ABSTRACT

The paper presents the results from studying, aggregate the wear process, indicates the

cause of wear — in failure types and organization experimental study on carbon brush and collector

wear. These results help us to forecast life of the experimental carbon brush classification, therefore

we can plan collector maintenance, repair and recovery appropriately.

Keywords: The wear process, friction, carbon brushes and collectors. "^
