Bearing system
A bearing and shaft center technology, applied in the field of bearing systems, can solve the problems of increasing the friction coefficient between the shaft sleeve and the shaft center, reducing the service life of the shaft sleeve bearing, and the loss of lubricating oil, so as to prolong the service life, avoid contact friction, reduce friction and reduce friction. The effect of small noise

Example Embodiment
[0010] see figure 1 , The bearing system of the present invention includes a relatively rotatable shaft sleeve 10 , a shaft center 20 and a lubricating layer 22 located between the shaft sleeve 10 and the shaft center 20 .
[0011] The shaft sleeve 10 is installed in a machine body (not shown in the figure), and a desired rotating object (not shown in the figure) is installed on the shaft 20, such as a fan blade, so that the fan blade can rotate around the machine body. The bushing 10 is made of materials with high hardness, such as ceramics, metals, alloys, and the like.
[0012] The shaft 20 can be made of materials with easy surface treatment, such as stainless steel, etc. The shaft 20 is covered with a nano-coating layer 21 on its surface through surface treatment, and the material of the nano-coating layer 21 can be nano-titanium nitride (TiN), Diamond-like carbon (DLC), nano-titanium aluminum nitride (TiAlN), nano-titanium carbonitride (TiCN), nano-chromium nitride (CrN...
