Diagnosis of the Operational Gear Wheel Wear

Abstract

The article presents an analysis in the field of gear wheel testing method application. The results of tests of gear wheel teeth taken from a damaged gear rim are reposted. Tests were carried out on specimens to establish the causes of gear wheel tooth cracking. Macroscopic examination was made, which confirmed the occurrence of top layer spalling. An analysis to examine the damage to the surfaces of mating gear wheels is described. A destructive testing method was employed. The results of hardness and microhardness tests and metallographic analysis are presented.
