Rozbor poškození valivých ložisek u točivých elektrických strojů při přepravě a manipulaci

Abstract

This bachelor thesis deals with the damage of bearings in rotary electrical machines, which may occur during transportation and manipulation. The first chapter describes the basic classification of generator bearings. The second chapter then explores the metagraphic classification of bearings for particular components. Chapter three looks into the signs of damage encountered during operation and the main types and patterns of damage which occur in bearings. The last, fourth chapter deals with the storage and packing of machines and bearings, as well as with pre-operational checks conducted prior to running the machines.
