Abstract
The present invention relates to device and method for manufacturing a wheel bearing assembly that reduces an error rate by reducing stress concentrated on rolling elements in manufacturing processes of the wheel bearing assembly. The device for manufacturing a wheel bearing assembly may include: a base, on which a hub is mounted, supporting the hub in a case of orbital-forming; a forming tool mounting portion mounted above the base; a rotating portion rotatably connected to an outer ring and rotating or pivoting the outer ring about a hub axis in a case of the orbital-forming; and a forming tool mounted at the forming tool mounting portion, rotating on a first axis slanted to the hub axis by a predetermined angle, and simultaneously orbiting about a second axis parallel with the hub axis.
