This application discloses an assembled ball cage cage, employing a modular, split-type architecture. It includes multiple cage units and two sets of retaining rings. Each cage unit is circumferentially assembled to form a cage body with concentric inner and outer spherical surfaces. The cage body has circumferentially distributed openings. The retaining rings achieve axial positioning and locking of the cage body. After connecting to the cage body, the end face of the
retaining ring is parallel to the long side of the opening. Through the combination of multiple cage units and two sets of retaining rings, the
modular design allows for the replacement of only damaged cage units, reducing maintenance costs. The cage units can be
mass-produced, further reducing manufacturing costs. The assembled units form precise concentric spherical surfaces, ensuring the stability of the
steel ball's trajectory and reducing vibration and
noise. The
parallel design of the retaining rings to the end face of the cage body ensures uniform force distribution on the long side of the opening, avoiding increased friction due to axial misalignment. By replacing individual units, the overall service life of the cage is extended.
