Disc Couplings For Accurate Systems
29 October 2012
For highly accurate systems found in industries such as test and measurement, medical, semiconductor, solar, and liquid handling, Ruland offers both single and double disc style couplings. Disc couplings have low inertia and are torsionally stiff making them suitable for precise zero-backlash systems with speeds up to 10,000rpm.
Disc couplings are comprised of two black anodized aluminium hubs and multiple flat stainless steel disc springs. Single disc styles are suitable for systems where compact installation is required. Double disc styles add a centre spacer to increase the misalignment capabilities. The centre spacer is available in a choice of anodized aluminium or insulating acetal for electrical isolation.
The thin disc springs allow for a substantial amount of misalignment between shafts, while remaining rigid under torque loads. Parallel misalignment is accommodated by the double disc style or by two single disc couplings used in tandem.
Ruland single and double disc couplings are available in both clamp style and set screw style with bore sizes ranging from 3 to 30mm.
