WebThe influence of rectangular and elliptical spalling on TMS was analyzed by the potential energy method (PEM). The fault feature of tooth spalling was studied by dynamic simulation and verified by experiments. It is found that the gear system will produce a periodic shock response owing to the periodic change of the number of meshing gear teeth. WebTooth spalling is one of the most destructive surface failure models of the gear faults. Previous studies have mainly concentrated on the spalling damage of a single gear tooth, but the spalling distributed over double teeth, which usually occurs in practical engineering problems, is rarely reported. To remedy this deficiency, this paper constructs a new …
WebDec 1, 2016 · Spalling is one of the common tooth surface failures of gear teeth and is defined as the formation of deeper cavities that are mainly developed from subsurface defects. The time varying mesh stiffness (TVMS) of gear pairs, gives significant information about the health of the system. WebJun 1, 2024 · Generally, spalling is caused by the interaction of a stronger pressure and higher sliding speed on the surface of gear teeth. The stiffness of a spalled gear is …
WebApr 5, 2013 · Critical failure modes for power transmission gearing include: Wear, scoring, profile pitting, tooth breakage, and spalling. In general, these can be classified into two categories: Fatigue failures and wear failures. Fatigue failures are most often associated with failures related to bending (root fillet cracks), sub-case (sub-surface) fatigue ...
