Description
Vynález sa týká rotačného vibraěného zariadenia s plynulou reguláciou amplitudy, používaného najma v stavebnictve na vyvodzovanie vibrácii potřebných například na zhutňovanie a homogenizáciu betonu.BACKGROUND OF THE INVENTION The invention relates to a rotary vibratory device with continuous amplitude control, used in particular in the construction industry to derive the vibrations needed for example for compacting and homogenizing concrete.
Doteraz používané zariadenia pracujú na principe vyvodzovania vibrácii vplyvom odstredivej sily vyvodzovanej rotáciou excentricky uloženej hmoty, pričom velkost amplitudy je konštantná, daná konštrukčnými parametrami vibrátora. Nevýhodou týchto zariadení je, že v prie běhu pracovnej činnosti neumožňujú plynulú reguláciu velkosti amplitúdy tak, ako by si to vyžadovali technologické požiadavky.The devices used hitherto operate on the principle of inducing vibrations due to the centrifugal force exerted by the rotation of the eccentrically deposited mass, the magnitude of the amplitude being constant given by the design parameters of the vibrator. The disadvantage of these devices is that they do not allow continuous regulation of the amplitude during operation, as required by technological requirements.
Tieto nedostatky odstraňuje rotačně, vibračně zariadenie s plynulou reguláciou amplitúdy, pozostávajúce z pohonného motora s hriadelom pevne spojeným s rotačným telesom podlá vynálezu, ktorého podstatou je, že rotačně teleso pozostáva zo solenoidu a posuvného jadra, pričom vývody solenoidu sú zapojené na zberače, ku ktorým priliehajú kontakty připevněné pomocou 'ramien k rámu pohonného motora.These drawbacks are eliminated by a rotational, vibration, continuous amplitude control device comprising a drive motor with a shaft fixedly coupled to a rotary body according to the invention, which consists in that the rotary body consists of a solenoid and a sliding core, the solenoid outlets being connected to the contacts fastened by the arms to the frame of the drive motor abut.
Výhodou zariadenia podlá vynálezu je možnost*plynulej regulácie excentricity rotačného telesa vibrátora a v dSsledku toho aj plynulej regulácie amplitúdy vibrácii v rozsahu od nuly do maxima daného konštrukčným převedením rotačného vibraěného zariadenia.An advantage of the device according to the invention is the possibility to continuously control the eccentricity of the rotary vibrator body and consequently the continuous control of the vibration amplitude in the range from zero to the maximum given by the structural conversion of the rotary vibrating device.

Zariadenie podlá vynálezu pozostáva z pohonného motora £ s hriadelom g, ktorý je pevne spojený s rotačným telesom χ, pozostávajúcim zo solenoidu 2 a posuvného jadra 2' pričom vývody 4, 2 solenoidu 2 sů zapojené na zberače $, £, ku ktorým priliehajú kontakty 11, 12 připevněné pomocou ramien 13, 14 k rýmu pohonného motora £ a celá funkčná časťje chráněná krytom 15The device according to the invention consists of a drive motor 6 with a shaft g which is fixedly connected to a rotary body χ consisting of a solenoid 2 and a sliding core 2 ', the pins 4, 2 of the solenoid 2 being connected to the collectors $, 6 to which contacts 11 contact. , 12 attached by means of arms 13, 14 to the rim of the drive motor 6 and the entire functional part is protected by a cover 15.
Funkcia zariadenia podlá vynálezu je nasledovnáj pohonný motor £ vytvára potřebný krútiaci moment, ktorý je hriadelom § prenášaný na rotačné teleso χ, pozostávajúce zo solenoidu 2 a posuvného jadra 2· Na solenoid 2 sa privádza regulačně napatie cez ramená 13, a kontakty 11, 12, zberače £, £ a vývody 4, 5. pri rotácii rotačného telesa χ okolo svojej osi má posuvné jádro 2 snahu účinkom odstredivej sily zaujat'polohu s maximálnou možnou excentricitou umožněnou konštrukciou zariadenie. pri zaktivovaní solenoidu 2 regulačným napBtim sa znižuje excentricita rotujúceho posuvného jadra 2 podlá stupňa aktivácie, čim sa dosahuje plynule měnitelný kinetický moment a v dósledku tohot sa plynule meni i amplitúda vibrácii od nuly do maxima daného konštrukčným převedením rotačného vibračného zariadenia s plynulou reguláciou amplitúdy podlá vynálezu.The function of the device according to the invention is as follows: the drive motor 6 generates the necessary torque which is transmitted by the shaft 6 to the rotary body χ, consisting of a solenoid 2 and a sliding core 2. The solenoid 2 receives control voltage via the arms 13 and contacts 11, 12; £ collectors, £ and terminals 4, 5 the rotation of the rotation body about its axis χ is movable core 2 efforts zaujat'polohu effect of the centrifugal force with the maximum eccentricity of the structure enabled by the device. when the solenoid 2 is activated by the control voltage, the eccentricity of the rotating sliding core 2 is reduced according to the degree of activation, resulting in a continuously variable kinetic moment and consequently the vibration amplitude is varied from zero to maximum.
