Product Description
The swing shaft is a large, robust component that runs horizontally through the center of the excavator's upper structure. Supported by bearings at both ends, it ensures smooth and reliable rotation. One end connects to the swing motor, which generates hydraulic power for rotation, while the other end interfaces with the swing drive mechanism containing gears that convert hydraulic power into mechanical rotation.
Within the swing shaft assembly, the pinion gear (also known as the swing pinion gear or swing pinion shaft) meshes with a larger ring gear attached to the upper structure, enabling precise transmission of swing motion throughout the excavator's operational cycle.
