Medicine
Precision that makes life easier – and sometimes saves lives.

Medical devices place exceptional demands on the drive technology used: they must be extremely precise, absolutely quiet and – depending on the application – sterilizable or biocompatible. Whether medical robots, imaging equipment, surgical instruments or patient aids: the gearbox must not introduce noise, play or unreliability into the system.

CHEMNITZER ZAHNRADFABRIK develops specialized gearboxes for medical technology applications that meet these requirements – small, precise, quiet and made from materials that withstand the demands of medical technology.

Typical requirements for the gearbox

• Maximum positioning accuracy and minimal rotational play
• Low-noise and vibration-free operation in sensitive environments
• Biocompatible or sterilizable materials and surfaces
• Compact and weight-optimized designs for hand-held or portable devices
• Long service life with low-maintenance or maintenance-free designs
• Complete documentation for regulatory approval procedures

What we offer

We design medical technology gearboxes with a particular focus on zero backlash, low noise and material selection. Integrating them into confined spaces – typical of medical devices – is a familiar challenge for our designers. On request, we provide complete manufacturing documentation for regulatory approval procedures.

Typical gearbox types and application examples

• Low-backlash planetary gearboxes for medical robotic arms and actuators
• Miniature gearboxes for surgical instruments and endoscopy systems
• Drives for imaging equipment (CT, MRI positioning, X-ray systems)
• Gearboxes for laboratory automation and pipetting robots
• Drive solutions for patient aids and rehabilitation technology
