Problems solved by technology

[0008] However, according to the conventional sliding bearing 1 as described above, the radial oil grooves 4 formed on the upper friction surface 3a of the frame 3 do not communicate with the spiral oil grooves 5 formed on both side friction surfaces 3b, and thus the An adequate lubricant film does not form around frame 3

Abstract

A slide bearing is provided, which includes a frame 3 having a structure formed in one direction thereof to be coupled to a rotation shaft, an external radial friction surface 3c and two longitudinal friction surfaces 3d with oil grooves 11a and 12a formed thereon. Since oil paths 11 and 12 formed on the external radial friction surface 3c and the longitudinal friction surfaces 3d, respectively, by the oil grooves 11a and 12a for the flow of lubricating oil, oil grooves 11a of the oil path 11 and the are oil grooves 12a of the oil path 12 are formed repeatedly at predetermined intervals, wherein the edges of the external radial friction surface 3c and the longitudinal friction surfaces 3d communicate with each other so as to enable the lubricating oil to flow. According to the slide bearing, a sufficient lubricant film can be formed around the frame that is in contact with the corresponding part of the bearing support.

Description

technical field [0001] The present invention relates to sliding bearings, and in particular to a sliding bearing capable of providing stable lubrication between a sliding bearing fixed in a body to a rotating shaft (or journal) and a corresponding bearing bracket rotatably housing the sliding bearing The agent film ensures smooth rotation of the rotating shaft about the sliding bearing and reduces frictional noise between the sliding bearing of the rotating shaft and the bearing bracket. Background technique [0002] In general, a bearing is one of mechanical parts, and is an element that bears the load of a corresponding element that rotates or reciprocates, such as a shaft, a shaft, a journal, and rotatably supports a shaft. [0003] Such as Figures 1 to 3 As shown, a conventional sliding bearing 1 is mainly composed of an assembly part 2 and a frame 3, the assembly part 2 is located on the inner side and integrally fixed to a corresponding connection part of the rotating...
