High torque clamping sets provide safety
solution
When a container ship running at 19 knots changes direction, high forces are effective on the entire rudder machine and these can cause critical safety issues
The connection between the rudder shaft or tiller and the rudder yoke plate making the rudder move has to be designed in a way to compensate for high forces For such a critical combination, high torque clamping sets from the CLAMPEX programme such as series 400, have proven their worth

Rotex is KTR's most famous coupling series and is available in numerous variations including combinations with overload systems.
Shrouded coupling promises leak-free links
A permanent-magnet synchronous coupling provides semihermetic contactless torque transmission.
The KTR series 400 was developed specifically for highest loads, high alternating torques and big torsional forces.
In spite of their ability to accept extremely high loads, the clamping sets are self centering and easy to assemble.
As a consequence, they are a low cost and safe alternative to shafts with a taper shaft end, the machining of which is expensive.
Well known manufacturers of rudders have realised the benefits provided by the use of clamping sets and consequently they cooperate with KTR with regard to the configuration of the connection elements on the interface between the tiller and rudder yoke plate.
KTR offers them an extensive programme of shaft hub connections for high quality applications in marine technology.
For example; the clamping sets KTR 400 are available with a saltwater proof coating for outboard applications.
In this case they are nitrocarburised by means of a QPQ surface treatment, the screws being supplied in a design with Geomet coating.
Since the steel material with surface treatment is able to accept a considerably higher load than stainless steel, this type allows more compact designs on outboard applications.
Apart from clamping sets, KTR offers other power transmission components to manufacturers of marine drives.
For example, the company has developed a RADEX-N steel lamina coupling with a special lamina for two manufacturers of boat engines/marine diesel engines.
The coupling is used between the two mass flywheel of the diesel engine and the star drive on the single cardan shaft.
It compensates for axial and angular misalignment, supports the cardan shaft and is able to compensate for axial displacements by the spline shaft in the hub.
In this way it assures a running free from vibrations and a long service life of the drive.
