A support (10) for a spherical bearing includes a substantially annular ring (12) defining an axial facing abutment surface (14) and an inside surface (16). The inside surface (16) is sloped radially outward toward the abutment surface (14). The annular ring (12) has an outer circumferential surface (20) that has a locking mechanism (18) thereon. The support (10) can be secured substantially between axial ends of the spherical bearing (22). The support (10) limits axial movement of an inner race (24) defined by the spherical bearing (22).

摘要:
The invention refers to a spherical bearing (10). The spherical bearing has an inner ring at least partially disposed within an outer ring (70). A first end of the outer ring (70) has an external threaded area (75) having at least two first grooves (84) formed therein. The first grooves (74, 84) are asymmetrically positioned. The spherical bearing (10) includes further an annular nut (60) having an internal thread and a plurality of notches (62) formed in an outer circumferential portion of the nut (60), the notches being axially oriented. The spherical bearing (10) further includes a washer (40) having an annular body (40A) defining a radially outer circumferential edge (12) and a radially inner circumferential edge (14) defining an opening. The threaded area (75) is positioned in the opening of the washer. The annular body (40A) has a first planar surface (22) on one axial end thereof and a second planar surface (32) on an opposing axial end of the annular body. The outer circumferential edge (12) has a plurality of first tabs (42) extending therefrom and in a direction away from the first planar surface (22) and the outer circumferential edge (12). The inner circumferential edge (14) has at least two second tabs (50) extending therefrom and in a direction axially away from the first planar surface (22), the second tabs (50) being circumferentially aligned with and positioned in the first grooves (84). Each of the first tabs (42) are selectively bendable for engagement with one of the notches (62). There are at least one more first tabs (42) than notches (62).

The present invention relates to a structure and a method for coupling a wheel bearing that include a wheel hub for mounting a vehicle wheel, a hollow inner ring press-fitted into an end portion of the wheel hub, an annular outer ring disposed at a radial exterior of the wheel hub and the inner ring, and rolling elements disposed between the wheel hub or the inner ring and the outer ring, wherein the wheel hub and the inner ring are splined to each other and the inner ring and the joint member are coupled through facial spline. According to the present invention, driving torque of a constant velocity joint may be stably delivered to the wheel hub and noise may be reduced.
