Disassemble the coupling, such as the work before the Flange Coupling is disassembled:
When removing the coupling, the coupling bolts are generally removed first. Due to the deposition of a layer of grease, corrosion products and other deposits on the surface of the thread, the bolts are not easily disassembled, especially for bolts with severe corrosion. The removal of the coupling bolts must be made with the right tool, because the stress surface of the outer hexagon or the inner hexagon of the bolt has been slipped and damaged, which is more difficult to disassemble. For bolts that have been rusted or have a lot of grease, the joint between the bolt and the nut is often sprayed with a solvent (such as a loose rust agent) to allow the solvent to penetrate into the thread, which is easy to disassemble.
Disassemble the coupling, such as Drum Gear Coupling removal process precautions:
Disassembly and assembly are the opposite process, and the purpose of the two is different. The assembly process is to assemble the coupling according to the assembly requirements, so that the coupling can transmit torque safely and reliably. Disassembly is usually due to equipment failure or the coupling itself needs to be repaired, the coupling is disassembled into parts. The degree of disassembly is generally determined according to the maintenance requirements. Some only require the two shafts of the coupling to be disengaged. Some not only disassemble the coupling but also remove the hub from the shaft. There are many types of couplings, the structure is different, and the disassembly process of the coupling is different.
