NOTICE!
Gear unit damage
Forces which are caused by incorrect installation may cause premature damage to the gear unit.
• The gear unit and the base must be precisely aligned with the drive shaft of the machine in order to prevent
additional forces from being imposed on the gear unit due to distortion.
The base on which the gear unit is fitted must be vibration-free, torsionally rigid and flat.
The flatness of the bolting surface on the base must be of the appropriate precision (See
7.5 "Tolerances for bolting surfaces"
).
Any contamination to the bolting surfaces of gear unit and base must be thoroughly removed.
The base must be designed according to the weight and torque, taking into account the forces acting
on the gear unit. Bases which are insufficiently rigid may lead to radial and axial displacement during
operation, which is not measurable when the unit is stopped.
When attaching the gear unit to a concrete base using masonry bolts or base blocks, appropriate
recesses must be provided in the base. Tensioning bars must be cast into the concrete base in their
aligned state.
Bolts with a minimum quality of 8.8 must be used to fasten the gear unit. The bolts must be tightened
to the correct torques (See Section 7.4 "Torque values").
Information
Orientation
The service life of shafts, bearings and couplings depends on the precision of alignment of the shaft. Therefore,
zero deviation
should always be aimed for in alignment. For this, e.g. the requirements for the coupling should
be obtained from the special Operating Manuals.
The tolerances of the shaft ends and the flange connections should be obtained from the specific
dimension sheet for the order.
NOTICE!
Gear unit damage
Bearing damage and damage to the gear teeth due to passage of electric current.
• The gear housing must always be earthed.
• For geared motors, earthing via the motor connection must be ensured.
• Welding on the gear unit is prohibited.
• The gear unit must not be used as the earth connection for welding work, as this may cause damage to the
bearings and gears.
