Cycloidal servo gears: advantages & applications

When it comes to highly dynamic positioning applications, servo gears are the measure of all things. That is undisputed. But there is one thing you should ask yourself: Does your gear technology really achieve maximum performance and reliability? Take full advantage of your potential for efficiency! Cycloidal servo gears feature extremely high torsional rigidity and minimum backlash and can significantly boost the performance of your servo applications.

Ever shorter cycle times increase the demands placed on servo gearboxes used in the production industry. The motto: more speed, more precision, and a more compact design. To meet these stringent requirements and to remain competitive, manufacturers need future-proof solutions – such as our cycloidal servo gears. The special design of these gear systems enables high speeds and accelerations combined with excellent positioning and rotational speed accuracy – which makes them ideal for use in highly dynamic applications.

Servo gears for the most stringent requirements

Our servo gears are designed for maximum precision and dynamics, as well as high torsional rigidity and minimum backlash. The increase in backlash is minimal even after long-term use. The two-stage reduction principle results in excellent performance with respect to smooth operation, as well as high repeatability and path accuracy. The integrated angular ball bearings absorb axial and radial loads as well as bending moments, and provide for high resistance to impacts and overloads.

Advantages of our servo gears:

• Hysteresis loss < 1 arcmin. The purely mechanical backlash is even as low as 0.1–0.2 arcmin. By way of comparison: A precision planetary gear has purely mechanical backlash of 1-3 arcmin.
• High torsional rigidity
• Excellent repeatability and path accuracy
• Transmission of very high torques due to high acceleration parameters
• Low inertia
• Minimal vibrations
• Low-wear design for a long life
• Compact and lightweight

Cycloidal servo gears

As a result of the continuing trend toward automation and the increasing use of servo axes, our servo gears are conquering more and more fields of application, especially in handling and automation technology, where they have become indispensable. Meanwhile, well over 13 million Nabtesco gearboxes are in use worldwide, delivering outstanding performance in numerous high-tech applications.

No matter the technology – solid or hollow shaft, coaxial gears, parallel shaft gears, bevel gears, custom gears or a standard solution – cycloidal servo gears will bring your automation to a new level. The result: faster processes, higher productivity, better product quality, and lower costs.

Our servo gears are ideal for:

• Handling
• Machine tool construction
• Medical technology
• Welding
• Packaging industry

Extensive portfolio of precision gears

Cycloidal gears are a guarantee for precision, dynamics and reliability, and are long considered a key technology for efficient drive concepts. We offer numerous solutions for highly dynamic servo applications. The Neco? and Neco?HT series are economical solid shaft plug-and-play gearboxes. If a hollow shaft is required, the versatile servo gearboxes of the RD-C series are the top choice. Rotational positioning is improved by our powerful rotary indexers of the RS series and automated guided vehicles (AGV) attain omnidirectional mobility by using our fully integrated decentralised drive concept with a Mecanum wheel on the basis of RVW gears.

Servo gearboxes are designed for fast and easy integration in the drive train and for operation with all standard servo motors. Engineering and installation costs are greatly reduced by the built-in motor adapter plate and the motor shaft coupling for servo motors.
