Information on Synchronous Drive components such as: Timing Belts, Timing Pulleys, Sprockets, and Chains. Looking for a custom timing pulley? SHOP ONLINE (800) 819-8900. Menu. Products. Products. This calculator computes belt lengths for various center distances and checks the number of teeth in mesh for both pulleys. It calculates pulley

If your pulley type is not listed above enter the pitch below: Pulley / belt pitch selected Number of teeth on largest pulley Number of teeth on smaller or same size pulley Belt length mm inches No. Teeth Results in mm inches PCD (dp) of largest pulley PCD (dp) of smaller pulley Distance between centres v1.2 Get social My account

P= Pitch of Belt. (distance between teeth) Cb= circumference of belt. Db= Diameter of belt. Dpo= Outer Diameter of pulley. Dpi= Inner Diameter of pulley. Tb= Thickness of belt, measured from. When sizing to the motor (loading parameters at the drive pulley) you are required to calculate peak power and RPM, peak torque and RPM, peak peripheral force and RPM and reduction ratio.

Belt Length in a Pulley System. The length of the belt in a pulley system is directly dependent on the diameters of both pulleys (driver pulley and driven pulley) and the distance between their centers is denoted by ‘D’: L = (d₁ * π / 2) + (d₂ * π / 2) + 2D + ( (d₁ - d₂)² / 4D) The user can also reverse this formula to calculate

The speed ratio is defined as the ratio of the large to small pulley size and can be calculated simply by dividing the number of teeth in the 

Nov 17,  · 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

To use this online calculator for Torque Transmitted by Pulley, enter Tangential Force at End of Each Pulley Arm (P), Radius of Rim of Pulley (R) & Number of Arms in Pulley (N) and hit the calculate button. Here is how the Torque Transmitted by Pulley calculation can be explained with given input values -> 88800 = 300*0.148* (4/2).

Timing Belt Length Calculator. Step 1. Please enter distance between the centers of the pulleys and the diameters of both the pulleys, or if you know the length of the belt you require, simply enter the length below: Pulley Center Distance: mm.

Timing Pulley Generator This post describes the inception of, and my work on, the Timing Pulley Generator Tool. As I was working on a DIY clock project, I quickly became aware that I was going to need lots of timing pulleys. I had decided on the MXL standard to minimize the size of my project but quickly ran against a cost hurdle.

If you know any 3 values (Pulley sizes or RPM) and need to calculate the 4th, enter the 3 known values and hit Calculate to find the missing value. For example, if Pulley 1 is 80mm diameter, and spins at 1000 RPM, and you need to find the Pulley 2 size to spin it at 400 RPM, enter Pulley 1 = 80, Pulley 1 RPM = 1000, Pulley 2 RPM = 400, and hit

Aug 04,  · Let's learn how to calculate the length of a belt in a two-pulley system with differing diameters of pulleys. You can do it by inputting the distance between the axles of the pulleys and their diameters into the following formula: Belt length = ( (D L + D S) * π / 2) + (D L - D S) * arcsin ( (D L - D S) / 2L) + 2 * √ (L 2 − 0.25 * (D L - D S) 2)
