Abstract

The article presents a physical model to determine the rate of wear of a motor-axial bearing of a locomotive.
The rate of wear of the model was determined in dependence with the term of operation and presence or absence of the electrostatic processing of the axial oil. It was determined that with the increase of an operation time of the axial oil in the lubricating system, its wear-resistant properties gradually deteriorate. It was proved that the use of the axial oil, which had passed ECO, reduces the rate of wear of the experimental samples.
The level of reduction of the wear rate depends on the duration of the oil operation in the lubricating system.
The largest reduction in the rate of wear (two times) is notable for new oil; the reduction for oil after locomotive’s kilometrage of 75 thousand km is about 1.68 times; for oil at the expiration date the reduction of wear is approximately 1.47 times.
The results permit to identify ways of modernization of the lubricating system to increase the resource of the motor-axial bearing.
