5.3

Aligning the coupling

5.3.1

Purpose of alignment

The shafts that are joined by the coupling are never on an ideal precise axis but have a certain

amount of misalignment.
Misalignment in the coupling leads to restoring forces that can stress adjacent machine parts

(e.g. the bearings) to an unacceptable extent.
The misalignment values in operation result from the following:
● Misalignment due to assembly

Incorrect position due to a lack of precision when aligning

● Misalignment due to operation

Example: Load-related deformation, thermal expansion

You can minimise misalignment by aligning after assembly. A lower misalignment in the

coupling has the following advantages:
● Reduced wear of the elastomer components
● Reduced restoring forces
● Misalignment reserves for operation of the coupling
You can find the maximum permitted shaft misalignment values during operation in section

Shaft misalignment values during operation (Page 62).
