The LF Series coupling is designed with a unique and highly versatile elastomeric element. These can be easily integrated into a variety of coupling configurations to meet several application needs. LF Style elements are available in a variety of materials to match the necessary coupling dampening characteristics for tuning the systems critical speed away from the application operating speed.
The element can be connected axially to a flywheel adapter plate or flanged hub and radially to a cylindrical center hub using the appropriate bolts. Axial bolt styles include either socket head bolts with a special dry adhesive, or S-Style bolts, which are similar to dowel pins (seen picture below). The radial bolts are used to connect the element to the cylindrical hub. This unique design is remarkably simple, highly effective and gives the LF torsional coupling unmatched performance capabilities. The coupling selection should be verified with a Torsional Vibration Analysis (TVA) of the system.
The heart of the LF Series coupling is the flexible base element. This
element allows the customer to make their own shaft hubs from steel bar
stock or use existing hubs. Ideal for quick prototype testing, retrofit and high
volume applications.

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.
Spline shaft wear, profile distortion, and fretting corrosion all are major concerns in spline shaft applications such as hydraulic pumps. We are pleased to state that Lovejoy has a solution. It’s called the L-LOC.
It is common knowledge that typical manufacturing tolerances between spline shafts and mating coupling hubs create some unavoidable play or backlash. This backlash is defined as the minor movement between the shaft and hub, typically resulting in wear. This tolerance related movement and wear is often further compounded by misalignment and hammering forces common in power transmission. As a result, fretting wear and profile distortion can occur, even when shafts are manufactured with high quality hardened steel ...

A Model 1 or 1/S with the addition of an engine mounting plate
becomes a Model 3 or 3/S. It is available in standard SAE
flywheel sizes as well as made-to-order sizes. The standard
cylindrical hub is available in a variety of ANSI (SAE), DIN, JIS,
and agricultural spline bores for hydraulic pumps and other
applications. Various standard flexible element materials are
available for specific torsional, misalignment and environmental
requirements.
