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 couplingmodel available for your application. www.jbj.co.uk/torque-limiting-couplings.html 22 #DriveLineHarmony Torque Limiting Couplings LF Torsional Coupling Supplement Model 0 and 0/S The heart of the DELFLEX 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 O/S permits the driver and driven equipment to be quickly "blind" assembled and allows for free end float. Available in various materials: High-Temperature, Rubber (HTR), Neoprene (CR) and durometers: 50, 60, 70, and 75 ShoreA. Model 1 and 1/S Consists of the standard flexible element (Model 0) with a simple steel cylindrical hub. This satisfies the application requirements for mounting directly to engine flywheels, pulleys, brake discs, friction clutches, universal joints and gears. The cylindrical hub is available in a range of bores (StandardANSI, DIN, JIS) inch, metric, spline 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 theModel 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 tomake the shaft to shaft connection. 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 accomplished without harmful push-pull force. Parallel misalignment Torsional misalignment Angular misalignment Axial misalignment » Free end float (Type S) » Substantial shock, vibration, andmisalignment capabilities. » Fail-safe operation. » Coupling allows "blind" connection of equipment. » High-speed capabilities. » Economic design. » Application versatility. » Lowweight, lowmoment of inertia. » Free fromnoise and electrically insulating. » No lubrication, maintenance free. » Oil, heat, and corrosion resistant elements (Hytrel®, Zytel® on request). » Easy to disconnect driver and driven without moving equipment or coupling hubs. » Unique "air flow" design assists in keeping components cool during operation. » Short profile for tight engine housing, or shaft-to-shaft requirements. » Easily assembled, no special bands, tools or time consuming assembly procedures. » Torque transmission does not exert harmful reaction loads on equipment. » Various element materials for variation in torsional stiffness and environmental resistance on demand.
