Bespoke configurations of modular gearbox

At SMM 2012 in Hamburg, German marine gear systems manufacturer RENK AG revealed its new line-up of standard gear units, the T²RECS.

The T²RECS is notable for its compact size

This gear unit series addresses the most important application criteria of single marine gear units. Despite the high degree of standardization, there is still scope for individualised configurations to suit customer needs. The T2RECS is of modular design and particularly suitable for OSVs, commercial workboats including tugs, and fishing vessels.

The range includes seven sizes with centre distances of 400mm to 710mm. With a mean of 600 to 1,200rpm, the units are rated between 500kW and 5,000kW.

Notable for its compact size and ruggedness, the T²RECS features simple, standardized add-on modules allowing gear units to be configured to specific requirements within the modular system. Included is the option of hydraulic multi-disc clutches, which have proven themselves as rugged and durable even under extreme conditions.

Various configurations are feasible:

  • Power Take-Off (PTO): for driving a generator for onboard power
  • Power Take-In (PTI): for additional booster power from generator
  • Power Take Home (PTH): redundant propeller drive system via a generator/electric motor

Another advantage is the split housing design for easy maintenance. Quick access to the pinion shaft and multi-disc clutch is an added benefit when servicing. The pressure bearing at the wheel shaft can be replaced without opening the housing. The latest filtering technology ensures sustained oil purity and longer bearing life. All of the hydraulic components are easy to dismantle during maintenance.
