Torsion couplings for mobile hydraulics

R+L Hydraulics GmbH now also produces LK series torsion couplings in Werdohl in the Sauerland region. The drive technology and hydraulics specialist are a subsidiary of the US clutch manufacturer Lovejoy LLC, which has further expanded its European site with production in Germany. The torsion clutches in the LK series are ideal for use in mobile hydraulics: they are used in diesel, petrol or natural gas engines that drive one or more flange-mounted hydraulic pumps. Typical applications include excavators, vibratory rollers, loaders, cranes, passenger elevators, forklifts and tractors. The LK torsion coupling is a stable, two-part coupling consisting of an element or a flywheel adapter and a hub for shaft connection. The couplings are very torsional stiff and enable hydraulic pumps and similar units with low mass or inertia to be operated below the critical speed. They can be used in all motor-driven hydrostatic applications in the low to medium power range. LK torsion couplings are maintenance-free and are characterized by their low weight, high torsional stiffness, and long service life. Their performance spectrum covers the range from 125 to 6,000 Nm. The hubs can be modified in shape and length, and different flange positions are possible. Various series for standardized SAE flywheels and non-standardized flywheels are available. R+L Hydraulics offers application support and on-site assessment for the respective applications. www.rl-hydraulics.com.
