Description
Technical Field
[0001] The utility model belongs to the technical field of mechanical equipment, and in particular relates to a supporting transmission structure for mechanical equipment. Background Art
[0002] Sliding bearings have the advantages of stable operation, low noise and long life. In order to enable the sliding bearings to normally play their supporting and transmission functions, the sliding bearings are usually installed in the bearing seats. The connection between some existing sliding bearings and the bearing seats is a fixed connection, which is not convenient for disassembly. When the sliding bearings are severely worn due to long-term use and cannot be used, in order to make the mechanical equipment operate normally, the damaged sliding bearings need to be replaced. Since the connection between the sliding bearings and the bearing seats is difficult to disassemble, the bearing seats are passively replaced together, which wastes materials and has a high economic cost.

[0084] Both ends of the convex ridge 8 widen and extend into the opening 13 to form two operating handles 11 .
[0085] The operating handle 11 is provided with a through hole 12
[0086] In the present embodiment 10, a through hole 12 is provided on the operating handle 11. When it is necessary to remove the retaining ring 3 between the sliding bearing and the bearing seat, the through hole 12 allows the operating handle 11 to be better stressed. When in use, the retaining ring 3 can be pulled out as a whole by fingers, or the retaining ring 3 can be removed as a whole from between the bearing seat and the sliding bearing by using a hook tool. When using the hook tool, the hook of the hook tool is passed through the through hole 12, and then the hook tool is pulled up, so that the retaining ring 3 is separated from between the sliding bearing and the bearing seat under the pulling of the hook tool.
[0087] The bearing seat 1 comprises a mounting seat 25 and a handle 26 which are integrally connected. The mounting through hole 4 is formed on the mounting seat 25 , and a threaded blind hole 27 is formed on one end of the handle 26 away from the mounting seat 25 .
