Mounting On A Foundation Frame - Siemens FLENDER H SH Series Assembly And Operating Instructions Manual

Gear units of sizes 13 to 22 have special alignment surfaces on the top of the housing for preliminary
alignment of the gear units. To facilitate alignment of gear units of these sizes, alignment threads are
provided in the housing base.

1 Alignment surfaces
The final fine alignment with the assemblies on the in­ and output side must be carried out accurately by
the shaft axes, using:
• rulers
• spirit level
• dial gauge
• feeler gauge, etc.
Only then should the gear unit be fastened and the alignment checked once again.
• Record alignment dimensions.
The report must be kept with these instructions.
The accuracy of shaft axis alignment is an important factor in determining the life span
of shafts, bearings and couplings. If possible, the deviation should be zero (exception:
ZAPEX couplings). For amongst others the special requirements for the couplings,
refer to the specific operating instructions.
Non­observance can cause shaft rupture, resulting in serious injury or danger of life.

6.3.2.2 Mounting on a foundation frame

• Clean the undersurface of the gear­unit base.
• Using suitable lifting gear, place the gear unit on the foundation frame.
• Tighten the foundation bolts to the specified torque (see item 6.22); if necessary, use stops to prevent
displacement.
The gear unit must not be excessively stressed when tensioning the fastening bolts.
• Align the gear unit exactly with the input and output units (see item 6.3.2.1).
• Record alignment dimensions.
The report must be kept with these instructions.
