Description

Zespól dzwignia 4 - sprezyna agrafkowa 5 ma tylko dwa polozenia równowagi stalej na zderzakach 8 i 9.Zespól ten wspólpracuje z obejma 3 z duzym luzem i dlatego w czasie przestawiania dzwigni 4 nastepuje w pierwszej fazie ruchu jedynie zmiana kierunku dzialania sily. W drugiej fazie, po wykasowaniu luzów w otwo¬ rze 6 odbywa sie przemieszczenie obudowy czujnika 2 az do oparcia obejmy 3 na drugim zderzaku. Zastosowanie80 217 3 duzego luzu daje zdecydowana zmiane polozenia ukladu dzwigniowo-sprezynowego iw konsekwenqi pewnosc, ze nawet przy bardzo malym przemieszczeniu, uchwyt czujnika nie przestawi sie samoczynnie z jednego skrajnego polozenia w drugie pod wplywem ubocznych czynników, na przyklad drgan. Wartosc przemieszczenia wzorcowego ustala sie odlegloscia pomiedzy zderzakami 8 i 9 która moze byc zmieniana przez wkrecenie lub wykrecenie zderzaka nastawnego 9. Przemieszczenie obudowy czujnika 2 powoduje zmiane polozenia wzgledem nieruchomego w tym przypadku rdzenia ferromagnetycznego 10, a wiec zmiane sygnalu elektrycznego, która mierzona w znany sposób pozwala zarejestrowac charakterystyke statyczna czujnika.W odmianie konstrukcyjnej uchwytu osiaga sie wzorcowe przemieszczenie L przez wywarcie nacisku na tuleje posrednia 19. Zostaje wykasowany wzorcowy luz L pomiedzy plytka 18 i wkretka 16, co powoduje wzorcowe przemieszczenie czola czujnika indukcyjnego 26 w stosunku do zwory magnetycznej 27. Zwolnienie nacisku na tuleje posrednia 19 wywoluje jej ruch powrotny i docisniecie plytki 18 do czola kryzy 14, pod wplywem sily sprezystosci napietej sprezyny srubowej 24. Role zderzaków 8 i 9 spelniaja powierzchnie czolowe wkretki 16 i kryzy 14, przy czym zamiane luzu wzorcowego L uzyskuje sie stosujac pierscienie dystansowe. 15 o róznych wysokosciach. PL PLThe lever 4 - spring 5 assembly has only two positions of constant equilibrium on the buffers 8 and 9. This assembly cooperates with the clamp 3 with a lot of play, and therefore when the lever 4 is moved, only the direction of the force changes in the first phase of movement. In the second phase, after the clearances in the opening 6 are removed, the sensor housing 2 is moved until the clamp 3 rests on the second bumper. The use of a large clearance 80 217 3 gives a significant change in the position of the lever-spring system and, consequently, the certainty that even with a very small displacement, the sensor holder will not automatically change from one extreme position to the other due to secondary factors, for example vibration. The value of the reference displacement is determined by the distance between the bumpers 8 and 9, which can be changed by screwing in or unscrewing the adjustable bumper 9. The displacement of the sensor housing 2 causes a change of position in relation to the in this case immobile ferromagnetic core 10, and thus a change of the electric signal, which is measured in a known manner allows to record the static characteristics of the sensor. In the design variant of the holder, the model displacement L is achieved by exerting pressure on the intermediate sleeves 19. The model clearance L between the plate 18 and the screw 16 is erased, which causes the model displacement of the face of the inductive sensor 26 in relation to the magnetic armature 27. Releasing the pressure on the intermediate sleeve 19 causes its return movement and pressing the plate 18 against the face of the flange 14, under the influence of the spring force of the tensioned coil spring 24. The roles of the stops 8 and 9 are performed by the front surfaces of the screw 16 and the flanges 14, whereby the replacement of the reference clearance L is achieved using distance rings. 15 of different heights.
