Iso9001 Mechanical Vibration Exciter For Vibrating Screen Machine

Product Specification

Vibration exciter is a device attached to certain machinery and equipment to generate excitation force, and it is an important component for utilizing mechanical vibration. The exciter can make the excited object obtain a certain form and size of vibration, so as to conduct vibration and strength tests on the object, or calibrate the vibration testing instruments and sensors.

The exciter can also be used as an excitation component to form a vibrating machine, which is used to realize the conveying, screening, compacting, forming and tamping of soil sand and gravel of materials or objects. According to the different excitation types, vibration exciters are divided into inertia electric type, electromagnetic type, electro-hydraulic type, pneumatic type and hydraulic type. The exciter can generate unidirectional or multidirectional, harmonic or non-harmonic excitation force.

Vibrating screen is a necessary screening equipment in the sand making industry, which is mainly used to separate sand particles of different particle sizes. The principle of vibrating screen is relatively simple. The main device is the exciter. This article mainly introduces the exciter of the vibrating screen. The inertial exciter is an important part of the vibrating screen, and it has two types: the single-axis exciter and the double-axis exciter.

(1) Uniaxial vibration exciter

According to the configuration of the eccentric mass, the uniaxial exciter is divided into four types: the partial mass wheel type, the partial mass shaft type, the partial mass wheel shaft type and the partial mass block type. compound form. The advantages of the partial mass wheel type are that it is easy to manufacture, the bending moment in the middle of the shaft is small, the M is adjustable, and the excitation force is adjustable. The main advantage of the eccentric shaft type is that the structure is simple, and the disadvantage is that it is difficult to manufacture, the bending moment in the middle of the shaft is large, and the exciting force is not adjustable. The main advantage of the eccentric axle type is that the bending moment in the middle of the axle is the smallest, and the excitation force is adjustable. The advantage of the eccentric block type is that it has no long shaft and is easy to manufacture; there is no bending moment in the middle of the shaft; the invalid eccentric mass is the smallest, and the exciting force is adjustable; the bearing life is long, and the disadvantage is that the structure is more complicated.

(2) Biaxial vibration exciter

A biaxial exciter is basically a combination of two or two sets of uniaxial exciters. The uniaxial exciters classified according to the eccentric mass distribution method can be combined into corresponding biaxial exciters. According to the shape of the exciter, in essence, it is based on the length of the rotating shaft and the convenience of the overall installation and disassembly of the screen box.

(3) Vibration motor

Vibration motor is a general-purpose electromechanical product that combines a motor and an exciter into one, and is used in a variety of vibrating machines including vibrating screens. Compared with other vibration exciters, the biggest advantage of the vibration motor is that it has a simple structure and no longer needs any transmission devices such as tapes and couplings. Restriction, generally only applicable to small vibrating screen.

And also have flanged disc type exciter, pedestal exciter and triaxial exciter etc. We can design the exciter according to customer’s requests.
