Embodiment 1

[0034] see Figure 1 ~ Figure 3 , is a compact vibrator, including a first eccentric rotor 1, a second eccentric rotor 2, a third eccentric rotor 3, and a fourth eccentric rotor 4, wherein the first eccentric rotor 1 and the third eccentric rotor 3 have the same structure, The second eccentric rotor 2 has the same structure as the fourth eccentric rotor 4 . The first eccentric rotor 1 and the second eccentric rotor 2 , the third eccentric rotor 3 and the fourth eccentric rotor 4 each constitute an eccentric rotor group.

[0035] In this embodiment, the first eccentric rotor 1 includes a first rotating shaft 101 and an eccentric block, and the eccentric block includes a first concave portion 103 and a first convex portion 102; the first concave portions 103 and the first convex portions 102 are alternately arranged on the first rotating shaft 101 Above: the first concave portion 103 and the first convex portion 102 are rectangular. The second eccentric rotor 2 includes a seco...

Embodiment 2

[0038] see Figure 4 The difference between this embodiment and Embodiment 1 is that the shapes of the first concave portion 103 , the first convex portion 102 , the second concave portion 203 , and the second convex portion 202 are trapezoidal.

Embodiment 3

[0040] see Figure 5 The difference between this embodiment and Embodiment 1 is that the shapes of the first concave portion 103 , the first convex portion 102 , the second concave portion 203 , and the second convex portion 202 are triangular.

Abstract

The invention belongs to the technical field of vibration equipment, and relates to a vibration exciter eccentric rotor set which comprises a first eccentric rotor and a second eccentric rotor. The installation center distance of the first eccentric rotor and the second eccentric rotor is smaller than the sum of the rotation radiuses of the first eccentric rotor and the second eccentric rotor, and the first eccentric rotor and the second eccentric rotor do not interfere with each other when rotating around respective rotation centers. The compact vibration exciter comprises at least one eccentric rotor set, the rotating speed ratio of the first eccentric rotor to the second eccentric rotor is 1: 2, and the rotating directions of the first eccentric rotor and the second eccentric rotor are opposite. Compared with a traditional vibration exciter, under a same exciting force condition, the center distance of the eccentric rotor can be properly reduced, the vibration exciter is compact in structure, especially suitable for occasions with limited space sizes, light in equipment weight and relatively low in cost.

Description

technical field [0001] The invention belongs to the technical field of vibration equipment, and relates to a compact vibration exciter and an eccentric rotor group thereof. Background technique [0002] The exciter is a device attached to some machinery and equipment to generate excitation force, and is an important part of using mechanical vibration. The vibrator can make the excited object obtain a certain form and size of vibration, so as to perform vibration and strength tests on the object, or to calibrate vibration testing instruments and sensors. The vibrator can also be used as an exciting part to form a vibrating machine to realize the conveying, screening, compacting, forming and tamping of soil and gravel for materials or objects. According to the different excitation types, the vibrator is divided into inertial electric type, electromagnetic type, electro-hydraulic type, pneumatic type and hydraulic type. The exciter can generate unidirectional or multidirectio...
