Coupling of disassembly and assembly

Disassembled and assembled the reverse process, the purpose of both is different. Assembly process is assembling a coupling according to the requirements of assembly, can make the coupling torque is safely and reliably. Disassembly is generally due to equipment failure or coupling itself need maintenance, taking down the coupling into parts. Remove the degree of general according to maintenance requirements, there are only asked to join the two axis release, there is not only to the coupling all its decomposition, but also take down on the wheel from the shaft. A lot of more phyletic, the structure of the coupling each are not identical, coupling the disassembly process is different also, in this initiation mainly introduces coupling some problems need to be aware of. Due to the coupling gear connected to the shaft vibration is tight, Interference fit) And flange in less space, it is difficult to remove the gear coupling. To this end, we design a kind of special removal tool, simple and convenient and practical. Coupling itself fault and the need to remove, to do careful examination for coupling as a whole ( Have been especially for damage coupling) , should find out the fault reason. Prior to the demolition in the coupling to the location of the coupling between various components cooperate with each other for some tokens, for reference when loading. For high speed machine coupling, the connecting bolt after weighing, marking must be clear, can't make a mistake. Removing coupling general down the connecting bolt first. Deposits a layer of oil dirties, because thread surface corrosion products and other sediments, bolt is not easy to remove, especially for corrosion serious bolt, disassembly is very difficult. The removal of the connecting bolt must choose the right tools, because the outside hexagon bolt, or within the slippage of the hexagonal bearing surface has damage, remove the will be more difficult. For corrosion of the bolts or more oil dirties, often with solvent ( Such as loose rust agent) Spraying the connection place of bolt and nut, let solvent into the thread, so that it will be easy to remove. In the process of coupling disassembly, the most difficult work remove the wheel from the shaft. For the linkage of the wheel hub, generally in three feet Lamar or four feet Lamar disassembly. Choose Lamar should be suitable and the appearance of wheel size, Lamar's feet square peg and on the surface of the wheel back to the right, won't produce slippage during hard to imagine. This method of interference fit smaller hub is only used to remove, the interference to the larger wheels, often by heating method, or cooperate with hydraulic jack to remove at the same time. Coupling all the parts for washing, cleaning and quality evaluation is the coupling after removal of a very important job. Parts of the assessment is to point to each parts after the operation, its size, shape, and material properties of the existing status and parts design and quality standards, to determine which parts can continue to use, which some parts should be used after repair, which belongs to spare parts should be scrapped.
