SCHOTTEL Propulsion Systems with Innovative HTG High-Torque Gears

Higher performance, lower costs

HTG is a highly-efficient, robust and reliable gearbox with an ideal gearing geometry. It has low maintenance requirements, reduces servicing costs and also allows streamlined housings for improved hydrodynamic properties.

The new SCHOTTEL EcoPeller (SRE) has just been unveiled to the public. It is distinguished by its utmost efficiency and robustness that are unrivalled on the market. The new HTG (High Torque Gear) gearbox technology developed and patented by SCHOTTEL plays a significant role here.

Streamlined gearbox housings

The HTG enables bevel gears of the same dimensions to transmit up to 15 percent higher drive torque with the same safety margins required by the classification societies, not to mention SCHOTTEL’s own internal standards. For the same drive torque, it is possible to achieve significantly more streamlined underwater gearbox housings, thereby increasing the hydrodynamic propulsion efficiency.

Robust and reliable design

In addition to the increased efficiency, customers also appreciate the high degree of reliability and minimized gearbox damage. The design engineers have designed the gearbox in such a way that the risk of flank fracture or scuffing is considerably reduced. This increases the service life and reliability and reduces servicing costs.

Production of the ideal geometry

With the HTG, SCHOTTEL has revolutionized gearbox technology with a view to the special requirements of shipbuilding. State-of-the-art milling and calculation methods enable shapes that boost performance and increase reliability.
