Abstract：
 The present invention is a non-contact sealing structure for a rotary gear box. According to the rotary gear box, it can be lubricated by watery oil and will not appear the problem of oil leakage, and has better lubricant effect. The structure includes a rotary gear box which is mounted on the external part of a central shaft and is mounted with a gear derive structure therein. The driven output gear in the gear drive structure is connected with the gear box. The combine places of the two ends of the gear box and the central shaft and the central shaft are respectively enclosed with bearings. It is characterized in that the periphery of the inner end surface of the gear box is disposed with an oil block sleeve and an oil direct groove, the end surfaces of the inside of the bearings are respectively disposed with oil blocking shoulders; the combine places between the gear drive structure and the central shaft are respectively disposed with bearings, the lubricant will flow to the outside along one side of the central shaft through the bearings, the drive structure is disposed with oil return holes therein.
