Horsepower Horsepower equals 33,000 foot-pounds per minute, or 550 foot-pounds per second. In terms of chain working load or pull (P) <strong>and</strong> speed: P x S HP = 33,000 P x Number of Teeth x Pitch x RPM HP = 396,000 HP = HP = Ratio Torque (lb.-in.) x RPM 63,025 Torque (lb.-in.) x RPM 5,252 Teeth in Large Sprocket Fast RPM Ratio = or Teeth in Small Sprocket Slow RPM Chain Working Load When horsepower input is known, calculate for chain working load or pull (P): HP x 33,000 P = FPM HP x 396,000 P = Number of Teeth x Pitch x RPM Torque P = Sprocket Pitch Radius Chain Speed Speed (FPM) = Pitch x Number of Teeth x RPM 12 Sprocket Speed Engineering Information RPM of Driven Sprocket = Roller Chain Formulas 12 x RPM RPM = Number of Teeth x Pitch Driver Teeth x Driver RPM Driven Teeth Driven Teeth x Driven RPM RPM of Driver Sprocket = Driver Teeth Centrifugal Pull or Tension Pull or tension caused by chain weight <strong>and</strong> velocity: Centrifugal Pull = Total Chain Tension Torque Factory of Safety Chain Ultimate Strength Chain Working Load P-1930-BG 04/10 Boston Gear 800-825-6544 249 FS= Chain Weight per Foot x (FPM) 2 115,900 Total Chain Tension = Working Load + Centrifugal Pull Chain Bearing Pressure Bearing Pressure Working Load (pounds per square inch) = Bushing Length x Pin Dia.
