Calculate the length of your timing belt with B&B Manufacturing's belt length calculator. Stock and custom belts available.

Click CALCULATE and the Pulley Ratio will show you "0.5 to 1", meaning your Pulley 2 will be turning at half the speed of Pulley 1. The Belt Length dropdown will show a 74 Tooth belt with 1.4mm of slack. Coincides with the circle made by the reinforcing cord of the timing belt. Pulley Ratio: (Pulley 1 Pitch Diameter / Pulley 2 Pitch

Well there is an equation and an online calculator for that too. CALCULATE DISTANCE BETWEEN PULLEYS. Length of Belt. Diameter of the Large Pulley 

We can form the following definitions and equations: N= Number of teeth on pulley. Cb= circumference of belt. Db= Diameter of belt. Dpo= Outer Diameter of 

The pulley pitch diameter is given by d pz p π (1) wherepis the nominal pitchand z p the number of pulley teeth. The radial distance between pitch diameter and pulley outer diameter is called pitch differential,u, and has a standard value for a given belt section of inch pitchand metric T seriesbelts (see Table 1). The

You can calculate the Belt length if timing-pulley diameter and center to center distance between the

When designing a linear drive you'll first want to calculate your peak starting torque, peak breaking torque and the maximum speed, 

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

application of the timing belt drive is as rigid as possible. That will guarantee high work repeatability. Drive calculation guidelines Angular drives Elatech belts can be used in angular drives as a "Twisted" drive. In such an application, it is recommended to keep a span length "lt" > 20 † b (belt width) for 90° twist. Omega drive

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
