Backlash induces gear-teeth separation or back-side tooth mesh (BTM), resulting in gear
disengagement (GD), which heavily aggravates the dynamic performance and transmission …

In oil-lubricated environments, planetary gears typically operate under conditions of high
speed, heavy load, and high oil temperatures. This can lead to excessive temperature rise …

The rack railway is widely used in mountainous areas for its strong climbing ability.
However, its dynamic characteristics have been reported only in very limited literature …

Tooth breakage caused by microcracks at tooth root produced during gear service threatens
production safety. Shot peening technology produces elastic–plastic deformation on the …

Tooth mismatch induced by backlash leads to the multi-status engagement of the internal
meshing spur gear system (IMSGS), attenuating transmission accuracy and quality. This …

Due to the friction heat flow of gear during operation is easy to cause the scuffing failure of
tooth surface, the heat transfer mechanism of planetary gear is researched in this paper, the …

Harmonic gear transmission is a principal mode for robot joint reducers, and an accurate
steady-state temperature field model of harmonic gears is vital to improving transmission …

The paper introduces a novel three-dimensional numerical model considering hardness
gradient and residual stress to predict carburized gears' total bending fatigue life. The crack …
