4 - Mounting positions and lubrication
Mounting positions
Lubrication
Unless otherwise stated, gearmotors are supplied in mounting position B3 which, being standard, is omitted from the designation.
Gear pairs and bearings are oil-bath or splash lubricated.
Gearmotors are supplied filled with synthetic oil (KLÜBER Klübersynth GH 6-220, MOBIL Glygoyle 30, SHELL Tivela S 220) providing
lubrication «for life» – assuming pollution-free surroundings. Ambient
temperature range 32 ÷ 104 °F (0 ÷ 40 °C) with peaks of -4 °F (-20 °C)
and +122 °F (+50 °C).
The mounting position ordered affect the quantity of lubricant which
the gear reducer is filled with before delivering as well as possible
bearings with independent lubrication.
Important: be sure that the gearmotor is installed as per mounting
position ordered and stated on the name plate. If the gearmotor is
installed in a different mounting position, verify, according to the
values stated in the table, that the oil quantity doesn't change; if so,
adjust it accordingly. Moreover, V5 and V6 vertical mounting positions
need the upper bearings to be lubricated with special grease.
Seal rings: duration depends on several factors such as dragging

5 - Service factor fs
Service factor fs takes into account the different running conditions
(nature of load, running time, frequency of starting, other considerations) to which the gearmotor can be subjected and which must be
referred to when performing calculations of gearmotor selection and
verification.
Two equivalent methods are here proposed to determine the minimum
service factor required by applications:
- mass acceleration method: considering the overloads deriving
from the system inertia and running conditions (starts per hour, hours
per day, expected life);
- AGMA service factor: according to AGMA standards (although the
gearmotors of the present catalog are not strictly AGMA rated)
Mass acceleration method
For an analitical determination of the required service factor (especially considering the running hours), proceed as stated below and/or
consult us
– Calculate the mass acceleration factor mJ:
mJ =
WKR2
WK02
AGMA Service factor
Service factor
Before a gearmotor is selected, an application class number, which
represents the normal relationship between gear unit rating and the
maximum potential transmitted power, shall be determined.
The application class number and related service factor include the
combined effects of varying duty cycles, reliability, expected performance, plus magnitude and frequency of peak load occurrences in
an empirically determined single factor.
The application class numbers are I, II, and III (see AGMA tables for
application classification). Their relationship to service factor is shown
below (although the gearmotors of the present catalog are not strictly
AGMA rated, nevertheless the following table can be used to select a
proper service factor as well):
Application

fs 1
Steady loads not exceeding the nominal
specified input power, 8-10 hours / day

1.4
Steady loads not exceeding the nominal
specified input power and 24 hours / day

Moderate overloads and 8-10 hours / day
running.
2
Moderate overloads and 24 hours / day

Heavy overloads and 8-10 hours / day running.

WKR2 [lb ft2] is the external moment of inertia (of mass; couplings, driven machine)
WKL2 reflected to the motor shaft:
n 2
WKR2 = WKL2 . 2
nN
( )
WK02 [lb ft2] is the moment of inertia (of mass) of motor (see ch. 2b);
n2 [rpm] is output speed of the gearmotor;
nN [rpm] is nominal speed of the motor (see ch. 2b). As a guideline consider:
nN = 1 750 rpm for 4 poles and nN = 1 150 rpm for 6 poles;
– Select the proper overload class according to the acceleration
mass factor mJ:
mJ 0.3
(uniform load)
load classification I
mJ 3
(moderate overloads)
load classification II
mJ 10
(heavy overloads)
load classification III
For mJ values larger than 10, in presence of high values of backlash for kinematic chain, a specific evalutation has to be carried out: consult us.
– From the diagram, according to the overload class, the running time
and the starting frequency z, read off the minimum service factor
required.
− Whenever a higher degree of reliability is required (particularly
difficult maintenance conditions, key importance of gearmotor to
production, personnel safety, etc.) multiply fs by 1.25 ÷ 1.4.

