Until about fifteen years ago, a reduction or multiplication gearbox was generally a very robust machine, often oversized and with a large oil sump.

Nowadays, exasperated production needs together with profit margins shrinking have meant that even seemingly simple machines need to be completely reshaped, in order to obtain smaller dimensions, higher transmission ratios and lower lubricant amount.

A gearbox has become much more stressed than ever before, with very high specific loads and operating temperatures.

The lubricant useful life has generally got shorter, but this does not preserve the gearbox from damage.

Only an oil analysis program that keeps wear metals trend under strict control (by RDE spectrometry), paying a special attention to ISO 4406 contamination code and to proper lubricant viscosity, can protect the gearbox from unexpected breakdowns and allow to optimize lubricant management.
