Further, in the working process, the inner ring 2 of the bearing rotates with the matched shaft part, so that the ball 3 rotates, abrasion scraps are mainly concentrated in the scraps storage groove 5 of the outer ring 1 under the centrifugal action, and the impurity removing opening is positioned on the outer side surface of the outer ring 1, so that scraps can be cleaned without disassembling the bearing; the impurity outlet 61 of the chip storage groove 5 on the inner ring 2 is positioned on the inner side surface of the inner ring 2 and is contacted with the matched shaft part, and the chip storage groove needs to be disassembled for cleaning, but the chip accumulation is relatively less, so that the cleaning period is longer; through the effect of clean stay cord 62 cooperation cleaning member 63, can realize the clearance to the inside accumulated piece of bearing under the condition that need not wholly decompose the bearing, reduce the degree of difficulty and the time that the bearing was maintained, improved the work efficiency of bearing.
Further, the cleaning member 63 in the chip pocket 5 contacts with the side wall and plays a role of supporting the skeleton in high-strength work, bearing a part of the load of the bearing, and improving the strength of the bearing as a whole.
The front, rear, left, right, up and down are all based on fig. 1 in the drawings of the specification, the face of the device facing the observer is defined as front, the left side of the observer is defined as left, and so on, according to the viewing angle of the person.
In the description of the present application, it should be understood that the terms "center," "longitudinal," "lateral," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like indicate orientations or positional relationships based on the orientation or positional relationships shown in the drawings, merely to facilitate describing the present application and simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and therefore should not be construed as limiting the scope of the present application.
