21/02/2005 · hi I am trying to buil a spreadsheet for calculation the required HP of roller conveyors The setup of the conveyor is te following: Motor connected to a gearbox

The speed at which a body moves is one of the most fundamental parameters within physics In terms of linear motion, speed is defined as the distance traveled divided by the time taken

Calculate speed by multiplying the circumference by the rpm Say the wheels are moving at 1,000rpm Speed = RPM * Circumference Speed = 1,000 revolutions/minute * 754 inches/revolution Speed = 75,400 inches/minute Note: The tyre's rpm is not necessarily the same as the rpm gauge in your car, since that's measuring engine rpm

21/02/2005 · hi I am trying to buil a spreadsheet for calculation the required HP of roller conveyors The setup of the conveyor is te following: Motor connected to a gearbox Output sprocket linked to a roller sprocket All rollers linked toghether This conveyor should move a pallet-load of X lbs, at Y feet/minutes The various speeds are reached by changing sprockets/gearbox, and the motor size needs to …

In terms of linear motion, speed is defined as the distance traveled divided by the time taken Bodies that rotate, such as wheels, use a different quantity to define rate of rotation This is often the number of revolutions carried out per minute It is straightforward to convert between revolutions per …
