For Gear Unit
selection Prime mover's maximum power rating can be taken
as base for determining the actual load. The Gear
Selection is made by comparing actual transmitted loads
with catalogue ratings. It is important to realise that
are based on standard set of load conditions,
which invariably change for different conditions.
Therefore service factor must be used to calculate a
theoratical transmitted load or equivalent load, before
comparing with catalogue rating. For calculating the same,
apply the formula:-
Equivalent Load =
Actual Load x Service Factor

The
models relate to Centre Distances in
millimeter.
The
Ratios mentioned above are nominal and
the actual may vary by upto +10%
The
Model no. 50 to 85 are available in
adaptable Bodies, while 100 to 350 are in
Horizontal & Vertical Output Shafts
Bodies
For
overdriven Units, it is necessary to
derate by 5% for all the ratios up to 30:1
inclusive and by 15% for 35:1 and higher
ratios.
Worm
Shafts and Worm Gears are also available
without bodies.
