Description

Technical Field

[0001] This utility model relates to the field of motors, and in particular to a novel rotor riveting structure. Background Technology

[0002] The existing rotor and shaft are synchronously transmitted by riveting. However, riveting is an irreversible rigid connection. Once the relative position of the rotor and shaft (such as axial and radial fit) is riveted, it is fixed. If poor dynamic balance is found during assembly (uneven rotor mass distribution leads to rotational vibration), the rotor position needs to be adjusted (such as adding balance blocks or fine-tuning the fit clearance). It is difficult to correct after riveting and can only be disassembled and re-riveted, which greatly increases the assembly difficulty and maintenance cost. Therefore, a new rotor riveting structure is proposed. Utility Model Content

[0003] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0004] A novel rotor riveting structure includes a stator support with a rotating shaft vertically riveted to its bottom. A rotor is vertically inserted inside the stator support and rotates within it. The bottom of the rotor contacts the top of the rotating shaft, and the rotor rotates simultaneously with the top of the rotating shaft while rotating inside the stator support. The rotating shaft provides rotational support for the rotor, and the shaft and rotor rotate asynchronously. A housing covers the top of the stator support, and a base is vertically positioned in the middle of the housing and inserted into the stator support. The rotor passes through the base and rotates at the middle position of the base, allowing the rotating rotor to serve as a direct output end.

[0005] Preferably, the stator support is provided with a stator core, and the stator core is distributed around the inside of the stator support. A PCBA is provided between the stator support and the stator core, and the PCBA is disposed on the stator support and electrically connected to the stator core.

[0006] Preferably, a first ball bearing is provided between the base and the rotor, and the first ball bearing is horizontally mounted at the top end inside the base, and the rotor rotates through the first ball bearing and at the middle position of the first ball bearing.

[0007] Preferably, a second ball bearing is provided between the base and the rotor, and the second ball bearing is horizontally mounted at the bottom of the base. The rotor passes through the second ball bearing, and the second ball bearing is parallel to the first ball bearing. The rotor rotates at the middle position of the second ball bearing.

[0008] Preferably, a retaining ring is provided between the rotor and the base, and the retaining ring is inserted laterally into the outside of the rotor and rests horizontally on the base.

[0009] Compared with the prior art, the beneficial effects of this utility model are: the rotor is riveted to a separate base, and the shaft is not riveted to the rotor, but directly riveted to the stator support. The shaft only plays a fixing role and is directly output by the rotor, so as to improve reliability and reduce maintenance during subsequent rotor maintenance.

[0010] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-6 In this embodiment of the present invention, a novel rotor riveting structure includes a stator support 1, wherein the stator support 1 is provided with a rotating shaft 3, and the rotating shaft 3 is vertically riveted to the bottom end of the stator support 1. A rotor 3 is vertically inserted inside the stator support 1, and the rotor 3 rotates inside the stator support 1. The bottom end of the rotor 3 contacts the top end of the rotating shaft 3, and the rotor rotates simultaneously at the top end of the rotating shaft 3 while rotating inside the stator support 1. Thus, the rotor 3 can be rotated and supported by the rotating shaft 2, and the rotating shaft 2 and the rotor 3 rotate asynchronously. A shell 5 is provided on the top of the stator support 1, and a base 4 is vertically provided in the middle of the shell 5. The base 4 is inserted into the stator support 1, and the rotor 3 passes through the base 4. The rotor 3 rotates at the middle position of the base 4, so that the rotating rotor 3 can be used as a direct output end.

[0021] The stator support 1 is provided with a stator core 7, and the stator core 7 is distributed around the inside of the stator support 1. A PCBA (not shown in the figure) is provided between the stator support 1 and the stator core 7, and the PCBA is provided on the stator support 1. The PCBA is electrically connected to the stator core 7, thereby changing the magnetic field between the stator core 7 and the rotor 3, which in turn drives the rotor 3 to rotate.

[0022] A first ball bearing 8 is provided between the base 4 and the rotor 3. The first ball bearing 8 is horizontally mounted at the top of the base 4, and the rotor 3 rotates through the first ball bearing 8 and at the middle position of the first ball bearing 8.

[0023] A second ball bearing 9 is also provided between the base 4 and the rotor 3, and the second ball bearing 9 is horizontally mounted at the bottom of the base 4. The rotor 3 passes through the second ball bearing 9, and the second ball bearing 9 and the first roller bearing 8 are parallel to each other. The rotor 3 rotates at the middle position of the second ball bearing 9. Thus, the first ball bearing 8 and the second roller bearing 9 can keep the rotor 3 stable when it rotates inside the base 4.

[0024] A retaining ring 6 is also provided between the rotor 3 and the base 4. The retaining ring 6 is inserted laterally into the outside of the rotor 3 and is mounted horizontally on the base 4. Thus, the retaining ring 3 can prevent the rotor 3 from detaching when it rotates inside the base 4.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
