ABOUT NABTESCO
More than 6 million references for excellent work
"RV" stands for our gear's "rotary vector"
type of construction, and thus also for their
extremely high resilience and precision.
Nabtesco Motion Control – part of the Nabtesco Group – is the world's
largest and most recognized manufacturer of cycloidal gears. Thanks
to their special technology, these precision gears are extremely robust
and, simultaneously, highly precise. The combined engineering expertise
of more than three decades is incorporated in these high-quality gears.
All of this makes them ideal for applications in many high-tech fields.
More than 6 million gears from Nabtesco are in use around the world.
They are used in more than 60 % of the world's industrial robots.
Apart from its proven gear series, a special strength of Nabtesco lies
in its engineering services, with special customer-specific products
and finishes.

ADVANTAGES
• High rated torque of up to 14,715 Nm
• Minimum space requirement
• High shock-load capability (5 times the rated torque)
• High rigidity
• Extreme precision (hysteresis loss < 1 arcmin)
• Low inertia
• Insensitive to vibration
• Extremely low wear
• Long service life
MODE OF OPERATION
Cycloidal gears offer unbeatable advantages
The two-stage reduction of cycloidal gears makes solutions from Nabtesco
Precision so successful. The reason is that the speed is reduced by the
double cams. Vibration is reduced by the two-stage reduction principle
and low inertia. The force is also distributed very evenly, thanks to the
roller cam design, and this contributes to the minimum hysteresis loss
and enormous resistance to shock loading. Consequently, cycloidal gears
are as versatile as they are resilient.
The drive or servomotor is connected to the spur gear stage of the gear-
box via a pinion. The rotating speed reduces at this point relative to the
reduction ratio between the pinion and planetary gear. The planetary
gears are connected to crankshafts which drive the cams using needle
bearings. These cams rotate inside the case which is lined with pins.
The cam has exactly one eccentric section less than the pin ring has pins.
A 360° revolution of the crank shafts therefore causes the cams to rotate
one pin farther, whereby practically all the gear teeth are in continuous
contact with the pins. The rotating movement is then transmitted from the
input shaft to the crankshafts via the spur gear stage, and these then shift
the cams in the pin ring and, consequently, generate a reduced speed with
high precision. This technology enables the RV gears to absorb 5 times the
rated torque in emergency-stop situations without suffering any damage.
The resulting overall reduction is the same as the product of the two
reduction ratios (spur gear stage and eccentric stage).

CUSTOMIZING
Precisely what you need, in the shortest of time frames
09
Developing special solutions and manufacturing custom products
is something we have always done for our clients. Today, we are
going even one step further with customizing.
Whether it is a drive train or a cover, a motor flange or an input gear:
there are many details which one can adapt in order to match our
gears exactly to your application. With a team of experienced develop-
ment engineers and our service team in Farmington Hills Michigan,
we can implement all these requests professionally and quickly.
Often the right combination of existing components is all you need.
In such cases, we can supply you with installation-ready configura-
tions directly from our warehouse.
In other cases it is necessary to alter spurs, holding bores, covers
or drives in order to satisfy the special requirements of your machine
or robotics application. Here, our designers take responsibility for
the engineering and develop a custom solution together with you.

New: the RF-P seriesThe completely newly developed gears of the RF-P series are particularly suitable for fast applications in very small installation spaces. They are eminently suitable for use in arm axes of delta or scara robots or in wheel drives of automated guided vehicles (AGV), for example.
RV-N seriesThe RV-N solid shaft gears with reduced weight at high output torques and high reduction ratios are optimally suited for smaller installation spaces.
RV-C seriesThe RV-C series has a hollow shaft with a diameter of up to 5.43 in which, for example, facilitates the routing of data and power supply cables.
RV seriesThe RV series is the basic version and can be combined with different output supports.
Fast and precise for heavy loadsNabtesco component sets work with extreme precision, extremely low vibrations, and low inertia. Their special construction means they are particularly immune to shock loads and permit high levels of torque.

Compact construction, reduced weight: ideal for robotics
Nabtesco has developed especially compact, lightweight and
powerful gear units: the RV-N series. They are used wherever
high torque ratings are required, yet little space is available. The
compact design is achieved by a main bearing with an integrated
inner ring. The reinforcement of the crankshaft bearing produces
a very high power density. In addition, all gear components have
been optimized using FEM analysis and subjected to the latest
manufacturing processes.

RV Solid shaftCOMPONENT SETS
Low backlash at high reduction ratios
The RV series is the basic version of our precision gears. It enables
the achievement of high reduction ratios. As the force is transmitted
via rollers, RV gears are characterized by higher precision and low
hystere sis loss. RV gears are especially compact, thanks to the
external bearing support, and are capable of determining the output
support themselves. This makes them the ideal solution for integrated
applications which exactly reflect your specifications.

GEARHEADS
21
Quick start with installation-ready gearsNabtesco gearheads are fully-enclosed, filled with lubricant and encapsulated. Because of the pre-installed motor adapter plate and the motor shaft coupling for servomotors, the amount of construction and assembly work required is reduced considerably.
New: the RH-N seriesThe locally-produced, installation-ready gearheads already have an integrated drive pinion and motor flange for all current motor types. That is why they are especially suitable for use in machine tools, modern rotary positioners, and numerous handling applications.
RD_-EThe gearheads have a very lightweight and compact construction.They can also be run with a belt drive or with an attached rectangular pre-stage.
RD_-CThese gearheads have a large hollow shaft to run cable lines through. The hollow shaft rotates at the speed of the drive.
RSRS gears were developed specifically for reliable and precise positioning of heavy loads (up to 9 t).
RA-EA / ECRA-EA / EC solid shaft gears were developed specifically for the exact positioning of chain or disc magazines.
GHThese reduction gearheads for high output speeds are ideal for the automation of robot travel axes, machine tools and conveyor systems.
22
GEARHEADS RH-N Solid shaft
The newest generation of Nabtesco gearheads is based on the compact
RV-N component sets. They were developed specifically for the European
market and are produced locally. The torque rating and precision of the
gears is outstanding, but they are still very compact. Since the drive pin-
ion and a motor flange for all current motor types are already integrated
in the gearhead, it is possible to integrate them in the drive train quickly
and simply. Plug & play!

RS Hollow shaftGEARHEADS
High-precision positioning of even the heaviest loads
The RS gears series was developed specifically for the positioning
of heavy loads. They have an integrated rectangular gear and a robust,
durable construction. As such, they are designed for thrust loads
of up to 9 t and in terms of positioning, they are clearly superior to
conventional cam shaft or worm gears.
ADVANTAGES
• Reliable and precise positioning of heavy loads
• Main bearing permits thrust loads of up to 2.5 t (RS-260A), 5 t (RS-320A) or up to 9 t (RS-900A)
• Hollow shaft (for placement of cables, etc.)
• Cast iron base for robust floor installation
• Easily accessible, right-angle attachment of motor

Gearheads for high output speeds
The reduction gears of the GH series are the "easy-to-use" version
of the RV series. They impress with drive rates of up to 270 rpm
and a shock-load capacity of up to seven times the rated torque.
These gears are typically used to automate robots in travel axes
and conveyor systems.
