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.

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.
