Self-lubricating rolling bearing

Abstract

The invention discloses a self-lubricating rolling bearing. The self-lubricating rolling bearing comprises a bearing inner ring (3), a bearing outer ring (1) and a rolling body (2); the bearing inner ring (3) is arranged in the bearing outer ring (1); the rolling body (2) is arranged between the bearing inner ring (3) and the bearing outer ring (1); a hole assembly (11) comprises a guide hole (111) and a through hole (112); the guide hole (111) is formed in the side wall of the bearing outer ring (1); the through hole (112) is formed along the radial direction of the bearing outer ring (1); and the through hole (112) is connected with the area of the guide hole (111), the bearing inner ring (3) and the bearing outer ring (1). The self-lubricating rolling bearing can prolong the lubricating time and enhance the flowability of lubricating oil so as to prolong the service life of a bearing.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a self-lubricating rolling bearing. Background technique [0002] Oil bath lubrication is the most common lubrication method for rolling bearings. It is suitable for the lubrication of low-speed bearings. During the lubrication process of rolling bearings, the bearing part is soaked in the lubricating oil in the oil tank. The lubricating oil is carried by the rotating bearing parts and then flows back into the oil tank. . However, in the prior art, for the installation method in which the inner ring of the bearing is fixed and the outer ring rotates, the outer ring of the bearing rotates out of the lubricating oil in the oil groove and quickly flows back into the oil groove, causing the outer ring of the bearing to be in an environment with insufficient lubrication. It is easy to aggravate the wear of the outer ring of the bearing and the rolling elements, reducing the service ...
