Abstract
The foaming tendency of lubricating oils represents a serious problem in systems such as high-speed gear transmissions, pumping of high volume, and lubrication by spraying. Due to foaming, the lubrication is discontinuous, there is loss of lubricant due to overflow, which may result in mechanical damage and cavitation, with the decreased lifetime of the product and higher maintenance costs as consequences. Various procedures that simulate operating conditions have been developed with the aim of evaluating the performance of lubricating oils in actual use. The paper elaborates on various types of lubricating oils, for which the dynamics of creation and disappearance of foam has been analyzed, together with the tendency of adhesive-sliding wear at various speeds.
