Geislinger Delivers Record Sized Coupling

Geislinger GmbH recently delivered its biggest torsional elastic coupling — a coupling with an outer diameter of 2.8- m and a weight of 36.3 tons. The coupling will be built into the drive line of a VLCC tanker, with an energy saving counter-rotating double propeller. More than 2,000 single parts were produced in the Geislinger works in Bad St.

Leonhard and assembled in the works in Salzburg. The coupling transmits half of the 27.160 KW engine power at 74 rpm and in this way protects the gear box, which changes the direction of rotation for the backwards running propeller.

This causes the energy of the swirling water in the gushing of the propeller to be used and therefore the degree of effectiveness is increased by about 14 percent. About 10 years ago three ships with this innovative CRP system plus Geislinger coupling were supplied from the same shipyard. All these systems were produced in Japan the largest one is scheduled to be built.

In order to monitor the function of the world's largest coupling BE 280/60/140U Geislinger has delivered a highly modern electronic system called Geislinger Monitoring GMS Mark 4.

This equipment is supplied with sensor signals and assists the ship owner, among other things, to save maintenance costs.
