| Abstract | A rotating shaft supported on rolling element bearings is considered. The system is known to be modeled by a pair of coupled second order differential equations involving Hertzian contact force and thus parametric excitations. In studying the stability of the system, the static equilibrium in the direction of the static load is found to linearly increases with clearance. An approximate model is obtained and conditions of validity of such a model are discussed. Cage rotation speed, static load and clearance are revealed as key parameters. Considering the Floquet formalism for stability, in the domain (clearance,speed), it is found that the domain of stability decreases for large clearance and increases for small clearance. Higher number of rolling element as well as smaller static load positively affect the stability as well. |

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.
