Abstract
The utility model relates to a chaotic vibration exciter. The chaotic vibration exciter can be widely used in the machine field, the building project field, the chemical engineering field, the agricultural engineering field, etc. Being different from the existing vibration electric machine, the chaotic vibration exciter is characterized in that the chaotic vibration principle is used. An eccentric sleeve (5) is sheathed with an eccentric rotating disk (7) which can rotate on the eccentric sleeve (5). The eccentric sleeve (5) and the eccentric rotating disk (7) can be respectively made into two. The relative angle of the eccentric sleeve (5) can be adjustable. Through the adjustment of the speed of the electric machine, small-range periodic vibration or large-range chaotic vibration (accompanied with impacting anomalous vibration) can be obtained. The utility model has the advantages of small size, high vibrating efficiency and variable frequency. The utility model can be suitable for different vibrating operations.
Description
The utility model discloses a kind of Chaotic Vibration Exciter, can be widely used in fields such as machinery, civil engineering, chemical industry, agriculture project, belong to the vibrating motor class.
Existing shock electric machine mostly is the constant speed three phase electric machine, and this body is long-pending big, and the actual measurement vibration efficiency is low, fixedly eccentric disc is housed in the rotating shaft, and not only vibration frequency is non-adjustable, and oscillatory type is single, soft simple harmonic oscillation can only be obtained, the demand of different vibration services can not be adapted to.
The purpose of this utility model is to provide a kind of volume little, and vibration frequency is adjustable, and actual measurement vibration efficiency height has two kinds of vibrations of chaos and simple harmonic quantity condition concurrently, can adapt to the novel vibrator of different vibration service needs.
The purpose of this utility model is achieved in that and is set with eccentric rotating disk (7) on the eccentric bushing (5), and this off-centre rotating disk can be gone up at eccentric bushing (5) and rotate, and eccentric bushing (5) and eccentric rotating disk (7) can respectively be made two, and the relative angle of eccentric bushing (5) is adjustable.
Advantage of the present utility model is:
1. have two kinds of vibrations of chaos and simple harmonic quantity condition concurrently, actual measurement vibration efficiency height: the utility model adopts rotating shaft to tighten eccentric bushing, and eccentric rotating disk of empty again cover is formed the chaotic vibration system on it.Through testing: when frequency is to be below the 28HZ periodic vibration; When frequency is chaotic vibration significantly at 34HZ; When frequency at the 28-33HZ chaotic vibration (fall in the periodic vibration and add chaotic vibration) that is as the criterion, and along with frequency increases, the composition of chaotic vibration increases.In vibration service, chaotic vibration has higher actual measurement vibration frequency than simple harmonic oscillation.
2. can pass through speed regulator (11) frequency modulation, can adapt to different vibration service needs: because this machine is driven by variable speed electric motors, particularly, by transferring motor speed can get small size periodic vibration or chaotic vibration (with the irregular oscillation of impacting) significantly, can adapt to different vibration service needs.
3. volume is little.
Below in conjunction with accompanying drawing the utility model is further specified:
Accompanying drawing 1 is a schematic diagram of the present utility model.
By accompanying drawing 1 as can be known, the utility model comprises bearing block (1), supporting shaft (2), single-phase variable speed electric motors, particularly (3), belt (4), eccentric bushing (5), nut (6), eccentric rotating disk (7), outer cover (8), shell (9), support (10), speed regulator (11).
Connected mode of the present utility model is such: about two bearing blocks (1) supporting shafts (2), rotating shaft is passed through speed regulator (11) by former and later two single-phase variable speed electric motors, particularlies (3), by about two belts (4) drive, about two eccentric bushings (5) be pressed on the left and right sides belt pulley of rotating shaft (2) with nut (6) by lock washer, about two eccentric rotating disks (7) can about rotate on two eccentric bushings, shell is fixed on the support (10), about two outer covers (8) be fixed on the shell (9).
Claims (2)
1. a Chaotic Vibration Exciter comprises bearing block (1), rotating shaft (2), belt (4), eccentric bushing (5), nut (6), outer cover (8), shell (9), support (10) is characterized in that being set with on the eccentric bushing (5) eccentric rotating disk (7), and this off-centre rotating disk can be gone up at eccentric bushing (5) and rotate.
2. Chaotic Vibration Exciter as claimed in claim 1 is characterized in that eccentric bushing (5) and eccentric rotating disk (7) can respectively make two.
