Torque Limiting and Safety Couplings SK
Precision Safety Couplings / Torque Limit Series SK up to 2800 Nm
Taking
up the challenge for greater technical demands in modern
machine design and construction, R+W has developed
the unique reliable Models SK Safety Couplings /Torque Limiters.
Torque overload protection is often overlooked in machine design until something jams resulting in expensive damage and down time. The R+W Safety Coupling Series SK was developed specifically for this purpose. It uses a reliable ball detent system that is absolutely backlash-free and will disengage within 1 to 3 milliseconds when an overload is detected.
Four versions are available including a single position, multi-position, load holding, and full disengagement. These Safety Couplings are preset in the factory to a customer specified disengagement torque and can be adjusted in the field after installation.
These unique Safety Couplings
Series SK3 are manufactured
with a stainless steel bellow exhibiting very high torsional
rigidity with zero backlash. The important feature of this
design is the fact that the
bellow can compensate for axial, angular, and lateral mis-alignment
simultaneously while also providing torque overload protection.
The conical clamping
hub provides the highest shaft holding strength and incorporates
integrated back-off screws for dismounting.
The SK Safety Couplings are available for a torque range
of 5 to 2800 Nm. Both shaft hubs are custom bored for shaft
sizes of 10 to 100 mm.
