Allowable Side Load Pulls:The following formula can be used to calculate applied sideload. Loads are calculated on proper tensioning of belts. Ifbelts are tightened excessively, the resulting side load canexceed these limitsStandard Power Take-Offswith7.5”HEClutchesL =126000 x H.P.N x Dx F x AL = Actual Applied Load (lbs.)N = Shaft Speed (rev./min.)D = Pitch Diameter of Sheaves, etc. (in.)F = Load Factor (see below)1.0 for chain2.5 for V belt drive3.5 for flat belt driveA = 1.0 for low & moderate duty drives1.4 for severe duty shock loads or largeinertia loads (reciprocating compressors,crusher, chippers, planers, etc.)Required Clutch Torque Capacity Calculation:Required Clutch Torque = Maximum Engine Torque x Service FactorPower Take-OffPart NumbersRPM1600190022002500280031000904854813779750725411238AM1, 411238AM, 411298AM,414200AM, 414565AM, 434193AM1”804459723693667645X“ Distance2”7246836516246015813”658621592567546528Blower or Vacuum• Centrifugal with free flow of air................ 1.7• With high start-up inertia orsubject to choking of air supply ............... 4.0Compressors• Reciprocating, 1 or 2 cylinders ................. 4.0• Reciprocating, 3 or more cylinders........... 2.5• Roto screw or turbine ............................... 2.0Conveyor• Fed uniformly ........................................... 1.5• Not fed uniformly ..................................... 2.0• Recriprocating .......................................... 3.0Drills ................................................................ 2.0Generator ........................................................ 2.0Pump• Centrifugal or turbine ............................... 1.5• Dredge ..................................................... 2.0• Mud or reciprocating ................................ 3.0Rock Crusher, Hammer Mill ........................ 3.0Snow Blower ................................................. 2.0Wood Chipper, Saw Mill ............................... 3.0Ratings: Shafts, bearings and clutch capacities are rated on a conservative basis.
