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.
Claims8
A device for manufacturing a wheel bearing assembly, which has a hub provided with one end engaged to a wheel of a vehicle and the other end forming a stepped portion and an end portion, an inner ring mounted on the stepped portion of the hub, an outer ring mounted at a vehicle body, and rolling elements interposed between the outer ring and the hub and the inner ring and orbital-forming the end portion of the hub radially outwardly toward the inner ring, the device comprising:
- a base, on which the 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 the 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.
