A method for the evaluation of the influence of correction and wear of the teeth of a cylindrical gear on its durability and strength. Part 2. Contact strength

Materials Science Aims and scope

We propose a method of integration for the numerical evaluation of the influence of correction and wear of the teeth on the service life of cylindrical gears and contact stresses. The numerical results enable us to establish the qualitative and quantitative regularities of the influence of structural (angular correction of the engagement) and operating (linear wear of the teeth) factors. It is shown that the angular correction enables us to get the optimal displacement coefficients for which the service life is maximum as compared with the uncorrected engagement. It is also established that the actual operating time and load-carrying capacity of the gear are higher in the case where the changes in the initial profiles of the teeth caused by wear are taken into account.
