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 1. SERVICE LIFE AND WEAR

摘要

We developed a method for the numerical evaluation of the total influence of correction and wear of the teeth on the service life of cylindrical gears and contact stresses. The results of numerical calculations make it possible to establish the qualitative and quantitative regularities of the influence of both 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 shifting coefficients for which the service life is maximum as compared with the uncorrected engagement. It is also demonstrated that the actual period of operation and load-carrying capacity of the gear is higher if we take into account the changes in the initial profiles of the teeth as a result of their wear.
