Details


    The complete LF Series Model 2 is comprised of a cylindrical hub, a flanged hub, a base element, and hardware.The Model 2 provides a complete shaft-to-shaft coupling in a range of sizes for all industrial power transmission applications. It is similar to Model 1, except a flanged hub is added to make the shaft to shaft connection.Model 2/S allows the drive package to be “blind” connected. As with all S-Style models, axial end float of equipment shafts can be accommodated without harmful push-pull force.

Torsional Element Specifications
    There are two different rubber element materials available, High Temperature Rubber (HTR) and Neoprene (CR). Both elements are torsionally soft and are placed into compression during assembly. Rubber under compression can carry up to 5 times the amount of torque as non-compressed elements. The elements effectively accommodate shock, misalignment, and vibration plus minimize harmful radial and axial forces on the connected equipment. Neoprene (CR) is used in environments that are hostile to High Temperature Rubber (HTR).
    Available Durometer Hardness:
  • 50, 60 (Shore A scale)
    Operating Temperature Range:
  • HTR: -40 to 194 F
  • CR: -40 to 175 F
    Maximum Angular Misalignment:
  • Up to 3


Features
  • Wide range of standard designs and materials
  • Application versatility
  • Shaft to shaft or flywheel to shaft designs
  • Designed to accommodate substantial shock loads, vibration, and misalignment
  • Low moment of inertia
  • Electrically insulating
  • No lubrication, maintenance free
  • Unique air-flow cooling design
  • Different element stiffness values allow for torsional tuning of applications with diesel engines
  • Economic design allows for cost effective solutions for torsional applications
  • Proven L-LOC spline-clamping hub virtually eliminates spline shaft profile wear and fretting
  • Oil, heat, and corrosion resistant elements (Hytrel, Zytel)
  • When used with S-bolts, the coupling can accommodate some end float
  • S-bolts accommodate applications requiring blind assembly
  • Model 6 unique spacer designs span gaps between equipment in excess of the normal equipment separation
  • Model 6 design available with bearings for high speeds and large amounts of equipment separation


Notes
  • For Hytrel, dynamic torsional stiffness values are non-linear with respect to torque. Value given is for 100% of nominal torque.
  • Angular and parallel misalignment values are dependent on speed, and for rubber elements, should be adjusted according to figure 4. Hytrel elements are only for applications where the driven component is piloted to the driver for SAE and DIN established alignments (i.e. Hydraulic pump flange-mounted to engine flywheel housing).
  • Hytrel elements are only for applications where the driven component is piloted to the driver for essentially perfect alignment (hydraulic pump flange-mounted to engine housing).


Model Specifications
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 connection.Model 2/S allows the drive package to be blind connected. As with all S-Style models, axial end float of equipment shafts can be accommodated without harmful push-pull force.
