Abstract
The invention relates to an inertia vibrator which can control the mechanical noise. It is formed by a base and a body supported on the base. Wherein, the body has a exciter, inside which there is a gap between the outer ring of eccentric bearing and a ring of flexible element; the exciting force generated by eccentric bearing is not directly transmitted to the body. The best choice is that the inner hole of bearing base is in taper shape, and the taper flexible element via the end cover is compressed into the gap between the outer ring of bearing and the bearing base. Said flexible element is made from flexible metal, metallic rubber or nylon rubber material. The invention can reduce the noise of machine body and the noise of bearing, while the reduced noise can reach 5-10dB (A).
Description
Technical field: the present invention relates to the noise control of inertial oscillation machinery and effective technological method that reduces, and formed low noise inertial oscillation machinery, as vibrating sieve, oscillating feeder etc., particularly make method that turning member error such as vibration exciter bearing causes that strong noise reduces and formation than low noise inertial oscillation machinery.
Background technique: the application of inertial oscillation machinery is very extensive, as vibrating sieve, oscillating feeder etc.A large amount of both at home and abroad at present high problems of using of inertial oscillation machinery ubiquity noise, unresolved always for many years.A lot of about vibrating machine noise problem researcher, its method can be divided into two classes, and a kind of is to start with from structural material, promptly adopts low noise material and parts (Zhu Hua, the development of low noise dual-axis vibration sieve, mechanical engineering journal, 1998,4).This construction expenditure is higher, is difficult for popularizing.Another kind is to start with from excitation principle, with spring body is separated with vibration exciter, the change direct-drive into indirect excitation (1, Yuan Huiqun, novel elastic coupling excitation vibrating sieve optimum Design of Parameters, Machine Design and manufacturing, 2,000 06; 2, CSTAD, Jiaotong University Of East China, shock and vibration absorption type vibrating sieve).Because this method is contained in the vibration exciter outside with spring, is unfavorable for the especially reduction of bearing self-noise of vibration exciter, therefore total noise reduction is limited.The major defect of existing inertial oscillation machinery is, adopt direct exciting mode, the eccentric shaft vibration exciter is directly installed on the body, not only there is the excitation force of frequency of okperation to pass to body during work, and the High-frequency Interference power that causes owing to the error of turning members such as bearing is also passed to body simultaneously, thereby cause the high frequency elastic vibration of body, and then produce strong noise.
Summary of the invention:
The present invention solves the problem that inertial oscillation machinery is reduced inertial oscillation machinery noise, and a kind of inertial oscillation machinery noise control method and low noise inertial oscillation machinery that reduces noise is provided.
The present invention adopts indirect exciting mode, and its principle is that the excitation force that eccentric shaft produces is not directly passed to body, but acts on body by an elastic element.Can realize guaranteeing the body working amplitude like this, reduce the body dither and then reduce the purpose of noise, the experimental study result shows that the mounting point of elastic element is bigger to the noise reduction influence, is installed in the vibration exciter internal effects and is better than the outside.Therefore with existing indirect exciting mode different be, used elastic element is installed between vibration exciter internal bearings outer ring and the bearing support, has the double action that reduces engine body noise and the noise of bearing own this moment concurrently, total noise reduction can reach 5～10dB (A).So inertial oscillation of the present invention machinery noise control method is reserved certain interval and is added with a circle elastic element between the vibration exciter inner eccentric shaft bearing outer-ring of inertial oscillation machinery and bearing support exactly, the excitation force that eccentric shaft produces is not directly passed to body.Preferably inner hole of bearing seat is taper, during installation the taper elastic element is pressed into gap between bearing outer ring and the bearing support by end cap.One circle elastic element adopts metal, metal-rubber or nylon rubber material to make.Low noise inertial oscillation machinery of the present invention, is supported on the body of support at organic block, and body has vibration exciter, reserves certain interval between the vibration exciter inner eccentric shaft bearing outer-ring of inertial oscillation machinery and the bearing support and is added with a circle elastic element.Inner hole of bearing seat is taper, during installation the taper elastic element is pressed into gap between bearing outer ring and the bearing support by end cap.One circle elastic element adopts metal, metal-rubber or nylon rubber material to make.Used in addition elastic element can adopt metal, metal-rubber or nylon rubber material, and that this material has is high temperature resistant, oil resistant, long characteristics of life-span.
The present invention compared with the prior art, it is as follows to have advantage:
1), embed elastic element between vibration exciter internal bearings outer ring and bearing support, this element has the double action that reduces engine body noise and the noise of bearing own concurrently, and noise reduction is remarkable, can reach 5～10dB (A).
2), used elastic element adopts metal, metal-rubber or nylon rubber material, and high temperature resistant, oil resistant, long characteristics of life-span are arranged.
3), cost is low, easy to implement.Do not need other investment for existing vibrating machine manufacturer.
Description of drawings: accompanying drawing has been represented a kind of low noise inertial oscillation machinery system schematic of the present invention, further specifies below in conjunction with the example of accompanying drawing.
Specific embodiment: the mechanical system of this low noise inertial oscillation of the present invention, organic block 6, be supported on the body 1 on the support vibration-isolating spring 5, body has vibration exciter 2, reserves certain interval between the bearing outer ring of the vibration exciter inner eccentric shaft 3 of inertial oscillation machinery and the bearing support and is added with a circle elastic element 7.Reserve certain interval between bearing 4 outer rings and bearing support, inner hole of bearing seat is taper, during installation the taper elastic element is pressed in the gap between bearing outer ring and the bearing support by end cap, regulates pretightening force with screw.Other position of all of machine is installation and processing routinely all.This inertial oscillation machinery noise control method, also can be used in the transformation of existing equipment, only need vibration exciter inner eccentric shaft bearing endoporus is processed into taper, ring cone-shaped metal rubber elastic element is inserted the ring tapered gaps that forms between bearing and the bearing support, push down by end cap, end cap gets final product by screw.So just can control by inertial oscillation machinery noise, reach the purpose that reduces noise.
