Multiple V-ribbed engine belts
V-ribbed GUFERO® engine belts also known as multi-groove engine belts provide a solution for high transmission gear ratios, high speeds of the engine belt, engine belt transmission systems with many pulleys, in situations where there are engine belt pulleys with small sections and where an external tensioning pulley is used. In most cases this type of engine belt is used as a driving engine belt in compact drives in home appliances, tools and in the automotive industry. In addition, V-ribbed engine belts are used in many industrial applications, including heavy machinery. The distinguishing advantages of V-ribbed engine belts include their high transmitting power, long service life, near vibration-free running, high permitted circumferential speed of up to 60 m/s and their temperature resistance from -30 °C to +80 °C.
If compared directly to raw edge engine belts, multiple V-ribbed engine belts have the following advantages:
- high efficiency (approx. 98 %)
- the possibility of application at high revolutions
- a lower run-out of the engine belt
- a lower noise level
- the possibility to use engine belt pulleys with very small diameters (up to 18 mm for the PJ section)
- less demanding maintenance
- longer service life
