Jaw coupling SC series

flange

Advantages: High torque capabilities Different material choices for the spider allow the user to choose torsional stiffness Somewhat “fail-safe”, in the sense that the driving hub will continue to turn the driven hub after failure of the spider Easy installation in blind or difficult installations – all jaw couplings have through bores Dampens variations or spikes in torque, usually caused by the driving element, protecting the support bearings and the driven component, and reducing vibration Wear element can be reversed before being replaced, doubling life Rugged, can function well in harsh environments Replaceable, inexpensive wear element Disavantages: Relatively high reactive forces exerted on support bearings, proportional to misalignment Even preloaded, so-called “zero backlash” jaw couplings have considerable wind-up, which is essentially the same as backlash, and disqualifies jaw couplings from servo applications Accommodates relatively small misalignments, considering large size of couplings Typical Applications: Pumps, particularly gear, lobe, vane, and reciprocating pumps; also applications involving piston motors, or any system with high torque and vibration, where relative angular location of the two shafts need not remain constant. High-temp spider option good for down-hole directional drilling applications.
