Application of the local meshing plane in detecting assembly and manufacturing errors of gears
AbstractIn the paper application of the local meshing plane concept is discussed and applied for overall gear quality assessment. Knowing the kinematic properties of the machine (i.e. gear teeth numbers) it is possible to modify the gearbox vibroacoustic signal in such a manner that its fragments will be linked to different rotating parts. This allows for presentation of a raw or processed gearbox signal in a form of three dimensional map on the plane “pinion teeth x gear teeth” called local meshing plane. Meshing plane in Cartesian coordinates allows for precise location and assessment of gear faults in terms of meshing quality of consecutive teeth pairs. Although the method was applied to simulated signals generated by a gearbox model, similar results were obtained for the measurement signals recorded during the back-to-back test stand experiment. Described method could be used for assessing the manufacturing quality of gears, the assembly quality as well as for the fatigue gear failure evaluation during normal exploitation.
