Thus, the spaces on both sides of the rotating member 332 can be sufficiently utilized for alignment and fastening, and the convenience in mounting and dismounting the driving wheel 350 can be further improved.

In addition, as shown in fig. 7, in combination with the second screw 370, the driving wheel 350 and the rotating member 332 can be fixed by using the second screw 370, so that the number of the first screw 360 and the third screw 380 can be reduced, which is beneficial to reducing the cost and ensuring the connection strength of the rotating member 332.

Specifically, when the carrying wheel 340 needs to be disassembled, the first screw connector 360 and the second screw connector 370 can be disassembled, and the third screw connector is not disassembled, so that the driving wheel 350 can still be fixed on the supporting unit 320. When the driving wheel 350 needs to be disassembled, the third screw 380 and the second screw 370 can be disassembled, and the first screw is not disassembled, so that the carrier wheel 340 can still be fixed on the supporting unit 320.

Optionally, there are 36 second screw members 370, 4 first screw members 360, and 4 third screw members 380; correspondingly, the number of the second internal threaded holes 352, the second through holes 304 and the third through holes 342 is 36; the number of the first escape holes 351, the first through holes 303, and the first internal thread holes 341 is 4, and the number of the second escape holes 344, the fourth through holes 305, and the third internal thread holes 353 is 4. Thus, the driving wheel 350 and the bearing wheel 340 can be fixed by 40 screw elements respectively, and can be arranged at equal intervals in the circumferential direction of the rotating element 332, that is, one screw element is arranged at intervals of 9 degrees, and there are 36 screw elements.

Alternatively, as shown in fig. 8, in another embodiment, the first side 301 is provided with a fourth internal threaded hole which is in threaded fit with the first threaded member 360; and the second side 302 is provided with a fifth internally threaded hole which is in threaded engagement with the third threaded member 380. Thus, the bearing wheel 340 is directly fixed on the first side 301 of the rotating member 332 through the first screw 360 and the fourth internally threaded hole, and the transmission wheel 350 is directly fixed on the second side 302 of the rotating member 332 through the third screw 380 and the fifth internally threaded hole.

In some embodiments, first side 301 is provided to protrude out of guide 331, and/or second side 302 is provided to protrude out of guide 331. Thus, the thickness of the rotation member 332 can be increased to increase the coupling strength of the rotation member 332. Further, the combination of the fourth internal thread hole and the fifth internal thread hole is beneficial to increasing the length of the internal thread hole arranged on the rotating member 332, so as to improve the fixing firmness of the bearing wheel 340 and the driving wheel 350.

It should be noted that the specific implementation manner of each screw connector includes screw fasteners such as bolts and screws; correspondingly, the screw head can be a bolt head or a screw head, etc.

It should be noted that the "rotating part" may be one of the parts of the module "mounting unit", that is, assembled with the "other components of the rotating part" into one module (such as a bearing), and then assembled modularly; the rotor may be mounted separately from the "other members of the mounting unit", i.e., may be integrated with the "other members of the rotor" in the present apparatus.

Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include at least one of the feature. In the description of the present disclosure, "a plurality" means at least two, e.g., two, three, etc., unless explicitly specifically limited otherwise.

In the present disclosure, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integral; can be mechanically or electrically connected; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meaning of the above terms in the present disclosure can be understood by those of ordinary skill in the art as appropriate.

In the present disclosure, unless otherwise expressly stated or limited, the first feature "on" or "under" the second feature may be directly contacting the first and second features or indirectly contacting the first and second features through an intermediate. Also, a first feature "on," "over," and "above" a second feature may be directly or diagonally above the second feature, or may simply indicate that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature may be directly under or obliquely under the first feature, or may simply mean that the first feature is at a lesser elevation than the second feature.

It will be understood that when an element is referred to as being "secured to," "disposed on," "secured to," or "disposed on" another element, it can be directly on the other element or intervening elements may also be present.
