  • New solution to prevent excessive wear in wind turbine gears 

    Farré Lladós, Josep; Westerberg, Lars; Casals Terré, Jasmina (Curran, 2014)
    Conference report
    Restricted access - publisher's policy
    During wind turbines operation, yaw and pitch bearings suffer from sequential traction-compression stresses causing millions of micro movements per cycle between the gear teeth. This situation reduces the lubricant thickness ...
  • Numerical study in a mini trochoidal-gear pump with multi-meshing contact points 

    Gámez Montero, Pedro Javier; Castilla López, Roberto; Buza Barambones, Alexis; Khamashta Shahin, Munir Andrawes; Codina Macià, Esteban (American Society of Mechanical Engineers (ASME), 2016)
    Conference report
    Restricted access - publisher's policy
    A numerical study in a mini trochoidal-gear pump based on an ingenious strategy to adapt the background mesh to the profiles shape and a new boundary condition is presented. The strategy achieves a final background mesh ...
