Abstract
A vibration device belongs to the field of vibration machinery technologies, and includes an eccentric vibrator, a vibration motor, and a servo linear motion system. The eccentric vibrator includes at least a first eccentric body, a second eccentric body, and a connecting shaft. At least one of the first eccentric body or the second eccentric body is connected to the connecting shaft by a spiral groove and a boss structure matching the spiral groove. The servo linear motion system is connected to the connecting shaft. The servo linear motion system pushes the connecting shaft to move linearly, and drives the second eccentric body to rotate in a circumferential direction, and the first eccentric body remains stationary, so that adjustment of relative positions of the first eccentric body and the second eccentric body in the circumferential direction is implemented, and the purpose of controlling the magnitude of an exciting force in real time in a working process of equipment is implemented.
