Pulleys in power transmission achieve mechanical advantage when the drive pulley has a different diameter than the driven pulley. In other words, Pulleys that are moving energy from one place to another can change the speed and strength by being different sizes. In a basic two-pulley system there are three possible options: The drive pulley and ...

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.

Increase efficiency, vary speed, and extend the life of your drive by changing the pitch on these pulleys. Adjustable-Speed V-Belt Pulleys Also known as step-cone pulleys, these have multiple groove sizes so you can quickly change rotation speed by moving your belt to a different groove.


Outside diameter, or the distance across the pulley when measured between groove edges. Center diameter is the distance or distances between the shafts of the pulleys in the transmission. V-belt transmissions are limited by center distances, which must be no more than three-times the diameter of the largest pulley, lest significant slipping can ...

Conveyor Pulleys - Bosworth

2.0 Pulley design. There are various factors influencing the pulley diameter. The pulley diameter is mainly determined by the conveyor belt class, but the required shaft diameter also influences the diameter. A golden rule for the pulleys diameter is that it should be at least three times the diameter of the shaft. 2.1 Pulley Types

If the drive pulley on the engine is 4 inches in diameter, we need to calculate 4/.315 = 12.70. This means that the pump pulley must be 12.70 inches, in diameter, to run the pump at 1070 rpm. You can view a technical page from our catalog here – it will help to further explain the calculation process. Tapered Bushing vs. Fixed Shaft Bores

The pulley is required to be capable of 20 years operation, at full load, 300 rpm, 2 shifts per day. B Exectutive Summary (to be finalised) Fatigue requiremenst on the shaft alone would permit the use of steel shaft of a minimum 100 Dia to be used. The deflection requirements at the keys dicate a larger shaft diameter of 130 mm Dia.

When designing a belt drive system, the first step is to choose the most suitable belt for the application. But the pulleys also play an important role in the performance of the belt — especially in synchronous belt drive systems, where proper meshing of the belt teeth with the pulley grooves can affect everything from the amount of torque that can be transmitted to the belt's rate of wear ...

In Standard Handbook of Petroleum and Natural Gas Engineering (Third Edition), 2016. 3.2.1.3.7 Creep and Slip. As a belt turns on a pulley, it tends to stretch on the contact arc of the driving pulley and shorten on the driven pulley.This local movement of the belt is known as creep.The loss in speed is about 0.5% and is neglected in sizing and speed calculations.


Tensioning pulley diameter must be equal to that of the smaller pulley of the drive. 6. If tension pulley of flat type is to be used then it should be placed on the outside of the belt and at one third of centre distance from the driving pulley.


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)


Minimum Pulley Diameters: How small is too small. As technology advances and systems get smaller and smaller so too does the desire for smaller drive pulleys. Though size can be decreased, it is important to ensure that none of the drive pulleys fall below the minimum recommended diameters given this can result in shortened belt life, premature ...
