Problems solved by technology
However, the bonding between the coating layer and the alloy steel is difficult, the processing technology is relatively complicated, and the coating uniformity and bonding strength are strictly required.
Moreover, the coating layer is easy to wear, and the occlusal surface may be seized, which in turn causes damage to the bearing and cannot be disassembled and replaced, shortening the service life

Embodiment Construction
[0019] Please refer to Figure 1 to Figure 4 , this embodiment discloses a female bearing bush 100, which includes a main body 1 made of ninety-four copper, and several seals 2 and lubricants (not shown) respectively arranged in the main body 1 . The main body 1 is in the shape of a hollow shaft and includes an inner wall 11 and an outer wall 12 . The inner wall 11 is recessed with at least two sealing grooves 111 for respectively accommodating the sealing elements 2 , and the inner wall 11 is also recessed with an oiling groove 112 located between the sealing grooves 111 and containing lubricant.
[0020] The main body 1 is made of ninety-four copper, which is the standard brand of ninety-four copper used in this embodiment. The ninety-four copper is aluminum bronze, and the content is as follows: aluminum 8%-10%, iron 2%-4%, zinc <1% , tin <0.1%, manganese <0.5%, lead <0.01%, impurities <1.7% (except copper, aluminum and iron are all impurities), and the copper balance is g...

The invention discloses a female bearing bush and a bearing. The female bearing bush comprises a main body made of 94 percent copper, a plurality of sealing elements respectively arranged on the main body and a lubricating agent, wherein the main body is in a hollow shaft shape and comprises an inner wall and an outer wall; the inner wall is concavely provided with at least two sealing grooves for respectively accommodating the sealing elements; the inner wall is also concavely provided with an oiling groove which is positioned between the sealing groove and used for accommodating the lubricating agent, so that the female bearing bush is not required to be coated with a nonmetallic abrasion-resistant macromolecular material; and because the lubricating agent plays a role in lubricating, the female bearing bush is difficult to abrade and can be prevented from being locked when the female bearing bush is engaged with a male bearing bush, and the female bearing bush and the bearing are relatively easy to process and have relatively long service life.
Description
【Technical field】 [0001] The invention relates to a female bearing bush and a bearing. 【Background technique】 [0002] At present, the commonly used female bearing bush is generally made of alloy steel, which includes an outer ring and an inner ring. The inner ring of the female bearing bush is coated with a layer of non-metallic wear-resistant polymer material to make it elastic to engage with the male bearing bush. However, the bonding between the coating layer and alloy steel is relatively difficult, and the processing technology is relatively complicated, and the requirements for uniformity of coating and bonding strength are strict. Moreover, the coating layer is easy to wear, and the occlusal surface may be seized, which in turn causes the bearing to be damaged and cannot be disassembled and replaced, and the service life is shortened. 【Content of invention】 [0003] Based on this, it is necessary to provide a female bearing bush and a bearing which are easier to p...
