Still a smaller possibility: mechanical Torque Limiters and Safety Couplings
Precision Torque Limiting Clutch / Torque Limiter Series SK2 with clamping hub
Taking
up the challenge for greater technical demands in modern machine
design and construction, R+W has developed the unique reliable Model
SK2 Safety coupling.
Torque overload protection is often overlooked in machine design until something jams resulting in expensive damage and down time. The R+W Series SK2 safety coupling 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 free wheeling. These couplings are preset in the factory to a customer specified disengagement torque and can be adjusted in the field after installation.
These unique torque limiting couplings are manufactured with a stainless steel bellow exhibiting very high torsional rigidity with zero backlash. An important feature of this design is the fact that the bellow can compensate for axial, angular, and lateral misalignment simultaneously.
The moment of inertia is also very low due to its low mass and low weight.
The SK2 safety couplings are available for a torque range of 0.2 to
500 Nm (1.8 to 4,425 in. lbs.). Both shaft hubs are custom
bored for shaft sizes of 4 to 60 mm (0.16 to 2.36 in.).
