Wedge Banded V-Belts:
The wedged, narrow design of the wedge V-belt provides the V-belt with better support at the center of the belt. With the narrow design of the belt, the wedge V-belt has more direct surface contact with the sheave, thus allowing for higher horse power loads and a reduced bearing load.
Wedge banded V-belts are a combination of classic banded V-belts and wedge V-belts in that they are multiple wedge V-belts banded together to make a longer, sturdier belt. Wedge banded V-belts are banded across the back of the belt to keep them together. By connecting them together, you get a stronger application and also consistent tensioning across all of the belts. It also makes the belt more rigid, which then increases friction, thus making it easier to apply to a machine. The actual function of the wedge banded V-belt is like that of the classic V-belt.
Classic V-belts are the most tried and true belts in the industry. V-belts help to solve the problem of alignment and slippage for power transmissions. They are now also the most commonly-used belts for power transmissions as well. The primary function of a classic V-belt is to disseminate power from a primary power source, such as a motor, to the secondary power unit. V-belts excel at providing the best combination of bearings, speed transfer, traction and belt-life longevity. The trapezoidal — or “V” — shape of the belt helps it to track in the similarly-shaped grooves of the machine so the belt does not slip off while in use. While the V-belt tracks in the grooves, the belt creates a deeper wedge to better handle the increasing loads, which then increases torque tension and power distribution. As friction increases, so does temperature.
V-belts are typically made out of rubber or a polymer, but may also have fibers from other materials added for reinforcement. Classic V-belts have a high resistance to temperature (-31 degrees F to 158 degrees F), but more of a limited resistance to oil.
V-belts were made originally to replace leather belts in industries such as heating, ventilation and air conditioning (HVAC), facility maintenance, material handling, oilfield supply, agriculture and rock crushers. Agriculture and industrial settings are the most common places to find classic V-belts being used. V-belts may also be referred to as light-duty (or “fractional horse power”) because they can only handle less than one horse power. These V-belts are designed with a 40-degree angle to “wedge” the belt into the groove of the pulley. There are also standard-duty V-belts, which can handle 1 horse power up to 500 horse power. The greater the load, the greater the wedging action. The manufacturing process combines a rubber compound with a polyester cord to increase strength and stability. Many classic V-belts are also available as Kevlar V-belts.
Classic V-belts generally are put into two different categories, based on construction: Envelope and raw edge.
Envelope: Also known as “wrapped” or “jacketed”; these V-belts have a fabric cover and a higher resistance to oil and high temperatures. When in a machine, they can be used as friction clutches upon start-up.
Raw edge: These do not have any type of cover, thus not as resistant to oil and high temperatures as wrapped V-belts. However, they are more efficient, generate less heat, increase power ratings, allow smaller pulley diameters, and ultimately, have a longer life.
In addition to the above categories based on construction, there are five main categories (A, B, C, D, E) of classic V-belts and they are categorized by their top width and internal length: A (1/2″ top width), B (21/32″ top width), C (7/8″ top width), D (1-1/4″ top width) and E (1-1/2″ top width).
