The Analysis For Rexroth A2FE Fixed Displacemen Piston Motor Common
Breakdown:
1. Sticking Charge Check Valve Causes Cavitation Damage: ＞0.01mm
misalignment reduces charge flow ＜60%. Maintain spool cylindricity
≤0.002mm and monitor pressure every 500h.
2. Integrated Sensor Failure Degrades Control: ＞90% humidity
causes ＞5% signal drift. Upgrade to IP67 magnetostrictive sensors
with epoxy-sealed connectors.
3. Keyway Stress Concentration Leads to Shaft Fracture: ＜0.3mm
fillet radius causes ＞3.5 stress concentration. Increase to 0.8mm
with roller burnishing (＞400MPa residual stress).
