Abstract

The utility model discloses a vibration generating device. The vibration generating device comprises a main shaft and a vibration exciter, wherein the vibration exciter is arranged on the main shaft and eccentric with the main shaft, the vibration exciter comprises two disks, each disk is provided with a through hole and more than two small holes, the main shaft is sleeved with the through holes which are eccentric with the disks, center distances between the disks and the small holes are different, the two disks are detachably connected with each other through the small holes having the equal center distances with the corresponding disk, and the small holes having the different center distances with the two disks are connected so that eccentric amplitude and namely different amplitudes of vibration of the vibration exciter can be achieved. The vibration generating device is simple in structure and convenient to operate.

Description

Vibration generating arrangement

Technical field

The utility model relates to a kind of vibration generating arrangement, and particularly a kind of amplitude facilitates adjustable vibration generating arrangement.

Background technology

Vibratory sieve mainly utilizes vibration generating arrangement, mainly, on eccentric main axis or main shaft, eccentric block is set, the centrifugal force that main shaft rotation produces, excite screen box to produce the motion of certain amplitude, on-the-sieve material is subject to the momentum that screen box passes to and produces continuous sling movement on the compass screen surface tilting, in the process that material and compass screen surface meet, make the particle that is less than sieve aperture thoroughly sieve, thereby realize screening, but the amplitude of existing vibration generating arrangement is non-adjustable, for obtaining various amplitude, need to change the weight of eccentric block, each like this eccentric block that all needs to install different eccentric weight in the situation that needing various amplitude, inconvenient operation.

For the deficiencies in the prior art, need improve existing vibration generating arrangement, its amplitude is facilitated adjustable.

Summary of the invention

In view of this, the utility model provides a kind of vibration generating arrangement, and its amplitude facilitates adjustable.

The utility model solves the problems of the technologies described above by following technological means:

Vibration generating arrangement of the present utility model, comprise main shaft and be arranged on main shaft and with the vibrator of spindle eccentricity, described vibrator is two disks, disk be provided be placed on main shaft and with the through hole of disk decentraction and two above with disc centre apart from different aperture, between two disks by aperture detachable be connected equal with disc centre distance.

Further, described vibrator is two, lays respectively at main shaft two ends.

Further, vibrator relative spindle eccentricity angle in described main shaft two ends is identical.

Further, between described vibrator and main shaft, be provided with tensioning sleeve.

The beneficial effects of the utility model: vibration generating arrangement of the present utility model, comprise main shaft and be arranged on main shaft and with the vibrator of spindle eccentricity, described vibrator is two disks, disk be provided be placed on main shaft and with through hole and two above apertures different with disc centre distance of disk decentraction, between two disks by with disc centre apart from equal detachable connection of aperture, the aperture of the different centre-to-centre spacing of two disks is connected, and can to realize the different eccentric weight of vibrator be different amplitudes.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is further described.

Fig. 1 is perspective view of the present utility model;

Fig. 2 is the explosive view of Fig. 1.

The specific embodiment

Below with reference to accompanying drawing, the utility model is elaborated, as shown in Figure 1: vibration generating arrangement of the present utility model, comprise main shaft 1 and be arranged on main shaft and with the vibrator 2 of spindle eccentricity, described vibrator is two disk 2a, disk be provided be placed on main shaft and with through hole 2b and two above aperture 2cs different with disc centre distance of disk decentraction, between two disks, by the aperture equal with disc centre distance, with bolt 2d, be connected, vibrator together rotates with main shaft, produce eccentric force and get final product excited vibrational, when needs are adjusted vibration amplitude, two disks are connected and can be realized by different apertures.

As the further improvement of technique scheme, described vibrator 2 is two, lays respectively at main shaft 1 two ends, vibrates more even.

As the further improvement of technique scheme, the relative spindle eccentricity angle of described main shaft two ends vibrator 2 is identical, can effectively prevent that the phenomenons such as main shaft eccentric wear from producing, the service life of extension device.

Further improvement as technique scheme, between described vibrator 2 and main shaft, be provided with tensioning sleeve 3, during installation, tensioning sleeve is under responsive to axial force, interior ring dwindles, and outer shroud magnifies, and makes to produce enough frictional force between the interior ring of tensioning sleeve and main shaft, tensioning sleeve outer shroud and vibrator, vibrator and main shaft are together rotated, and easy for installation.

Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of invention technical scheme, it all should be encompassed in the middle of the claim scope of invention.
