Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the predetermined purpose, the following detailed description of the sliding bearing assembly according to the present invention with reference to the accompanying drawings and preferred embodiments will be made below.

In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", and the like indicate orientations or positional relationships based on the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.

Referring to fig. 1 to 9, the sliding bearing assembly of the present embodiment includes a bearing seat 1, a bearing cap 2 mounted on the bearing seat 1, and a journal 3, wherein the journal 3 is sleeved with a plurality of bearing pads 4 along an axial direction, the bearing cap 2 is mounted on the bearing seat 1 by means of bolt connection or adhesion, a plurality of concave second raceways 9 are respectively disposed on inner surfaces of the bearing seat 1 and the bearing cap 2 along the axial direction, and when the bearing cap 2 is mounted on the bearing seat 1, the second raceway 9 on the bearing seat 1 and the second raceway 9 on the bearing cap 2 form an annular raceway.

When the bearing cover 2 is arranged on the bearing seat 1, a plurality of bearing bushes 4 are arranged in a cavity formed by the bearing cover 2 and the bearing seat 1 along the axial direction, and the bearing bushes 4 are sleeved on the journal 3; a plurality of concave first roller paths 8 are arranged on the outer surface of the journal 3 along the axial direction; the bearing bush 4 comprises a support ring 5, the outer surface of the support ring 5 is provided with a first convex spherical surface 6 matched with a second raceway 9, and the inner surface of the support ring is provided with a second convex spherical surface 7 matched with a first raceway 8; the first convex spherical surface 6 of the bearing shell 4 is mounted in the second raceway 9, while the second convex spherical surface 7 of the bearing shell 4 is mounted in the first raceway 8, the bearing shell 4 being bonded to the journal 3.

For the convenience of installation, in the present embodiment, the bearing shell 4 is of a split structure, i.e., the bearing shell 4 includes an upper bearing shell and a lower bearing shell. The upper bearing bush is arranged in the bearing cover 2, and the lower bearing bush is arranged in the bearing block 1; in order to ensure the bearing capacity, the bearing bush is made of materials with high wear resistance, high hardness and high strength.

In this embodiment, a solid lubrication manner is adopted between the first convex spherical surface 6 and the second raceway 9, and between the second convex spherical surface 7 and the first raceway 8, and oil solid lubricants are coated on the surfaces of the first raceway 8 and the second raceway 9; of course, in other embodiments of the present invention, an oil lubrication method may also be adopted, that is, an oil groove is processed on the bearing cap 2, and then the lubricating oil is injected into the oil groove.

The contact surface of the first convex spherical surface 6 and the second raceway 9 and the contact surface of the second convex spherical surface 7 and the first raceway 8 are both coated with high-wear-resistance materials.

Compared with the traditional sliding bearing, the sliding bearing assembly in the embodiment has the advantages of small starting friction moment, simple structure, convenience in maintenance and high transmission efficiency, and shaft sleeve parts in the sliding bearing are also omitted.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and any person skilled in the art can make any simple modification, equivalent change and modification to the above embodiments according to the technical spirit of the present invention without departing from the technical scope of the present invention.
