v belt

Engineering a notched belt is certainly a balancing act among flexibility, tensile cord support, and stress distribution. Precisely formed and spaced notches help to evenly distribute stress forces as the belt bends, thereby assisting to prevent undercord cracking and extending belt lifestyle.

Like their synchronous belt cousins, V-belts have undergone tremendous technological development since their invention by John Gates in 1917. New synthetic rubber substances, cover materials, construction strategies, tensile cord advancements, and cross-section profiles have led to an often confusing selection of V-belts that are extremely application specific and deliver vastly different degrees of performance.
Unlike smooth belts, which rely solely on friction and will track and slide off pulleys, V-belts possess sidewalls that match corresponding sheave grooves, providing additional surface area and greater stability. As belts operate, belt tension applies a V Belt wedging pressure perpendicular to their tops, pressing their sidewalls against the sides of the sheave grooves, which multiplies frictional forces that permit the drive to transmit higher loads. What sort of V-belt fits in to the groove of the sheave while operating under pressure impacts its performance.
V-belts are made from rubber or synthetic rubber stocks, so they possess the versatility to bend around the sheaves in drive systems. Fabric materials of varied types may cover the share material to supply a layer of security and reinforcement.
V-belts are manufactured in a variety of industry standard cross-sections, or profiles
The classical V-belt profile goes back to industry standards developed in the 1930s. Belts manufactured with this profile can be found in many sizes (A, B, C, D, E) and lengths, and so are widely used to replace V-belts in old, existing applications.
They are used to replace belts on industrial machinery manufactured in other areas of the world.
All of the V-belt types noted over are usually available from producers in “notched” or “cogged” variations. Notches reduce bending stress, enabling the belt to wrap easier around small diameter pulleys and enabling better heat dissipation. Excessive temperature is a significant contributor to premature belt failing.

Wrapped belts have an increased level of resistance to oils and severe temperature ranges. They can be utilized as friction clutches during set up.
Raw edge type v-belts are more efficient, generate less heat, enable smaller pulley diameters, increase power ratings, and provide longer life.
V-belts appear to be relatively benign and basic pieces of equipment. Just measure the best width and circumference, discover another belt with the same measurements, and slap it on the drive. There’s only one problem: that strategy is approximately as wrong as possible get.
