Hitachi excavator M5X130CHB-10A-50A300 ZX670 4651137 Swing gearbox motor assembly

The swing motor typically consists of three main parts:

1. Hydraulic motor unit: Converts hydraulic energy into mechanical energy to provide rotation torque

2. Braking system: Includes mechanical brake and hydraulic release brake to ensure parking positioning

3. Planetary reduction gear: Reduces speed and increases output torque

Working principle: Pressure oil drives the hydraulic motor to rotate, which then drives the swing bearing through the planetary reducer to rotate the upper platform.

Technical Features

1. High torque density design - compact size with large output torque

2. Integrated multi-disc brake - reliable and smooth braking

3. Axial piston structure - high efficiency and long service life

4. Excellent speed regulation performance - enables stepless speed control

5. Built-in relief valve and replenishing valve - protects system safety
