[0002] A floating bearing (or floating bearing system) is a type of bearing commonly used in mechanical engineering, characterized by the fact that the bearing itself is not completely fixed on the housing or support structure, but can move or float within a certain range. This design allows the floating bearing to adapt to the small displacement between the shaft and the bearing, thereby improving the running accuracy and stability of the mechanical system.

[0003] Referring to the patent document CN219432287U floating bearing lubrication structure, including bearing cover, the outer side of the bearing cover is provided with an outer oil groove, the outer side of the bearing cover is provided with an outer oil port at the middle position of the outer oil groove, the inner side of the bearing cover is fixedly connected with a bearing body, the outer side of the bearing body is provided with an inner oil port, the inner side of the bearing body is provided with an inner oil groove, the inner side of the bearing body is provided with an inner circular oil groove at the middle position, through the setting of the outer oil groove, the inner oil groove and the inner circular oil groove, when the floating bearing follows the rotating shaft, the lubricating oil will directly enter the outer oil groove, and the excess part will flow through the outer oil groove, at the same time, the lubricating oil will enter the bearing body through the inner oil groove, and then the lubricating oil will flow in the bearing body along the inner circular oil groove, therefore, the structure setting is convenient for the lubricating oil to enter the floating bearing, therefore, the lubrication effect is improved.

[0004] The above scheme can add lubricant during use, but still has some deficiencies during use, for example, when adding lubricant, the outer oil groove is full type, which causes the lubricating oil to be quickly lost during use, and it is difficult to discharge the used lubricating oil, the lubrication effect of the waste lubricating oil is reduced, and the wear resistance of the bearing is affected.

[0005] Therefore, we propose a full-floating bearing anti-wear damping structure to solve the above problems. CONTENT OF THE UTILITY MODEL
