How to protect wind turbines – new guidance | Maintenance .

Wind turbine bearings are the largest industrial bearings used today and, with up to 70% of generator failure the result of bearing failure, maintaining them can be a challenge. The guidance has been released to coincide with the launch of Mobil SHC Grease 461 WT, a new high performance grease designed specifically for the wind sector.

Removal of Grease from Wind Turbine Bearings by .

Currently, the removal of grease from wind turbines offshore in the North Sea is done by dismantling the bearing covers and scraping off the grease. This procedure is long, labour intensive and raises

Metering grease lubrication flow in a wind turbine .

Titan Enterprises were approached to supply a small flowmeter to monitor the grease being supplied into a wind turbine main bearing mechanism. For simplicity the grease mechanism is mechanically driven from the blade rotation and therefore the flow rate is potentially very low if the blades are barely rotating.

NSK: Current trends and development projects for wind .

The first project aimed to improve the internal design. Without changing the bearing diameter or the number of rollers, the team optimised the micro-geometry’s design and production engineering while keeping the macro-geometry the same – resulting in a 15% increase in the dynamic load rating. This leads to a 70% longer calculated service life.

Wind Turbine Lubrication and Maintenance: Protecting .

Wind tower blades have bearings that will essentially feather the blade so operators can optimize the blade angle to match wind speed. The main shaft bearing and yaw and pitch drives also require ...

Greases for wind turbines - windpowerengineering.c

A manufacturer of specialty lubricants has added two more for the wind-power industry: Klüberplex BEM 41-141 and Klüberplex AG 11-462. The first is a high-performance grease with a special blend of base oil and additives to cover different lubrication requirements of individual bearing applications in wind-power stations.

Bearing grease for wind turbines - Design Engineeri

Bearing grease for wind turbines SKF has announced the release of the SKF High Load Wide Temperature Bearing Grease LGBB 2. The grease has been especially developed for wind turbine applications to provide excellent lubrication for the demanding operating conditions of blade and yaw bearings.

Better strategies for monitoring wind turbine bearin

Grease analysis for detecting abnormal wear and bearing health in wind turbines has been an effective predictor of future failures and a method to limit equipment downtime. This is especially valuable in wind applications due to the high expense of unexpected downtime.
