Hydraulic gear machine e.g. external gear pump, for e.g. generating hydraulic energy, has actuator device to adjust axis position during machine operation and working against shaft deflection forces, where shafts center distance is changed

Gear machine having shaft toothing for driving a gear

Gear pump or engine - has wearing plates with small grooves, facing bearing bodies, for gap-free contact

Gear machine, particularly external gear pump or external gear motor, has housing provided on outer surface with trough-like depression, and a low pressure connection is arranged at deepest point of trough-like depression

Hydraulic Toothed Wheel Machine

Hydraulic gear wheel machine i.e. external gear wheel machine such as external gear wheel motor, for generating and converting of hydraulic energy, has actuators adjusting opening independent of operating pressure during machine operation

Hydraulic gear wheel machine e.g. external gear pumps used in movable hydraulics, comprises external gear pump with gear wheel system in inner chamber and mesh supported in bearing support opposite to housing

Gear machine e.g. pump is formed with recess with two portions extended in different directions, such that pressurized fluid pass into recess in direct contact with bearing sleeve and tooth space of associated gearwheel

Hydraulic gear wheel machine

Reversible gear machine.
