Description

[Technical Field]

[0002] This utility model relates to the field of shaded-pole motor technology, and in particular to a highly integrated shaded-pole motor support assembly. Background Technology

[0004] In existing shaded-pole motor bracket assemblies, the motor bracket, bearing, and nut are all independently installed. Therefore, during the assembly of the shaded-pole motor bracket, nuts need to be installed on the positioning posts at both ends of the bracket, and a bearing needs to be installed in the middle of the bracket. Then, the bracket is fixed by connecting the screw and the nut with a threaded connection. However, this structure has problems such as low production efficiency, concentricity difference, gaps between the outer circle of the bearing and the bearing of the bracket that easily generate noise, high labor intensity for employees, and low degree of automation. [Utility Model Content]

[0006] This invention overcomes the shortcomings of the prior art and provides a highly integrated shaded-pole motor support assembly.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] The highly integrated shaded-pole motor bracket assembly described above is characterized in that: the lower end of the positioning post extends out of the motor bracket.

[0010] The highly integrated shaded-pole motor bracket assembly described above is characterized in that: a nut is disposed on the upper side of the positioning post.

[0018] The beneficial effects of this utility model are:

[0019] In this utility model, the motor bracket, bearing, positioning column, and nut are integrally molded into a single structure. Integrating these three components onto the injection-molded motor bracket eliminates the need for manual insertion of the nut and bearing during assembly, significantly improving production efficiency. The injection mold boasts high precision, ensuring concentricity. The bearings fit without gaps, eliminating bearing clearance noise. The high degree of automation meets the requirements of automated equipment production. The simple structural design and combined production of the three components reduce warehouse management costs.

[0025] The technical solutions in the embodiments of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.

[0026] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indication will also change accordingly. Furthermore, descriptions involving "preferred," "second-best," etc., in this utility model are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined as "preferred" or "second-best" may explicitly or implicitly include at least one of those features.

[0027] like Figure 1-3 As shown, a highly integrated shaded-pole motor support assembly includes a motor support 1. A bearing 2 is axially positioned vertically at the center of the motor support 1. Positioning pins 3 and nuts 4, also axially positioned vertically and connected to screws, are located at both ends of the motor support 1. The positioning pins 3 have through holes 5 along their length for the screw to pass through. The motor support 1 is an injection-molded part, and the motor support 1, bearing 2, positioning pins 3, and nuts 4 are an integral structure formed by in-mold injection molding. During assembly, the shaded-pole motor shaft passes through the bearing 2 and is then threadedly connected to the nuts 4 via the positioning pin through the through holes 5 of the positioning pins 3. In this case, the bearing, positioning column, and nut are embedded in the injection molded motor bracket 1, eliminating the need for manual installation of nuts and bearings during assembly, which greatly improves production efficiency; the injection mold has high precision and ensures concentricity; the bearing fits without gaps, eliminating bearing fit noise; the degree of automation is high, which can meet the production needs of automated equipment; the structural design is simple; the combined production of the three components, bearing 2, positioning column 3, and nut 4, reduces warehouse management costs.

[0028] like Figure 1-3 As shown, the lower end of the positioning post 3 extends out of the motor bracket 1, which facilitates the screw to pass through the positioning post through hole 5 of the positioning post 3 and to achieve positioning and installation through the positioning post 3.

[0029] like Figure 1-3 As shown, nut 4 is set on the upper side of positioning post 3, so that the screw is positioned through the positioning post through hole 5 of positioning post 3 and then connected and fixed to nut 4; the upper side of motor bracket 1 is provided with bracket through hole 11 on the upper side of nut 4, so that the screw connection end can extend out to adjust the locking tightness.

[0030] like Figure 1-3 As shown, the positioning pin through hole 5 and the nut 4 threaded hole are concentrically set, which allows the screw to pass through the positioning pin through hole 5 and be accurately threadedly connected and fixed to the nut 4.

[0031] like Figure 1-3As shown, the motor bracket 1 includes a bearing bracket portion 13 and positioning connection portions 12 respectively disposed on both sides of the bearing bracket portion 13. The bearing 2 is disposed on the bearing bracket portion 13, and the positioning pin 3, nut 4 and bracket through hole 11 are disposed on the positioning connection portion 12. The positioning pin 3 and nut 4 are disposed on the outer side of the positioning connection portion 12 to make the motor bracket 1 bear force evenly. A reinforcing rib 14 is provided on the inner side of the bottom surface of the positioning connection portion 12 to improve the connection strength between the bearing bracket portion 13 and the positioning connection portion 12.

[0032] In this case, bearing 2 is a 625, 626, or 608 bearing; nut 4 is an M3, M4, or M5 nut, and different specifications of bearings and nuts can be set according to actual usage requirements.

[0033] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
