specific Embodiment approach 1
[0010]Specific implementation mode 1: In this embodiment, the longitudinal bending sandwich transducer type disc stator is composed of an upper end disc 1-1-1, a lower end disc 1-7-1 and a longitudinal bending sandwich transducer 1-9; The curved sandwich transducer 1-9 is fixed between the upper disk 1-1-1 and the lower disk 1-7-1, and the longitudinal curved sandwich transducer 1-9 is composed of the front cover 1-1-4, the rear Cover 1-7-4, two pairs of bending piezoelectric ceramic sheets 1-2, two pairs of longitudinal vibration piezoelectric ceramic sheets 1-3, flange 1-4, preload shaft 1-5, thin copper electrode 1- 6 and an insulating sleeve 1-8; the front end cover 1-1-4 and the rear end cover 1-7-4 are quadrangular prisms whose section is rectangular and tapered, and the small end face and the upper end of the front end cover 1-1-4 The lower end surface of the disk 1-1-1 is fixedly connected, the small end surface of the rear end cover 1-7-4 is fixedly connected with the...
specific Embodiment approach 2
[0013] Specific implementation mode two: combination figure 2 , image 3 Describe this embodiment, the difference between this embodiment and the specific embodiment is that the front end cover 1-1-4 and the upper end disc 1-1-1, the rear end cover 1-7-4 and the lower end disc 1-7 -1 adopts a whole piece of metal material to be processed into an end cap-disc integrated piece. Other compositions and connection methods are the same as those in Embodiment 1. This processing method can achieve the purpose of reducing energy loss, and is conducive to improving the controllability of the particle vibration track on the surface of the driving tooth.
specific Embodiment approach 3
[0014] Specific implementation mode three: combination image 3 Describe this embodiment, the difference between this embodiment and the specific embodiment is that the upper end surface of the upper end disk 1-1-1 and the lower end surface of the lower end disk 1-7-1 are respectively processed with continuous comb-shaped driving teeth, On the continuous comb-shaped driving teeth on the upper end surface of the upper end disc 1-1-1, an upper end tapered surface 1-1-5 is processed, and an upper end thin-walled ring 1-1-1 is respectively processed on the outer side of the upper end disc 1-1-1. 2 and the upper end face flange 1-1-3, the inner side of the upper end disc 1-1-1 is respectively processed with the inner thin-walled ring 1-1-6 of the upper end face and the upper end face bearing seat 1-1-7; - The continuous comb-like drive teeth on the lower end face of -7-1 are processed with a lower end tapered surface 1-7-5, and the lower end face thin-walled ring 1-7-2 and the lowe...
