ISO 2790 is an international standard on V-belts for the automotive industry which discusses the requirements and specifications for belts and pulleys.
ISO 2790 gives the best guidance on requirements for driving auxiliaries of internal combustion engines for the automotive industry.
ISO 2790 on V-belts for the automotive industry is relevant to:
A v-belt is a flexible machine element used to transmit power between a set of grooved pulleys or sheaves. They are characterized as belts having a trapezium cross-section. V-belts are the most widely used belt drives since their geometry causes them to wedge tightly into the groove as the tension is increased.
As the belt wedges into the groove, friction between the surface of the belt is increased, allowing high torques to be transmitted. The increased friction minimises the loss of power through slippage.
When we use V-belt drives for driving auxiliaries of internal combustion engines, they can help you by increasing friction and thus allowing high torque to be transmitted, which minimises the chance of loss of power. This can help the engine in improving efficiency and safety.
