... was investigated via a power opened gear durability test rig and compared with polyformaldehyde (POM) gears. Experimental results show that PK gears under oil lubrication and grease lubrication represent the same failure mode at the same torque. The contact fatigue life of oil-lubricated PK gear was higher than...

... criterion is adopted to study the contact fatigue in a spherical asperity subjected to cyclic elastic-plastic normal loading. The fatigue damage in the asperity is predicted. The maximum fatigue damage occurs at the edge of the maximum contact area. Two typical patterns are found for the fatigue damage...

...Dong Zhu; Ning Ren; Q. Jane Wang Surface pitting due to contact fatigue is a major failure mode of many mechanical components, such as various gears and rolling-element bearings. Pitting life prediction, therefore, is vital to design and performance/reliability improvements. Conventional prediction...
