Abstract
This invention publics a three-stars and dual-frequency driver, it has a whole box-type structure, passively runs by the helical gear force lubricates by the thin oil. In the three axes, the middle moves primarily, both sides of the middle are lay axes. A lay shaft makes a reversing synchro turning with a equal speed ,the other turns in a reverse non-uniform velocity way, the eccentricity block installs symmetrically on both sides of the axis, out of the box. Under the same exciting force, bearing reduces 1/3 lord, which solves the problem of large-scale driver, the structure is more compact and reasonable; in the identical period of vibration, through adjusting the parameters, for example, transmission ratio, exciting force and so on, it has two vibrations: high frequency low breadth and low frequency high breadth, which is propitious to dispersing and transporting of the material; the vibration direction angle can be adjusted if need.
Description
Technical field
The present invention relates to a kind of vibrator, especially a kind of three stars vibration exciter in dual frequency.
Background technology
Along with China's rapid economy development and continuous advancement in technology, industries such as coal, metallurgy, chemical industry, building materials, water power press for high throughput, and high efficiency vibratory sieve sieves, dehydration, de-mediated operation.Vibrator as the vibratory sieve heart becomes one of bottleneck of the maximization of restriction vibratory sieve, high efficiency.At present, known box vibrator has following problem: (1) has only twin axle, the increase of exciting force has only eccentric mass and the rotating speed by number that increases vibrator or increasing vibrator to solve, the former can take bigger space, increase installation difficulty, the latter is subjected to the restriction of bearing load carrying capacity and limit speed, also can not increase arbitrarily; (2) has only a kind of frequency in the course of work.
Summary of the invention
The present invention is directed to the problems referred to above, a kind of three stars vibration exciter in dual frequency is provided, it can not only effectively solve vibrator maximization problem, and low frequency high-amplitude and high frequency two kinds of mode of vibrations by a narrow margin can be provided, and improves screening or dehydrating effect.
Technical scheme of the present invention is: a kind of three stars vibration exciter in dual frequency, it is the exciting device as vibratory sieve.It is made up of casing, eccentric block, gear wheel, pinion, main shaft, driven shaft, bearing, sealing device.It is characterized in that: casing is a monoblock type, three axles are installed on the casing respectively, driving shaft is driven by belt pulley or flexible coupling by motor, main shaft is in the centre, all the other diaxons are in both sides, can parallelly install, also can be installed on the same horizontal plane, the axle bearings, bearing external application seal cover is with labyrinth and two kinds of form combination sealings of sealing ring, reduced the leakage of oil possibility, two eccentric blocks are equipped with in the every axle outside (the casing outside), three axles are by three gear drives mounted thereto, and one of them gear size of gear on the driving wheel and driven pulley is consistent, makes the constant speed backward rotation, have different with another gear size, do the variable speed backward rotation, different on two axles of eccentric block and other on the driven shaft of pinion are housed, can obtain required low frequency high-amplitude and high frequency two kinds of mode of vibrations by a narrow margin by design to the selection of gear ratio and eccentric block.Relative angle between the described eccentric block also can be regulated according to the needs of vibrating direction angle after the installation site of axle is determined.
The invention has the beneficial effects as follows: (1) adopts three excitings, and the load that every pair of bearing is shared under identical exciting force has reduced 1/3, thereby can adopt than the ting model bearing, helps the needs of vibratory sieve maximization, high frequencyization; (2) vibrating direction angle can be made adjustment flexibly according to the demand of different screening operations; Adopt low frequency high-amplitude and two kinds of vibration parameters of high frequency low frequency in (3) sieves simultaneously, high frequency helps the loose of material and saturating sieve by a narrow margin, improves screening or dehydrating effect, and the low frequency high-amplitude helps the conveying of material and improves disposal ability.
