Diagram Showing Pulling On And Pulling Off Drive Output Elements - Siemens SIMOTICS XP 1MB5 Operating Instructions Manual

Assembly
5.3 Lift the machine to where it will be mounted and position it
Shaft extensions with feather key
• If the output element is shorter than the feather key for balancing type "H": Cut off the section
of the feather key that protrudes from the shaft contour and output element. Alternatively,
ensure that the weights are compensated to achieve the appropriate balance quality.
• If the output element is pulled on up to the shaft shoulder: When balancing the coupling,
take into account that the feather key does not take up all of the coupling slot.
• The following applies for all two-pole machines and four-pole machines with a frequency
≥60 Hz:
– The feather key must be shortened if the coupling hub is shorter than the feather key.
– The center of gravity of the coupling half is within the length of the shaft extension.
– The coupling used is prepared for system balancing.
The number of poles of the machine is specified on the rating plate (in the designation of the
motor type).
