4.1 - General
Every gear reducer is provided with a name plate in anodised aluminium containing main technical information
relevant to operating and constructive specifications and defining, according to contractual agreements (see
fig. ,below), the application limits; the name plate must not be removed and must be kept integral and readable.
All name plate data must be specified on eventual spare part orders.
Attention!
For the mass stated on name plate remind that:
– it does not consider the lubricant mass;
– it is the maximum one for the gear reducer size, therefore the actual one can be lower as it depends from train
of gears and transmission ratio;
– for the gearmotors the mass is always the same of gearmotor without motor, therefore consider also the mass
of motor stated on relevant name plate in order to know the total mass.
In view of above mentioned points, if it is necessary to know the exact mass, consult Rossi.
Gear reducers and gearmotors are mechanical devices including one or more gear pairs (with internal or external
toothing) with several space positions (parallel, intersecting, orthogonal axis), with the aim to reduce motion and
to increase torque of a rotating driving machine (e.g. electric, hydraulic motor, etc.) to drive a great number of
machines (lifting, traverse movements, rotations, etc.).
They are made of a cast iron or stainless steel housing, including shafts equipped with toothed gear wheels
and supported by taper roller bearings; the gear pairs and bearings are grease or oil lubricated with different
lubrication solutions: bath, splash or ducts lubrication; gear reducers and gearmotors are equipped with at least
one input (high speed) shaft and one output (low speed) shaft; the lubricant is kept inside the hoousing through
elastomer-based sliding seals.
