The key feature that makes disc pack couplings different from other models is the parallel arrangement of multiple friction elements. They can be used under high loads and are popular with engineers for being both compact and cost-effective. Standard disc pack couplings often operate in oil and are generally used in automatic transmissions, high-load main and starting couplings, and limited slip differentials. The coupling specialist R+W Antriebselemente GmbH has now expanded its popular LP range of torsionally strong disc pack couplings and is showcasing a new model at HANNOVER MESSE 2017 alongside its existing products. The new coupling is available with integrated cooling lubrication and is thus set to be particularly useful to manufacturers of machine tools with long spindle setup.

Thanks to an integrated inner tube and adaption interfaces on both sides, the specially designed double Cardan spindle couplings can apply the cooling lubricant directly into the tool - even across a long distance. To withstand high and dynamic processing speeds, the couplings are fitted with weight-optimized CFRP or aluminum outer tubing. What's more, symmetrical conical clamping rings and special balancing mechanisms ensure minimum operating noise and excellent balance, while shaft misalignments are compensated for by the torsionally strong disc packs. As a result, this robust and powerful model helps users to simplify spindle setup, cut assembly times, increase processing speeds and extend service life.
