Choice of coupling
There is no universal coupling -- any form of coupling has its own unique characteristics, but also its own incomplete tasks.
Choosing the right coupling requires understanding the context and purpose for which coupling is used:
Driver condition - driver name, drive power (kw), drive speed (RPM), drive end output form (shaft, flange, flywheel, etc.) and size.
Status of the driven device - name of the driven device, input form of the driven end (shaft, flange, flywheel, etc.) and size.
The situation between the two devices - whether there is a space requirement or limitation between the two devices, the position of the two devices (vertical or horizontal).
Environmental conditions - ambient temperature, chemical erosion, open or indoor use of couplings and other conditions requiring special attention
Other conditions that need special attention when choosing coupling:
Torsional transfer: whether additional safety factor is required;
Compensation deviation: whether deviation in a certain direction needs to be considered;
Transmission accuracy: whether synchronous transmission is required;
Is it necessary to mitigate torsional or equipment vibration in equipment operation?
Equipment protection: whether overload protection or failure/safety design is required;
t (n.m) =p (kw) *9550/rpm*k
t -- torsion, in Newton-meters.
P - Driving power, unit: kW
RPM - Drive speed, unit: RPM
k1= load coefficient k2= running time coefficient k3= start-stop frequency coefficient
