Abstract
Formulas are proposed for the worn-layer thickness sum in contacting rapidly wearing sections of the active teeth surfaces in driving and driven helical gears, on the basis of involute-gear theory, taking account of the laws governing wear. A relation is found between the rack displacement coefficients of helical gears such that the largest sum of wear rates in those sections is minimized. Numerical solution of the equations for a helical gear with standard axle spacing permits determination of the values of the displacement coefficients such that the duration of gear operation up to the permissible worn-layer thickness sum in those sections is maximized.
