Design of the levers at the development of new self-equalizing thrust bearings
Original language description
Plain bearings are undoubtedly one of the essential parts of turbines and compressors. However, there are many cases in which asymmetric load occurs on the bearings due to thermal deformations, production inaccuracies or a simple deflection of the shaft. The presented research deals with some basic steps involved in comprehensive research related to developing a new self-equalising thrust bearing. It focuses on the design of its most crucial part lever, which is responsible for the proper equalising functionality of such a bearing. The study aimed to design a new type of lever geometry, create its numerical model, and, through numerical analysis and calculations, predict its useability in real conditions. According to von Mises hypothesis, stresses were evaluated, as well as contacts and stiffness according to Hertz's theory. The lever was modelled in two sizes, which suit the bearings representing the most often used types in powerful machines. For the levers' design and production, the steel 34CrNiMo6 has been used in a refined state with a yield strength of 900 MPa. The results achieved within the experimental verifications in operating conditions confirmed the correctness of the final geometry design of the levers, its sufficient stiffness, as well as good functionality of the thrust bearing and its reliability.
