Aerospace
When there is no margin for error – not even in the gearbox.

In the aerospace sector, every component is a safety-critical component. Specialized gearboxes or precision-machined gear parts control flaps, rotor blades, antennas, satellite mechanisms and engine components – often subject to extreme temperature fluctuations, high accelerations and under conditions that make maintenance simply impossible.

CHEMNITZER ZAHNRADFABRIK develops drive technology for aerospace applications that meets the most stringent requirements for precision, lightweight construction and reliability. Every gram counts. Every tooth flank does too.

Typical requirements for the gearbox

• Maximum precision with minimal backlash and maximum torsional stiffness
• Lightweight construction – weight optimization combined with high strength
• Reliability over long operating periods without the possibility of maintenance
• Robustness against extreme temperature fluctuations and vibrations
• Complete quality documentation and traceability of all components
• Operation in a vacuum or inert gas atmosphere on request

What we offer

We design aerospace gearboxes with a particular focus on weight optimization, material selection and manufacturing quality. Our design engineers are experts in designing low-backlash gearboxes with high torsional stiffness – a crucial factor for precise positioning and reliable operation in safety-critical systems. Comprehensive manufacturing documentation is a given.

Typical gearbox types and application examples

• Low-backlash spur and planetary gearboxes for flap control systems and actuators
• Lightweight gearboxes for satellite mechanisms and antenna alignment
• Bevel gearboxes for helicopter drives and auxiliary power units
• Custom gearboxes for test bench applications in aerospace development
