Gear reducer troubles: causes and
corrective actions
19
Recycling
(keeping in mind the instructions in force):
– the elements of casing, gear pairs, shafts and bearings
of gear reducer must be transformed into steel scraps.
The elements in grey cast iron will be subjected to the
same treatment if there is no particular instruction;
– the worm wheels are made in bronze and must be treated adequately;
– exhausted oils must be recycled and treated according to the
instructions.
The paragraphs marked with present symbol contain
dispositions to be strictly respected in order to assure
personal
safety
and to avoid any
heavy damages
to the
machine or to the system (e.g.: works on live parts, on lif-
ting machines, etc.); the responsible for the installation or mainte-
nance must scrupulously
follow all instructions contained in
present handbook.
1 - General safety instructions
Gear reducers and gearmotors present dangerous parts because
they may be:
– live;
– at temperature higher than +50 °C;
– rotating during the operation;
– eventually noisy (sound levels > 85 dB(A)).
An incorrect installation, an improper use, the removing or disconnec-
tion of protection devices, the lack of inspections and maintenance,
improper connections may cause severe personal injury or property
damage. Therefore the component must be moved, installed, commis-
sioned, handled, controlled, serviced and repaired
exclusively by
responsible qualified personnel
(definition to IEC 364).
It is recommended to pay attention to all instructions of present
handbook, all instructions relevant to the system, all existing safety
laws and standards concerning correct installation.
Attention!
Components in non-standard design or with constructive
variations may differ in the details from the ones described here fol-
lowing and may require additional information.
Attention!
For the installation, use and maintenance of the electric
motor (standard, brake or non-standard motor) and/or the electric sup-
ply device (frequency converter, soft-start, etc.) and accessories, if any
(flow indicators, independent cooling unit, thermostat, ecc) consult the
attached specific documentation. If necessary, require it.
Attention!
For any clarification and/or additional information consult
ROSSI MOTORIDUTTORI and specify all name plate data.
Gear reducers and gearmotors of present handbook are normally
suitable for installations in industrial areas:
additional protection
measures,
if necessary for different employs, must be adopted and
assured by the person responsible for the installation.
IMPORTANT: the components supplied by ROSSI MOTORIDUTTORI
must be incorporated into machinery and
should not be commis-
sioned before the machinery in which the components have
been incorporated conforms to:
–
Machinery directive 2006/42/EC and subsequent updatings;
in particular, possible safety guards for shaft ends not being
used and for eventually accessible fan cover passages (or
other) are the Buyer’s responsibility;
–
«Electromagnetic compatibility (EMC)» directive 2004/108/
EC and subsequent updatings.
When operating on gear reducer (gearmotor) or on components
connected to it
the machine must be at rest:
disconnect motor
(including auxiliary equipments) from power supply, gear reducer
from load, be sure that safety systems are on against any accidental
starting and, if necessary, pre-arrange mechanical locking devices (to
be removed before commissioning).
If deviations from normal operation occur (temperature increase,
unusual noise, etc.) immediately switch off the machine.
The products relevant to this handbook correspond to the technical
level reached at the moment the handbook is printed. ROSSI MO-
TORIDUTTORI reserves the right to introduce, without notice, the
necessary changes for the increase of product performances.
2 - Operating conditions
Gear reducers are designed for industrial applications according to
name plate data, at ambient temperature 0
+40 °C (with peaks at
-10 °C and +50 °C), maximum altitude 1 000 m.
Not allowed running conditions: application in aggressive environ-
ments having explosion danger, etc. Ambient conditions must com-
ply with specifications stated on name plate.
3 - How supplied
3.1 - Receipt
At receipt verify that the unit corresponds to the one ordered and has
not been damaged during the transport, in case of damages, report
them immediately to the courier.
Avoid commissioning gear reducers and gearmotors, that are even if
slightly damaged.
3.2 - Name plate
Every gear reducer presents a name plate in anodised aluminium
containing main technical information relevant to operating and con-
structive specifications and defining, according to contractual agree-
ments, the application limits (see fig. 1); 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.
3.3 - Painting
Products are painted according to the painting table shown on page 18.
3.4 - Protections and packing
Overhanging free shaft ends and hollow shafts are treated with protec-
tive anti-rust long life oil and protected with a plastic (polyethylene) cap
(only up to D
48 mm for overhanging shafts, D
110 mm for hollow
shafts). All internal parts are protected with protective anti-rust oil.
