WebAbstract: Methods used earlier for choosing profile shift coefficients were based on presumed advantages without physical proof justifying them. In this paper a new method is proposed which guaranties a positive influence on gear failures and on the operational conditions of gear pairs.

Web1 jul. 2024 · Profile Shift in External Parallel Axis Cylindrical Involute Gears. November 1, 2001. Early in the practice of involute gearing, virtually all gears were made with the teeth in a standard relationship to the reference pitch circle. This has the advantages that any two gears of the same pitch, helix angle and pressure angle can operate together ... Web3. New Way to Choose Profile Shift Coefficients 3.1. The Stresses of the Teeth The methods presented above look for the answer to how the sum of the profile shift coefficients Sx, which can be calculated by the sum of the number of teeth Sz and the working pressure angle awt, should be divided between the two gears in meshing.

In the analytical calculation, numerical solutions are made for four different gear mechanisms. These are negative shifted (x t = −0.5), non-shifted (x t = 0), and positive shifted (x t = +0.5 and x t = +1) gear mechanisms. Maximum tooth root stress and Hertzian contact stress for each solution is calculated.
