Abstract
The utility model relates to a kind of twin axle self-synchronization exciting device, comprising: exciter support; Also comprise: two root systems being horizontally through exciter support; Every root system comprises: the coupling spindle be connected with motor and be successively connected the first adjustable eccentric block, first piece of eccentric activator, the second adjustable eccentric block, the 3rd adjustable eccentric block, second piece of eccentric activator and the 4th adjustable eccentric block; Second adjustable eccentric block is connected by jackshaft with the 3rd adjustable eccentric block; First piece of eccentric activator and second piece of eccentric activator are separately fixed on the left and right side frame of exciter support; Eliminate synchromesh gear or Timing Belt, equipment runs only needs a small amount of maintenance, and operation troubles rate is lower; Owing to adopting motor synchronizing technology, do not have gear or Timing Belt, vibrator two root system can adjust wheelbase according to designing requirement, realizes the translation of sieve or becomes amplitude vibration track; The adjustment at exciting angle can be realized by moving integrally vibrator.
Description
Technical field
The utility model relates to a kind of for various straight line, elliptically vibrating screen and for the classification of the industries such as mine, metallurgy, coal, the vibratory sieve of de-mediated and dehydration etc., particularly relates to a kind of twin axle vibrator.
Background technology
Vibratory sieve, for realizing translation straight line or elliptical vibration track, generally will adopt twin shaft or multiaxis vibrator.Non-one-eccentric rotor type vibrator has vibrator synchronous operation problem.It is synchronous that relatively conventional double-shaft vibration exciter generally adopts gear or Timing Belt to realize, and the above-mentioned method of synchronization has mechanical complicated structure, during operation, vibrator temperature rise ratio is higher, maintenance trouble is frequent, have fault rate higher etc. shortcoming.
Summary of the invention
The utility model technical issues that need to address there is provided a kind of twin axle self-synchronization exciting device, by adopting motor synchronizing technology, eliminating synchromesh gear or Timing Belt, frame for movement is simplified greatly, equipment runs only needs a small amount of maintenance, and operation troubles rate is lower.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: exciter support; Also comprise: two root systems being horizontally through exciter support; Described every root system comprises: the coupling spindle be connected with motor and be successively connected the first adjustable eccentric block, first piece of eccentric activator, the second adjustable eccentric block, the 3rd adjustable eccentric block, second piece of eccentric activator and the 4th adjustable eccentric block; The second described adjustable eccentric block is connected by jackshaft with the 3rd adjustable eccentric block; First piece of described eccentric activator and second piece of eccentric activator are separately fixed on the left and right side frame of exciter support.
Compared with prior art, the beneficial effects of the utility model are: adopt motor synchronizing technology, eliminate synchromesh gear or Timing Belt, frame for movement is simplified greatly, and equipment runs only needs a small amount of maintenance, and operation troubles rate is lower; Owing to adopting motor synchronizing technology, do not have gear or Timing Belt, vibrator two root system can adjust wheelbase according to designing requirement, realizes the translation of sieve or becomes amplitude vibration track; The adjustment at exciting angle can be realized by moving integrally vibrator.

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail:
From Fig. 1, Fig. 2, Fig. 3: the utility model comprises: exciter support 1; Also comprise: two root systems being horizontally through exciter support 1; Described every root system comprises: the coupling spindle 3 be connected with motor and the first adjustable eccentric block 5, first piece of eccentric activator 2, the second adjustable eccentric block 51, the 3rd adjustable eccentric block 52, second piece of eccentric activator 21 and the 4th adjustable eccentric block 53 that are connected successively; The second described adjustable eccentric block 51 is connected by jackshaft 4 with the 3rd adjustable eccentric block 52; Described first piece of eccentric activator 2 and second piece of eccentric activator 21 are separately fixed on the left and right side frame of exciter support 1.
During work, two described root systems reversely rotate under motor drives, and motor synchronizing runs.
In described every root system, four groups of adjustable eccentric block mass eccentricity squares are identical, and the mass eccentricity square of the eccentric block of disalignment system can be different.
The utility model is by the ratio of the eccentric block quality eccentricity of adjustment two root system, and the elliptical orbit of the long and short footpath ratio that shaker vibration path implementation can be made different, can realize straight-line trajectory when the eccentric block quality eccentricity of two axles is identical.Block eccentric activator generally adopts grease lubrication, also can adopt oil or oil, fat mixed lubrication according to use occasion.
As shown in Figure 4, the utility model is used for the situation of bananas type elliptically vibrating screen.Utility model twin axle self-synchronization exciting device, is arranged on the top of vibratory sieve 6 in this example.Exciter support 1 is connected with vibratory sieve casing 7 bolt 8.Vibrator moves integrally on screen box by bolt hole displacement mounting means, and when vibrator moves to pan feeding direction, exciting angle is strengthened, and when vibrator is shifted to discharge end, exciting angle is reduced.
Vibrator can integral demounting, can keep in repair easily and change.
