Abstract
ABSTRACTThe proposal of the Authors of the hereby paper is based on measuring vibrations of the gearbox housing and on the application of the generalised coherence analysis. The diagnostic model proposed by Klekot [1992. Simplified kinematic model of a spur gear with involute teeth elaborated for analysis of gear vibroactivity. Mach Vib. 4(1):261–267] was accepted as the standard, which is relatively simple, but takes into account the influence of the mesh geometry evolution during its operations on this mesh dynamics. In order to identify the proposed model, the authors performed the active diagnostic and model experiments for the toothed wheels pair. As a result, you can see how selective and practically insensitive to the interferences the measure of the evolution of gear tooth damage can be.
