| Description |
The gear/pinion of the collector mesh has failed by spalling/destructive pitting/wear. Evidences suggest that the failure was due to excessive load on the working flank of the gear/pinion teeth. Analysis shows that inadequate tip relief of gear/pinion teeth would have aggravated the situation further. The material of construction, microstructure, and case and core hardness of the gear/pinion were found to conform to specification. No metallurgical abnormalities were responsible for the failure. It may be noted that a similar failure was investigated earlier in this laboratory (refer NAL Report No. MT-FA-917-05-2005).
