Abstrakty
The paper describes the results of investigations on shrink-fitted joints. Models of the marine engine cranks and pivots were made in the scale of 1:5 considering real conditions of the large-sized crankshafts fabrication. The results of ultrasonic measurements of stresses were compared to the temperature distribution during the cooling process of the assembled couplings. The conclusion was that the unsteady stress distribution might be caused by the unsteady cooling process. The proposed model of the cooling process provided an explanation on how the stresses and deformations appear. As a consequence, more tight joints may not reveal a better ability to bear a torque load.
Przedstawiono wyniki badań nad połączeniami skurczowymi. Pomniejszone modele korb i czopów w skali 1:5 zostały wykonane z zachowaniem rzeczywistych warunków technologicznych dla okrętowych wałów korbowych. Wyniki pomiarów naprężeń metodą ultradźwiękową zostały porównane do rozkładów temperatur w czasie chłodzenia złożonych połączeń. Wykazano, że nierównomierny rozkład naprężeń może być wynikiem nierównomiernego przebiegu chłodzenia. Zaproponowano model procesu chłodzenia wyjaśniający sposób powstawania naprężeń i odkształceń w połączeniu skurczowym, które skutkują tym, że zwiększenie wcisku nie przekłada się na zwiększenie przenoszonego momentu skręcającego.
