Sailboat Propeller-Shaft Couplings Cruising World

Jun 19, 2019 · Tapered couplings are ­popular on large horsepower applications and are the undisputed Cadillac of shaft-connection methods. Relying on the same principal used for the propeller-to-shaft interface, a cone-shaped hole in the coupling mates with a precisely machined cone-shaped male taper on the end of the prop shaft.

Flexible Propeller Shaft Couplings

The R and D Marine flexible coupling range is an extremely popular choice of flexible shaft coupling, due to the competitive pricing and the simple to fit and maintain design. R&D flexible shaft couplings are designed for boat propeller shafts, providing isolation from both vibration and engine noise.

Shaft Couplings - R.E. Thomas Marine Hardware

Tapered couplings are secured the same way a propeller is connected to a propeller shaft (hence the term “double tapered” shaft).   The shaft is cut with a taper to match the tapered face of the coupling.   The coupling is then pulled on to the shaft by tightening the nut on to the threaded end of the shaft.

Propeller shaft coupling flange - Wärtsilä

Propeller shaft coupling flange. For connecting the propeller shaft with the intermediate shaft, a hydraulic coupling flange is used. To fit the flange, high-pressure oil of more than 2000 bar is injected between the muff and the coupling flange by means of the injectors in order to expand the muff.

Drives for propeller shafts - VETUS

Drives for propeller shafts Drives for propeller shafts The VETUS DRIVE (Type VDR) has a combination of a self-aligning thrust bearing and a double acting constant velocity joint. The propeller thrust is absorbed by the inbuilt thrust bearing allowing the engine to be set up on softer mountings, resulting in lower vibration and transmitted noise.
