A case study on various defects found in a gear system

Gears are amongst the frequently encountered components to be found in rotating machinery used in various applications. Even though inexpensive, its failure can disturb the complete production in a plant resulting in unscheduled downtime and production losses. Also the detection of gear failure at correct time is of utmost importance otherwise the system may sustain bigger loss. So this paper deals with study of different gears failures of machines used in industries and the vibration based techniques used to detect these failures.
