Komatsu excavator parts E325C 227-6116 travel Reduction Gearbox for belparts hydraulic spare parts

The excavator travel gearbox (also known as the walking gearbox or track drive gearbox) is a critical component in crawler excavators, responsible for transferring power from the engine to the tracks, enabling controlled movement. Designed to withstand heavy loads and harsh environments, it ensures efficient mobility across diverse terrains. This guide explores its working principles, construction, functions, applications, and maintenance practices.

Product Description

List of spare parts

The excavator travel gearbox (also known as the final drive or track gearbox) is a vital component in an excavator’s undercarriage system. It serves as the critical link between the hydraulic motor and the tracks, converting high-speed, low-torque input into low-speed, high-torque output to ensure smooth and powerful movement across challenging terrains.

Structure & Working Principle

The travel gearbox typically consists of:

• Gear Train: Helical or planetary gears for high load capacity and reduced noise.

• Housing: Durable cast iron or aluminum alloy for protection and heat dissipation.

• Bearings & Seals: Precision bearings for smooth rotation and multi-layered seals to prevent contamination.

• Braking Mechanism: Integrated wet or dry brakes for enhanced safety.

Power flows from the hydraulic motor into the gearbox, where multiple gear stages reduce speed while multiplying torque, enabling the excavator to move efficiently even under heavy loads.
