Multiple V-ribbed vee-belts
V-ribbed GUFERO® vee-belts also known as multi-groove vee-belts provide a solution for high transmission gear ratios, high speeds of the vee-belt, vee-belt transmission systems with many pulleys, in situations where there are vee-belt pulleys with small sections and where an external tensioning pulley is used. In most cases this type of vee-belt is used as a driving vee-belt in compact drives in home appliances, tools and in the automotive industry. In addition, V-ribbed vee-belts are used in many industrial applications, including heavy machinery. The distinguishing advantages of V-ribbed vee-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 vee-belts, multiple V-ribbed vee-belts have the following advantages:
- high efficiency (approx. 98 %)
- the possibility of application at high revolutions
- a lower run-out of the vee-belt
- a lower noise level
- the possibility to use vee-belt pulleys with very small diameters (up to 18 mm for the PJ section)
- less demanding maintenance
- longer service life
