  • Coal Fired Power Plant Case Study Coal Crusher Gearbox

     · The ProblemCoal fired power plants typically operate several ball mills or coal pulverizing mills to crush the incoming coal to the optimum size for combustion. This means that each power generation unit has five or six mills. The gearboxes that run these coal mills are usually lubricated with high viscosity oil such as ISO VG320 or ISO VG460.

  • TECHNICAL Premature Bearing Failures in Wind

     · In most wind turbine concepts a gearbox is commonly used to step up the rotor speed to the generator speed. Today the actual service life of wind turbine gearboxes is often less than the designed 20 years. Failures can be found at several bearing locations namely the planet bearings intermediate shaft and high-speed shaft bearings (Fig. 1).

  • The Effect of Lubricant Composition on White Etching Crack

     · White etching cracks (WECs) are the dominant mode of failure for wind turbine gearbox bearings. These failures are characterized by subsurface initiation and local region of microstructural alterations adjacent to the crack faces. The definitive cause of WECs within the field is unknown because of this laboratory replication has proved difficult.
