Fig. 3 is a schematic structural diagram of a housing and a bearing seat according to another exemplary embodiment of the present disclosure. Fig. 4 is an enlarged schematic view of B in fig. 3. As shown in fig. 2 to 4, the first end surface 111 and the second end surface 112 of the bearing housing 110 are located at both ends of the bearing housing 110 in the axial direction, respectively, and it should be understood that the bearing is located between the first end surface 111 and the second end surface 112 after the bearing is assembled in the bearing housing 110.
Correspondingly, the communication position of the first end 121 of the glue injection channel 120 and the bearing chamber 110 is located between the first end surface 111 of the bearing chamber 110 and the second end surface 112 of the bearing chamber 110, so that after glue is injected into the glue injection channel 120, the glue flowing into the bearing chamber 110 from the first end 121 of the glue injection channel 120 is distributed on the outer side wall of the bearing and does not easily reach the two side edges in the axial direction of the bearing, thereby effectively preventing the glue from entering the inside of the bearing from the two side edges in the axial direction of the bearing, reducing the influence of the glue on the rolling bodies in the bearing, and prolonging the service life of the bearing.
According to the bearing seat 100 and the fan provided by the embodiment of the application, the bearing is assembled through the bearing chamber 110, and the glue injection channel 120 communicated with the bearing chamber 110 is arranged, so that after the bearing is installed in the bearing chamber 110, anaerobic glue is injected through the glue injection channel 120, and therefore after the bearing is installed in the bearing chamber 110, the position of the bearing in the bearing chamber 110 can be adjusted according to the assembly requirement, the coaxiality of the assembled bearing and the bearing chamber 110 is effectively improved, and the risks that abnormal sound occurs and the rotating efficiency of a rotor shaft is influenced due to large coaxiality deviation in the follow-up process are reduced; in addition, the communication position between the first end 121 of the glue injection channel 120 and the bearing chamber 110 is arranged between the first end surface 111 and the second end surface 112, so that after glue is injected into the glue injection channel 120, the glue flowing into the bearing chamber 110 from the first end 121 of the glue injection channel 120 is distributed on the outer side wall of the bearing and does not easily reach the two side edges in the axial direction of the bearing, thereby effectively preventing the glue from entering the inside of the bearing from the two side edges in the axial direction of the bearing, reducing the influence of the glue on the rolling body in the bearing, and prolonging the service life of the bearing.
As shown in fig. 2 to 4, the inner wall of the bearing chamber 110 is recessed with a glue receiving groove 160, and the first end 121 of the glue injection channel 120 extends into the glue receiving groove 160. Like this, after injecting glue into injecting glue passageway 120, the glue that flows out from first end 121 of injecting glue passageway 120 will enter into and hold gluey groove 160, holds gluey groove 160 and can be used for holding glue, promotes the glue volume between bearing and the bearing room 110, treats the glue solidification back in holding gluey groove 160, can make and be connected more firmly between bearing and the bearing frame 100.
As shown in fig. 4, in an embodiment, the glue containing groove 160 is an annular groove, so that the glue entering the glue containing groove 160 can flow in the glue containing groove 160, so that the glue can be distributed on different parts of the outer wall of the bearing, and after the glue on different parts of the outer wall of the bearing is solidified, different parts of the outer wall of the bearing can be tightly connected with the inner wall of the bearing chamber 110, thereby effectively improving the connection stability between the bearing and the bearing seat 100.
