Renk Offers Literature On RCF Generator Gears

Renk of Augsburg, West Germany, has available new literature on the Renk-Constant-Frequency (RCF) gear unit. The publication states that all shipowners ask for more cost-effective power generation onboard than was formerly possible, and one answer is the Renk- Constant-Frequency gear "RCF System." The RCF System features a differential epicyclic gear and a Renk Controller. An epicyclic gear unit with hydrostatic or electric superposition enables the generation of economic current onboard by the large diesel engine of the main propulsion plant.

The literature mentions that the RCF System constitutes a design solution that offers definite economical advantages, especially in plants incorporating low-speed diesel engines and fixed-pitch propellers.

However, the RCF System is also used with controllable-pitch propellers and in medium-speed diesel engine propulsion systems.

With the aid of the RCF System, the economy of the low-speed marine diesel engine is extended to include power generation onboard.

Installation variants of the RCF System are listed, with diagrams, such as parallel, vertical, rectangular, Z-arrangement as shaftmounted generator, U-arrangement as shaft-mounted generator, and special solutions. The mode of functioning of the RCF System and the design of the system are also discussed and illustrated with drawings, diagrams, and charts. Advantages of the RCF System are discussed thoroughly, and the two variants of the Renk-RCF gear unit are detailed along with diagrams.
