ROBUS in-line helical gearbox
index
pag. 2-3
Except Robus 20,
all Robus sizes have
a screw-on lifting
eyebolt
TECHNICAL CHARACTERISTICS
Uniquely contoured, rigid, precise,
monobloc, cast iron Body, Base
and Flange ensure extreme robustness.
easy to examine and maintan.
Minimum maintenance
requirement
IEC flange and hollow
shaft.
Choice of hollow input
flanges permits direct
mounting of any standard
motor
flexible mounting
robust
A large top cover in light
weight aluminium alloy facilitates the inspection
Modular design with
detachable output flange
and foot base allows easy and
quick conversion between
foot and flange mounting
versatile
List of components Robus-2
(2 reduction stages)
pag. 4-5
Various detachable
foot bases in solid
cast iron make Robus interchangeable
with any other gearbox brand
+ ZZ autolubricating bearings on
input and output shaft
+ Body design which allows the
same quantity of oil to lubricate the
gears in any mounting position
+ 6 interchangeable plugs, including one breather plug and a level
plug
+ mechanical parts locked in their
positions by circlips and spacers.
This also ensures better absorbtion of axial thrust and prolongs
the life of bearings
Shafts are made from 42CrMo4 steel and tempered to reach
a hardness of 2-5 HRC, thus increasing their capacity to
withstand shearing stresses.
If the mechanical robustness and the service factor of an
helical gearbox are mainly influenced by the centres distance
of the last stage, Robus confirms to be very Robust (see
"X2" at page 19)
Single stages ratios between 2 and 6, together with proper
gears sizes, result mathematically in higher teeth number
and size (module) of each wheel and a better fractioned load
among the reduction stages. That influences both durabilty
and torque transmission capability
Dual bearing support on the input shaft assures precise
alignment of the first stage gears and reduces vibrations
and consequent gear wear
Intermediate shaft is rigidly supported by bearings, with
no overhang wheel, thus imparting greater flexural strengh
and better meshing. This increases the overloading capacity
and takes to lower noise
Smaller overhang of output shaft from supporting bearing in
order to withstand higher radial loads
Abounding bearings size (pages 5 and 7), in order to withstand
higher loads

The output torque can be calculated with
the following formula:

Thanks to such oil quantity, and to these 3 characteristics, each Robus can be
mounted in ANY mounting position, with no need to specify it in the order, thus giving
big advantages in the stock management and lead time

Torque demand Mr2 [Nm]
Torque calculated based on application
requirements. It must be b Mn2 of the
chosen BOX unit.
Input power Pn1 [kW]
This is the power value of the motor applied to the input shaft and corresponding
to a certain input speed n1, a service
factor fs=1 and a duty service S1.
It is even possibile to calculate the motorsize necessary by using the formula:
Pn1 [kW]
+ ZZ autolubricating bearings on input and output shaft
6 interchangeable plugs, including one breather plug and a level
plug. Level and breather plug must be positioned according to
this chart
=
Mr2 · n2
9550 · H
Since the value calculated in this way
could not really correspond to an input
power actually available in the IEC standardised motors, it will be necessari to
choose, among the input powers available, the one which is immediately higher,
checking this in the Motive catalogue of
the motors.
Efficiency H [%]
An inherent factor in the selection wormgear boxes is the efficiency h, defined as
the ratio between the mechanical power
coming out from the output shaft, and
the power in the input shaft:
H=
mechanical parts locked in their positions by circlips and spacers.
This also ensures better absorbtion of axial thrust and prolongs
the life of bearings

Dual bearing support on the input shaft
ensures precise alignment of the first
stage gears and reduces vibrations and
consequent gear wear
Compared to fractioned or Aluminium
body, the monobloc cast-iron body of
Robus provides higher rigidity and mechanical robustness.
An intermediate shaft rigidly supported
by 3 bearings instead of 2, with no overhang wheel, imparts greater flexural
strengh and smoother meshing
Use of high strength steels like 15CrMo4
and case hardening to 58 ±2 HRC reduce the wear rate in wheels. All wheels
are profile ground to Din 3962 class 6
accuracy
Oversized bearings (see Robus bearings
list at pages 5 and 7), allow the gearbox
to withstand higher operating loads
Shafts are made from 42CrMo4 steel and
tempered to reach a hardness of 23-35
HRC, thus increasing their capacity to
withstand shearing stresses and torsion
effect.
Smaller overhang of output shaft from
supporting bearing in order to withstand
higher radial loads

