[0006] When a ball bearing is installed in the bearing installation inner cavity, the ball bearing is installed through a bearing sleeve sleeved on the outer side thereof.

[0007] The universal bracket bodies corresponding to the two bearings have the same appearance and structure, and both have bearing installation cavities. They can be formed using the same mold. It is only necessary to replace different mold cores. One set of molds can form the universal bracket bodies corresponding to the two bearings, which is very convenient.

[0008] Preferably, a positioning groove is provided on the outer side of the tapered bearing chamber, and the wool felt is embedded and installed in the positioning groove to limit the wool felt. The wool felt absorbs a lot of lubricating oil, and the lubricating oil can continuously enter the tapered bearing chamber.

[0009] Preferably, a limiting groove engaged with the pressing plate is provided in the middle of the bearing installation cavity to facilitate positioning of the pressing plate.

[0010] Preferably, a plum blossom-shaped through hole matching the oil-containing bearing is provided in the middle of the pressing sheet, which is conducive to limiting the oil-containing bearing.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The universal bracket bodies corresponding to the two bearings have the same appearance and structure, and both have an inner cavity for bearing installation. They can be formed using the same mold. Only different mold cores need to be replaced. One set of molds can form the universal bracket bodies corresponding to the two bearings, which can reduce mold investment costs, reduce mold change times, reduce mold change time, and improve production efficiency.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] like Figure 1-8 As shown, the utility model provides a universal bearing bracket for a shaded-pole motor, comprising:

[0023] A universal bracket body 1, wherein a through hole 7 is provided in the middle of one side of the universal bracket body 1, mounting through holes 2 are provided on both sides of the universal bracket body 1, and a bearing mounting inner cavity 6 is provided in the center of the other side of the universal bracket body 1, wherein an oil-containing bearing 3 or a ball bearing 12 corresponding to the mounting through hole 2 is installed in the bearing mounting inner cavity 6;

[0024] In this embodiment, if Figure 1 , 5 -6, when an oil-containing bearing 3 is installed in the bearing installation inner cavity 6, a tapered bearing chamber 8 matching the oil-containing bearing 3 is provided in the bearing installation inner cavity 6, and a groove 14 is provided on the side wall of the tapered bearing chamber 8. A wool felt 4 is installed on the outer side of the tapered bearing chamber 8, and a pressing plate 5 for pressing the oil-containing bearing 3 is installed inside the bearing installation inner cavity 6. A positioning groove 9 is provided on the outer side of the tapered bearing chamber 8, and the wool felt 4 is embedded and installed in the positioning groove 9 to limit the wool felt 4. The wool felt 4 absorbs a lot of lubricating oil, and the lubricating oil can continuously enter the tapered bearing chamber 8. A limiting groove 10 engaged with the pressing plate 5 is provided in the middle part of the bearing installation inner cavity 6 to facilitate the positioning of the pressing plate 5. The positioning groove 9 and the limiting groove 10 can form an oil storage cavity, and a lot of lubricating oil can be injected into the oil storage cavity.
