Phone / Fax / Visit / COUPLINGS election ProcedureTABLE 1 Torque and Horsepower RatingsSTANDARD SELECTION METHODThe standard selection method can be used for most motor,turbine, or engine driven applications. The following informationis required to select a gear or torqueRunning or type of equipment to be connectedpump, drive to conveyor, etc.).Shaft space limitationsSpecial bore or finish information and type of fit:Determine system torque. If torque is not given,calculate as shown Torque (lb - in) = HP x 63,000 RPMW here: HP (Horsepower) is the actual or transmitted powerrequired by the application (if unknown, use the motor or turbinenameplate rating) and RPM is the actual speed the COUPLING isrotating.

2 :Determine the appropriate service factor from Tables 3 on N-3:Determine the required minimum COUPLING rating as shownbelow:Minimum COUPLING Rating = x Torque(lb-in):Refer to N-4 To N-7 and select the appropriate COUPLING type.::Check bore, speed, Dimensions and Torque rating of shaft diameters against COUPLING maximum bore. If bore isinadequate, consider the use of a reduced key from engineeringtables, or select a larger size COUPLING .)Check the operating rpm against the COUPLING allowable speed. Ifcatalogued values are inadequate, consider may allow up to 50% increase in speeds are: length of hubs and alignment clearances againstshaft lengths, outside diameter of COUPLING against radialclearances1.

SIZECHECKS elect a gear COUPLING to connect a 500 HP, 1170 RPM electric motorto a drive high speed shaft of a maneuvering winch. Maximum shaftseparation is .250". Motor shaft diameter is " and keyway " x .438". Winch shaft diameter is " and keyway is 50" ". Motor and winch extensions are both " Torque (lb in)) ==26,9231170 rpm:From Table-3, N-3 x 26,923 lb-in = 40,385 x 500hp=750hp:From N-4 & N-5 to connect close coupled shafts (.)

Maximum bore capacity " exceeds the actual shaft diameters and torque rating of66, 150 lb-in exceeding the required minimum COUPLING rating of40,385.