The efficiency in helical gearboxes is
mainly determined by the gearing and
bearing friction.
The efficiency of Robus varies with the nr of
stages: it's 94% when the reduction stages
are 3, 96% when the stages are 2.
The starting efficiency is always less than
the efficiency at rated speed

TECHNICAL DATA
LUBRICATION
The oil quantity is suitable for any mounting position.
Robus
Optimal ratios (between 2 and 6) in the
several stages, together with appropriate centre distances, result in higher
number of teeth and size (module) of
each wheel and better torque transmission fractioning through various stages.
This improves the overall durability.
Amongst all parts, the last stage gears
are subjected to highest mechanical
stresses. Higher centre distance whicn
in turn results in higher module considerably increases the service factor.

Offered service factor
Which features determine the service factor offered by an helical gearbox?
The service factor of a gearbox is its capacity to withstand operating overload, frequency at which it can
be overloaded, number of starts, duration of operating time, and resistance to mechanical shocks and vibrations. Thus, higher the service factor, greater is the possibility of trouble-free operation and increased
life. Without aiming to be completely exhaustive, we list here the main features that influence the service
factor:

Output speed n2 [rpm]
It is the rotation speed of the output

Service factor fs
It is a numeric value describing the BOX

the daily working hours h/d
the load classification (see table 2),
and then the moment of inertia of the
driven masses.

In the graph 2, the service factor fsr
required by a certain application can be
attained, after having selected the proper
“daily working hours” (h/d) column, by intersecting the number of starts per hour
(s/h) and one of the a, b or c curves. The

If, after the selection of the right Mr2 and
n2 in the following performance tables,
you don’t find a BOX unit whose service
factor fs is ≥ of the requested one fsr,
you can choose a BOX unit in which Mn2
> Mr2.
In fact, in order to satisfy fsr, you can choose another BOX unit whose output torque
is ≥ Mc2 output torque, where:
Mc2 = Mr2 · fsr
Note: This rule is valid only if the new
BOX unit that has been selected in this
way has a service factor fs ≥ 1 in the
performance tables.
From another point of view, the value of fs in
the performance tables refers to a case in

will be accepted only in exceptional
cases; however returns of goods
already used to credit or replace
won’t be accepted in any case.
The guarantee shall be effective for
all Motive products, with a term
of validity of 12 months, starting
from the date of shipment.
The guarantee shall be subject
to specific written request for
Motive to take action, according
to statements, as described at
20
the paragraphs herein below. By
virtue of aforesaid approval, and
as regards the claim, Motive shall
be bound at its discretion, and
within a reasonable time-limit,
to alternatively take the following
actions:
a) To supply the Buyer with
products of the same type and
quality as those having proven
defective and not complying with
agreements, free ex-works; in
aforesaid case, Motive shall have
the right to request, at Buyer’s
charge, early return of defective
goods, which shall become Motive’s property;
b) To repair, at its charge , the
defective product or to modify the
product which does not comply
with agreements, by performing
aforesaid action at its facilities;
in aforesaid cases, all costs regarding product transport shall
be sustained by the Buyer.
c) To send spare parts free of
charge: all costs regarding product transport shall be sustained
by the Buyer.
1.3. The guarantee herein shall
assimilate and replace legal guarantees for defects and discrepancies, and shall exclude any
other eventual Motive liability,
however caused by supplied products; in particular, the Buyer
shall have no right to submit any

enforcement of any further claims,
as of the date the guarantee’s
term of validity expires.
ARTICLE 2
CLAIMS
ARTICLE 4
PAYMENT
2.1. Claims, regarding quantity,
weight, gross weight and colour,
or claims regarding faults and defects in quality or compliance, and
which the Buyer may discover on
goods delivery, shall be submitted
by a max.7 days of aforesaid discovery, under penalty of nullity.
4.1. Any delayed or irregular payments shall entitle Motive to cancel ongoing agreement, including
agreements which do not regard
the payments at issue, as well as
entitling Motive to claim damages,
if any. Motive shall, however, have
the right, as of payment’s due date
and without placing in arrears, to
claim interest for arrears, to the
extent of the discount rate in force in Italy, increased by 12 points.
Motive shall also have the right to
withhold material under repair for
replacement. In the case of failed
payment, Motive shall have the
right to cancel all guarantees of
materials, as regards the insolvent Client.
ARTICLE 3
DELIVERY
3.1. Any liability for damages
ensuing from total or partial delayed or failed delivery, shall be
excluded.

