Abstract
Vynález sa týká pirevedenia synchrónnej pohonnej jednotky so záťažou. Vynález rieši rozběh synchrónnej pohonnej jednotky so záťažou v správnom smere. Podstata vynálezu spočívá v tom, že náboj záťaže je na unášači pohonu uložený pružné.The invention relates to a design of a synchronous drive unit with a load. The invention solves the starting of a synchronous drive unit with a load in the correct direction. The essence of the invention lies in the fact that the load hub is mounted elastically on the drive carrier.
Description
Vynález sa týká zhotovenia zariadenia pre rozběh syindhránnej pohonnej jednotky so záťažou, ktorej celkový moment zotrvačnosti je vačší ako je dovolený pre rozběh.The invention relates to the construction of a device for starting a syindrated drive unit with a load whose total moment of inertia is greater than allowed for starting.
V isúčasnej doibe sa používajú synchronně pohonové jednotky s elektrickým vymedzením zmyislu točenia, například na otáčanie cloniiek bezdotykových snímačov. Clonky spolu s uinášačom sú upevněné priamo na hriadeli synchrónnej pohonnej jednotky. Ak má unášač spolu s ólonfcamii vačší moment zotrvačnolsiti, ako je pre rozběh dovolený, tak synchrónna pohonová jednotka po spustení sa buď neroiztočí, alebo sa roztočí v spirávnom, připadne v nesprávnom smere.In the present doibe, synchronous drive units are used with an electric rotation limiter, for example, to rotate the screens of proximity sensors. The screens together with the uinášačom are mounted directly on the shaft of the synchronous drive unit. If the carrier together with the solver has a greater moment of inertia than is allowed for start-up, the synchronous drive unit after start-up either does not rotate or rotates in the right direction or falls in the wrong direction.
Vyšišíe uvedené nedostatky odstraňuje zairiadenie pre rozběh synchrónnej pohonnej jednotky soi záťažou, podl’a vynálezu, ktorého podstatou je, že náboj je na unášači uložený prositredníctvom skrutnej pružiny.The above-mentioned drawbacks are eliminated by the apparatus for starting the synchronous drive unit under load, according to the invention, which is based on the fact that the hub is mounted on the carrier by means of a helical spring.
Zariadením podl’a vynálezu sa docieli toho, že moment zotrvačnosti záťaže rotora synchrónnej pohonovej jednotky s elektricky vyimedzeným zmyslom točenia v okamžiku spusiemia jednotky nepřekračuje dovolenú hodnotu pre rozběh vo vymedzenom zmyisle točenia. Preto sa jednotka roztočí vždy v sípirávnom smere.By the device according to the invention it is achieved that the moment of inertia of the load of the rotor of the synchronous drive unit with the electrically excited sense of rotation at the moment of starting the unit does not exceed the allowable value for starting in the defined rotation error. Therefore, the unit always rotates in the right direction.
Na připoj enom výkrese je nakreslené příkladné Zhotoveniie zariadenia v řeze.An exemplary cross-sectional embodiment of the device is shown in the accompanying drawing.
Zariadenie pre rozběh synchrónnej pohonovej jednotky so záťažou, ktorej moment zotrvačnosti je vačší ako je pre rozběh dovolený, pozostáva z vlastnej synchrónnej pohonovej jednotky 1, ktorej hriadel’ 6 je pevne opatřený unášačom 2. Na unášači 2 je otočné uložený náboj 4. Unášač 2 je spojený s nábiojorni 4 proistredníctvom skrutnej pružiny 3. Na náboji 4 sú pevne uchytené dve clony 5.A device for starting a synchronous drive unit with a load whose moment of inertia is greater than that allowed for starting consists of the synchronous drive unit 1 itself, the shaft 6 of which is fixedly provided with a carrier 2. A carrier 4 is rotatably mounted on the carrier. connected to the hubs 4 by means of a torsion spring 3. Two orifices 5 are fixed to the hub 4.
V okamihu .spuistemia synchrónnej pohono vej jednotky 1 sa záčne otáčať súčasne s hriadel’om 6 unášač 2 v správnom smere točenia. Siúčasne sa začne napínať skirutná pružina 3, ktorá pri určáitom napnutí začne otáčať aj náboj 4 s clonkou 5 rovnakou uhlovou rýchiosťoiu, ako sa otáča ihriade! 6 syndhróninej pohon,nej jednotky s unášačom 2.At the time of the synchronous drive unit spuistemia 1, it rotates at the same time as the shaft 6 of the carrier 2 in the correct direction of rotation. At the same time, a tension spring 3 starts to tension, which at a certain tension also starts to rotate the hub 4 with the orifice 5 at the same angular velocity as that of the shaft! 6 Syndrome drive, its drive unit 2.
