The Analysis For Rexroth A6VM Piston Motor Common Breakdown:

1. In failure scenario number 22, design defects or manufacturing tolerances in internal oil passages may lead to localized cavitation, generating fine bubbles and associated noise. This fault causes torque pulsations, efficiency loss, and accelerated component fatigue. It is recommended to disassemble the motor to inspect passage geometries and machining precision, optimize the oil channel design if necessary, and thoroughly clean internal passages to prevent bubble entrapment. Additionally, consider integrating cavitation suppression devices, such as suction line throttling valves, into the hydraulic circuit to mitigate bubble formation and protect the motor.

2. In failure scenario number 23, cross-contamination within the valve block passages can cause the valve spool to stick or select incorrect channels, resulting in unstable motor operation modes. This fault manifests as the motor failing to switch displacement correctly, leading to inefficient performance or complete lock-up. It is recommended to perform ultrasonic cleaning of the valve block, inspect passage connectivity, and recondition the internal surfaces by precision honing or replating if necessary. Replace aged seals to restore tight tolerances and proper fluid separation within the valve block for accurate mode transitions and reliable motor control.

3. In failure scenario number 24, excessive axial forces within the motor can cause axial displacement and create gaps between the end cap and cylinder body, leading to leakage and performance degradation. Symptoms include increased return flow, reduced efficiency, and accelerated end cap wear. Recommended corrective actions involve inspecting the axial thrust balance rings and end cap locating pins, resizing balance rings or reinstalling alignment dowels as needed, and verifying that axial forces remain within the motor’s design parameters. Addressing these issues eliminates gaps and restores hydraulic balance for optimal motor performance.