MOTIVE CAN CHANGE THE
CHARACTERISTIC OF THE SOLD
ITEMS ON HIS FIRM OPINION AND
IN EVERY MOMENT.
TECHNICAL CHARACTERISTICS
Uniquely contoured, rigid, precise,
monobloc, cast iron Body, Base
and Flange ensure extreme robustness.
robust
A large top cover in light
weight aluminium alloy facilitates the inspection
Modular design with
detachable output flange
and foot base allows easy and
quick conversion between
foot and flange mounting
versatile
Various detachable
foot bases in solid
cast iron make Robus interchangeable
with any other gearbox brand
patented
Except Robus 20,
all Robus sizes have
a screw-on lifting
eyebolt
Minimum maintenance requirement.
All sizes are supplied with long-life synthetic oil.
IEC flange and hollow
shaft.
flexible mounting
Choice of hollow input
flanges permits direct
mounting of any standard
motor
Unique construction of Robus
makes it possible to mount any
size in any position.
This flexibility is achieved by:
+ ZZ autolubricating bearings on
input and output shaft
+ 6 interchangeable plugs, including one breather plug and a level
plug
+ mechanical parts locked in
their positions by snap rings and
spacers.This also ensures better
absorbtion of axial thrust and prolongs the life of bearings
engineered for higher reliability
Easy to examine and maintan.
Use of high strength steels like 15CrMo4 and case hardening
to 58 ±2 HRC reduce the wear rate in wheels. All wheels
are profile ground to Din 3962 class 6 accuracy for low noise
and high efficiency.
Shafts are made from 42CrMo4 steel and tempered to reach
a hardness of 23-35 HRC, thus increasing their capacity to
withstand shearing stresses.
If the mechanical robustness and the service factor of an
helical gearbox are mainly influenced by the centres distance
of the last stage, Robus confirms to be very robust (see "X2"
at page 19)
Single stages ratios between 2 and 6, together with proper
gears sizes, result mathematically in higher teeth number
and size (module) of each wheel and a better fractioned load
among the reduction stages. That influences both durabilty
and torque transmission capability
Dual bearing support on the input shaft assures precise
alignment of the first stage gears and reduces vibrations
and consequent gear wear
Intermediate shaft is rigidly supported by 3 bearings, with
no overhang wheel, thus imparting greater flexural strengh
and better meshing. This increases the overloading capacity
and takes to lower noise
Smaller overhang distance of output shaft from supporting
bearing in order to withstand higher radial loads
Abounding bearings size (pages 5 and 7), in order to withstand
higher loads

After adapting the oil quantity, each Robus can be mounted in ANY position, thus
giving big advantages in the stock management and lead time, thanks to the following
3 characteristics:
ZZ autolubricating bearings on input and output shaft
breather plug
6 interchangeable plugs, including one breather plug and a level
plug. Level and breather plug must be positioned according to
this chart
mechanical parts locked in their positions by circlips and spacers.
This also ensures better absorbtion of axial thrust and prolongs
the life of bearings

