Acquiring knowledge in the area of machine elements load distribution (gears, bearings, threaded joints, chain transmission,...) regarding efficiency and operational capability. Knowledge and skils improvement. Synthesising the acquired knowledge and skills with previously acquired knowledge. Establishing a correlation between the intensity of the load to be transferred and stiffness and accuracy of composite parts in order to achieve proper load.

Students will be able to: use the scientific literature on selected areas from the scope of Course; independently solve a scientific-research problems from selected area (making of appropriate analytical, numerical and experimental models); individually or as a team member, to write scientific research papers; ability to transfer knowledge and skills to others.

Gear pairs load distribution. Load distribution on the coupled pairs of gear's teeth. Defining of load distribution analytical model. Boundary load distribution (uniform and uneven) and real load distribution. Influence factors. Contact line lenght analysis regarding to load distribution uniformity. Boundary conditions defining. Influence of load intensity, stiffness and gear teeth production accuracy on load distribution in operational conditions. Load distribution influence on gear teeth capacity. Rolling bearing load distribution. Load distribution between rolling bearing compšonents. Boundary load distributions. Influence factors. Influence of load intensity, stiffness, radial clearance and number of rolling bodies on load distribution. Influence of load distribution on rolling bearing's service life and capacity.

The experiment setting, the flow and analysis of experimental results.
