Description
vládač na ovládanie nastavitelných prvkov, hlavně hydraulických ventilov poínohospodárskych traktorov.controller for controlling the adjustable elements, especially the hydraulic valves of agricultural tractors.
Otočný pružný ovládač sa skládá zo skrutkovicovej skrutovej pružiny, nástrčky a rukováti. Skrutkovicová skrutná pružina, montovaná s osovým i obvodovým predpatím je jedným koncom připevněná k vodiacemu čapu nástrčky a druhým k vodiacemu čapu rukovati. Vodiace čapy nástrčky a rufcováti sú opatřené kanálikmi v tvare skrutkovice, zakončené otvormi, do ktorých zapadajú příslušné konce skrutkovicovej skrutnej pružiny. Nástrčka má otvor a skrutku s poistnou maticou na zaistenie ovládača na nastavitetnom prvku.The rotary spring actuator consists of a helical coil spring, a plug and a handle. A helical coil spring, mounted with an axial and circumferential bias, is attached at one end to the guide pin of the plug and the other to the guide pin of the handle. The guide pins of the plug and the grippers are provided with helical channels, terminated with holes in which the respective ends of the helical coil spring fit. The plug has a hole and a screw with a lock nut to secure the actuator on the adjustable element.
Predmetom vynálezu je otočný pružný ovládaě na ovládanie nastavitelných prvkov, hlavně hydraulických ventilov polnohospodárskych traktorov.SUMMARY OF THE INVENTION The subject of the invention is a rotatable flexible actuator for actuating adjustable elements, in particular hydraulic valves of agricultural tractors.
Doposial sú na ovládanie hydraulických ventilov používané ovládače tuhé (neohybnéj alebo zložené (kíbové).Until now, rigid (stationary or folded) controls have been used to control hydraulic valves.
Uvedené nevýhody odstraňuje vynález, ktorého podstata spočívá v tom, že otočný pružný ovládač sa skládá zo skrutkovicovej skrutovej pružiny, nástrčky a rukovati. Skrutkovicová skrutová pružina, montovaná s osovým i obvodovým predpátím, je jedným koncom připevněná k vodiacemu čapu nástrčky a druhým k vodiacemu čapu rukovati. Vodiace čapy nástrčky a rukovati sú opatřené kanálikmi v tvare skrutkovice, zakončené otvormi, do ktorých zapadajú příslušné konce skrutkovicovej skrutnej pružiny. Nástrčka má otvor a skrutku s poistnnu maticou na zaistenie ovládača na nastavitelnom prvku.These disadvantages are overcome by the invention, which consists in the fact that the rotary spring actuator consists of a helical coil spring, a plug and a handle. A helical coil spring, mounted with axial and circumferential biasing, is attached at one end to the pin guide and the other to the handle guide pin. The guide pins of the plug and handle are provided with helical channels, terminated with holes in which the respective ends of the helical coil spring fit. The plug has a hole and a screw with a lock nut to secure the actuator to the adjustable element.
Výhodou tohoto riešenia je možnost’ vyhnutia pružného ovládača vzhladom k ťažko přístupnému miestu umiestnenia nastavitelných prvkov a jeho vzdialenosti od rukovati ovládača. Otočný pružný ovládač je lačnější a výrobně jednoduchší a pri správnej volbě počtu vinutí pružiny účinné zabraňuje poškodeniu nastavitelných prvkov pri výskyte velkých bočných sil.The advantage of this solution is the possibility of avoiding the flexible actuator due to the hard-to-reach location of the adjustable elements and its distance from the handle of the actuator. The swiveling spring actuator is more greedy and simpler to manufacture and, with the correct number of spring windings, effectively prevents damage to the adjustable elements when large lateral forces occur.
Otočný pružný ovládač podía vynálezu je znázorněný na výkrese, kde na obr. 1 je otočný pružný ovládač v osovom řeze, na obr. 2 v řeze A — A podía obr. 1.The rotary flexible actuator of the present invention is shown in the drawing. 1 is a rotary flexible actuator in axial section, FIG. 2 in section A - A according to FIG. First
Otočný pružný ovládač na ovládanie nastavitelných prvkov sa skládá zo skrutkovicovej skrutovej pružiny 1, nástrčky 2 a rukovate 3. Nástrčka 2 má tvar puzdra ukončeného vodiacim čapom. Puzdro nástrčky 2 má otvor, umožňujúci prenášanie krútiaceho momentu a skrutku 4 s poistnou maticou S, ktorá slúži na zaistenie pružného ovládača na nastavitelnou prvku. Rukovať 3 má tvar vaíca s vrúbkovaným povrchom a je tiež zakončená vodiacim čapom. Vodiace čapy nástrčky 2 i rukovati 3 majú kanáliky 6 v tvare skrutkovice, zakončené otvormi 7. Skrutkovicová skrutová pružina 1 je jedným koncom připevněná k vodiacemu čapu nástrčky 2 a druhým koncom připevněná k vodiacemu čapu rukovati 3. Aby bola zaistená požadovaná tuhost pružného ovládača je skrutkovicová skrutová pružina 1 montovaná s osovým i obvodovým predpátím a příslušné konce pružiny 1 sú zasunuté do otvorov 7, čo bráni natáčaniu pružiny 1 pri natáčaní ovládača na niektorú stranu, zatial čo počiatočné zovretie a příslušný počet vinutí vytvára treciu západková brzdu, v důsledku čoho nemůže dójsť ik vyšmyknutiu pružiny 1 z nástrčky 2 a rukovati 3.The rotary flexible actuator for actuating the adjustable elements consists of a helical coil spring 1, a socket 2 and a handle 3. The socket 2 has the form of a sleeve terminated by a guide pin. The socket housing 2 has a bore for transmitting torque and a screw 4 with a lock nut S, which serves to secure the flexible actuator to the adjustable element. The handle 3 has a cam-shaped shape with a notched surface and is also terminated by a guide pin. The guide pins of the plug 2 and the handle 3 have helical channels 6 terminated in the openings 7. The helical coil spring 1 is fixed at one end to the guide pin of the plug 2 and the other end fastened to the guide pin of the handle 3. The screw a coil spring 1 mounted with axial and circumferential bias and the respective ends of the spring 1 are inserted into the holes 7, preventing the spring 1 from pivoting when the actuator is turned to one side, while the initial clamping and the respective number of windings also to slide the spring 1 out of the socket 2 and handle 3.
