The Effect of Asymmetric Cutter Tip Radii on Gear Tooth Root Bending Stress

17FTM06

The tooth root fillet is where the maximum bending stress concentration region is located during torque transmission via gear pairs. An increase in gear root fillet radius provides a smooth transition from involute to trochoid, increases root critical section thickness, and the moment of inertia against bending of tooth. A 10-11% reduction in bending stress is obtained by using asymmetric cutter tip radii coefficients for two sides of the gear tooth profile with standard center distance and no tooth interference.
