Hitachi Excavator Parts Swing Drive Motor ZX240-3 M5X130 4625367 For Excavator Spare Parts

Hitachi Excavator Parts Swing drive Motor ZX240-3 M5X130 4625367 for excavator spare parts

The excavator swing motor is one of the core components in the hydraulic system of an excavator, primarily responsible for driving the upper structure (including the cab, boom, arm, etc.) to rotate 360 degrees. The performance of the swing motor directly affects the operational flexibility and work efficiency of the excavator.

Hydraulic Drive Principle

The swing motor is driven by high-pressure hydraulic oil provided by the hydraulic system. When the operator manipulates the control lever, the hydraulic pump delivers high-pressure oil to the inlet of the swing motor, pushing the internal rotor to rotate. The rotation of the rotor is transmitted through the reduction mechanism to the swing bearing, thereby driving the upper structure of the excavator to rotate.

Structural Composition

The swing motor typically consists of the following main parts:

• Hydraulic Motor: Converts hydraulic energy into mechanical energy, driving the rotor to rotate.

• Reduction Mechanism: Reduces speed and increases torque, ensuring smooth and powerful swing motion.

• Swing Bearing: Connects the upper structure and the lower chassis, bearing the load during rotation.

• Brake System: Prevents the upper structure from continuing to rotate due to inertia when the operation stops, ensuring safety.
