At high rotational speeds special considerations must be made for the design and manufacturing quality of a coupling, as any inaccuracies in machining and balancing become magnified as velocity increases. A high level of concentricity is crucial to ensure smooth and precise transmission of the rotary motion.
Couplings also need to be able to withstand high levels of torsional strain from acceleration and occasional shock loading in these applications. The compensating buffer and wear resistance of the elastomer are important to ensuring reliable performance of the complete system.
SP6 high speed coupling from R+W Antriebselemente GmbH is a state of the art, high performance solution for machining spindles and other high speed drive applications.
It is made from high strength aluminum or steel, along with thermally stable and wear resistant TPU elastomer, which makes it particularly resilient. The elastomer ring has a vibration damping effect while remaining backlash free, due to a precision preload between the coupling jaws. Two precisely manufactured hubs with clamping rings and concave jaws ensure the performance.
