Span length actually defined by the placements of shafts in machinery systems. But in V-belt design, you need to calculate this value to obtain required span length of used v-belts in machineries. This is the formula of span length in V-belts;
As you see that, you need to have the information about diameters of used sheaves in v-belt design. ‘D2’ is the diameter of bigger sheave of belt mechanism and ‘D1’ is the smaller sheave. ‘C’ is an another parameter called as ‘center distance’ that you can calculate this by using this calculator avaliable in Mechanical Base.
The use of span length calculator of v-belts is simple. You just need to enter the required values inside the boxes above which are ‘C’, ‘D1’ and ‘D2’ here. Then click on ‘Calculate!’ button to obtain span length value ‘S’.
To make an another calculation, click on ‘Reset’ button, then re-enter the values.
You need to take care about your units. Use a proper unit sets to obtain proper results for it. The units of ‘D1’ and ‘D2’ are lengths. So, the obtained result’s unit is also length.
Take a look at the other engineering calculators avaliable in Mechanical Base!
If you do not have proper sets of units, you can use MB-Unit Converter for unit conversion of your values.
Mechanical Base do not accept any responsibility of calculations that are made by users by using these calculators. A good engineer must check the calculations done by hand again.
