VSP 18

The VSP 18 is a coaxial direct‑drive propulsion gearbox from Voith Schneider that transmits up to 1 800 kW at 200 rpm directly to a Voith‑Schneider propeller without reduction. As a Reduction Gear, it is normally installed between a propulsion engine or motor and the shaft line, reducing or adapting rotational speed and transmitting torque to the propeller. In that role, its primary purpose is to match prime-mover speed and torque to the propulsion shaft while providing the required clutching or reduction arrangement. Single-stage, multi-stage and epicyclic marine gearboxes differ in gear geometry and layout, but all depend on alignment, tooth contact, bearings and clean pressurized lubrication. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
