Bachelor-/Master Thesis: Design and construction of a plain bearing for planetary gears in wind turbines

Webseite Chair for Wind Power Drives

The Chair for Wind Power Drives (CWD) researches the behavior of drive systems in modern multi-megawatt wind turbines. The research objectives are to increase the availability, robustness and energy efficiency of wind turbines and to reduce the cost of electricity. For this purpose, software development tools, advanced simulation methods and modern system test benches are used in combination.
In order to reduce the electricity generation costs of modern wind turbines (WT), the power density of the planetary gearboxes in WT is to be increased. For this purpose, the use of compact planetary gears with plain bearings is desired. At CWD, research is being conducted about the use of planetary gears with plain bearings in wind turbine gearboxes. In this context, a planetary gearbox is being converted from roller bearings to plain bearings and examined on a system test bench with regard to wear, among other things.
Therefore, the aim of this work is the design and construction of a planetary wheel plain bearing in a wind turbine drive train for the application on a 4MW test rig for wind energy gearboxes.


  • Research of the state of the art
  • Definition of requirements for plain bearings for planetary gear bearing arrangements in wind turbines
  • Simulative design and construction of a plain bearing
    for the planetary gear bearing in wind turbines
  • Development of a concept for the assembly of the bearing
  • Integration of a sensor concept for a condition monitoring of the plain bearing into the bearing design
  • Preparation of construction drawings

Your profile:

  • Very independent and reliable way of working
  • High interest in wind energy, drive technology and interdisciplinary issues along with a high level of commitment
  • Experience in FEM/EHD simulation is desirable, but not mandatory, for working on the research topics.
  • Experience in the field of CAD

We offer:

  • A bachelor’s / master’s thesis with an industry-related topic
  • Intensive support in a highly motivated, interdisciplinary team with a very good working atmosphere
  • Direct start possible


We look forward to your application by email:
