Rigid couplingThe products are divided into the following categories:
Rigid fixed sleeve coupling: simple structure, easy to manufacture, small radial size, low cost, but it needs to move a large distance in the axial direction during assembly and disassembly, and can only be used to connect two cylindrical shafts with the same diameter Shaft extension is suitable for low-power shafting systems that work smoothly and often rotate forward and backward.
Jacketed coupling: It is easy to assemble and disassemble, no need to move the two shafts in the axial direction, but the diameter of the two shafts must be the same cylindrical shape, and the shaft head should be processed with grooves for low-speed, non-impact load transmission.
Flange coupling: simple structure, low cost, but can not absorb shock, can not eliminate the adverse consequences caused by the two-axis alignment error, used to connect low-speed and low-rigidity two shafts under the condition of little vibration, manufacturing When the accuracy is high, it can be used for high-speed transmission.
Rigid removable gear coupling: It has high load-bearing capacity, reliable work, and good performance in compensating the relative displacement of the two shafts, but it is difficult to manufacture and requires good lubrication. It can be used for variable forward and reverse rotation, frequent start-ups, and various High-power horizontal transmission shaft system at speed. The TGL type is suitable for small and medium power. The GIICL and GIICLZ types have higher transmission torque capacity, but the relative displacement compensation performance is not as good as that of the GICL and CI CLZ types. Generally, the latter is more widely used. GI CLZ type needs to add an intermediate shaft, which can increase the radial and angular displacement.
