Gearheads

Nexen’s revolutionary Harmonic Gearhead (HG) is the ideal combination of size and precision. The Harmonic Gearhead integrated with Nexen’s Roller Pinion System creates a true backlash-free solution from the motor to the driven load, delivering high load capacity in a compact package. With up to a 70% reduction in length over standard gearheads, machine designers have greater opportunities available with this space-saving product.

Gearheads are a replacement for non-rigid, bulky, high-ratio gearboxes. Utilizing zero-backlash strain wave technology for maximum system rigidity and space-saving allows for the Harmonic Gearhead to:

• Operates in less than half the space

• Zero backlash directly to the motor

• Quiet operation

• Output torque up to 1,057 Nm

• Thrust up to 6,000 N on units with integrated pinion output

• Rotational accuracy of ± 45 ArcSec and linear accuracy of ± 25 μm on units with an integrated pinion on the output

• Rotational repeatability of ± 10 ArcSec and linear repeatability of ± 7.5 μm on units with an integrated pinion on the output

• Rugged cross-roller output bearing supports moment loads up to 1,590 Nm

Nexen's Gearheads are ideal for applications like:

• Aerospace
• Robotics
• Semiconductor
• Factory Automation
• Medical/Surgical
• Machine tools
• Robots and robotic arms
• Rack and pinion systems
• General industrial positioning
