Description
Przedmiotem wynalazku jest elektromagnes pra¬ du stalego sluzacy do sterowania, na przyklad roz¬ dzielaczy hydraulicznych.W znanych dotychczas rozwiazaniach konstruk¬ cyjnych zwora trzpieniowa posiada jedna powie¬ rzchnie czolowa prostopadla do osa zwory, czynna magnetycznie jak na przyklad elektromagnesy we¬ dlug opisów patentowych Wielkiej Brytanii 1265848 i ia7B04i6.Znane sa równiez rozwiazania posiadajace jedna powierzchnie czynna magnetycznie uksztaltowana sfozkowo jak wedlug opiisu patentowego Wielkiej Brytanii 12&8858 lub jak w opisie patentowym Pol¬ skim 6,4|583. dstota elektromagnesu pradu stalego wedlug wy¬ nalazku polega na tym, ze ' jego trzpieniowa zwo¬ ra zaopatrzona jest na obu koncach w powierz¬ chnie stozkowe uksztaltowane wspólbieznie lub przeciwbieznie.Wprowadzenie dwóch powierzchni czolowych magnetycznie czynnych, uksztaltowanych stozkowo umozliwia zwiekszenie czynnej sily elektromagne¬ su w danym przekroju obwodu magnetycznego na skutek zwiekszenia czynnego przekroju w szczeli¬ nach magnetycznych i w efekcie tego uzyskanie wiejkszej sily startowej. Zostaje równiez stworzona mozliwosc uzyskania róznych charakterystyk si¬ lowych elektromagnesu w zaleznosci od uksztalto¬ wania katów obu powierzchni stozkowych i wza¬ jemnego ich polozenia. 2 Przedmiot wynalazku jest przedstawiony w przy¬ kladzie wykonania na rysunku w przekroju wzdlu- znymr Elektromagnes sklada sie z obudowy 1, osadzo¬ nych w niej pierscieni 2 i 3 zaopatrzonych w po¬ wierzchnie stozkowe 4' i 5', cewki 6 osadzonej po¬ miedzy pierscieniami 2 i 3, trzpieniowej zwory 7 zaopatrzonej w dwie powierzchnie stozkowe 4 i 5 i osadzonej przesuwnie w otworze 8, pierscienia 2, przy czym powierzchnie 4 i 5 moga byc uksztalto¬ wanie jalko powierzchnie wspólbiezne lub przeciw¬ biezne jak w przykladzie wykonania na rysunku.W trzpieniowej zworze 7 osadzony jest trzpien 9, na którym umieszczona jest dystansowa pod¬ kladka 10. Obudowa 1 zamknieta jest elementem 11, w którym umieszczony jest elastyczny zderzak 12. pewka 6 zasilona pradem wywoluje strumien magnetyczny £, którego przebieg w obwodzie ma- gneitycznym jest pokazany na rysunku linia prze¬ rywana. Trzpieniowa zwora 7 przyciagana jest swoimi powierzchniami stozkowymi 4 i 5 do po- wierzchni 4' i 5'. Ruch zwory przekazywany jest przez trzpien 9 na element wspólpracujacy z ele¬ ktromagnesem az do styiku powierzchni 13 z dys¬ tansowa podkladka 10, co powoduje zamkniedie ob¬ wodu magnetycznego. Dystansowa podkladka 10 ustala minimalna szczeline powietrzna pomiedzy 99 18299 182 powierzchniami stozkowymi 4—4' i 5—5', która po¬ woduje zmniejszenie sil koercjd magnetycznej przy wylaczaniu.Po wylaczeniu zasilania cewki 6 nastepuje ruch powrotny trzpieniowej zwory 7 na skutek dziala¬ nia na trzpien 9 elementu wspólpracujacego z ele¬ ktromagnesem, badz pod wplywem sily grawita¬ cji. Trzpieniowa zwora 7, w polozeniu przy wy¬ laczonym zasilaniu cewki 6, opiera sie o elasty¬ czny zderzak 12. PLThe subject of the invention is a direct current electromagnet used to control, for example, hydraulic distributors. In the previously known design solutions, the spindle armature has one front surface perpendicular to the axis of the armature, active magnetically, such as electromagnets according to patents Great Britain 1265848 and ia7B04i6. There are also known solutions having one active surface magnetically shaped like a frog, as according to the British patent description 12 & 8858 or as in the Polish patent 6.4 | 583. According to the invention, the essence of a direct current electromagnet is that its spindle armature is provided at both ends with conical surfaces shaped jointly or in opposite directions. in a given cross-section of the magnetic circuit as a result of an increase in the active cross-section in the magnetic gaps and, as a result, obtaining a greater starting force. It is also possible to obtain different force characteristics of the electromagnet depending on the shape of the angles of both conical surfaces and their mutual location. 2 The subject of the invention is presented in an exemplary embodiment in a longitudinal section of the drawing. The electromagnet consists of a housing 1, rings 2 and 3 embedded in it, provided with conical surfaces 4 'and 5', a coil 6 embedded in between the rings 2 and 3, the spindle armature 7 provided with two conical surfaces 4 and 5 and slidably seated in the opening 8, rings 2, the surfaces 4 and 5 may be shaped as concurrent or opposite surfaces as in the example of the embodiment on In the spindle armature 7 there is a mandrel 9, on which a spacer 10 is placed. The housing 1 is closed by an element 11, in which a flexible stopper 12 is placed. The pivot 6, when energized, causes a magnetic flux a broken line is shown in the drawing. The spindle armature 7 is attracted with its tapered surfaces 4 and 5 to the surfaces 4 'and 5'. The movement of the armature is transmitted through the pin 9 to the element cooperating with the electromagnet until the contact surface 13 with the spacer 10, which causes the closing of the magnetic circuit. The spacing washer 10 establishes a minimum air gap between the taper surfaces 4-4 'and 5-5', which reduces the magnetic coercive force when switching off. When the coil 6 is turned off, the pin armature 7 is retracted by operation on the pin 9 of the element cooperating with the electromagnet, be under the influence of the force of gravity. The pivot armature 7, in position with the coil 6 turned off, rests against the flexible stop 12. EN