technical data
Rated output torque Mn2 [Nm]
Torque output transmissible under uniform loading and referred to the input
speed n1 and the corresponding output
speed n2.
The output torque can be calculated with
the following formula:
P [kW] · 9550 Mn2 = n1
·η
n2 Torque demand Mr2 [Nm]
Torque calculated based on application
requirements. It must be ≤ Mn2 of the
chosen BOX unit.
Input power Pn1 [kW]
This is the power value of the motor applied to the input shaft and corresponding
to a certain input speed n1, a service
factor fs=1 and a duty service S1.
It is even possibile to calculate the motorsize necessary by using the formula:
Mr2 · n2
Pn1 [kW] = 9550 · η
Since the value calculated in this way
could not really correspond to an input
power actually available in the IEC standardised motors, it will be necessari to
choose, among the input powers available, the one which is immediately higher,
checking this in the Motive catalogue of
the motors.
Efficiency η [%]
An inherent factor in the selection wormgear boxes is the efficiency h, defined as
the ratio between the mechanical power
coming out from the output shaft, and
the power in the input shaft: Pn2
η=
Pn1
The efficiency in helical gearboxes is
mainly determined by the gearing and
bearing friction.
The efficiency of ROBUS varies with the nr of
stages: it's 94% when the reduction stages
are 3, 96% when the stages are 2.
The starting efficiency is always less than
the efficiency at rated speed
Gear ratio i
It is the relationship of the input speed
n1and the output speed n2
graph 2
n1
i =
n 2
In the combined, the total ratio is the
result of the product of the ratio of the
two single boxes.
Input speed n1 [rpm]
It is the speed the BOX unit is driven
at.
Output speed n2 [rpm]
It is the rotation speed of the output
shaft.
Service factor fs
It is a numeric value describing the BOX
unit service duty. With unavoidable approximation, it takes into consideration:
the daily working hours h/d
the load classification (see table 2),
and then the moment of inertia of the
driven masses.
The number of starts per hour s/h
The presence of brake motors, for which it is necessary to multiply for 1.12
the service factor value deducted by
the graph 2.
The significance of the application in
terms of safety, for example lifting of
parts
In the graph 2, the service factor fsr
required by a certain application can be
attained, after having selected the proper
“daily working hours” (h/d) column, by intersecting the number of starts per hour
(s/h) and one of the a, b or c curves. The
curves a, b and c are linked with the load
classification described in the table 2.

If, after the selection of the right Mr2 and
n2 in the following performance tables,
you don’t find a BOX unit whose service
factor fs is ≥ of the requested one fsr,
you can choose a BOX unit in which Mn2
> Mr2.
In fact, in order to satisfy fsr, you can choose another BOX unit whose output torque
is ≥ Mc2 output torque, where:
Mc2 = Mr2 · fsr
Note: This rule is valid only if the new
BOX unit that has been selected in this
way has a service factor fs ≥ 1 in the
performance tables.
From another point of view, the value of fs in
the performance tables refers to a case in
which the effective torque requested by the
application Mr2 matches perfectly with the
one appearing on the catalogue Mn2.
Whenever the torque indicated in the
performance table is higher than the requested one, the offered service factor of
the performance table can be increased
according to the formula:
f on the table · Mn2 on the table
fs real = s
Mr2
The value of fs calculated in this way must
be ≥ fsr.

technical data
Offered service factor
Which features determine the service factor
offered by an helical gearbox?
The service factor of a gearbox is its capacity
to withstand operating load and overloads,
a certain number of starts, the duration
of operating time, and mechanical shocks
and vibrations. Thus, higher the service
factor, greater is the possibility of troublefree operation and increased life. Without
aiming to be completely exhaustive, we list
here the main features that influence the
service factor:
12
Amongst all parts, the last stage gears
are subjected to highest mechanical
stresses. Higher centre distance which
in turn results in higher module considerably increases the service factor.
ROBUS excels in the area (see measures
at page 22)
Dual bearing support on the input shaft
ensures precise alignment of the first
stage gears and reduces vibrations and
consequent gear wear
Compared to fractioned or Aluminium
body, the monobloc cast-iron body of ROBUS provides higher rigidity and mechanical robustness.
An intermediate shaft rigidly supported
by 3 bearings instead of 2, with no overhang wheel, imparts greater flexural
strengh and smoother meshing
Use of high strength steels like 15CrMo4
and case hardening to 58 ±2 HRC reduce the wear rate in wheels. All wheels
are profile ground to Din 3962 class 6
accuracy
Oversized bearings (see ROBUS bearings list at pages 5 and 7), allow the
gearbox to withstand higher operating
loads
Shafts are made from 42CrMo4 steel and
tempered to reach a hardness of 23-35
HRC, thus increasing their capacity to
withstand shearing stresses and torsion
effect.
Mechanical parts locked in their position
by snap rings and spacers. This ensures
better absorbtion of axial thrust and
prolongs the life of bearings
Optimal ratios (between 2 and 6) in the
several stages, together with appropriate centre distances, result in higher
number of teeth and size (module) of each
wheel and better torque transmission
fractioning through various stages. This
improves the overall durability.
Smaller overhang of output shaft from
supporting bearing in order to withstand
higher radial loads
