This phenomenon mainly occurs in pinion gears with gear quenching, which involves the following aspects:
In high-force applications, dynamic load peaks under acceleration, braking action or vibration will cause elastic deformation in the meshing teeth.
·Center distance error
Manufacturing tolerances in gear machining, especially pitch errors, cannot be prevented, which can have a negative impact when combined with bending effects.
Most slewing drive units are mounted in a cantilevered arrangement and the deflection of the pinion shaft is unavoidable. High force will simultaneously produce elastic deformation at the interface of the slewing drive and mounting structure. This deformation can also cause meshing problems.
The three influencing factors mentioned will result in high peak loads acting on the edge of the pinion tip, which may cause the lubricant film to rupture and direct metal contact will increase the chipping effect.
