Drum coupling TNK TKVO

torsionally rigidtransmissionshaft

Application and Performance Optimized Type Made of High-Strength Material for Rope Drums in Lifting Units of Cranes and Hoists Your Advantages The type RINGFEDER® TNK TKVO is a torsionally stiff barrel coupling with hub and housing made of high strength material. The inner ring integrated in the housing enables quick and easy assembly with an extremely compact coupling design. The type incorporates construction according to the operation sheet of the German Steel Iron Industry SEB 666212 for rope drum hinge joints. Barrel couplings of the RINGFEDER® TNK TKVO type are particularly convincing due to the following features: Torsionally rigid, compensate for angular and axial shaft misalignment Torque transmission by steel rollers With standardized connection to rope drums in crane lifting gear Reduced assembly effort due to integrated inner ring as well as simplified insertion of the barrel coupling With wear indicator for easier condition monitoring Bore diameter d1 up to 440 mm (17.323 inch) Outer diameter D up to 850 mm (33.465 inch)
