TL;DR: In this paper, a model for the prediction of the dynamic behaviour of an external gear pump is presented. But the model is based on the ANSYS Gambit software parametric abilities.

TL;DR: In this paper, an internal gear pump with suction control is constructed to reduce undesired cavitation effects in the pressure region and to permit the oil to flow off from the diminishing displacement cells between the teeth of the gears.
Abstract: In an internal gear pump, which can also be constructed as pump with suction control, to reduce the undesired cavitation effects in the pressure region and to permit the oil to flow off from the diminishing displacement cells between the teeth of the gears, and impedance-controlled overflow passage is provided, the openings of which towards the moving displacement cells are alternately opened and closed by the teeth of at least one of the gears.

TL;DR: In this article, an analytical and experimental investigation of the bush end plates in gear pumps is presented, and it is shown that the hydrostatic and hydrodynamic moment unbalance is not of primary importance here.

TL;DR: In this article, a load proportional antibacklash gear drive system is provided wherein each portion of a split pinion gear is provided with a pressure chamber connected to a torque sensor and servo control unit for controlling the pressure applied individually to each split gear portion, against opposing tooth faces of the driven gear.
Abstract: A novel load proportional antibacklash gear drive system is provided wherein each portion of a split pinion gear is provided with a pressure chamber connected to a torque sensor and servo control unit for controlling the pressure applied individually to each split gear portion, against opposing tooth faces of the driven gear. The servo control unit provides high pressure (hydraulic or pneumatic) to a first split gear portion for drive in one direction while providing low pressure to the second split gear portion in the opposing rotational sense to maintain contact of the split gear with both faces of the driven gear at all times, thereby eliminating backlash. Upon reversal of the direction of rotation of the gear system, the servo unit provides high pressure to the second split gear portion which then acts as the driving gear, and maintains low pressure to the first split gear portion to maintain it in contact with the driven gear to prevent backlash upon reversal of the direction of drive of the gear system.

TL;DR: A pressure plate provides metering grooves in a face thereof contiguous to the gears of a gear pump as discussed by the authors, which communicate certain pockets between adjacent gear teeth with other such pockets so as to meter fluid from pockets in which fluid is trapped at relatively high pressures to those in which fluids are trapped at low pressures, thereby controlling the pressure distribution.
