... Base oil type, viscosity, and additive packages of gear lubricants influence gear failures as wear, scuffing, micropitting and pitting as well as power loss and efficiency. Numerous test methods have been developed to quantify these influences. Different test equipment like a gear test rig...

... The paper describes the design of disk machines which are used to simulate the contact and scuffing conditions in high-speed aerospace gears and rolling contact bearings. In ground gears the surface finish of the teeth is predominantly in the direction perpendicular to that in which rolling...

... This article concerns an attempt to utilize stretcher strains to determine the stress concentration factor in the elastic-plastic state of steel strip specimens having semicircular notches. The dangerous section of steel gear tooth profiles is also brought under examination. In both cases...
