Product Description
Excavator Travel Motor Reduction Final Drive Assy SK230-6 Excavator Hydraulic Travel Motor Parts
The excavator swing reducer (swing gearbox for short) is a core transmission assembly that connects the slewing motor with the large slewing gear ring. Its key functional purpose is reducing rotational speed and raising torque output, enabling smooth 360‑degree all‑round rotation of the upper superstructure.
Basic Component Framework Layout
Sun Gear: Attached to the slewing motor spline teeth section, it imports high‑speed rotational power energy source.
Planet Gears: 3‑4 gear pieces per stage, rotating circumferentially around the sun gear while self‑rotating to transmit torque force energy.
Ring Gear: Stationary fixed on the reducer housing casing and meshes with planet gear set assemblies.
Planet Carrier: Outputs driving power energy to operate the lower small drive pinion gear wheel component.
Brake: Integrated wet‑type multi‑disc brake system mechanism; spring force engages it and hydraulic pressure releases it, avoiding reverse backward rotational movement function.
Housing & Bearings: High‑strength cast/forged steel housing casing structure, supported by heavy‑load‑capacity rated bearings, dust‑proof and leakage‑preventive service performance.

Power energy with high rotational speed and low torque force from the hydraulic motor is conveyed sequentially via the sun gear, primary first‑stage and secondary second‑stage planetary gear assemblies to the output planet carrier unit. The pinion gear spins slowly at low rotational speed with high torque output force, meshing with the inner gear ring of the slewing bearing component to drive upper‑body slewing motion function.
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.
