The very word poly-v is the international registered trademark of hutchinson, a show piece of the leadership qualities of this french company. Poly v-belts offer several advantages as compared to v/wedge/flat belts in terms of smaller pulley diameters, higher belt speeds, narrower face widths thus leading to efficient transmission of power. The most visible fact being that automobiles (the largest segment to use belts) has switched onto poly v for transmission. Hutchinson of france are the european leaders in poly v belts - specializing only in the development and manufacture of this type of belts. The very fact that they have more than 50% market share in the european automobile, white goods and industrial segments prove their quality and acceptability to large oem's like ford/gm/whirlpool/electrolux. The exhaustive range of hutchinson covering H, J, K, L & M sections, from lengths of 200 mm to 15, 500mm (in most sections) enable them to offer various sizes of standard lengths as required for industrial applications. Hutchinson manufactures these belts in a different way (fully vulcanized ribs of a sleeve) as against grinding by most of the other manufacturers, leading to better transmission efficiency. The very construction of the poly v-belts makes it suitable to replace all existing belt drives.
Some of the major advantages are:
•no matching of belts required - monoblock structure that eliminates flapping- as all ribs have the same length, thus providing longer life, reduced stretch and importantly higher transmission efficiency.
•smaller pulley diameters possible and with reduced face widths (due to higher power transmission) leading to extended bearing life.
•higher belt speeds, due to its construction. High speed ratios, possible (upto 1:60)
•the superior polymer and manufacturing technology of hutchinson provides reduced vibration and lesser noise (moulded ribs as compared to ground ribs of competitors). Flexonic ® - a hutchinson patent launched for household industry is available for industrial applications - enabling installation on fixed center distances, reduced noise and dampening of shock loads.
Conveyxonic® - a revolutionary poly v belt for usage in powered roller conveyors. The only technology to transport packages from 1 to 200 kg with 4 times power transmission than a round belt for rapid and smooth package flow (4m/s). Finally, we in tradelink as their long standing distributors in india, also offer assistance in design and recommend ideal poly v® - drives, using software provided by hutchinson.
