| Abstract | This study proposes a method to predict the efficiency of a worm gear with a plastic worm wheel. The theoretical efficiency is obtained from friction coefficient experiments and mathematical calculations. A tribometer is used to measure the friction coefficient of nylon6 on steel at various normal pressures. Gear geometry is employed to calculate the position of the contact point and the curvature at the contact point, and Hertz’ Law is employed to calculate the contact area. In order to verify the efficiency prediction method, the efficiency of a worm gear which is used in an EPS system is theoretically calculated by the method, and then, the result is compared with the measured efficiency of the worm gear. With consideration of all factors, the theoretical efficiency was very accurate, showing the same efficiency trend with the increase of output torque and little difference among the values. Their maximum values were obtained at the same output torque. This efficiency prediction method can be applied to various types of gears with plastic materials. |

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.
