Sažetak
In spite of numerous and expensive researches in the field of fatigue, cracks and failures caused by fatigue occur every day in all fields of human activity. Because of that, special attention should be paid to fatigue crack repairs as well as fatigue crack avoidance. The fatigue cracks and failures in large gear wheel (6.8 m diameter) of cement mill are described and analysed in details. After 20 years in service, the great gear wheel of cement mill failed due to fatigue. When the whole mill plant was stopped and inspected, additional seventeen fatigue cracks have been found at the tooth fillets. The complete analyse and repair procedure was carried out and each of its steps is briefly explained.
