Requirements
The following requirements must be fulfilled before the assembly work commences:
• The foundation must be horizontal and level.
• When tightening the fastening bolts, make sure that the gear unit is free of mechanical
stress.
NOTICE
Poor stability
Damage to the gear unit is possible if it is not mounted on a stable foundation.
Make sure that the foundation frame is horizontal and level. It is particularly important that
the surface on which the gear unit is mounted is level because this determines the contact
pattern of the teeth and the load on the rolling-contact bearings, and so has an influence
on the service life of the gear unit. All points on the gear unit mounting surface must lie
between two imaginary parallel planes that are 0.1mm per 1m apart.
Design the foundation frame according to the relevant weight and torque, taking into ac-
count the forces acting on the gear unit. The feet of the gear unit must be properly suppor-
ted. Base frames or substructures that are too soft can result in radial or axial displace-
ment during operation. This displacement is not measurable when the drive is at a stand-
still.
NOTICE
Use of incorrect attachment points
Use of incorrect attachment points may result in damage to the gear unit.
To transport the gear unit, only attach slings to the lifting eyes provided for this purpose.
Do not use the threads in the end faces of the shaft ends for attaching lifting equipment to
transport the gear unit.
Lifting equipment must be adequately designed to accommodate the weight of the gear
unit.
Procedure
To install the gear unit on a foundation frame, proceed as follows:
1. Clean the underside of the gear unit feet.
2. Use suitable hoisting gear to set the gear unit down on the foundation frame.
3. Tighten the foundation bolts to the specified tightening torque (Page75). If necessary,
install stops to prevent displacement.
4. Align the gear unit precisely with the input and output equipment (Page53).
5. Record the alignment dimensions.
6. Keep the report in a safe place together with these operating instructions.
