TORSIONAL COUPLINGS MODEL 6 & 6B FLOATING SHAFT COUPLINGS 20 LF Torsional Model 6 & 6B Floating Shaft Couplings Model 6, 6/S (Rubber Elements) This model compensates for considerable axial, radial and angular misalignment. With the rubber flexible elements it is torsionally very soft. Lengths are not standardised but made according to customer requirements. S-style axial mounting screws allow the hubs to have free end float without exerting axial loads on the connected equipment while providing quick assembly. Model 6, 6/S (Zytel® Elements) Elements made of super tough, corrosion resistant Zytel ® from DuPont™ are torsionally stiff without backlash with less than 1° windup. Large spans, equal to all-metal couplings, can be accommodated without internal support bearings when lightweight Zytel® flexible elements are used. Hubs, hardware and tubes are also available in stainless steel or with plating and corrosion resistant coatings. S-style, axial mounting screws al low for free end-float without harmful react ion forces. Model 6B (Rubber Elements) Similar to Model 6 except the centre shaft is supported by internal maintenance-free bearing material. This allows for greater equipment seperation and high speeds. The Model 3, 6/S Rubber drawing illustrates one of the many special designs available. In this case a standard flywheel adaptor plate (see Model 3) is used to couple to a diesel engine flywhee l . The flanged hub on the other end is supplied with extra long Sstyle connecting screws. Note that the element is reversed from it’s normal direction. This arrangement permits extensive axial movement and free end float, of the drive package. One of the many features of the Model 6 is that the centre floating shaft can be radially removed without displacing the coupled machines. Flexible elements may be pre-assembled to the centre segment and then final assembled to the hubs quickly without any special tools.
