5. INSTALLATION

5.1. FITTING OF ACCESSORIES
The metric shaft extensions are equipped with keyways according to DIN
6885 "Blatt 1 - Form N1 or N3".
Threaded centre holes in these shafts according to DIN 332 Teil 2 Form D.
Couplings should be mounted on the shafts with interference fit according to
specifications. In case of doubt please refer to HANSEN.
Remove protection from shaft extensions and check keyfit and keyway height
in component to be mounted onto shaft. Heating the component to 80-100°C
(175-210°F) will be helpful. Threaded centre hole in shaft to assist in moun-
ting components onto shaft may be used.
Never mount components by impact as this may
cause damage to the bearings.
Never use rigid couplings except on free end machine shafts (e.g. mixers,
aerators) or in executions with a torque arm.
5.2. EXTERNAL LOADS
If external loads act on the gear unit, thrust blocks must be installed against
the unit's feet, to prevent gear unit from shifting. Components transmitting
radial load to the shaft should be mounted as close as possible to the hous-
ing.
Avoid exaggerated tension in transmission belts mounted on input or output
shafts. On gear units with built-on motor and V-belt drive, tension has been
factory set. Tension should be rechecked after 24 hours service. Chain trans-
missions must be mounted without preliminary tension.
In case a pinion is mounted on the shaft extension of the gear unit, care
should be taken to have normal required backlash between pinion and gear
and good contact pattern must be assured.
5.3. ERECTION
5.3.1. Levelling
Always mount gear unit in position for which it
was ordered.
Before altering this position or inverting the unit, please consult HANSEN.
It may be necessary to readapt the lubrication system.
5.3.2. Alignment
Align gear unit as accurately as possible with driving and driven machinery.
Install gear unit level to better than 5 mm per 1 m (5/32 inch per 3 feet or
5mrad or 17 arc minutes) or within the limits indicated on the outline
drawing for positions other than horizontal.
Maximum allowable misalignment depends on the couplings fitted on the
shaft extension, please refer to data provided with coupling.
Use three fixation points of gear unit for alignment. Adjust other fixation
points by shimming to 0,1 to 0,2 mm (0.004 to 0.008 inch), depending on
the size of the gear unit.
5.4. SECURING OF SOLID SHAFT GEAR UNIT
Gear unit must be mounted onto a rigid and stable bedplate or foundation in
order to avoid vibrations and possible overload of the housing fixation pads.
Use fixation holes indicated on dimensional drawing.
After correct alignment and shimming of all points, fix gear unit solidly onto
its foundation with appropriate size bolts, grade 8.8 according to DIN 267
or SAE grade 5 for bolts 1 1/2" and smaller, ASTM.A-354 grade BC for
bolts larger than 1 1/2", and grade 80 according to DIN 267 for stainless
steel bolts. Dimensions and tightening torques: see table.
Note: for some horizontal executions with parallel shaft and fans, the
protection hood of the fan must be removed (and remounted afterwards) to
enable tightening of the bolts.

The alignment of the complete drive packages mounted on a bedplate have
been carefully checked before shipment. It is nevertheless required to check
that the bedplate has not been deformed during transport or installation.
Therefore check again alignment of couplings or other elements after final
installation.
