Referring to fig. 1 to 3, the utility model discloses a cooling fan for a bearing on a rotating shaft, which comprises an annular chassis 10; the annular chassis 10 comprises two semi-annular bodies 11 separable from each other; the two disc bodies 11 are matched with the rotating shaft 100 of the first enclasping piece 20; each tray body 11 extends downwards to form a semi-annular first enclasping piece 20; the opposite sides of each first enclasping piece 20 extend outwards to form first fan blades 30 fixed on the corresponding disc body 11; the two first fan blades 30 on opposite sides of the two first hugging members 20 are fixedly connected through a first screw structure 40, so as to prevent the two first hugging members 20 from being separated.

On the basis of the structure, when the disc bodies 11 are assembled, the two separated disc bodies 11 are separated at two sides of the rotating shaft 100 and are abutted together, at the moment, the two first enclasping members 20 are abutted against the rotating shaft 100, and then the two opposite first fan blades 30 are fixed by adopting the first screw structure 40 to prevent the two disc bodies 11 from being separated, namely the two first enclasping members 20 are prevented from being separated along with the disc bodies 11 to protect the enclasping rotating shaft 100, so that quick installation is realized; when the cooling fan is used, the air outlet direction of the cooling fan for the bearing on the rotating shaft faces the bearing, and the rotating shaft 100 drives the first fan blade 30 to rotate to realize air outlet to the bearing, so that the bearing is cooled.

It should be noted that, in the present embodiment, the first screw structure 40 is used to fix the two first fan blades 30, and the mounting plate 90 connected with the first enclasping member 20 is not required to be additionally arranged for fixing the first screw structure 40, so that the components are saved and the structure is simplified.

The bottom surface of each tray body 11 of this embodiment is fixed with a plurality of second fan blades 50, and the plurality of second fan blades 50 are disposed between two corresponding first fan blades 30 at intervals, so that the first fan blades 30 and the second fan blades 50 cooperate to generate wind, which can increase the wind volume and improve the heat dissipation efficiency.

The second fan blade 50 of the present embodiment is further fixed on the corresponding first enclasping member 20, so as to strengthen the strength of the second fan blade 50.

It should be noted that the spacing between any adjacent first fan blade 30 and second fan blade 50 and any adjacent second fan blade 50 is equal.

The outer side of the first fan blade 30 of the present embodiment extends to a position flush with the outer side surface of the disk 11, so that the area of the first fan blade 30 is maximized without enlarging the radial width of the heat radiation fan for the bearing on the rotation shaft.

In this embodiment, the outer side of the second fan blade 50 may also be extended to a position flush with the outer side surface of the disk 11.

The tray body 11 in this embodiment gradually inclines upwards from the inner side to the outer side thereof, so as to guide the wind direction generated by the first fan blade 30 and/or the second fan blade 50 upwards, and the wind outlet direction is upward when the rotating shaft 100 rotates forward or backward, so that the practicability is stronger.

Each tray 11 is in a downward protruding arc shape to achieve a better wind guiding effect.
