For example, let's say you have a sprocket with 20 teeth and the pitch of the chain is 0.5 inches. Using the formula above, we can calculate the pitch diameter as follows: Pitch Diameter = (20 / 0.5) x 25.4 Pitch Diameter = 508 mm. Therefore, the pitch diameter of this sprocket is 508 mm.
two results, both lead to shortened belt life. Rolling causes low belt tension resulting in low belt life due to slip and heat build up. Prying a belt damages cables in the belt, leading to early belt failure. Belt life varies greatly depending on not only how the belt is installed, but on how the belt is tensioned at installation.
The simplest way to find the ratio of the required pulley is to divide the driven component (pump) by RPM. For example, if the pump RPM is 1070 for full output, while the motor is 1750 RPM, the ratio of the required pulley would be (pump RPM) divided by the motor RPM, or: 1070 / 1750 = 0.611. Going by our above example, your pulley ratio must
Assuming that the pulleys have diameters of 6 and 20 inches, you need a belt that's exactly 153.72 inches. To find that number on your own, you need to use the belt length formula: Belt length = π/2 × (D L + D S) + 2L + (D L - D S) 2 /(4L), where: D L is the diameter of the larger pulley (here 20 inches);
Your timing belt should be replaced every 50,000–70,000 miles, depending on your car's make and model. Also, make sure you understand if your engine is an interference engine or a non-interference engine. In an interference engine, the valves and piston share the same airspace and the timing belt keeps them from touching.

Once the pitch diameter is calculated, the pulley’s outer diameter can be determined by finding the distance from the belt pitch line to the bottom of the tooth profile (a value specified by the belt manufacturer), and subtracting twice that distance from the pulley pitch diameter. O.D. = pulley outer diameter (mm, in)
Pulley and Belt Length Calculator. In this calculator, there are three main sections dealing with pulleys, belts and speed. In each section, only one variable is calculated, based on the checkbox. In the first, the driver pulley is the powered (usually by an electric motor) pulley. The driven pulley is the reactive pulley to the driver.
HabaSYNC® timing belts are made up of several key component parts. Each must complement the other precisely in order to provide a highly effective synchronous drive solution. Geometry-related nomenclature: Teeth The teeth on a timing belt are responsible for the intermeshing action that occurs when a timing belt and pulley are engaged.

To explain the experimentally observed trends, the authors relied on a Childs experimental–theoretical study on contact and on friction between a flat belt and a pulley [22]. The relationships between the shear stress and the friction coefficient with the pressure are: (22) τ = B p n μ = B p n − 1. The constant B in Eq.
