CLAAS Industrietechnik GmbH, based in Paderborn, Germany is part of the CLAAS Group that focuses on drive technology including gearboxes and hydraulics. 
CLAAS Industrietechnik needed a coupling solution for use in the transmission for its newest range of ARION 500/600 series tractors. Having identified a contamination issue caused by the ‘as-machined’ delivery condition of many manufacturers’ standard couplings, CLAAS approached Huco for a specialized solution which would perform reliably.
The function of the coupling is to transmit rotation from the electric positioning motor to the hydrostatic module within the power-split transmission. The coupling has to provide elastic transfer of the forces and, because it’s operating in a hydraulic system, it needed to be contaminant-free.
Engineers at Huco Dynatork were immediately able to recommend its multi-beam couplings to perform as required within the gearbox. The coupling’s helical-cut design provides a higher torque capability and reduced backlash when compared to single beam couplings and will readily accommodate axial motion and angular & parallel misalignment.
Huco was able to offer its stainless steel multi-beam coupling complete with a full deburring and cleaning service. As a result, there were no issues with swarf or metal chips contaminating the hydraulic system.
