Applications:
1. In mining equipment, the A2FM motor is engineered to deliver
robust performance even in harsh underground conditions. Integrated
with an axial piston motor, it offers rapid start-up, precise pressure control, and enhanced
efficiency under heavy loads. The advanced design minimizes
internal leakage and optimizes flow paths, ensuring stable
operation during excavation and ore transport. Its compact and
durable construction reduces maintenance downtime, ultimately
contributing to improved safety and productivity in challenging
mining environments, guaranteeing consistently continuous
performance and operational excellence.
2. In mining equipment applications, the A2FM motor delivers high
efficiency and reliable performance for heavy-duty excavation and
ore transport tasks. When combined with a hydraulic motor, it offers rapid response and precise control even under extreme
pressures. Its innovative bent‐axis design and optimized flow
channels reduce leakage and energy consumption, thereby enhancing
overall system efficiency. This integration ensures operational
safety, minimizes downtime, and boosts productivity in the
demanding conditions of modern mining operations, ensuring maximum
output and always consistent performance.
3. The integrated piston ring design minimizes internal leakage
during heavy-duty rotation, maintaining volumetric efficiency above
95%. High power density (1.2 kW/kg) reduces swing mechanism weight
by 15%, while optimized heat dissipation limits oil temperature
fluctuations to ±5°C during continuous operation.
Competitive Advantage:
1. With modular flanges compliant to ISO 3019-2 and SAE J744
standards, the hydraulic motor enables rapid planetary gearbox
replacement on marine deck machinery, reducing port equipment
downtime by 50%.
2. The A2FM motor features an integrated one‐piece tapered piston
design with advanced sealing rings, which provide exceptional
leakage control and long‐lasting durability, and when combined with
a hydraulic motor, it ensures consistent pressure stability and reliable
performance, making it the optimal choice for precision hydraulic
systems in industrial applications, delivering remarkably effective
performance.
3. The A2FM motor features an economical design that reduces
production costs while delivering high performance, combining
state‐of‐the‐art manufacturing techniques and cost‐effective
materials, and when integrated with a piston motor, it provides reliable, efficient hydraulic power, making it a
smart investment for industries seeking sustainable and
budget‐friendly solutions for long‐term success.
The Analysis For Rexroth A2FM Fixed Displacemen Piston Motor Common
Breakdown:
1. Inadequate Housing Cooling Causes Oil Overheat: Conical roller
bearing clearance >0.08mm causes >5m/s² radial vibration.
Adjust preload to 120-150N·m with hydraulic tensioner and
relubricate with NLGI 2 grease.
2. A reduction in output torque may result from low system
pressure, aging seals, or internal leakage, adversely affecting
load capacity and efficiency. Reduced torque directly lowers power
output. A detailed inspection of the piston motor and hydraulic parameters, followed by timely component replacement,
is necessary to restore performance.
3. Erratic speed control in the A2FM motor may be caused by
irregular flow regulation, pressure fluctuations, or internal
leakage, leading to uneven operation and sluggish response. It is
essential to inspect the control valves, clean the flow channels,
and evaluate the hydraulic motor to ensure accurate speed regulation.
