  1. 1. Pilot Study: Test Rig for Self-lubricating Kaplan Runner Bearings

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Bhairav Khadke; [2023]
    Keywords : Hydropower; Kaplan turbine; Self-lubricating bearing Test rig. Hydropower; Kaplan turbine; Self-lubricating bearing Test rig.; Vattenkraft; Kaplanturbin; Självsmörjande lager Testrigg.;

    Abstract : Hydropower has a relatively small impact on the climate and contributes to almost half of Sweden’s electricity production. Vattenfall own and operate roughly 125 large scale hydro power units of which about half utilizes a Kaplan turbine. READ MORE

  2. 2. Virtual verification and improvement of innovative wind turbine gearbox design

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Ioannis Pierratos; [2021]
    Keywords : Gearbox; Multibody Dynamics; Wind Turbine; Multikroppsdynamik MBS ; Vindkraftverk; Växellåda;

    Abstract : Cascade Drives develops electromechanical linear actuators based on multiple pinions interacting with a gear rack. With a patented load sharing mechanism, that uses flexible torsional elements, the torque is equally distributed among the pinions. READ MORE

  3. 3. Fretting in Wind Power Pitch Bearings: Micro-Slip Experiments and Bearing Test Rig Design

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Román De La Presilla; [2020]
    Keywords : Fretting; Pitch Bearing; Lubrication.; Fretting; Rotorbladslager; Smörjning;

  4. 4. Tribology of newly developed EAL versus water in hydropower turbine bearings

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Nayan Dhakal; [2019]
    Keywords : water-based lubrication; hydropower; turbine bearings; environmentally adaptive lubricants; modified water; viscosity modifiers; polyvinylpyrrolidone; poly sodium 4-styrenesulfonate ; UHMWPE; wear;

    Abstract : The increasing demand for more readily bio-degradable, renewable and non-toxic environmentally adaptive lubricants with a lower degree of bioaccumulation has escalated the investigation of water-based lubricants as the potential alternatives for conventional mineral-based oils. Water is an excellent environmentally adapted lubricant; however, it is a low viscous fluid and holds downsides of having corrosive nature and extremely low pressure-viscosity coefficient leading to insufficient load-carrying capacity.
