Review on Tooth Flank Fracture Failure of Hardened Gears
Jixie chuandong, 2022 There is a new tooth failure mode for hardened gears called tooth flank fracture(TFF). ISO published a technical specification for calculating the load capacity of tooth flank failure in 2019.

Parameter study on the calculated risk of tooth flank fracture of case hardened gears
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2017 Due to better material qualities, new surface finishing methods and better heat-treatment process reliability, flank surface damages, such as pitting or micropitting, can be prevented in a reliable manner.

A Contribution To Study The Tooth Flank Fracture (TFF) In Cylindrical Gears
Procedia Engineering, 2018 Abstract The Tooth Flank Fracture, TFF, is a failure mode observed in the surface-hardened of gear tooth flanks. There is a fatigue phenomenon which initiates from a subsurface crack that occurs in the transition zone between the hardened layer and the core structure of the tooth.

Shock and VibrationTooth flank fracture (TFF) and tooth interior fatigue fracture (TIFF) usually occur on case-harden gears in electromechanical coupling systems, both starting from the core caused by metal fatigue. The cracks propagate rapidly compared with the total life

A standardizable approach for Tooth Flank Fracture
Forschung Im Ingenieurwesen/Engineering Research, 2022 AbstractUltrasonic scanning of large spiral bevel gears and the subsequent fracture analyses of early-stage tooth flank fractures imply a mode II crack initiation under surface-parallel, orthogonal shear stresses. An iteration of the Dang Van criterion is presented that focuses exclusively on surface-parallel material planes, yielding a standardizable ...

Forschung Im Ingenieurwesen/Engineering Research, 2023 AbstractAs a result of the enhanced of load-carrying capacity with regard to pitting and tooth root breakage, generation of tooth flank fractures became more frequent. This type of damage differs from existing fatigue damages on the tooth flank in that crack initiation takes place below the case hardened surface layer and the tooth breaks in the area ...

Prediction model of gear tooth flank fracture considering interfacial friction
Jixie qiangduUnder the fatigue loading condition, tooth flank fracture, crack source initiated at the subsurface position, is a subsurface fatigue failure. The failure mode is closely related to the local material strength and local stress state at the internal ...

The concept of the average stress in the fracture process zone for the search of the crack path [PDF]
Fracture and Structural Integrity, 2015 The concept of the average stress has been employed to propose the maximum average tangential stress (MATS) criterion for predicting the direction of fracture angle.
