The right Belt
What is the right Belt for the saw? We have had some experience with different kind of V-belts.
There are three main categories to choose from: regular v-belts, cogged belts and link belts .
The photo at the left shows a typical link belt.
The alternative is using a normal or a cogged V- belt. Regular V-belts are the least suited for the purpose, cogged belts are more flexible and adequate for the task.
These are available nearly everywhere and are also much cheaper than link belts.
The belts should have an AX section (1/2" or 13mm wide) to handle the load.
Check that the profile of the belt fits the profile of the pulleys. The right belt lays with its top flush with the pulley outer diameter and should NOT touch the pulley body at the bottom. V-belts work using friction of the angled sides against the equally inclined pulley inner faces.
How many are necessary? New V-Belts are rarely perfectly round when lying flat on a table. This imperfection can cause vibration on the system. Using two belts helps to cancel this effect.
A single belt will also handle the load so if one belt breaks during work you can go on until you get a spare. Things usually break always when you need them most. On the other hand, I never had a broken belt as yet.
To get the right length of the belt use an online calculator. Just type in the diameter of both pulleys, distance between shafts and the profile of the belt. The calculator will tell you the right length.
