Coupling application examples!

For the low-speed shaft with stable load, if the two axes are aligned accurately and the shaft's own stiffness is good, a rigid coupling can be selected.

If the alignment is difficult and the rigidity of the shaft is poor, a coupling with compensating offset can be selected.

If the two axes into a certain Angle, you can choose a universal coupling.

For relative displacement and harsh working environment, roller chain coupling can be selected.

For the heavy duty transmission with high power and no impact, it is recommended that the gear coupling be preferred.

For heavy load transmission with severe impact load at the same time, it is suggested that rubber metal ring coupling, tire coupling or spring coupling with high elasticity should be preferred.

For high-speed transmission, couplings with high balance accuracy should be selected, such as diaphragm couplings, gear couplings, etc., rather than sliding block couplings with bias.

For the general highway does not exceed tens of kilowatts and the impact is not small non-standard mechanical equipment, when the radial offset of the two axes is not greater than 0.15mm, the angular offset is not greater than 0.5°, it is recommended that the cheap elastic pin coupling be preferred, when the radial offset of the two axes is not greater than 0.15mm and the angular offset is not greater than 1°. It is suggested that the cheap plus-shaped elastic coupling should be preferred; Only when the radial deviation and angular deviation of the two axes are larger, the gear coupling and the tire coupling with better compensation function and higher price are considered. When the angular offset is not greater than 1.5°, the universal coupling should be considered.

If the coupling is required to work with high reliability, it is appropriate to choose a coupling made of metal components that do not require smooth, such as diaphragm elastic coupling, roller chain coupling, etc. The coupling that needs to be smooth, such as the gear coupling, the slider coupling, etc., may cause pollution to the environment, and should not be used in the occasion that requires the environment to be particularly clean. The coupling containing non-metallic components such as rubber is easy to age and deteriorate under the action of high temperature and corrosive media, so it is not suitable for use in this environment.
