Mechanical Power Transmission

APPLICATION FORMULAS

Horsepower = Torque x Speed

1 HP = 3 lb-ft @1750 rpm

1 HP = 36 lb-in. @ 1750 rpm

T (lb-ft) = [HP x 5250] / rpm

T (in-ft) = [HP x 63025] / rpm

HP = [Force (lb) x Velocity (ft/min.) ] / 33,000

Velocity (ft/min.) = .262 x Dia. (in.) x rpm

Torque (lb-in.) = Force (lb) x Radius (in.)

Output rpm = Input rpm / Ratio

OHL = [2 TK] / D

OHL = Overhung Load (lb)

T = Shaft Torque (lb-in.)

K = Overhung Load Factor

D = Pitch Diameter of Sprocket, Pinion or Pulley (in.)

Overhung Load Factors: Sprocket/Timing Belt = 1.00 Pinion & Gear Drive = 1.25 Pulley & V-Belt Drive = 1.50 Pulley+Flat Belt Drive = 2.50 Variable Pitch Pulley = 3.50
