There are more than sixty six various dimensions, sizes and types of belts that are used in the agriculture equipment industry. These various belts are used in different parts, such as tractors, combines, balers, snow blowers, tillers, mowers, harvesters and lawn and garden tractors.

V Belts are used as fan belts, timing belts, alternator belts, drive belts for mowers, and general pulley driven devices found in combines, mowers, balers, harvesters and other agricultural equipment.

The wedging action of the V-belt in the pulley groove allows them to transmit higher torque at less width and tension than flat belts. Typically, it is endless. It requires larger pulleys than flat belts because of their greater thickness. When compared to the flat belt, it is far more superior at small center distances and high reduction ratios.

You should identify it first to change a cut or damaged V belt. Written on it can be the fastest and easiest way to identify a belt which is to deduce the V belt part number.

As is mentioned above, the V-belt can be further divided into many other types such as the open-ended V-belt, V-ribbed V-belts, variable speed V-belts, cogged V-belt, and double-sided V-belt, etc. The first category is constructed the same as traditional ones except that they are open-ended and do not need metal fasteners. This type of drive has a limited load capacity and tends to be expensive. And they are useful where obstructions make access to the drive belt difficult.

The second type of products are combined variable speed V-belts that are banded together to achieve different speeds, strength and transmission capabilities. They are recommended for multi-sheave drives.

The third one allows for a greater range of speeds and better resistance to twisting while transitioning from one speed to another. It is recommended for variable-speed sheave drives that need to control speed to achieve a certain result.

The fourth category has a trapezoidal shape. It can either be a conventional or narrow raw edge cogged V-belt. The former one is designed for high-tension drives, while the latter one can be applied for all drives.

The fifth type is characterized by its hexagonal cross-section shape. According to its name, this type has two Vs with one on each side. The special shape of this type makes it to be applied in serpentine reverse bend drives where a transmission may need to drive in reverse to generate power.

The other major variant of this component is its length. The normal outside and inside circumference of the belt can be measured. However, for measuring and part number identification purposes, this is not the true circumference. The effective circumference of the belt is the part of the belt that most of the pressure is concentrated on while under word pressures. Near the cord line, there is the line generally located at the neutral axis and varies with cross section and construction. This circumference is typically a few millimeters under the top width of the belt.

Some manufacturers and users prefer the pitch length to identify belts. However, most users prefer to use the inner circumference of the V Belt for identification purposes. For example, a belt with a "C" dimensions and an inner length of ninety five (95) inches will have part number of C95. This description can be used to identify the other types for the A, B, D, Z and E.
