Effi cient power transmission and driveline component durability are among powertrain designers’ most impor- tant concerns. Increased durability and up-time are two characteristics demanded by purchasers of today’s complex and expensive machinery. These demands can only be met with reliable, trouble-free, smooth-running powertrains free from damaging loads which compro- mise component life.

Powertrain component life is determined by the load spectrum each component will experience during the machine’s service life. Reciprocating engines, such as spark-ignited gasoline and compression-ignited diesels, produce alternating torque loads which, when super- imposed on the steady driving torque, create alter- nating stresses in driveline system components which shorten component life and reliability. High transient start-up torques and misalignment caused by skewed rotational axes between driver and driven in electric motor, hydraulic and pneumatic drives also cause high imposed forces on driven components. These unwanted forces loosen bolted joints and cause spline fretting, clutch disk wear, bearing failure, gear tooth fatigue and shaft fatigue, among an array of other problems.

Elastomeric fl exible couplings solve these problems. They prolong driveline component life because they reduce the magnitude of imposed loads, attenuate vibra- tion in multiple planes, accommodate misalignments

in multiple planes, and act as barriers impeding noise created by meshing gears, engaging clutches, etc.

Elastomeric fl exible couplings are also maintenance- free. They require no lubrication or other maintenance throughout their service life. Among the large variety of coupling types available, LORD Corporation’s elasto- meric couplings offer the most comprehensive package of benefi ts available to the powertrain designer. LORD Corporation’s product lines include fi ve different elas- tomeric coupling styles which cover a wide range of application requirements.

Application

Application requirements suggest the coupling style needed to optimize powertrain performance and component longevity. Misalignment accommodation, torsional vibration isolation, transient shock dissipation and required service life are important parameters

to consider when selecting a coupling to fi ll specifi c application requirements.
