Praveen Kumar K, Janaki Manohar N

Abstract: An intent of this project is to reduce the weight of one way clutch which is being used in automotive transmission enabled sports cars. By reducing the weight we can achieve better efficiency in terms of strength and also to increase the transmission power from torque converter wherein which engaging and disengaging happens. One way roller clutch is one, when the unit rotates in one direction the rollers slip or free-wheel, but when a torque is applied in the opposite direction, the rollers lock between outer cage (cam) and inner cage, producing a wedging action and binding because of friction. The rollers are spring-loaded. Design parameters like maximum torsional deflection, minimum hoop`s stress are considered for to get increased efficiency. In order to achieve this FEA analysis and optimization technique is carried here. Optimization is the mathematical discipline which is concerned with finding the maxima and minima of functions, possibly subject to constraints. Here optimization is carried out by using the global parameters optimization technique.
