Roller bearing with microstructures on surfaces of roller ways and lubricating method of roller bearing

[0029] Example 1

[0030] See Figure 1-3 , The roller bearing with a micro-textured raceway surface in this embodiment includes a bearing inner ring 1, a bearing outer ring 2, and a rolling element 3 arranged between the bearing inner ring 1 and the bearing outer ring 2; wherein, The raceway surface of the bearing inner ring 1 and the raceway surface of the bearing outer ring 2 are both provided with a reinforced abrasive layer, and the surface of the reinforced abrasive layer is provided with a micro-textured structure; the micro-textured structure consists of multiple edges The vertical strip-shaped grooves 4 uniformly arranged in the circumferential direction are formed, and the extending direction of the vertical strip-shaped grooves 4 is parallel to the axial direction of the bearing.

[0031] See Figure 1-3 The cross section of the vertical strip-shaped groove 4 is "V" shaped.

[0032] See Figure 4-6 , F 1 , F 2 Is the contact stress of the "V"-shaped groove, and the magnitude

[0054] Example 2

[0055] In a preferred solution of the present invention, the cross section of the vertical strip-shaped groove 4 is an arc, and the arc is an inferior arc.

[0056] Further, the cross section of the vertical strip-shaped groove 4 may be a circular arc shape, an elliptical arc shape, a parabolic shape or other high-order curved arc shapes.
