Problems solved by technology

[0002] The motor rotor in the related art includes a turntable and a rotating shaft directly fastened with the turntable. In order to ensure the weight reduction of the rotor, the turntable is mostly made of plastic material, but the turntable is prone to heat during rotation. The sol is prone to loosening, causing the motor to fail to work

Embodiment 1

[0068] A rotor assembly 1 such as Figure 1 to Figure 3 As shown, it includes: a rotating disk 10, a rotating shaft 20 and a fastener 30; the rotating shaft 20 is connected to the rotating disk 10; Specifically, the fastener 30 includes a fastening sleeve 32, which is used to be sleeved on the outer periphery of the rotating shaft 20. The circumferential direction of the fastening sleeve 32 has an opening 322, and the opening 322 runs through the fastening along the extension direction of the fastening sleeve 32. sleeve 32, so that the fastening sleeve 32 can clamp the rotating shaft 20.

[0069] In this embodiment, the fastener 30 is sheathed on the outer periphery of the rotating shaft 20 and clamps the rotating shaft 20 , and the fastener 30 is relatively fixed to the turntable 10 at the same time. Compared with the related art where the rotating shaft is only inserted on the turntable through interference fit, the setting of the fastener 30 further improves the stability ...

Embodiment 2

[0074] A rotor assembly 1, comprising: a rotating disk 10, a rotating shaft 20 and a fastener 30; the rotating shaft 20 is connected to the rotating disk 10; the fastener 30 is used to sleeve the outer circumference of the rotating shaft 20 and clamp the rotating shaft 20, and the fastener 30 includes The tightening sleeve 32 is sleeved on the outer periphery of the rotating shaft 20 , and the tightening sleeve 32 is in interference fit with the rotating shaft 20 so as to realize the relatively fixed position of the fastener 30 and the rotating shaft 20 .

Embodiment 3

[0076] In any of the above embodiments, if Figure 1 to Figure 4 As shown, the tightening sleeve 32 extends between the turntable 10 and the rotating shaft 20 , so that the rotating shaft 20 is connected to the turntable 10 through the tightening sleeve 32 .

[0077] In this embodiment, the fastening sleeve 32 on the fastener 30 extends between the rotating disk 10 and the rotating shaft 20, and the rotating disk 10 and the rotating shaft 20 in the rotor assembly 1 are connected by the fastener 30, replacing the rotating disk in the related art. 10 is in direct contact with the rotating shaft 20 , thereby reducing the interference and heat transfer between the rotating shaft 20 and the turntable 10 .

[0078] Optionally, the turntable 10 is a plastic turntable, and the fastener 30 is made of heat insulating material, which can reduce the heat transferred from the rotating shaft 20 to the turntable 10 and prevent the turntable 10 from being damaged due to excessive temperature....
