Product Description
Rexroth A6VE Variable Displacement Pump Series
The Rexroth A6VE 28/55/80/107/160/250 piston pump series serves as the core power component for heavy-duty hydraulic drive systems, featuring extensive variable control options and extremely high power density. These pumps efficiently convert hydraulic energy into mechanical energy while enabling stepless adjustment of output speed and torque to accommodate various complex working conditions.
Technical Specifications & Working Principle
Operating Principle
The A6VE motor operates on the inclined disc axial piston principle. High-pressure oil drives plungers in reciprocating motion, with the plunger assembly applying force to the inclined plate to rotate the output shaft connected to the cylinder body. By adjusting the tilt angle of the inclined plate, displacement and output torque can be precisely controlled.
Core Product Features
- High performance capability: withstands high working pressures with wide speed range and robust power output
- Efficient variable control: supports multiple control methods including electro-hydraulic proportional (ED), hydraulic remote (HD), constant power (LA)
- Extended service life: heavy-duty bearing design, optimized friction pairs, and internal circulation lubrication ensure stable operation in harsh environments
- Low noise optimization: advanced manifold design reduces pressure pulses and operating noise
- Highly modular design: multiple displacement options, shaft ends, flanges, and control configurations support customized solutions
Control Method Specifications
| Control Type | Description | Application |
|---|---|---|
| HD Control | Hydraulic remote control via external hydraulic signals | Basic hydraulic systems |
| ED Control | Electro-hydraulic proportional control using electrical signals (0-10V) | Automation systems, PLC integration |
| LA Control | Pressure-related automatic control / constant power control | Excavators, engine overload prevention |
| DA Control | Dual control combining pressure and speed sensing | Complex drive systems |
| EZ Control | Electric control via servo motors | Precision applications |
Application Areas
The Rexroth A6VE variable displacement motor is widely implemented in applications requiring broad stepless speed regulation and strong driving force:
- Construction machinery: excavator walking drives, rotary drilling rig main winches, concrete pump truck mixing systems, crane slewing mechanisms
- Mining machinery: underground loaders, mining drilling rigs, conveyor belt drives
- Agricultural machinery: large combine harvester walking systems
- Marine engineering: deck machinery (winches, anchors), servos
- Industrial applications: injection molding machines, metallurgical equipment, test bench drivers
Professional Selection Guide
Proper selection of A6VE piston pump models requires comprehensive parameter evaluation:
- System pressure requirements: maximum continuous working pressure and peak pressure
- Displacement needs: maximum and minimum required displacement (ml/r)
- Control method: selection based on automation level and functional requirements
- Installation interface: confirmation of flange standards (SAE, ISO) and shaft extension form
- Additional functions: evaluation of integrated flushing valves, parking brakes, or oil replenishment pumps
Frequently Asked Questions
Q: What is the difference between A6VE motor and A6VM motor?
A: A6VE hydraulic pump is a variable motor, while A6VM is a variable pump. Although structurally similar, their functions differ completely: A6VE converts hydraulic energy into mechanical energy (motor), while A6VM converts mechanical energy into hydraulic energy (pump).
