Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-11, the present invention provides a technical solution: a novel oil inlet ring structure comprises a limiting ring 1, a transition ring 2, an adjusting gasket 6, a spacer ring 7 and a flange plate 8, wherein the limiting ring 1 is arranged in an annular groove of a shaft body, and the whole body and the shaft are kept relatively static to form a whole body; the oil inlet ring assembly 5 is arranged on the excircle surface of the seam allowance of the transition ring 2, when the shaft body rotates, the oil inlet ring assembly 5 keeps still, and the contact surface of the oil inlet ring assembly 5 and the whole structure is in a relative sliding state. For direct and the axis body contact of oil feed ring, relative slip causes wearing and tearing to the axis body, this structure only oil feed ring subassembly and transition ring relative slip, only need change after the wearing and tearing the transition ring can, greatly reduced the later maintenance cost.

The oil inlet ring assembly 5 comprises an oil inlet ring 12, a copper sleeve A13 and a copper sleeve B14 which are connected through screws; the pin 15 is respectively connected between the oil inlet ring 12 and the copper bush A13 and the copper bush B14 to realize the positioning function; according to the oil inlet ring assembly structure, only two copper sleeves are made of copper alloy materials, and compared with an integral oil inlet ring, the oil inlet ring assembly structure is made of copper alloy materials, so that the material cost is greatly reduced.

2 limiting rings 1 are respectively installed in the annular grooves of the shaft bodies on two sides to realize axial positioning of the oil inlet ring, and the adjusting gasket 6 is used for adjusting the axial installation gap of the oil inlet ring.

The oil inlet ring assembly 5 is connected with the end cover 3 and the pressure plate 4 through screws, the rotary lip seal 9 of the inner wrapping framework is arranged among the end cover, the pressure plate and the transition ring, and the oil inlet ring assembly can still play a role in sealing after the side oil way seal fails and is convenient for replacing the seal.
