This gear processing mechanism operates on the outer circumference of the outer ring, which functions as both a bearing ring and a driving gear ring. In this design, the driving small gear engages with the outer teeth of the outer ring to facilitate the transmission of rotational power. As the small gear rotates, it drives the outer ring, which is connected to the upper structure (such as the upper frame of an excavator), allowing for efficient rotational movement. Typically, the inner ring is fixed to the base or frame, ensuring optimal stability. The innovative design features steel balls with four-point contact along the inner and outer ring raceways, enabling the simultaneous handling of axial loads, radial loads, and overturning moments. This combination meets the diverse demands of mixed force conditions. With its compact structure, composite load-bearing capabilities, and efficient active transmission, this product is ideal for the power rotation needs of medium and light equipment.
