VIDEOSCOPE INSPECTIONS OF GEARBOX BEARINGS


Regular inspection of wind turbine gearboxes is critical to ensure uptime and to prevent small faults from escalating into large repairs or even gearbox replacements. Bearings are particularly vulnerable due to a combination of high, variable stresses and high speeds


GETTING ACCESS


The size of the gearbox and the location of the bearings within the gearbox make it difficult to carry out fast, reliable inspections. Even when using the latest generation of videoscopes, the dark and reflective conditions require bright, adaptive illumination to ensure a high probability of detection. Furthermore, a combination of narrow openings and the possibility of oil covering the tip of the scope means that manoeuvrability of the scope can have a big impact on the time it takes to carry out an inspection.


ACTIVE ARTICULATION


Optimising manoeuvrability helps inspectors to reach inaccessible spaces within the gearbox, for example the planetary stage bearings. The introduction of power-assisted manual articulation, such as TrueFeel articulation on Olympus’ IPLEX RX, has addressed this issue by providing intuitive, tactile feedback to the operator. It allows the movement of a 3.8mm tip through openings as small as 4.4mm without damaging or contaminating the tip.

The illumination challenge of inspecting a gearbox involves large, hollow spaces – which require high illumination – as well as reflective, metallic surfaces – which cause glare due to excess light. Intelligent illumination, such as PulsarPic illumination, can automatically adjust the light output depending on conditions, enabling the inspector to focus on inspection.


CLEARING OIL


Even the most experienced inspectors can occasionally come into contact with oil during an inspection. Oil-covered tips lead to blurry images, which usually means that the tip needs to be retracted for cleaning. However, when a special oil-clearing tip adapter is used, narrow grooves automatically draw oil away from the tip improving image quality and saving time.


A CLEAR VIEW


Speed and reliability are the critical factors in successful wind turbine inspection; the latest advances in videoscope technology can help to achieve this. Olympus’ IPLEX RX features a range of innovative technologies to inspect bearings quickly, safely and with a high probability of detection.
