High Reliability Claimed For Variable-Speed Planetary Gearbox


Published:

Voith said a survey taken in early 2013 indicates that the operational availability of its variable-speed planetary gearbox Vorecon was 99.98% with a mean time between failures (MTBF) of 48 years.

A total of 201 Vorecon gearboxes — including model years 1987 to 2010 — rated at up to 41,500 hp (31 MW) were subjected to reliability testing.

Voith reported that, when compared with previous testing from 2005, the statistical overall operating time of the variable-speed planetary gearbox increased by a factor of almost four, from 2,095,921 hours to 8,065,000 operating hours. Hence the statistical availability estimate of 99.98%.

Voith said the reliability of drive components is an important factor when calculating the life-cycle costs of a system. It said not only does the high reliability of the Vorecon gearbox decrease drive system downtimes, it also reduces the associated operating costs.
