Fastening bolts or nuts must be tightened to the
correct torque.
If external forces are acting upon the gear unit, it is
advisable to prevent the unit from displacement by
means of lateral stops.
For dimensions, space requirement, arrangement
of supply connections (e.g. with separate oil-
cooling units), refer to the drawings in the gear-unit
documentation.
4.2 FOUNDATION GENERAL
The foundation frame must be horizontal and plain.
The gear unit must not be excessively stressed when
tensioning the fastening bolts.
The levelness of the gear-unit standing surface is
especially important, as the contact pattern of the
teeth and the load of the bearings depend on it and
the service life of the gear unit is affected by it. All
points on the gear-unit standing surface must lie
between two imaginary parallel planes 0.1 mm per
1 m apart.
Clean the undersurface of the gear-unit base and the
foundation frame.
Using suitable lifting gear, place the gear unit on the
foundation frame.
Use only the eyes provided to attach lifting equipment
to the unit. Do not use the front threads at the shaft
ends to attach slinging and lifting gear for transport.
Tighten the foundation bolts to the specified torque if
necessary, use stops to prevent displacement.
Align the gear unit exactly with the input and output
units.
Record alignment dimensions.
4.2.1 Foundation —
The gear unit must be mounted on
leveled foundation using the correct size and type
of foundation bolts. The foundation must have
sufficient load carrying capacity. The foundation
must be cast in the proportion like M150/M200,
with suitable reinforcement. A civil engineer,
expert in foundation technology should be
consulted for checking suitability of foundation.
The gear unit can be mounted in an inclined
position, refer Fig. 2, only if this requirement is
specified while ordering out the gear unit.
Where the gear units are used in outdoor
installations, they should be protected from direct
sun, wind and rain. During operation, the free
airflow along with the surface of unit should not
be obstructed.
Where the lower parts of the gear casing are
provided with an integrally cast and machined
levelling seat, while aligning the gear unit with
the prime mover and driven equipment, check
the horizontal level by means of levelling seats.
Correct leveling ensures proper lubrication of
bearings.
4.3 INSTALLATION
Quiet running and long service life of the gear unit
largely depend upon correct installation. Permissible
deviation from the dimension “a” can be checked from
the data provided by the coupling manufacturer (Fig.
3).
Installation should be carried out in such a way
that inspection cover and drain plugs are readily
accessible. Clients are requested to make provision for
suitable draining pan below the oil outlet.
