AboutOff Road Belts . Off Road Belts is a premier internet v-belt distributor. Off Road Belts provides quality power transmission belts that are affordable. We have the ability to provide power transmission belts for agricultural, industrial, automotive, aggregate, oil, and lawn & garden markets. Tobe more precise, you can wrap a string tightly around the flat of the pulley where your belt rides. Mark the string where they overlap, then measure its length. Divide that number by 3.14. In this flat idler, the string measured 10 1/4''. Typing 10.25÷3.14 into a calculator gets you 3.26, so the flat diameter is about 3 1/4". VBelts come in many sizes and lengths. Here at MDS, we offer A, B, 3VX, and 5VX belts. Click the lengths to see our full selection of that type of belt or for that specific length. Shop V-Belts Now. V-Belt Dimensions EPDMand Neoprene are general purpose synthetic rubbers mostly differing in cost and a few key properties. While EPDM is cheaper, noise resistant, and a good electrical insulator, neoprene is a thermal insulator resistant to chemicals, oil, and fire. Both rubbers are commonly used in gaskets, conveyor belts, and outdoor applications. Thereforea vee drive has a maximum friction = (1/ sin β) x the flat belt friction. e.g a for a vee belt drive with an internal angle of (2 .β) = 20 o the maximum friction force for a vee belt = 1/sin (10)= 5.75 x the maximum flat belt friction. A a vee belt drive system, when correctly specified, can be expected to deliver 25000 hours of Atiming belt is always toothed because a "V" belt can slip, and that would be catastrophic for your engine (if it's an interference engine, one where the valves will collide with the pistons if they open at the wrong time). The timing belt and timing chain do the same job, but one is literally a chain. I did not mean to imply that it's a belt. Vbelts are a kind of flexible rubber band used to transfer power from a motor to a tool's wheels, pulleys, or other moving parts. However, there's a crucial difference between a v-ribbed belt and a regular rubber belt. V-belts are specially designed with a slanted, trapezoid cross-section rather than being more or less flat. Theserpentine belt usually powers your water pump, alternator, power steering, etc. Basically things that the engine will need to run. The accessory belt on the other hand usually just powers the a/c compressor. Obviously this will vary somewhat from engine to engine but this is usually the case. For example, I had a ford edge that used the Fromaligning your engine components to transferring power between your critical vehicle systems, Gates innovative synchronous belts are designed to operate at higher temperatures, higher speeds, and over longer distances.
