Hello, everyone, today Uliflex and everyone says the choice which a few items to consider when coupling. 1. The size and nature of transmission torque required, whether can resonate, and presence of cushion and vibration reduction function. 2. For manufacturing and assembly errors, axial loading and thermal expansion deformation caused by the two axis relative displacement. 3. The appearance of the selected size and installation method of space for the operation of the assembly, adjustment and maintenance required. In addition to the above, still need to consider the work environment, service life and lubrication, sealing and economic conditions, as well as the reference for all kinds of coupling features, choosing the appropriate coupling.
