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