Abstract: In this work, the instantaneous and average efficiency and coefficient of friction of gear drives operating at low, medium, and moderately high speeds were experimentally and analytically ...

Abstract: “Prestressed” externally pressurized journal bearings employing capillary restrictors as compensating elements are installed on a four-square gear testing machine for the purpose of investigating ...

Abstract: In this work the authors, using a testing machine designed for this investigation, determined experimentally the variation in the friction losses in gearing during an individual tooth engagement ...
