Abstract
Devices and systems relating to external gear machines that comprise microsurface shaping on the lateral surfaces of the gear teeth and/or bushing surfaces are provided. Such microsurface shaping may comprise a flat step to linear wedge profile, a flat step to flat step profile, or solely a linear wedge profile. The incorporation of microsurface shaping on the gear teeth and/or bushing plates contributes to improving the lubrication performance within the external gear machine and provides significant benefits, including the improvement of operating efficiency, life, and reliability of the system components. Methods for manufacturing the gear teeth and related bushings are also provided, the methods configured to optimize the overall axial balance within the system.
