The V-belt is probably the best-known belt of a belt drive. In common parlance, the term is often used synonymously with multi-ribbed belt or flat belt, but there are significant differences between these belts. V-belts represent a further development of the flat belt and have a trapezoidal cross-section. Due to the larger contact surface in the groove of a corresponding pulley, greater torques can be transmitted. At the same time, the bearings are protected by the higher friction. According to V belt Manufacturers, compared to the flat belt, the efficiency is slightly lower in a V-belt.
V-belt functions
The V-belt consists of several layers of high quality rubber, each of which has a different function. The following layers are distinguished: tension, compression, carrier layer, and second compression layer, wrap.
As per the knowledge of V Belt Suppliers, this industrial belt acts as an essential part of the production chain. It absorbs shocks and protects other mechanical parts.
The V-belt transfers part of the engine power to auxiliary equipment such as the generator or the air conditioning compressor. The cooling water pump or the servo pump can also be driven by it. This removes the torque from the drive pulley, which in turn is attached to the crankshaft. Depending on the engine, several V-belts can also be used, while in modern vehicles a multi-ribbed belt almost always takes over the transmission of the torque.
Usage of V belts in different Industries
V-belts are used in a wide variety of industries. Metallurgy and woodworking, mechanical engineering and machine tool building, textile and clothing production, as well as the food industry – all this is the field of application of V-belts.
V-belts are divided into classic, narrow-V, double-sided multi-ribbed and variator. Their undoubted advantages included by V Belt Manufacturers India are as follows:
- high strength and absence of external changes in the process of work;
- invariability of dimensions during operation;
- good tolerance to sub-zero temperatures;
- stable resistance to aggressive substances;
- counteraction to static charges
Replacing the V-belt
Due to the constant load, the V-belt stretches over time and loses its elasticity. This is initially noticeable to the driver by a beeping sound. Since the tension is no longer great enough, the pulleys slide, especially under heavy load – e.g. in the starting phase or with high generator resistance due to frequent use. Finally, the problem also exists in normal driving situations, until finally the auxiliary components are no longer driven, because the tractive force is no longer produced. The replacement of the V-belt must of course be done beforehand. If several parallel V-belts are in use, they should always be replaced at the same time so that the elasticity is even.
