Fracture Examination of a Tube-well Water Pump Deep Groove Ball Bearing for Life Improvement using Finite Element Analysis

Abstract

Tube wells are used for watering the crops. Pump is fitted at the deep side of the tube wells. Pumps are used for supplying the water in the field. After 6 to 8 months, failure of bearing occurs. The bearing used in the pump is deep groove ball bearing. The main cause of bearing failure is misalignment of bearing on shaft at the time of maintenance, excessive loading while operating the water pump, overheating by friction during excessive operating conditions, poor lubrication and some corrosion effects. The speed of bearing shaft is 2800 rpm, which is the maximum operating speed. This failure can be examine using the engineering analysis. Some engineering modifications will improve the life of bearing and decrease the rate of failure.
