Abstract

The invention discloses a special-shaped bearing and a special-shaped bearing structure. The special-shaped bearing comprises a fan blade, the bottom of the fan blade is fixedly connected with a motorshell, the outer wall of the motor shell is fixedly connected with a magnet, the interior of the fan blade is fixedly connected with a shaft core, the outer wall of the shaft core is movably connected with the special-shaped bearing, the interior of the special-shaped bearing is provided with an oil storage groove, and the top of the special-shaped bearing is fixedly connected with a buckle ring;and the top of the buckle ring is fixedly connected with a positioning ring, the bottom of the special-shaped bearing is fixedly connected with a wear plate, the bottom of the wear plate is fixedly connected with a copper middle tube, one side of the copper middle tube is fixedly connected with a shooting stator, the bottom of the shooting stator is fixedly connected with a PCB board, the bottomof the PCB board is fixedly connected with a base, and the top of the base is fixedly connected with an upper cover. According to the special-shaped bearing and the special-shaped bearing structure, the oil storage inside the bearing is increased, the lubrication time is improved, the contact area between the bearing and the shaft core is reduced, the friction is reduced, the service life of the fan is prolonged, and the sound quality of a fan is improved.

Description

technical field [0001] The invention relates to the technical field of special-shaped bearings, in particular to special-shaped bearings and special-shaped bearing structures. Background technique [0002] Bearing is an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Special-shaped bearings include inner hexagonal bearings. The difference is that the inner hole of ordinary bearings is It is round, and the inner hole of special-shaped bearings is non-circular. Oil bearings, that is, porous bearings, use metal powder as the main raw material. Oil bearings are sintered bodies made by powder metallurgy. The technical advantages such as the number, size, shape and distribution of pores can be adjusted freely during the process. [0003] At present, some traditional oil-impregnated bearings and traditional oil-impregnated bearin...
