- the present rotating shaft 8 is different from the conventional rotor shaft except that the outer diameter of the rotating shaft is made large, and an eccentric shaft is formed.
- the eccentric structure of the rotating shaft of this embodiment is formed by milling an elongated groove 81 in the axial direction at the intermediate portion of the shaft (as shown in Fig. 2).
- the length and depth of the milling can be determined according to specific needs, or the partial milling vibration body is mainly composed of the eccentric body 3 and the eccentric body sleeve 4, the eccentric body 3 is sleeved on the rotating shaft 8, and the two ends are supported by the first rolling bearing 2 supporting the rotating shaft 8.
- the third rolling bearing 6 is limited.
- the eccentric body 3 is an eccentric body 3 having a cylindrical shape, a half piece in the inner body, and an eccentric body sleeve 4 in the eccentric body.
- the vibrating rod is connected to the external DC inverter controller controlled by the integrated single-chip microcomputer through the hose, and the DC variable frequency constant speed control is performed on the motor.
