Analysis of Tribological Processes in Components of Massive Roller Bearings

摘要

The paper presents an analysis of tribological processes on the surface layer of large roller bearings parts carried out on bearing steel 100CrMn6. Laboratory tests carried out on roller bearings elements eg. the axle railway wagons exploitation around 600 thousand km. Modern optical microscopy with fiber optic transmission and special software was used; scanning electron microscope was applied to analyze surface stereometry; profilometers made an analyze of seizure of co-working tribological parts: roller – race roller bearings. In addition, the documentation of characteristic tribological processes occurring during the exploitation the bearings was completed. Seizure zones contact surface which occur under high and variable loads and friction were found.
