Wind Gearbox HSS Vibration Analyzer
ISO 10816-21 zone check and trend analysis for gearbox high-speed shaft vibration.
High-speed-shaft bearings are the most-replaced part in geared turbines — pitting initiated by transient torque reversals shows up in the HSS spectrum months before failure. Enter your latest broadband RMS velocity and the previous reading: the tool places you in the ISO 10816-21 zone for the gearbox high-speed shaft, computes the monthly growth rate, and projects when the trend crosses the alert boundary.
Zones follow ISO 10816/20816 wind-turbine guidance: A/B = continue running, C = schedule the crane/repair, D = damage progressing. The trend matters more than the absolute number — a doubling in 3 months at any level is a fault signature.
Engineering estimate from published standards and typical equipment data. Site conditions, equipment datasheets and measured data govern the real result — confirm with a qualified engineer.
Use the free Wind Gearbox HSS Vibration Analyzer online — ISO 10816-21 zone check and trend analysis for gearbox high-speed shaft vibration. Runs instantly in your browser: no signup, no upload, mobile-friendly.

How to use Wind Gearbox HSS Vibration Analyzer
- 1Enter the current broadband RMS velocity for the component.
- 2Add the previous reading and the months between.
- 3Read the ISO zone, growth rate and projected months to alert.
Why use Wind Gearbox HSS Vibration Analyzer?
- ✓ISO 10816-21 zone boundaries for the exact component, not generic machine limits
- ✓Trend math: %/month growth and projected time to the alert zone
- ✓Component-specific failure-mode notes from field practice
- ✓Two readings and a date gap become a maintenance forecast
Frequently asked questions
What vibration level is acceptable on a wind turbine?+
Component-specific per ISO 10816-21: gearbox shafts alert around 3–7 mm/s RMS, generator bearings 6–10, main bearings far lower (slow shafts), tower-top structural readings much higher. This tool applies the right boundary set automatically — generic ISO machine charts mislead on turbines.
Which matters more — the level or the trend?+
The trend. A bearing at 60% of the alert limit doubling every quarter will fail; one sitting at 90% for years may be fine. The %/month figure and time-to-alert projection are this tool's real outputs — single snapshots only ambush you politely.
How often should turbine vibration be measured?+
Continuous CMS for MW-class machines is standard; for portable-route monitoring, monthly on known-degrading components, quarterly otherwise. The faster the observed growth rate, the shorter the interval — adjust until the next reading can't surprise you.
What causes rising vibration in the Wind Gearbox HSS Vibration Analyzer's component?+
The component note in the tool flags the classic mode — HSS pitting, electrically-fluted generator bearings, rotor imbalance at the tower. Confirm with spectrum analysis (defect frequencies) before ordering parts; broadband RMS finds the problem, the spectrum names it.
