Technical Features
-
Functional Description
The swing motor is the core hydraulic actuator enabling 360° rotation of the excavator's upper structure (cab + boom). Driven by hydraulic oil, its internal gears or pistons generate high torque to rotate the slewing ring smoothly, ensuring precise positioning and efficient operation. -
Working Principle
High-pressure oil from the hydraulic pump enters the motor, rotating the rotor (e.g., axial piston or gerotor assembly). A planetary gear reducer then converts high-speed/low-torque output into low-speed/high-torque force, driving the slewing ring's gear teeth. Cushion valves absorb shock during start/stop, ensuring motion stability. -
Key Roles
- Precision Control: Responds to joystick input for stepless speed adjustment and accurate positioning.
- Power Conversion: Transforms hydraulic energy into mechanical torque to overcome inertia (up to tens of tons).
- Safety Assurance: Integrated brakes and relief valves prevent sliding on slopes or overload damage.
