The Speed Ratio is the ratio of angular velocity of the input pulley of a system to the angular velocity of the output pulley. If you've calculated gear ratios, it is almost exactly the same! This is all based on a pulley's reference diameter, as defined below: Reference/Pitch Diameter: The working diameter of the pulley, where the belt or cable contacts the pulley
V-Belt Pulleys. 931 products. V-belt pulleys are for use with V-belts to transfer motion from motors to belts, fans, and pumps. They have V-shaped grooves that correspond with V-shaped belts to prevent slippage and misalignment. V-belt pulleys provide maximum friction and torque in compatible V-belt drive systems. View More

Belt driven fans are used in heating, ventilation, air-conditioning and cooling (HVAC) systems. The speed of a fan wheel versus the speed of the motor with a belt drive can be calculated as. d f n f = d m n m (1) where. d f = pulley diameter fan (inch, mm) n f = speed of fan (rpm - rounds per minute) d m = pulley diameter motor (inch, mm)

Axial fans, as the name implies, move an airstream along the axis of the fan. The air is pressurized by the aerodynamic lift generated by the fan blades, much like a propeller and an airplane wing. Although they can sometimes be used interchange-ably with centrifugal fans, axial fans are commonly used in “clean air,” low-pressure, high-volume

A ratio of 2 to 1 would be signified by 2:1. A ratio of 1/4 to one would be signified by .25:1. To find the total ratio, use the pulley ratio formula: Ratio = (Radius of Driven Pulley) / (Radius of Drive Pulley) Example: A handcrank is attached to a drive pulley of 2 inches in radius. The belt runs from the drive pulley to a driven pulley. The driven pulley is 6 inches in radius and is attached to a paddle that
