Regarding connecting Coupling
There are some applications that you may need to use a coupling to connect encoder to the motor shaft, there’re a few tips to select a coupling type
1 you need to consider the magnitude and nature of the required transmitted torque, the requirements for buffering and damping functions, and whether resonance may occur.
2 you also need to think about the degree of relative displacement of the two axis axes caused by manufacturing and assembly errors, shaft loading and thermal expansion deformation, and relative motion between components.
3 regarding the applicable dimensions and installation methods, in order to facilitate the assembly, adjustment and maintenance of the necessary operating space. For large couplings, it should be possible to disassemble the shaft without axial movement.
4. In addition, consideration should be given to the working environment, service life, and lubrication, sealing, and economic conditions. Refer to the various coupling characteristics and choose a suitable coupling type.
5. Here are some coupling part number, please carefully check before ordering.
