Abstract

Two oil pump bevel gears suffered both breakage and wear. The oil pump was a gas turbine oil pump that had been in service for 3 years. Material and case-hardening examinations showed that both of these were satisfactory. Also, lube oil analysis showed no abnormality of any kind. The probable mechanism for the breakage and wear is shock overloading followed by abrasive wear caused by the debris of the broken teeth.
