For the selection of suitable couplings the following criteria should be applied:
-
Couplings should be dimensioned in accordance with the torque and speed
hat are expected.
-
When estimating the possible loads one should take care of acceleration
and deceleration moments as well as the passing through critical speeds of
rotation. Periodic peaks of torque could be considerably higher than the av-
erage calculated from nominal power and speed. If the coupling is overdi-
mensioned as well as the torque transducer this will bring safety against
mechanical overloading.
-
Couplings should be selected so that any additional force or moment is
within the ratings, or cannot act on the torque transducer.
-
Couplings can be self centering. Angular displacements, parallel and axial
shifts shall be cancelled.
-
Mounting surfaces for the connection of the coupling housing shall be clean
and free from grease.
-
