If torque and revolution per minute are known horsepower transferred can be calculated as. P hp = T n / 5252 (4) where . P hp = power (hp) T = torque (ft lb f) n = revolutions per minute (rpm) Speed Ratio. Speed ratio can be calculated as . SR = n f / n s (5) where . SR = speed ratio
Load torque calculation for rotary index tables uses the same formulas as a belt drive, but it requires a slightly different thought process to determine the necessary this case, friction occurs at points where the ball rollers (support bearings) and the table make contact, so radius (r) will be the distance from the center of the motor shaft to the contact point between the table ...
Belt conveyor _2. 5. Continuous weighing device for constantly measuring the load being carried by the conveyor How material is to be discharged from the belt overhead pulley or by trippers, and particulars ofA set of three rollers are arranged to form a trough for the troughed belt conveyor.
HP E = Empty Horsepower Requirement Wc = Weight per foot of Chain and Flight (Lb/ft) L = Length of the Conveyor (ft) S = Speed of the Chain (ft/min) Fc = Friction Factor of the Flights on the Bottom Housing. Note: Frictional factor used in the above formula vary depending on the specific appliions and products being conveyed. Testing may be required to determine the exact values to be used.
