Project-/Bachelor Thesis: Oil flow in Roller bearings

The Institute of Machine Elements and Systems Engineering researches the fundamental structural and tribological behavior of machine elements. Validated multi-body simulation models are a cost-effective alternative to experimental tests for investigating the effects of loads that occur on individual components within a powertrain system.

In order to consolidate Europe as a pioneer of modern wind turbines (WT), the efficiency of modern WT must be constantly improved. An essential component here is the Gearbox and its lubrication system. The oil flow through the gearbox is highly affected by its roller bearings. So far, it has not been possible to quantify the effect of the oil flow through a roller bearing on the performance in the gearbox and thus the WT.

Therefore, in this work, you will help to firstly determine a real-time model of the oil flow through roller bearings. Your part will be the design and conduction of  oil-flow experiments on an existing test rig for roller bearings.

Tasks:

• Test bearing rig assembly
• Definition of a test matrix oil-flow tests
• Conduction of tests according to the test matrix.
• Evaluation of test results regarding oil flow in test bearing

Requirements:

• Independent and reliable work approach.
• First experience and/or enthusiasm for experimental work.
• Prior knowledge in Autodesk Inventor and is desirable.

We offer:

• Participation in novel research project.
• Flexibility in shaping the focus of work.
• Intensive guidance.
• Immediate start or as agreed upon.
• Very pleasant working atmosphere.
• Preparation of written Thesis in either English or German

We look forward to your application by email:
