GFT80-185 Travel Reducer: Technical Overview
(Professional Analysis for Tracked/Wheeled Construction Machinery Applications)
1. Product Positioning & Core Functions
TheGFT80-185 Travel Reduceris aplanetary gearboxengineered for tracked or wheeled construction machinery, part of the high-performance GFT series. Its primary role is to convert high-speed, low-torque input from hydraulic motors or electric motors into low-speed, high-torque output, driving the vehicle’s travel system (e.g., crawler tracks, wheels). It is widely used in heavy equipment such as excavators, graders, and drilling rigs.
• Key Applications:
• Tracked vehicles (excavators, bulldozers)
• Wheeled construction machinery (rollers, crane chassis)
• Mining/port heavy-duty transport vehicles
2. Model Nomenclature Breakdown
• GFT: Product series designation (typically stands for "Gearbox for Tracked/Wheeled Applications").
• 80: Indicates model size or torque class (correlated with input torque and motor power compatibility).
• 185: Represents the reduction ratio or torque rating identifier (specific details require reference to the manufacturer’s specifications).
3. Key Technical Parameters (Typical Values)
(Actual parameters may vary; consult the manufacturer’s datasheet for confirmation.)

Parameter Typical Value Explanation
Input Speed Up to 4,000 rpm Compatible with high-speed hydraulic/electric motors
Output Torque Range Est. 10,000–25,000 N·m "185" may denote torque class or reduction ratio range
Reduction Ratios 76, 113, 140, 153 (examples) Selectable based on equipment requirements
Brake Type Integrated multi-disc parking brake (optional) Hydraulically released, fail-safe design
Compatible Motors Axial piston motors, orbital motors, electric motors Must match gearbox interface and power specs
Load Capacity Dynamic ≥150 kN, Static ≥300 kN Designed for heavy-duty operations
4. Core Advantages
• High Torque Density:
Achieves compact design with planetary gear architecture, delivering high torque within limited space (e.g., 20,000 N·m output at 100 kW input power).
• Robust Reliability:
• Strengthened main bearing system for high radial/axial loads.
• Mechanical lifetime sealing technology to minimize oil leakage.
• Modular Design:
• Plug-in hydraulic motors(e.g., Bosch Rexroth A2FM series) for simplified installation/maintenance.
• Optional hydraulically released or spring-applied parking brakes to meet safety standards.
• Maintenance-Friendly:
• Quick-disconnect systems: Motor replacement without disassembling the reducer.
• Low-noise gear design: Reduces noise to ≤85 dB through optimized meshing.
5. Selection Guidelines
• Reduction Ratio Selection:
• High ratios (e.g., 153): Ideal for low-speed, high-torque applications (e.g., excavator track drives).
• Low ratios (e.g., 76): Suitable for higher travel speeds (e.g., graders).
• Motor Matching:
• Hydraulic motors: Ensure compatibility with gearbox interface (e.g., Parker F12 series).
• Electric motors: Verify power, speed, and torque curve alignment (e.g., KC45 series motors).
• Environmental Adaptability:
• For extreme temperatures (-30°C to +50°C), select low-temperature grease or high-temperature seals.
6. Common Issues & Troubleshooting
【表格】
Issue Potential Causes Solutions
Overheating Insufficient lubrication or overload Check oil level, replace high-viscosity oil, optimize load distribution
Abnormal noise/vibration Poor gear meshing or bearing damage Adjust gear backlash, replace bearings
Parking brake failure Hydraulic leaks or brake pad wear Inspect hydraulic lines, replace brake pads
