Belt classic v-belts a13

V-belt profile A is a type of V-belt used to transmit mechanical energy in various mechanisms, such as drives in industrial plants, automobiles, household appliances, etc.

Features of profile A

V-belts have a wedge-shaped cross-section. Their shape is similar to a triangle with rounded corners.
The width of the belt is 13 mm.
The belt height is 8 mm.
Minimum pulley diameter - 71 mm (this limitation is important to maintain efficiency and avoid overheating)
Profile angle of 40° (this affects its ability to transmit power efficiently).

The A profile V-belt is used in conditions where medium-sized power transmission over short or medium distances is required.

Materials of manufacture

The belt casing (the main material is a rubber compound that may contain components such as polyurethane or rubber to provide the necessary elasticity, wear resistance, and ability to withstand high loads).

Belt reinforcement (the reinforcing layer consists of polyester or nylon yarns to ensure shape stability and durability during operation).

Belt coating (can be coated with protective layers to increase wear resistance or protection against aggressive environments (oil-resistant coating or antimicrobial properties).

Functional characteristics

Coefficient of friction (A profile V-belts have a sufficient coefficient of friction to transmit medium loads, but in some cases it may be necessary to use special seals or anti-friction coatings to reduce wear).

Temperature range (profile A V-belts operate in the temperature range from -30°C to +80°C, but depending on the material, they can be designed to operate in a wider temperature range).

Working load (used for medium loads).

Maximum rotational speed up to 30 m/s (higher speeds may require additional stronger materials or special designs).

Main characteristics

- good flexibility and high speed capability;
- high power transmission capacity under moderate loads;
- suitable for medium and low speed operation.

Types of profile A V-belts

- belts with a coating to increase wear resistance;
- belts with reinforced elements for additional strength;
- belts with seals for operation in aggressive environments.

Designation

According to the GOST 1284-89 standard, the type of profile (A) is indicated on the belt, and the parameter of the calculated length along the cord (Lw) in mm is indicated by a number - A-1000.

According to the American RMA standard, the type (A) is indicated in Latin, and the length along the inner edge (Li) in inches is indicated by a number - A38.

According to the European standard DIN 2215, the numeral (13) is indicated and the length along the inner circumference (Li) in mm is written - A13x1000.

Advantages of the A profile V-belt

- easy to install and operate due to standard dimensions and shape;
- cost-effectiveness (they have a more affordable price);
- high power transmission efficiency at moderate loads and speeds;
- wear resistance (due to the use of high-quality materials, such as rubber with reinforcing elements, the belts are resistant to wear under normal loads).

Profile A V-belts are used for

- for ventilation systems, pumps, generators, medium-power electric motors;
- for agricultural machinery, drives for various devices and mechanisms;
- in drives for some types of household appliances or auxiliary systems;
- drives for washing machines, compressors, air conditioners.

Profile A V-belts are widely used due to their versatility and ability to work effectively in a variety of conditions.
