Jun 29, 2016· Take the stated motor rpm (or measured) and simply apply the appropriate ratio to the diameter of the motor pulley to get the speed you want. To make this easier: Motor rpm = 2000 rpm Motor drive pulley dia. = 2" (just for sake of argument) 2000 rpm, use a 2" driven pulley (1/1) 1000 rpm, use a 4" driven pulley (1/2)

ERPM (7 pole pairs) 30.88 mph - 49.69 km/h. 26.25 mph - 42.24 km/h.

The result will be the pulley and belt ratio. For example: a 2-inch drive pulley and a 4-inch load pulley yields a pulley and belt ratio of 1/2. This means that for every 1 turn of the drive pulley, the load pulley will make 1/2 of a full turn. The speed of the pulley …

Jun 27, 2019· Your current ratio is 3.5/9 = .388 so any combination of pulleys that provides that ratio will maintain the speed. If you use an 8″ pulley on the fan than a 3″ pulley on the motor will be close. 3/8 = .375 ratio. If the motor is 1800 rpm your current fan speed is 1800(.388) = 698 rpm. A 3″ to 8″ pulley would give you 1800(.375) = 675

The pulley ratio depends on the size of the two pulleys. Since the drive pulley is 2 inches and the driven pulley is 4 inches, the pulley ratio is 4 divided by 2, which equals 2. This means that the drive pulley has to turn two times to turn the driven pulley once. ... Calculate the belt velocity by multiplying the circumference of the pulley ...

On a ground driven planter unit, the drive wheel is 125 cm in circumference and turns a 13-tooth sprocket, driving a chain up to a 20-tooth sprocket. The 20-tooth sprocket is connected to a shaft which turns a 17-tooth sprocket that is connected to a 28-tooth sprocket which in turn spins the 45-cell planter plate.

The article discusses three popular systems of pulleys and discretely explains the involved operational mechanisms. The systems basically include different groups of pulley/string mechanisms, each involving a specific pattern of movement for lifting the attached weight in response to the applied effort. All the systems basically are designed with one common focus …

Belt lengths, Pulley sizes, Drive ratios Unlike a chain, a belt cannot be easily extended or shortened to accomodate different pulley sizes. Therefore, it is important to make a good choice in pulley sizes and belt length to obtain a desired drive ratio while maintaining a proper center to center distance between the pulleys.

The following timing belt pulley Pitch Diameter (P.D.) and timing belt pulley Outside Diameter (O.D.) charts allow the end user to quickly determine the dimensional requirements for a timing belt drive system. These charts allow the user to check for interferences before a system is designed for a given ratio.

Calculate the pulley ratio by dividing the pulley's pitch diameter by the pitch diameter of the drive pulley. For example, suppose the drive-shaft has a diameter of 2.2 inches, and two pulleys driven by the belt have diameters of 4.4 inches and 2.8 inches. The first ratio = 4.4/2.2 = 2, and the second ratio = 2.8/2.2 = 1.27.
