Currently, gear pumps are developed with a aim to increase their efficiency, reduce internal leaks, and working pressures. This development direction requires new solutions which would compensate backlash while ensuring an optimal size of the gaps for entire range One intended meet this demand is design circumferential compensation so-called integrated lips. The presented method result research...

Global competitive business market had brought increasing awareness to optimize the gear design. Gears have the advantage over friction and belt drives in that they are positive drive, a feature which most of the machine tools require, since exact speed ratios are essential. The design and manufacture of precision cut gears, made from materials of high strength, have made it possible to produce...

This paper presents the numerical elastic solution for a real problem, functionally graded chamber of hydraulic gear pumps under internal pressure. Because of the similarity and complexity for the considering geometry, a bipolar cylindrical coordinate system is used to extract the governing equations. The material properties are considered to vary along the two tangled circles with a power-law ...
