Abstract

Problems occurs in any machineries are of great distress to maintenance engineers. On several occasions the stability conditions of rotating machinery changes the operating conditions between two interconnected units of machineries. Varying situations attracts many designers and engineers for detailed investigations in the rotating systems. The occurrence of faults may be due to the two reasons, one is fault which occurred during the design stage itself, second one being fault occurring during running conditions. This paper discusses about the second situation in connection with vibration signal processing due to the faults. Satisfactory operation of machine depends on the occurrence and severity of the fault. The occurrence of the fault in any system and its changes relates to the quality of the final product. Fault depends on damage, which in turn depends on defect. The common types of machine faults are unbalance, shaft misalignment, damaged / loose bearings, damaged gears, fault of misaligned belt drive, mechanical looseness.
