▎ 摘　　要

NOVELTY - The assembly has a coaxial axis (02), a bearing (03) and a shaft tube that are provided together. The inner space of the shaft tube is provided with a bearing. The inner space of the bearing is provided with an axis. The portion of the inner wall surface of the bearing or portion of the outer surface of the axis is formed with a diamond-like carbon plating layer or a graphene adhesion layer. The diamond-like carbon plating layer or graphene adhesion layer is formed on the surface where the bearing and the axis contact each other. USE - Fan assembly of fan (claimed). ADVANTAGE - The bearing is provided with the solid lubricating effect of diamond-like carbon plating layer through the friction structure axis, so as to effectively improve the dispersion for lubricating grease and other auxiliary material. The device is featured with higher practicability, convenient use and safety. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a fan. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the fan assembly. Coaxial axis (02) Bearing (03) Stator (04) Magnet group (05) End cover (06)
