Sprocket Ratio Calculations Sciencing
The easiest way to calculate sprocket ratio is to count the number of teeth on both the driving and the driven sprockets and divide the first by the second. This ratio tells you how many times the driven sprocket turns for every revolution of the driving sprocket. From this, you can calculate revolutions per minute (rpm) for the driven sprocket.Typical Conveyor Capacity. 1 in = 25.4 mm. 1 ft3/h = 0.028 m3/h. 1 ft/min = 5.08 x 10-3 m/s.

How to Find Belt and Pulley Speeds Sciencing
Pulley speeds depend on what is driving the pulley and the size of the pulley and the pulley it is connected to. When two pulleys are connected through a belt, the velocity of the belt for both pulleys is the The decisive factor for the transmission of power in belt drives is the circumferential force (also called effective force), which results from the difference between the tight side force and the slack side force of the belt! At the pulley with the diameter d o driven by the belt this effectively circumferential force F c leads to a changedPower transmission of a belt drive tec-science

Motor Sizing Basics Part 1: How to Calculate Load Torque
To calculate load torque, multiply the force (F) by the distance away from the rotational axis, which is the radius of the pulley (r) . If the mass of the load (blue box) is 20 Newtons, and the radius of the pulley is 5 cm away, then the required torque for the application is 20 N x 0.05 m = 1 Nm. Typically, a safety factor is used so that theThis pulley calculator analyzes a system of two pulleys joined by a conveyor belt (also called a belt drive).
