Gears & Servo Actuators for Delta Robots

For over fifteen years, WITTENSTEIN has been developing customized gearbox and servo actuator solutions for Delta robots. Thanks to our engineering expertise and a high-performance product portfolio, we guarantee technically and economically optimal drive designs for highly dynamic motion profiles. We are constantly expanding our portfolio with new, customized drive solutions for your robot concept.

Advantages of WITTENSTEIN's drive solutions

Reliability

High reliability of the gearboxes prevents costly machine downtime.

Positioning accuracy

Low torsional backlash and high torsional rigidity ensure maximum positioning accuracy at the tool center point.

Speed

High speed increases machine output.

Low maintenance

The highest quality standards for a long service life and extended maintenance intervals.

Consistently high performance

Consistent torsional backlash throughout the gearbox's service life for consistently high performance.

Low inertia

Further reduction in inertia through the use of a servo actuator.

Wide range of applications

Dry area

For applications such as secondary packaging, end packaging, handling, adhesive bonding, assembly, and intralogistics. Available with either standard or food-grade lubrication (NSF). Take advantage of fast availability—with speedline^®, even within 24 hours.

Spray area (close to the process)

Ideal for process-critical applications in packaging, pharmaceuticals, medical devices, and cleanrooms. Corrosion resistant, without paint or stickers. Comes standard with NSF-certified lubrication. Protection against splashing water (IP65), surface rust, and oxidation, as well as easy cleaning.

Wet area (integrated in the process)

For hygienic primary packaging in direct contact with food. Protection class IP69K, CIP/SIP-compatible, without dead spaces, with a high-quality surface finish. Resistant to aggressive cleaning agents. Fast, safe cleaning and new design flexibility.

Top arm drive

Rotating axis drive (top)

Rotating axis drive (bottom)

WITTENSTEIN's top arm actuators offer maximum dynamics and a long service life thanks to an optimized sealing design and reduced mass moments of inertia.

Discover our products

In this version of the Delta robot, the tool center point is controlled via a central fourth axis. WITTENSTEIN offers a wide range of planetary, right-angle, and servo actuator solutions for this purpose.

Discover our products

In this version of the Delta robot, the rotational axis is driven directly at the tool center point. WITTENSTEIN offers high-performance drives with low weight for this purpose.

Production requirements

Challenges for Mechanical Engineers

Requirements for inputs and components

Production environments require compact, energy-efficient robots that offer high speed, precision, and flexibility. Lightweight construction, protection class, and safety are just as critical as a small footprint and maximum productivity.

Machine builders face the challenge of developing modular, space-saving, and high-performance systems. In doing so, they must meet increasing demands for safety, efficiency, and adaptability while simultaneously reducing costs.

Drives and components must be compact, lightweight, and energy-efficient. At the same time, high dynamics, precision, and reliability are required. Protection class, low-maintenance design, and integration into smart systems play a key role.
