Bonfiglioli helical-worm gearboxes, marked as VF-W series, are the most commonly used motoreductors in industrial machines.

They owe their popularity to their attractive price, availability, compact design and maintenance-free operation. A worm gearbox is a gearbox in which two elements work together: a worm (made of hardened steel) and a helix (made of bronze alloy).

Gearboxes can be mounted to devices by means of a flange, reaction arm or directly to the body. An important advantage of worm gearboxes is self-locking system. Bonfiglioli helical-worm gearboxes are marked with symbols: VF, W. The standard gear ratio of worm gearboxes is in the range from i=7 to i=100. By using a helical step R or by assembling two gearboxes we can achieve a ratio up to I=10 000.

The main components of the VF-W series of worm gearboxes are made of particularly durable materials. The worm is made of hardened steel and the helix is made of bronze alloy. Their combination in a compact casing guarantees trouble-free operation for many years. This is why these motoreductors are most often installed in industrial machines.

Basic parameters of Bonfiglioli worm motoreductors:

• direct mounting, by means of a flange or reaction arm
• self-restraint
• standard gearing from 7 to 100
• possibility to obtain a ratio of up to 10,000 (set extension),
• efficiency in the range from 40% to 85%
• very favourable price/quality ratio.

Archimedes offers Bonfiglioli worm gearboxes are marked with symbols: VF, W. Many models from the manufacturer’s wide range are available from stock.

Wherever reliability and maintenance-free operation are important, the durable Bonfiglioli motoreductors are ideal solution.
