Abstract
A roller one-way clutch is used for transmitting torque in one direction while running free in the reverse. A special geometrical configuration of the inner race along with rollers has been used to transmit the torque from one race to another race in one direction only due to wedging action developed at two contact regions. During working of the clutch, contact stresses are developed in races. These contact stresses are considered to be very crucial in the design of the clutch in order to transmit the required torque without slippage or failure of any part. The main objective of the present work is to design and optimize various parameters of the clutch in such a way to limit these contact stresses within the permissible limit of the material and also verifying these designs by using finite element analysis. The verification of contact stress has been done by comparing the analytical values of contact stress with FEA values. The most effective parameters which can influence the functionality of the clutch have to be identified first. The optimization is done in sense of varying these parameters by staying in geometrical design range which results in improving working life and torque transmission capability of a roller clutch.
