Basic Component Framework Layout

Typical Malfunction Manifestation Phenomena & Root Cause Analysis Factors

• Irregular abnormal acoustic noise / Choppy intermittent operational movement status: Gear surface wear abrasion and pitting corrosion damage defects, bearing functional failure breakdown damage issues, inadequate insufficient or impurity‑containing contaminated lubrication fluid medium, improper meshing backlash gap size of gear pair components.
• Oil infiltration permeation and leakage malfunction problems: Worn degraded oil seal ring components, housing structural crack fissure damages, overfilled excessive lubricant liquid level height parameter, clogged blocked ventilation breather port opening outlet.
• Sluggish slow‑moving or insufficient‑power weak slewing motion performance: Worn gear and bearing component assembly parts, incomplete brake release mechanical action function, hydraulic motor internal leakage bypass flow path mechanism, mismatched non‑compatible reduction transmission gear ratio parameter.
• Excessive temperature rise overheating condition phenomena: Low deficient oil content volume or degraded lubricant physical‑chemical property characteristics, overload heavy‑load working operation mode conditions, brake drag resistance friction force energy, insufficient inadequate heat emission dissipation efficiency performance.
• Gear jumping slipping / Tooth breakage failure damage incidents: Sudden impact loading pressure forces, foreign object debris particle intrusion into internal mechanism components, fatigue‑caused deterioration wear damage issues, shaft alignment misalignment deviation errors during assembly installation procedure processes.
