SCHOTTEL Debuts EcoPeller with High-torque Gears

Propulsion and steering systems manufacturer SCHOTTEL has unveiled its new EcoPeller (SRE), which it said offers improved efficiency and robustness. Playing a key role here is the new HTG (High Torque Gear) gearbox technology developed and patented by SCHOTTEL.

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

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, SCHOTTEL said. For the same drive torque, it is possible to achieve more streamlined underwater gearbox housings, thereby increasing the hydrodynamic propulsion efficiency. 

In addition to the increased efficiency, customers can expect high reliability and minimized gearbox damage, the manufacturer said. According to SCHOTTEL, the design engineers have designed the gearbox in such a way that the risk of flank fracture or scuffing is reduced, increasing the service life and reliability while reducing servicing costs.
