Field of the Invention The present invention relates to a bearing manufacturing apparatus, and more particularly, to a bearing manufacturing apparatus that exhibits excellent effects in a severe driving environment such as high load conditions, frequent load condition fluctuations, insufficient lubrication conditions, The present invention relates to a bush and a sliding bearing manufacturing apparatus.

Generally, the bearings are moved including friction forces with the pins and the shafts. The bearings are driven by a mechanical element such as a solid lubricant is buried in a pin or a shaft support layer (hereinafter referred to as a slide layer) of the bearing or a lining layer or coating layer of a non-ferrous alloy, ceramic, It is used mainly as a supporting part or sliding part of a device in rotating industrial machine, guide post of a mold, each joint part of a construction machine, etc., and is divided into a bush type (cylindrical type, semi-cylindrical type) and a plate type .

Particularly, the joint part of the rotary machine and the construction machine for high load is driven under the surface pressure of 1.8 MPa ~ 120 MPa when driving, and has a driving condition with a large deviation from 0.2 cm / sec to 10 cm / sec at the driving speed. In addition, it does not have uniform driving load and driving speed, and continuously changes according to the working environment.

However, depending on the shape and material of the supporting structure, dynamic and static pressures depending on sliding, As shown in FIG.

In some cases, a single material may be formed in a plurality of layers.

In order to ensure durability and reduce noise under complex and severe driving conditions, lubrication oil and grease are used to improve the lubrication characteristics, and to collect external impurities, improve durability life, increase the maintenance cycle, and extend lubricant and grease replenishment period. For this reason, various types of pores, grooves or dimples have been used in the slide layer.

However, when the sliding layer of the bearing does not have sufficient supporting ability for the static load, dynamic load, boundary lubrication condition, etc., the load supporting area is reduced by the groove or the dimple to increase the wear amount, Or dimples, it is impossible to collect impurities and the like, so that the foreign matter is mixed with the grease or the lubricant between the sliding layer and the pin or the shaft, and thereby the durability is reduced or the noise is increased, Shorten the Greek supplement period or shorten the replacement period.

In the case of a sliding layer made of a polymer, reinforcing particles or low friction particles are incorporated, or fiber bases are included. However, in order to satisfy the high precision required by the bearing, the post-processing is carried out, The physical properties are significantly reduced.

Therefore, it is difficult to manufacture an integrated bearing which does not break such a sliding layer in a conventional bearing manufacturing apparatus although a bearing formed integrally with the sliding layer is required.

In addition, even if the integrated bearing is produced by the conventional bearing manufacturing apparatus, the bearing can not be separated from the bearing without damaging the shape of the bearing in the bearing manufacturing apparatus.
