3 Model 0 and 0/S The heart of the LF Torsional coupling is the flexible element. This model is easily mounted to the customer ’s application designs or customer provided shaft hubs. No bands, special tools or contoured element clamping flanges are necessary. This model allows the customer to make his own shaft hubs from readily available steel bar stock. Ideal for quick prototype testing, retrofit and high volume applications. Model 0/S permits the driver and driven equipment to be quickly “blind” assembled and al lows for free end float. Available in High-Temperature Rubber (HTR) 50, 60, shore hardness as standard. Other materials and shore hardness grades are available for certain sizes. Model 1 and 1/S Consists of the standard flexible element (Model 0) with simple steel cylindrical hub. This satisfies the application requirements for mounting directly to engine flywheels, pul leys, brake discs, friction clutches, universal joints and gears. The cylindrical hub is available in a range of bores inch, metric, spline (SAE, ANSI , DIN, JIS) and custom. Model 1/S is shown with the S-style axial screw (similar to a dowel) for quick blind assembly of the drive package. The same element combinations available in Model 1 are also available in the Model 1/S. Model 2 and 2/S Provides a complete shaft-to-shaft coupling in a range of sizes for all industrial power transmission applications. It is similar to Model 1 shown above except a flanged hub is added to make the shaft to shaft connect ion. Model 2/S allows the drive package to be “blind” connected. As with all S-style models, free axial end float of equipment shafts is accompl ished without harmful axial force. Model 3 and 3/S A Model 1 or 1/S with the addition of an engine flywheel mounting plate, becomes a Model 3 or 3/S. It is available in many standard SAE flywheel sizes ( see page 18) as well as bespoke sizes. Special mounting requirements are easily and economically accomplished. The standard cylindrical hub is available in a variety of SAE, ANSI , DIN and JIS spilne bores as well as straight bores. As with the previous models, various standard flexible element materials are available for specific torsional, misalignment and environmental requirements. TORSIONAL COUPLINGS LF TORSIONAL COUPLING SYSTEM LF Torsional Coupling System These are the six standard LF Torsional coupling models. The simple, unique design of the LF Torsional coupling permits this wide range of models, from common components, to meet each application requirement. From engine flywheel housing or the long corrosive span of a cooling tower, we have the optimum LF Torsional coupling model available for your application. #DriveLineHarmony www.jbj.co.uk/torsional-couplings.html
