Abstract
Provided is an eccentric wheel device of a broadband vibration exciter. Springs, sliding blocks, slide groove and other members are symmetrically additionally arranged on an eccentric wheel at one end of an original vibration exciter. The broadband eccentric vibration exciter can provide quite abundant frequency components. The vibration exciter further increases plenty of frequency components on the basis of reserving main frequency excitation of a traditional vibration exciter. Accordingly, on one hand, the vibration exciter can have a preferable adaptability, and on the other hand, work efficiency of shock excitation can also be improved.
Description
Technical field
The utility model relates to the vibrator field, especially a kind of eccentric wheel apparatus of wideband vibrator.
Background technology
For the most of vibrating mechanisms in the engineering reality, the main inertia vibration generator that relies on of vibration drives, so the structure of vibrator and performance, directly the operating efficiency of vibrating mechanism is had the very large impact.All there are the single or rare defective of excited frequency in the vibration tamp equipment such as vibrating head, frog hammer and the vibratory rammer, vibratory tamper that are used at present building trade, and this defective is very large on its operating efficiency impact.In order to overcome above defective, there are a lot of experts and scholars to do a large amount of useful work at this, some vibrator adopts multiple frequently (2 kinds of frequency contents) or converter technique.If but use multiple frequently technology, frequency content is fixed, so that vibrator adaptability is relatively poor; If use frequency modulation or converter technique, the one, will greatly increase the cost of vibrator, the 2nd, there is the problem of how to go the operating frequency of adjusting vibration exciter for different operating modes, in addition as using converter power supply to carry out frequency modulation by the eccentric mechanism of electric rotating machine, then owing to the mechanical transition process time of rotating eccentricity wheel is oversize, so control rate is too slow, amplitude accident out of control occurs easily.
Summary of the invention
In order to change traditional single defective of eccentric vibrator excited frequency, the utility model has designed a kind of eccentric mechanism that can produce the wideband exciting, to reach the purpose that improves vibration tamp mechanism work effect and enlarge the target scope.
The technical scheme that its technical problem that solves the utility model adopts is that symmetry adds the members such as upper spring, slide block and chute on the eccentric wheel of original vibrator one end.
The coefficient of elasticity of the spring of the correspondence position in the said apparatus equates, and slide block can slide in chute.
The beneficial effects of the utility model are that the wideband that enriches very much frequency content eccentric activator can be provided, this vibrator is on the basis that has kept traditional vibrator dominant frequency excitation, increased again a lot of frequency contents, so both can make vibrator that preferably adaptability is arranged, also can improve in addition the operating efficiency of exciting.
