Acquiring knowledge in the area of machine elements load distribution (gears, bearings, thread joints, chain transmission,...) regarding efficiency and operational capability. 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 meshed parts in order to achieve proper load distribution.

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 (development 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 drives load distribution. Load distribution on the simultaneously meshed gear teeth. Defining of analytical models for load distribution. Boundary load distributions (uniform and uneven) and real load distribution. Influence factors. Influence of contact lines length 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 load capacity. Rolling bearing load distribution. Load distribution between bearing rolling elements. Boundary load distributions. Influence factors. Influence of load intensity, stiffness, radial clearance and number of rolling elements on load distribution. Influence of load distribution on rolling bearing's service life and load capacity.

Depending on the interest of the candidate, the resources of the General Machine Design laboratory are available.
