DYNAFLEX ELASTOMERIC FLEXIBLE COUPLINGS
Dynafl ex
®
LCR Series Couplings
Rated: 4 to 135 hp at 2000 rpm
LORD Dynafl ex LCR Series Couplings are ring-type
couplings developed to overcome numerous torsional
problems associated with vehicular and industrial drive-
line systems. These easily installed couplings reduce
noise transmission and increase bearing and driveline
life through greater misalignment accommodation,
isolation of low frequency disturbances, and isolation of
torsional shock.
These highly fl exible elastomeric couplings for acces-
sory drives are also designed to eliminate lubrication and
maintenance.
Features and Benefi ts
• Misalignment accommodation – elastomeric fl exibility
allows for large angular misalignment. For permissible
misalignments, including axial and radial, Refer to
Table 1.
• Vibration isolation – low torsional spring rate is
achieved with the elastomeric ring-type coupling
using rubber in compression. This allows for low
system natural frequencies and isolation of fi rst mode
driveline disturbances in most driveline systems.
• Shock protection – isolates torsional shock, prevents
backlash and protects system components, including
bearings, from fatigue failure.
• Long service life – Dynafl ex LCR Series Couplings
have proven themselves under demanding service
conditions.
• Maintenance-free – elastomer fl exibility accommo-
dates all motion without wear, eliminates the need for
lubrication.
• Noise reduction – no metal-to-metal contact; elas-
tomer attenuates structure-borne noise and isolates
vibration from components that would act as noise
generators.
• Systems Engineering – LORD has in-house computer
capabilities for multi-torsional analysis to assist in
proper coupling selection.
