  - TRIBOLOGY INTERNATIONAL - Year 2023

  The goal of the present paper is to investigate wear properties of journal sliding bearing operating in the conditions of contaminated water lubrication. Several bearing materials and bearing sleeve designs (differing in the axial grooves position and their shape) were tested experimentally under typical operating conditions in a dedicated test rig, which was equipped with a lubricating system, enabling lubrication with contaminated...

• Investigation of the thermal effects in water-lubricated journal bearings with axial grooves

  Publication

  - Year 2019

  Water-lubricated hydrodynamic journal bearings are frequently applied as stern tube bearings due to their advantages over other bearing types. They are environmentally friendly, can operate without sealings and in conditions of low friction losses. The most popular are bearings with open axial grooves, which require, for proper operation, forced axial flow of the lubricating water. Correctly designed and operated stern tube bearings...

  Przedstawiono relacje pomiędzy przebiegami obciążeń dynamicznych a stanem naprężeń w warstwie nośnej łożysk ślizgowych. Porównano przebiegi naprężeń dla maszyny badawczej MWO (z wirującym wektorem obciążenia) do naprężeń charakterystycznych dla maszyny SMOK (z jednokierunkowym zmiennym wektorem obciążenia).
