Ships and marine installations place extreme demands on every technical component: continuous operation under changing climatic conditions, salt-water corrosion, vibrations caused by rough seas, and the simple fact that repairs at sea are simply not an option. The gearbox must function – right from the start, and throughout its entire service life.

CHEMNITZER ZAHNRADFABRIK develops and manufactures specialized gearboxes for maritime applications that can withstand these conditions: corrosion-resistant, sealed, robust and designed for a long service life. From direct drives to control and auxiliary units – we understand the demands of shipbuilding.

Typical requirements for the gearbox

• Corrosion resistance to salt water, moisture and the marine environment
• High levels of sealing and protection against the ingress of water and dirt
• Robustness against vibrations, shocks and dynamic loads caused by sea conditions
• Low-noise operation – particularly relevant for civil and military naval applications
• Reliability over long maintenance intervals
• Compact designs for confined installation spaces on board

What we offer

CHEMNITZER ZAHNRADFABRIK designs marine gearboxes with particular attention to sealing, choice of materials and surface protection. On request, we manufacture using corrosion-resistant materials, with special coatings and to protection classes that meet the requirements of shipbuilding. The design is tailored to the actual operating conditions – including vibration and noise analysis.

Typical gearbox types and application examples

• Radar antenna gearboxes for ships and coastal surveillance systems
• Hydraulic motor gearboxes with generously dimensioned bearings for main propulsion systems
• Auxiliary drives for rudder, anchor and crane controls
• Gearboxes for on-board pumps and fan drives
