WitrynaHertzian fatigue cracks, either macropitting or micropitting, that start at the gear tooth surface grow at a shallow angle to the surface and opposite to the slide directions. Consequently, as shown in Fig. 2, the cracks converge near the pitch line of the driver and diverge near the pitch line of the driven gear. Kinematics.

WitrynaContact fatigue. Contact fatigue, sometimes called Hertzian fatigue, happens when repetitive, direct stresses cause abrasions or otherwise deteriorate the integrity of the gear. Contact fatigue can occur as micropitting, less than 1 mm in diameter, or macropitting, more than 1 mm in diameter. General wear.
