V-belt is the main connecting device used in the manufacture of various types of machine tools, mechanisms and machines with moving components. This tool transmits the inertial rotational movements of the engine (or any other mechanism) and brings them into final contact. At the same time, V-belts bypass the corresponding pulleys during operation and transfer of forces from one mechanism to another.
It is worth noting that the section of this tool forms a kind of isosceles trapezium. Moreover, its shape may differ significantly from the standard according to which this belt model is produced.
Features
Each model of the V-belt is made using a special technology, taking into account the addition of several layers of rubber, fastened together with a high-quality adhesive. The main layers of this tool are:
- Wrap cover.
- Compression and stretch layer.
- Traction layer.
Each of the above layers allows the product not to lose its elasticity properties under the enormous loads that affect it during engine rotation and transmission of traction. Thus, the presence of several layers and coatings in the composition of this device gives a guarantee for the longest possible period of its operation. V-belts can withstand enormous loads for a very long time and not tear to the point of wear. However, if at least one tear has formed on its surface, this means that such a tool is no longer suitable for further use. It is simply impossible to repair or restore the properties of such a belt, and the presence of cracks and other deformations will certainly lead to a break in the mechanism. When this happens, it is a matter of time, but the fact that the damaged layer of the device will constantly aggravate the performance of the entire mechanism remains unchanged.
Rubber Quality
Only the most heat-resistant and oil-resistant grades of rubber can be included in the composition of such a part as a V-belt. These requirements are determined by the operating conditions of this mechanism, since its operation is always accompanied by constant heating and friction. In addition, the V-belt must have high wear resistance qualities. In some cases, the temperature of this device during continuous operation can reach more than 100 degrees Celsius. Considering that such a V-belt is inconstantly suspended and transfers forces from one mechanism to another, low-quality parts will fail immediately after the first hours of operation. Real belts (for example, those used for timing cars) can work up to 80-90 thousand kilometers without a single tear or deformation.
Textile fiber
To achieve maximum strength and wear resistance, these tools include a special textile fiber. On broken belts, it can be seen on the very first layers - these are thin threads intertwined with each other, which are very difficult to break even with a knife.
