Set-up

Hydraulic pumps of type PGH are gap-compensated internal gear pumps with constant displacement.

They basically comprise of housing (1.1), bearing cover (1.2), internal gear (2), pinion shaft (3), plain bearings (4), axial washers (5), end cover (6), mounting flange (7) and stop pin (8), as well as the segment filler element (9) consisting of segment (9.1), segment support (9.2) and the seal rolls (9.3).

Suction and displacement procedure

The hydrodynamically supported pinion shaft (3) drives the internally geared internal gear (2) in the displayed direction of rotation.

During the rotation, there is a volume increase over an angle of approx. 90° in the suction range. An underpressure results and fluid flows into the chambers.

The sickle-shaped segment filler element (9) separates suction and pressure chamber. In the pressure chamber, the teeth of the pinion shaft (3) engage in the space between the teeth of the internal gear (2) again. The liquid is displaced via the pressure channel (P).

Axial compensation

The axial compensation force FA takes effect in the area of the pressure chamber and is generated with the pressure field (10) in the axial washers (5).

So the axial longitudinal gaps between the rotating and the fixed parts are extraordinarily small and ensure perfect axial sealing of the pressure chamber.

Radial compensation

The radial compensation force FR acts on segment (9.1) and segment support (9.2).

Dependent on the operating pressure, the two segment filler elements (9.1) and (9.2) are pressed against the head diameters of pinion shaft (3) and internal gear (2).

The area ratios and the position of the seal rolls (9.3) between the segment and segment support are designed so that an almost leakage gap-free sealing between internal gear (2), segment filler element (9) and pinion shaft (3) is achieved.

Spring elements under the seal rolls (9.3) ensure sufficient contact pressure, also with very low pressures.

Hydrodynamic and hydrostatic mounting

The forces acting on the pinion shaft (3) are accepted by hydrodynamically lubricated radial plain bearings (4); the forces acting on the internal gear (2) by the hydrostatic bearing (11).

Gear tooth system

The toothing is an involute tooth system. Its large meshing length results in little flow and pressure pulsation; these little pulsation rates considerably contribute to the low-noise running.

PGH-type hydraulic pumps are gap-compensated internal gear pumps with fixed displacement. The hydrodynamically mounted pinion shaft drives the internal gear. The pinion shaft and internal gear tooth clearances opening in the suction range suck in the hydraulic fluid and transport it to the pressure range. The suction and pressure range are separated by the radial compensation elements and the tooth engagement between the internal gear and pinion shaft.
