Simple pulley test can improve drive efficiency by 10%
September 19th 2006

It’s FREE – WYKO Industrial Services is offering every person who registers for the PEMEC show using www.pemec2006.co.uk/register a free Fenner Pulley Groove gauge that could improve the efficiency of a pulley drive system by 10%.

Efficient operation of V and wedge belt drive systems depends on both the belts and the pulleys being in good condition, users of V and wedge belt drives are generally aware that the belts need replacing on average every three years, but since pulleys are made from cast iron, maintenance engineers assume that they do not wear and they tend to be overlooked.

Worn pulley grooves however can be the direct cause of more frequent belt replacements and significant drops in energy efficiency. Although they wear more slowly than belts, once a pulley groove is out of shape it can result in belt slippage, which in turn causes accelerated wear in both components, the wear rate then becomes exponential.

Help is at hand, using a Fenner Pulley Groove Gauge to quickly determine if pulley grooves are worn or not allows maintenance engineers to make an informed and swift decision on remedying any potential problem.