Running condition
Caution: in case of high reliability degree requirements (eg.: application involving risks for personnel safety) or in presence of high inertia
loads or high starts/stops frequency, consult us.
6 - Selection
Determining the gearmotor size
− Make available all necessary data: required output power P2 of
gearmotor, speed n2, running conditions (nature of load, running
time, frequency of starting z, other considerations) with reference to
ch. 5.
− Determine service factor fs on the basis of running conditions (ch. 5).
− Select the gearmotor size on the basis of n2, fs and of a power P1
greater than or equal to P2 (ch. 8).
If power P2 required is the result of a precise calculation, the gearmotor
should be selected on the basis of a power P1 equal to or greater than
P2 / η, where η = 0,96 ÷ 0,94 is gear reducer efficiency (ch. 10). When
for reasons of motor standardization, power P1 available in catalog is
much greater than the power P2 required, the gearmotor can be selected on the basis of a lower service factor
fs . P2 required
provided it is certain that this excess power
P1 available
(
)
available will never be required and frequency of starting z is low
enough not to affect service factor (ch. 5).
Calculations can also be made on the basis of torque instead of power; this method is even preferable for low n2 values.
Verifications
7 - Radial loads (overhung loads OHL)
Fr2 [lbf] on low speed shaft end
Radial loads generated on the shaft end by a drive connecting
gearmotor and machine must be less than or equal to those given in
ch. 8.
Normally, radial loads on low speed shaft ends are considerable: in
fact there is a tendency to connect the gear reducer to the machine by
means of a transmission with high transmission ratio (economizing on
the gear reducer) and with small diameters (economizing on the drive,
and for requirements dictated by overall dimensions).
Bearing life and wear (which also affects gears unfavorably) and
low speed shaft strength, clearly impose limits on permissible radial
load.
Permissible radial loads are given in the tables of ch. 8 and are
referred to gearmotor’s output speed n2 and torque T2, considering
overhung load acting on center line of low speed shaft end, in the
most unfavorable direction of rotation and angular position of load.
If the exact direction of rotation and angular position of load are
known, an increase of permissible radial load may be achieved. If
necessary, consult us for the verification of specific instance.
In case of radial load acting in position different from center line
of low speed shaft end, i.e. operating at a distance different from
0,5 · E, the permissible radial load must be recalculated according
to the following formula, verifying not to exceed the max value Fr2max
stated in the table:
− Verify possible radial load Fr2 referring to directions and values given
in ch. 7 and 8.
− For the motor, verify frequency of starting z when higher than that
normally permissible, referring to directions and values given in ch.
2b and 10; this will normally be required for brake motors only.
− When a load chart is available, and/or there are overloads – due to
starting on full load (especially with high inertias and low transmission ratios), braking, shocks, gear reducers in which the low speed
shaft becomes driving member due to driven machine inertia, or
other static or dynamic causes – verify that the maximum torque
peak (ch. 10) is always less than 2 · TN2 (TN2 = T2 · fs, see ch. 8); if it
is higher or cannot be evaluated in the above instances, install suitable safety devices so that 2 · TN2 will never be exceeded.
Considerations on selection
Motor power
Taking into account the efficiency of the gear reducer, and other drives
– if any – motor power is to be as near as possible to the power rating required by the driven machine: accurate calculation is therefore
recommended.
The power required by the machine can be calculated, seeing that it is
related directly to the power-requirement of the work to be carried out,
to friction (starting, sliding of rolling friction) and inertia (particularly
when mass and/or acceleration or deceleration are considerable). It
can also be determined experimentally on the basis of tests, comparisons with existing applications, or readings taken with amperometers
or wattmeters.
An oversized motor would involve: a greater starting current and consequently larger fuses and heavier cable; a higher running cost as
power factor (cos ) and efficiency would suffer; greater stress on the
drive, causing danger of mechanical failure, drive being normally proportionate to the power rating required by the machine, not to motor
power.
Only high values of ambient temperature, altitude, frequency of starting or other particular conditions require an increase in motor power.

An axial load of up 0,2 times the value in the tables of ch. 8 is permissible, simultaneously with the radial load.
In case of no radial loads an axial load (not misaligned) of up 0,5 times
the value in the tables of ch. 8, is permissible.
If exceeded and/or for misaligned axial loads, consult us.

for chain drive (lifting in general);
k = 1.5 for timing belt drive;
k = 2.5 for V-belt drive;
k = 1.1 for spur gear pair drive;
k = 3.55 for friction wheel drive.

10 - Structural and operational details
Efficiency Operation with brake motor
− gear reducer with 2 gear stages (2I) 0.98, with 3 gear pairs (3I)
0.96; for T2 << TN2, could considerably decrease; consult us. T2
values stated on ch. 8 already include efficiency; if motor is supplied by the Customer, the torques generated on low speed shaft
could be smaller or currents absorbed greater.
Starting time ta and revolutions of motor a1
Overloads
Braking time tb and revolutions of motor
Where a gear reducer is subjected to high static and dynamic overloads, the need arises for verifying that such overloads will always remain
lower than 2 · TN2 (see ch. 8 where TN2 = T2 · fs).
Overloads are normally generated when one has:
− starting on full load (especially for high inertias and low transmission
ratios), braking, shocks;
− gear reducers in which the low speed shaft becomes driving member due to driven machine inertia;
− applied power higher than that required; other static or dynamic
causes.
The following general observations on overloads are accompanied by
some formula for carrying out evaluations in certain typical instances.
Where no evaluation is possible, install safety devices which will keep
values within 2 · TN2.
Starting torque
When starting on full load (especially for high inertias and low transmission ratios) verify that 2 · TN2 is equal to or greater than starting
torque, by using the following formula:
冢
WK 2R
+ T2 required
WK2R + WK20
冣
start
T2 start = T
· T2 available – T2 required
TN
where:
Tstart
is the motor starting torque (see ch.2);
TN
is the motor nominal torque (see ch. 2b);
T2 available is output torque due to the motor's nominal power;
T2 required is torque absorbed by the machine through work and frictions;
WK20
is the moment of inertia (of mass) of the motor (see ch. 2b)
WK2R
is the external moment of inertia (of mass; coupling, driven machine) reflected to
the motor shaft (see ch. 2b)
NOTE: when seeking to verify that starting torque is sufficiently high for starting, take into
account starting friction, if any, in evaluating T2 required.

