Rimtec's HSV permanent-magnet hysteresis clutches provide exceptionally smooth torque transmission with servo-quality overload protection for high-production bottle-capping applications
Even while transmitting high torque, the couplings are torsionally stiff, thus minimizing or eliminating wind-up and backlash.
The coupling's low inertia helps optimize servo-loop gains, thus maximizing the accuracy of servo master-slave operations throughout the entire press.
The Rimtec line of metal bellows couplings are available in shaft sizes from 0.04 to 3.35 inches (1 to 85 mm), with torque capacities up to 44,000 in-lb (5000 Nm).
Collet-type clamps ensure zero-backlash for the highest accuracy.
The company also offers servo-insert couplings, which provide the zero-backlash benefits of metal bellows couplings with added dampening characteristics where resonance is a problem.
The 3-part configuration adapts to the tight space requirements in some printing stations.
This line accommodates bore sizes from 0.08 to 4 inches (2 to 100 mm).
The Rimtec Corporation offers a broad line of precision servo couplings to dramatically diminish downtime and production costs for shaftless printing presses and many other demanding types of manufacturing production.
