2.1.2.1
Advantages
• Increased critical speed due to less shaft bending.
2.1.2.2
Disadvantages
• Longer overall length of the test bench due to the use of double-element couplings.
• Increased price due to the higher price of double-element couplings.
Note :
Supported installations are required when larger misalignments
between the different elements of the system are a possibility, as
well as with high rotational speeds.
high-performance couplings can be realized by mounting flanges directly onto a splined torque
transducer shaft. (Not available on all models.)
