shaft hole length L, should meet the requirements of the main and driven end shaft diameters, otherwise the coupling specifications must be adjusted according to the shaft diameter d.It is a common phenomenon that the shaft diameters of the driving and driven ends are different. When the torque and speed are the same,...

　　The outer dimensions of the coupling, that is, the maximum radial and axial dimensions, must be within the installation space allowed by the machine and equipment.Should choose a coupling that is convenient for assembly and disassembly, no maintenance, long maintenance period or convenient maintenance, replacement of wearing parts without moving the two shafts, and easy centering adjustment...
