Rexroth A8VO variable double hydraulic pump parts

The Rexroth A8VO is a variable displacement, bent-axis double hydraulic pump designed for demanding open-circuit applications. Its key parts and subsystems include:

• Housing and Port Plate: The robust cast housing encloses all components. The port plate, with kidney-shaped flow channels, directs fluid between the inlet and outlet.

• Drive Shaft and Barrel Assembly: The drive shaft transmits power. The cylinder barrel, driven by the shaft, contains the piston bores.

• Piston and Slipper Assemblies: Multiple pistons (usually seven or nine) are housed in the barrel. Each piston, connected via a ball joint to a slipper, runs on the valve plate's control surface. The slippers rotate on a spherical segment, allowing the swivel angle.

• Bent-Axis Design Components: The core of the variable mechanism. The swashplate or housing flange (yoke) can be pivoted. The adjustment mechanism, such as a hydraulic servo piston controlled by a pilot valve, changes the swivel angle, altering piston stroke and thus pump displacement. A feedback lever ensures precise positioning proportional to the control signal.

• Valve Plate (Control Surface): A critical wear part that provides the sliding surface for the piston ends and contains the arc-shaped control slots for fluid distribution.

• Control Options: Integrated or attached devices regulate displacement. These include the Pressure Controller (HD type), Flow Controller (FR type), Power Controller (LR type), and electro-proportional controls. Components include spools, springs, pilot valves, and damping elements.

• Case Drain and Seal Arrangement: Manages internal leakage (case flow) for cooling and lubrication. Features shaft seals and port seals to separate high-pressure, low-pressure, and drain lines.

• Auxiliary Parts: Includes mounting flange, shaft seal, bearings (to handle radial and axial loads), and pressure relief or check valves for overload protection.

In summary, the A8VO's design focuses on its durable rotating group (barrel, pistons, slippers), the pivotal bent-axis yoke for variable displacement, and advanced electro-hydraulic controls, all housed in a robust casing for reliable high-pressure performance.

Parts list

Q1:What is the core functional group of rotating components in the A8VO pump, and what are its main parts?

A1:The core rotating group is the bent-axis piston assembly. Its main parts are the drive shaft, the rotating cylinder barrel with its bores, the pistons housed within them, and the slippers connected to each piston via a ball joint. This entire group converts rotational drive into hydraulic flow.
