Short summary
In this paper, we use the folded section hypothesis to determinate the ratchet tooth root bending stress and provide a normal mathematical model to calculate it. This model has been proved by the finite element analysis method and the ratchet experiment. It is recommended that this model be used to predict the ratchet tooth root bending stress in the ratchet design process.
