v belt

Engineering a notched belt is usually a balancing act among versatility, tensile cord support, and stress distribution. Precisely designed and spaced notches help evenly distribute tension forces as the belt bends, thereby helping 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 methods, tensile cord advancements, and cross-section profiles have led to an often confusing selection of V-belts that are extremely application particular and deliver vastly different levels of performance.
Unlike flat belts, which rely solely on friction and can track and slip off pulleys, V-belts have sidewalls that match corresponding sheave grooves, offering additional surface and greater stability. As belts operate, belt stress applies a wedging power perpendicular to their tops, pushing their sidewalls against the sides of the sheave grooves, which multiplies frictional forces that allow the drive to transmit higher loads. What sort of V-belt fits into the groove of the sheave while operating under pressure impacts its performance.
V-belts are made from rubber or synthetic rubber stocks, so they have the flexibility to bend around the sheaves in drive systems. Fabric materials of various kinds may cover the stock material to provide a layer of safety and reinforcement.
V-belts are manufactured in various v belt china industry standard cross-sections, or profiles
The classical V-belt profile goes back to industry standards created 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 accustomed to replace belts on industrial machinery manufactured in other parts of the world.
All of the V-belt types noted above are typically available from manufacturers in “notched” or “cogged” variations. Notches reduce bending stress, permitting the belt to wrap easier around little diameter pulleys and enabling better high temperature dissipation. Excessive warmth is a significant contributor to premature belt failing.

Wrapped belts have a higher resistance to oils and intense temps. They can be used as friction clutches during set up.
Raw edge type v-belts are more efficient, generate less heat, enable smaller pulley diameters, boost power ratings, and provide longer life.
V-belts look like relatively benign and basic pieces of equipment. Just measure the top width and circumference, discover another belt with the same measurements, and slap it on the drive. There’s only one problem: that approach is about as wrong as possible get.
