KTR
started up a new test bench for large couplings
covering a performance range up to 500,000 Nm at the
headquarters in Rheine. The test bench allows to calculate
mechanical coupling parameters and perform service life
testing. Testing sample of the initial testing series is a
torque limiter intended to be used on an 8 MW offshore wind
energy plant.
Schaeffler UK has developed flexible training programs
that support the needs of engineers from initial bearing
selection and reliable in-service operation through to
correct maintenance and condition monitoring.
Our courses are delivered by
qualified engineers with a
wealth of expertise in rolling
bearing technology, vibration
analysis and condition
monitoring techniques.
Training takes a modular form,
and courses can be tailored to
meet specific requirements.
Our Facilities
At our Sutton Coldfield site we
have a full range of facilit ies to

The new test bench is provided with an electrical variablespeed drive generating a maximum testing torque of
500,000 Nm via several gears. The torque is measured on
the gear output side through a calibrated measuring shaft
via DMS technology while the twisting angle is calculated
on the drive side through a pulse encoder or a position
sensor which is installed directly on the testing sample. The
data acquired allow to calculate the torsion spring stiffness.
Apart from recording mechanical coupling figures, testing of
component strength and service life is performed on the new
test bench. In addition positive-locking and frictionally
engaged overload systems will be tested and set here.
With the new test bench KTR’s testing capacities in Rheine
have been increased five times. „The availability of such
kind of test bench is particularly important in an age during
which the performance level of drive components for
machinery and plant engineering is continuously increasing“,
Dipl.-Ing. Reinhard Wibbeling, Head of Designing/Research
& Development in KTR explains. „This allows KTR to further
expand its position as the world’s leading manufacturer of
mechanical couplings and overload systems.“
KTR’s test bench for mechanical couplings and overload
systems at the headquarters in Rheine currently comprises
24 rotating and non-rotating test benches operated
hydraulically, servo-hydraulically or electrically. The test
benches cover a test range from 0.2 Nm to 500,000 Nm
and allow for practical testing conditions with dynamic
or static load of the testing sample. The testing capacity
includes determination of coupling parameters, adjustment
of overload systems and endurance testing regarding
component strength and service life.
