Sažetak
In this paper the term gearing is applied to one stage of reduction gearing consisting of two meshing gears. The main focus is on defects that have to be detected in a timely fashion. These include mesh defects that change the condition of contact between teeth in the mesh zone, and individual tooth defects, particularly wear, cracks and spalling (pitting). When defects are present that change the condition of the contact between teeth in mesh, vibration increases at the gear mesh frequency and its multiples. Defects include, displacement of one gear against another, misalignment of shafts and bad lubrication. This increase is also a traditional diagnostic symptom of gear defects. If a specific tooth is worn, cracked or a part of a tooth is missing, then once during each revolution of the faulted gear a shock will occur between the gears. Vibration of the gear supporting structure will increase at multiples of the rotational frequency of the faulted gear. This increase is a traditional diagnostic symptom of the faults identified above.
