Setup of a test rig for gear measurements under static load
In order to meet climate protection targets, the trend in industry is developing towards resource conservation and energy savings through lightweight construction. Coupled with the objective of expanding the wind energy sector and installing wind turbines (WT) ≥ 5 MW, lightweight construction is also becoming significant for transmission technology. If the power of WTs increases, so does the mass and material consumption of WT components. Gearboxes also have to be dimensioned larger. In order to save resources and energy, the material consumption must be minimized in the design and manufacture of the gearboxes through lightweight construction. At the same time, the demand for long service lives of more than 20 years for wind turbine gearboxes remains. In addition, gears in wind turbine gearboxes are exposed to high dynamic loads. Due to these high requirements, lightweight gears have not yet been used in wind turbine gearboxes. Within the framework of a research project, design guidelines for lightweight gears with integrated load monitoring for wind turbine gearboxes are therefore to be developed and implemented as a demonstrator. Furthermore, to validate the design guidelines, special test rigs are to be developed in which the geometry of the lightweight demonstrator can be examined under load (static and dynamic).
The main objective of this thesis is to design and build a test rig for measuring the geometry of statically loaded gears. To validate the test rig, experimental measurements are to be carried out on a cylindrical gear under a defined load. The measurements are then to be evaluated on the basis of a model and evaluated using deviation parameters.
