Abstract:

The analysis of hydrodynamic steel sliding bearing with leaded bronze lining, which had a reduced shortened lifetime due to its unequal wear, was carried out. The lining structure of this bearing was compared to those of the bearing with a high lifetime and of the unused bearing. It was shown that the short lifetime is caused by wrong lubricating oil. The use of unsuitable oil led to the formation of hard and brittle layer containing phosphide (Cu3P) at the lining surface. The scaling off particles of the layer influenced the friction conditions and accelerated the wear.

Keywords:

Sliding bearing, Cu-Pb lining, damage, dendritic structure