inertia combined with high speeds) with brake motor

Frequency of starting z
As a general rule, the maximum permissible frequency of starting z
for direct on-line start (maximum starting time 0.5 ÷ 1 s) is 63 starts/h
up to size 90, 32 starts/h for sizes 100 … 132.
Brake motors can withstand a starting frequency double that of normal motors as described above.
A greater frequency of starting z is often required for brake motors. In

11 - Installation and maintenance
General
IEC frame motor mounting or replacement
Be sure that the structure on which the gearmotor is fitted is flat, levelled and sufficiently dimensioned in order to assure fitting stability and
absence of vibration, keeping in mind all transmitted forces due to the
masses, to the torque, to the radial and axial loads.
Position the gearmotor so as to allow a free passage of air for cooling
both gear reducer and motor (especially at motor fan side).
Avoid: any obstruction to the air-flow; heat sources near the gearmotor that might affect the temperature of cooling-air and of gearmotor
for radiation; insufficient air recycle or any other factor hindering the
steady dissipation of heat.
Mount the gearmotor so as not to receive vibrations.
When external loads are present use pins or locking blocks, if necessary.
When fitting gearmotor and machine it is recommended to use locking
adhesives such as LOCTITE on the fastening screws.
For outdoor installation or in a hostile environment protect the gearmotor with anticorrosion paint. Added protection may be afforded by water-repellent grease (especially around the rotary seating of seal rings
and the accessible zones of shaft end).
Gearmotors should be protected wherever possible, and by whatever appropriate means, from solar radiation and extremes of weather; weather
protection becomes essential for V5 and V6 mounting positions.
For ambient temperatures greater than 104 °F (40 °C) or less than
32 °F (0 °C), consult us.
Before wiring-up the gearmotor, make sure that motor voltage corresponds to input voltage. If the direction of rotation is not as desired,
invert two phases at the terminals.
If overloads are imposed for long periods of time, or if shocks or danger of jamming are envisaged, then motor-protections, electronic
torque limiters, fluid couplings, safety couplings, control units or other
suitable devices should be fitted.
Where duty cycles involve a high number of starts on-load, it is advisable to utilize thermal probes (fitted on the wiring) for motor protection; a thermal overload relay is unsuitable since its threshold must be
set higher than the motor’s nominal current rating.
Use varistors to limit voltage peaks due to contactors.
Warning! Bearing life, good shaft and coupling running depend
also on alignment precision between the shafts. Carefully align the
gearmotor with the driven machine (with the aid of shims if need be),
interposing flexible couplings whenever possible.
Whenever a leakage of lubricant could cause heavy damages, increase
the frequency of inspections and/or envisage appropriate control devices
(e.g.: remote oil level gauge, lubricant for food industry, etc.).
In polluting surroundings, take suitable precautions against lubricant
contamination through seal rings or other.
For brake or non-standard motors, consult us for specific information.
For IEC frame motor mounting simply observe the following instructions:
− ensure that the mating surfaces are machined under «standard»
rating (UNEL 13501-69; DIN 42955) at least;
− clean surfaces to be fitted, thoroughly;
− check, and, if necessary, lower the parallel key so as to leave a
clearance of 0.004 ÷ 0.008 in (0.1 ÷ 0.2 mm) between its tip and
the bottom of the keyway of the hole; when shaft keyway is without
end, lock the key with a pin;
− check, if necessary that the fit-tolerance of bore-and-shaft end
(standard locking) is K6/j6; the length of the parallel key is to be at
least 0.9 the face width of the pinion;
− ensure that motor bearings are equivalent, in terms of load ratings,
to the ones shown in the table according to motor size;

− mount the spacer (with rubber cement; check that between keyway
and motor shaft shoulder there is a ground cylindrical part of at least
0.06 in) and the pinion (the latter to be preheated to a temperature
of 176 ÷ 212 °F (80 ÷100 °C)) on the motor, locking the assembly
with either a bolt to the shaft butt-end, or a stop collar;
− mount the possible fitting-ring for motor centering onto gear reducer motor mounting flange;
− lubricate the pinion toothing, and the sealing ring and its rotary seating with grease, assembling carefully.
For other details regarding motor mounting, see specific information
and/or consult us.
The replacement of a motor supplied by us with an IEC frame motor1) of
the same power supplied by the Customer is possible only for motors in
mounting position B5.
However, if need be and accepting a reducer machine duty cycle, it is
possible to replace the motors in mounting position B5 with power or
motor power-to-size correspondence not according to standard,
B5R and B5S with motors standardized to IEC of smaller power and
size, if possible, having mating dimensions as stated in ch. 8.
1) NEMA C-Face motors may be fitted in combination with an adapter device supplied as
accessory (see ch. 13 for dimensions and possible combination).
