Cobots are typically equipped with strain wave gears. The precision gears are small, light, safe, and reliable – which makes them an ideal drive solution for the joints in popular lightweight robots. Those who require the highest standards for performance, quality, individuality, and availability will find the optimal solution at Nabtesco Precision Europe.

Customised strain wave gears for individual cobots

Our zero backlash strain wave gears (manufactured at the Ovalo GmbH branch located in Limburg/Lahn) offer unique functional and power density, as well as a high level of customisation options. Other specifications? An ultra-flat design? Integration of custom features? No problem. We can tailor performance, geometry, material, and interfaces to the exact requirements of your particular application. This gives you maximum freedom in the design of your cobot without having to make any compromises.

Compact precision gears of excellent quality:

• Absolute zero backlash
• Compact and lightweight design
• Optional hollow shaft – ideal for feed-through of cables and hoses
• Specifically configurable backdriving torque
• High reliability
• Quiet operation
• High level of customisation
• Maintenance-free throughout the entire service life

Automation made easy

Whether for handling, assembly, loading, palletising, or packaging: The future belongs to cobots. The market has been expanding for years, and cobots are being used in ever more diverse applications. And the trend is on the rise. No wonder. The convenient robot arms combine performance, compactness, cost-effectiveness, and user friendliness to create a flexible, efficient, and reliable automation solution. Especially small and mid-sized industrial and craft enterprises benefit from features such as easy integration, user-friendly handling, and intuitive operation.

Cobots – multi-faceted tools for automation

• Intuitive handling: Easy to install and easy to program
• Broad application spectrum: Flexible and versatile
• Low space requirements: Compact design, minimal footprint
• Seamless integration in existing production processes
• Collaborative: Safe interaction with people, without external safety technology
• Outstanding cost-effectiveness with a fast return on investment (ROI)

Gears are a core technology

However: Every robot is only as good as its gears. As torque and speed converters they are the heart of the system, so to speak; they crucially affect performance data and kinematics. Without precise gears, a lightweight robot cannot achieve pin-point positioning. Special care is therefore needed in the choice and design of the gears.

Compact, zero backlash precision gears for every requirement

We have the ideal solution for every challenge. Our flexible modular product system and our extensive engineering services open up virtually unlimited possibilities for you, as the basis for innovative cobot drive concepts. Depending on the customer’s integration capabilities we use different versions of our strain wave gears to create solutions that are optimally tailored to your requirements.

Our product portfolio at a glance:

• Gear sets: The most basic version
• Gear sets plus: Ready to install, with rigid gear output shaft
• Gear units: Completely enclosed, including rigid output and input bearing and seal system
• Actuators: Complete systems, typically consisting of a gear set, bearing, housing, and electric motor

We also offer digital strain wave gears as an extremely compact solution for intelligent automation.
