A6vm160

The A6VM160 is a high-power-density swashplate axial piston variable displacement motor manufactured by Rexroth, primarily used in hydrostatic transmissions for open or closed circuits. As the most widely applied medium-to-large size in this series, it is commonly found in rotary drilling rigs, construction cranes, and heavy-duty vehicle drives.


First, Core Technical Parameters

1. Size: 160 (denoting a maximum displacement of 160 cm³/rev).

2. Pressure Rating: Nominal pressure 350 bar (35 MPa), with peak pressure capability up to 400 bar.

3. Control Range: Displacement varies steplessly from maximum to zero, enabling extremely wide speed and torque regulation.

Fluid & Temperature: Compatible with mineral hydraulic oil; normal operating temperature range: 30°C to 90°C.


Second, Key Structural Features

1. Bent-Axis Design: Utilizes an axial conical piston rotor assembly. Compared to swashplate designs, this structure permits greater swash angles, delivering higher starting torque and efficiency.

2. Compact Installation: Typically features a recessed flange in the housing center. As a cartridge-type motor, it can be directly embedded into mechanical gearboxes, significantly saving installation space.

3. Performance Logic: Output speed depends on input flow and current displacement; output torque increases with pressure differential and displacement.


Third, Advantages

As a representative of swashplate variable displacement motors, the A6VM160 excels in extreme applications like rotary drilling rigs and heavy-duty winches due to its exceptional power density and control flexibility.

1. Ultimate Displacement Adjustability

This model supports continuous adjustment from maximum displacement down to zero. This extensive range allows systems to achieve extremely high rotational speeds by reducing displacement without altering input flow, or to generate maximum starting torque by increasing displacement.


2. Efficient Swashplate Design

Featuring a conical piston rotor assembly in a swashplate configuration, it delivers superior mechanical and volumetric efficiency compared to swashplate motors.

High Starting Torque: Provides greater burst force during static load starts.

Excellent Self-Priming Performance: Effectively prevents cavitation even when functioning as a pump under certain operating conditions.


3. Diverse Control Integration

The A6VM160 offers an extensive range of control modules (e.g., HD hydraulic proportional, EP electric proportional, HA high-pressure automatic control), enabling seamless “automatic shifting” functionality—automatically balancing speed and torque based on load pressure.


4. Compact and Robust Design

Installation Convenience: Cartridge-style design allows direct integration into mechanical gearboxes, significantly reducing overall equipment footprint.

High-Pressure Tolerance: With a rated pressure of 35MPa and peak pressure resistance up to 40MPa, it ensures extended service life in harsh industrial environments.
