Bearing Life Analysis Along With Sustainability Of Seals

Abstract Ball and rolling element bearings are perhaps the most widely used components in industrial machinery. They are used to support load and allow relative motion inherent in the mechanism to take place. Subsurface originated spelling has been recognized as one of the main mode of failure for rolling contact fatigue RCF of bearings. In the past few decades a significant number of investigations have attempted to determine the physical mechanism involved in rolling contact fatigue of bearing and proposed models to predict their fatigue lives. Rolling bearing operation is affected by friction wear and lubrication mechanisms fluid dynamics and lubrication rheology material properties and contact mechanism. Changes in rolling surfaces occur due to plastic deformation rolling contact wear and rolling contact fatigue. Wear particles can be formed and mixed into the lubricant rolling contact and rolling contact fatigue during rolling bearing operation can be diagnosed by combining measured and interpreted condition monitoring data with theory and conclusions drawn thereof can support a continuous prognosis for the remaining life. Dust and water ingress in bearings can lead to early failure of bearings. Contact seals are frequently used to keep contaminant out and lubricant inside the bearings. The sustainability of the seal is dependent on the lip contact forces. In this research an attempt has been made to arrive a common conclusion on fatigue L268321268320 calculation sustainability of seal and the method available to prevent any such failures and how to curve them thus to increase the life of bearing
