* Service factors listed are to be used as a general guide. For each degree of angular misalignment add .1 to the service factor up to 3°. Should any questions arise concerning specific
application, contact Application Engineering at 800-626-2093, or e-mail: ApplicationEngineering.PTSolutions@emerson.com.
** For application in which power source is an internal combustion engine, and for compressors without flywheels, add 0.75 to service factor.
Selecting an EVER-FLEX Coupling
A. Multiply the power supply rating by the appropriate
Service Factor from Table No. 1, above, to get the
“Normal Rating”.
B. From Table No. 2, page 91, select a coupling which
will deliver the “Normal Rating” or more at the proper
speed.
C. Check Tables No. 1 and 2, page 90 to make sure
the coupling has a bore range to fit both driver and
driven shaft.
Example
A coupling is required for a 1800 RPM, 10 HP motor
driving a rotary oil pump. Motor shaft is 1 3/8" and the
pump shaft is 1 1/4".
A. Multiply motor rating (10) by the service factor for
a rotary pump (1.5), see Table No. 1, above.
10 x 1.5 = 15.0
B. From Table No. 2, page 91, note that a CFR5
coupling will deliver 19.77 HP at 1800 RPM which
is greater than the 15.0 HP which is required.
C. From Tables 1 and 2, page 90, note that a CFR5H
uses and “H” bushing which has a bore range of
3/8" to 1 1/2". A CHFR5H is the correct coupling for
this application.
Adaptability Suggestions
SPACER MOUNTING
(Spacers must be provided by customer)
HUB MOUNTING
EVER-FLEX ® Couplings provide versatile mounting possibilities. Stock halves
can be mounted with spacers or one half can be mounted to customer’s hub,
flange, sheave, sprocket, gear or other drive member for flexibility. When
hub mounting is used, the half coupling will provide approximately half the
misalignment compensation as a complete coupling.
