LORD engineers can assist you with selecting an appro- priate coupling type and confi guration. With extensive analytical capability and years of experience in designing products for powertrain vibration, shock and motion control, LORD engineers offer everything from simple application assistance to complex system analysis and specialized product design.

Torsional vibration, transient shock and misalignment load analyses require specialized computer programs and engineering experience. LORD engineers can analyze your system and recommend the right solution, whether it’s a selection from the standard product line or a custom design.

LORD Corporation’s standard product lines of elasto- meric fl exible powertrain couplings are presented in the following sections. Many variations of standard products are available, but not listed as ‘standard.’ Main drive, fan drive, PTO and accessory drive couplings are available in a host of custom designs and variations of standard products. LORD engineers are ready to help you meet your specifi c application requirements with custom designs where necessary.

Product Lines

LORD offers fi ve major lines of elastomeric fl exible couplings. Standard lines are presented on the following pages. In addition to the standards listed, many variations are available in each product line.

Dynaflex® Shear-Type Couplings

LORD Dynafl ex Shear-Type Coupling features a durable elastomeric fl exing element bonded between two hubs. These couplings are designed for fractional horsepower applications requiring smooth starting transition, torsional vibration isolation and misalignment accommodation. Typical applications are small electric motor drives, low-torque mechanisms, power take-offs and auxiliary equipment drives.

Dynaflex® Spool-Type Couplings

LORD Dynafl ex Spool-Type Couplings can be arranged in a variety of confi gurations to create a wide range

of torque-transmitting capability. Elastomeric spool elements can be purchased in lot sizes for customer- assembled coupling designs, or LORD can provide a complete coupling assembly to meet specifi c application requirements. Typical applications are large drives requiring high torque capacity and low torsional stiffness.

Dynaflex® Bushing-Type Couplings

LORD Dynafl ex Bushing-Type Couplings are bonded elastomeric elements designed for use in multiple element coupling confi gurations where high torque capacity is required. Bushings are available in a variety of stiffnesses. They can be purchased in lots for customer-assembled designs, or LORD can provide complete coupling assemblies designed to meet your specifi c application requirements. Applications requiring high torque/high torsional stiffness, but angular, axial and parallel misalignment accommodation can be designed using these bushings in a variety of confi gurations including parallel and series arrangements.

Dynaflex® LCR Series Couplings

LORD Dynafl ex LCR Series Couplings features an elastomeric ring with bonded, bush-type inserts allowing various attachment confi gurations. These couplings offer a soft torsional spring rate which permits smooth transmission of driving torque while attenuating

shock torques and providing excellent misalignment accommodation. These couplings are used in PTO drives where torsion and cocking fl exibility are required. They can be mated with a variety of hub confi gurations. Special high-torque designs are available, as well

as custom designs to meet special application requirements.

Dynaflex® LCD Series Couplings

LORD Dynafl ex LCD Series Couplings are the ultimate coupling for reciprocating engine drives. This coupling features a bonded elastomeric fl exing element which is radially precompressed into a fl anged outer housing.

This design produces a low torsional stiffness for maximum isolation of engine fi ring-pulse-induced torsional disturbances, torque overload slip protection, misalignment accommodation, superior shock pulse attenuation and fatigue life, and is adaptable to a variety of drive attachment designs. Custom designs are available to fi t nearly every SAE fl ywheel confi guration available from most engine manufacturers.
