The purpose of this utility model and effect are reached by technical solution in detail below：
A kind of motor drive shaft cored structure of cpu fan, including：Shaft ontology, tooth socket, flat key, axial trough, spindle nose；Described turn
Tooth socket is provided on the left of shaft body, and shaft ontology is an integral structure with tooth socket；The flat key is arranged on shaft ontology
Left upper portion, and flat key is an integral structure with shaft ontology；The spindle nose is arranged on one end of shaft ontology, and spindle nose is with turning
Shaft body is connected by axial trough.
Preferably, the shaft ontology is an integral structure with spindle nose by lathe tool processing sets up, and on the right side of shaft ontology
End face week be provided with the chamfering of 0.2mm.
Preferably, the surface of tooth socket mode arranged in a ring is provided with five to seven places and baroclines colored tooth, and gullet surface
Colored tooth depth of baroclining less than 0.23mm.
Preferably, the flat key height is less than the level height of shaft ontology.
Preferably, the spindle nose is round table-like, and the top of spindle nose is provided with transition arc.
Due to the utilization of above-mentioned technical proposal, the utility model has following advantages compared with prior art：
1st, the utility model is by setting tooth socket, and the design structure being connected using the colored tooth that baroclines with power plant makes this
The connectivity robustness of device is strong, effectively improves the degree of operating steadily of the device.
2nd, the utility model, using the mating connection of flat key and fan blade, has the device by setting flat key
It effectively prevent the advantages of idle running problem occur during blade rotating operation.
3rd, the utility model has overall construction design reasonable, convenient for Fast Installation and operation by the improvement in structure
Precision height reduces operation noise, and external impetus connectivity robustness is strong, effectively improves fan degree of operating steadily and has slide system work(
The advantages that energy, so as to effectively solve the problems, such as existing apparatus and deficiency.
