[0002] A bearing cage is a bearing component that partially wraps all or part of the rolling elements and moves with them to isolate the rolling elements and usually guide the rolling elements and keep them in the bearing.

[0003] At present, the existing traditional cylindrical roller bearing cage does not have the function of self-lubrication, and it is necessary to manually lubricate the bearing with lubricating oil. However, manual lubrication is not only time-consuming and labor-intensive, but also cannot effectively lubricate the bearing, and causes a certain amount of waste of lubricating oil. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a self-lubricating bearing retainer.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] Furthermore, a plurality of overflow grooves are provided on the circumference of the bearing retainer body, and the overflow grooves are connected with the annular groove and the clamping groove.

[0010] Furthermore, a plurality of the overflow troughs are distributed in a circular array.

[0011] The beneficial effects of the utility model are:

[0012] 1. The lubricating oil in the oil storage chamber is input into the oil outlet hole through the main oil pipe and the diverter pipe, and then discharged into the card slot from the oil outlet hole, so as to automatically lubricate the cylindrical roller, which saves time and effort, is convenient and fast.

[0013] 2. Through the setting of the overflow groove and the annular groove, when the lubricating oil in one of the grooves is filled, it flows into other grooves through the overflow groove and the annular groove, so as to evenly lubricate the cylindrical roller and improve the lubrication effect.
