Gear tooth sliding friction appreciably increases the magnitudeof tooth root bending stresses in both the driving and drivengears. Compared to situations devoid of friction, these stressesare decreased in the approach portion of the mesh but are increasedin the recess portion. Even coefficients of friction as low as 0.06can change the point of tooth-load application for maximum bendingstress in the driven pear from thehiehest-point-of-sinple-tooth-contact to the && p& atthe beginning of recess action.
An analytical approach is described in the case where the drivenload is constant and the coefficient of sliding friction remainsunchanged throughout the mesh’s entire contact zone. Equations arederived and effects demonstrated.
