| Abstract | External load on a bearing which supports the shaft is, normally, composed of static and time-varying components and are essentially dynamic in nature. The external load on a bearing is transferred to the housing in which the bearing is fixed through the elements of bearing viz., inner race, rolling elements and outer race. In the present work an investigation has been made to estimate the excitations caused by localized defects on different elements, viz., inner race, rolling element and outer race, of a bearing subjected to dynamic load. In this study, the dynamic load has been considered to be composed of a static and a harmonic component resulted due to a rotating unbalance. All the kinematic and dynamic parameters of the bearing have been assessed for dynamic loading and the spectra of excitations due to defects on different bearing elements have been obtained. Numerical results have been obtained for NJ204 bearing with a known radial clearance. The results show the variation in the spectra obtained for different contributions of external static and harmonic loading. These results are expected to satisfy some of the differences in experimental and theoretical spectra obtained by earlier researchers. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
