Embodiment Construction
[0013] The present invention will be further described below in conjunction with the accompanying drawings.
[0014] refer to Figure 1 ~ Figure 3 , a ceramic bearing, including an outer ring 1 and an inner ring 2, the inner ring 2 is nested in the outer ring 1, the inner hole of the outer ring 1 is an inverse spherical surface, and the outer surface of the inner ring 2 is a conical surface , the inclination angle of the tapered surface is 5-10°, and the centerline of the inner hole of the outer ring 1 is in contact with the neutral line of the outer side of the inner ring 2 .
[0015] Further, the inclination angle of the tapered surface is 6-8°.
[0016] In this embodiment, the shape of the inner hole of the outer ring (anti-spherical surface) and the shape of the outer diameter of the inner ring (conical surface) are changed to reduce friction, facilitate processing and withstand axial force.
[0017] In this embodiment, nano ceramic materials are preferably used.
