Italian gearboxes boast 50% longer life

Italian gearbox manufacturer Varvel has developed a new range of inline helical gearboxes.

Italian gearbox manufacturer Varvel has developed a new range of inline helical gearboxes.

Manufactured to ISO6336/DIN3990 size standards, the key benefit to the consumer is that each unit in the RD Series has been designed to provide around 15kh life at service factor SF1.

Other manufacturers only design around 10kh, and so Varvel offers 50% more life at prices competitive with manufacturers already using the ISO6336 footprint for their inline helical units.

There are five different size options, offering 28 ratios through two- and three-stage reductions.

Powers range from 0.06 to 9.2kW, ratios from 2.5:1 to 630:1 and output torques from 1.0 to 635Nm.

Another key benefit for the consumer is that the units are compatible with standard IEC frame size motors, offering greater flexibility and less expense to the replacement user (with no need for special motors) and a more familiar territory for the design engineers.

The housings are pressure die cast to AISI 12 Cu2Fe, with the gears manufactured in steel 20MnCr5 case hardened.
