Selection of couplings Sep 04, 2018

(1) The magnitude and nature of the torque to be transmitted, the requirements for the buffer and damping functions, and the possibility of resonance.

(2) Relative displacement of two axes caused by manufacturing and assembly errors, axial load and thermal expansion deformation, and relative motion between components.

(3) Permissible dimensions and installation methods, in order to facilitate assembly, adjustment and maintenance of the necessary operating space. For large coupling, it should be able to assemble and disassemble the shaft without axial movement.
