Abstract
Urządzenie do pomiaru wysunięcia tłoczyska siłownika hydraulicznego zwłaszcza dużego, w którym wewnątrz zamkniętej obwodowej komory utworzonej pomiędzy rurą (1) cylindra, przegrodą (2) zamykającą komorę roboczą od strony tłoczyska (3) a osadzoną przesuwnie na tłoczysku i ciasno w cylindrze (1) pokrywą (4) zaopatrzoną w pierścień zgarniający (5) i pierścień uszczelniający (6), które umieszczone są w obwodowych rowkach odpowiednio na wewnętrznej i zewnętrznej powierzchni walcowej pokrywy (4), która zamocowana jest do przegrody (2), do wewnętrznej powierzchni tej pokrywy (4) przymocowany jest sztywno korpus (8) z dwoma ramionami o różnej grubości, przy czym w grubszym ramieniu wykonany jest cylindryczny otwór o osi w płaszczyźnie prostopadłej do osi cylindra, w którym to otworze osadzona jest mniejszym czopem i zamocowana sztywno za pomocą nakrętek (9) oś (10), z dwoma walcowymi czopami o różnych średnicach, zaś na większym czopie osi (10) osadzone są dwa łożyska toczne (12), na których osadzona jest rolka (13) z amagnetycznego materiału, korzystnie poliamidu, zabezpieczona przed zsunięciem z łożysk, a w centralnej części czołowej powierzchni rolki (13) ukształtowane jest wgłębienie, w którym osadzony jest trwały magnes (16), naprzeciwko którego do czoła drugiego ramienia korpusu (8) sztywno przymocowana jest płytka drukowana (17), połączona z hermetycznym złączem kablowym (19) umieszczonym w pokrywie (4). Wariantowo oś (10) urządzenia posiada czop środkowy, wykonany jako mimośrodowy o niewielkim mimośrodzie, a rolka (13) umieszczona jest w tulei (15) wykonanej z olejoodpornego sprężystego tworzywa korzystnie gumy.A device for measuring the extension of the piston rod of a hydraulic cylinder, especially a large one, in which inside a closed peripheral chamber formed between the cylinder tube (1), a partition (2) closing the working chamber on the piston rod (3) side and a cover slidably mounted on the piston rod and tightly fitted in the cylinder (1) (4) provided with a scraper ring (5) and a sealing ring (6), which are placed in circumferential grooves on the inner and outer surface of the cylindrical cover (4), respectively, which is attached to the partition (2), to the inner surface of this cover ( 4) a body (8) with two arms of different thickness is rigidly attached, while a cylindrical hole is made in the thicker arm with an axis in a plane perpendicular to the cylinder axis, in which a smaller pin is mounted and rigidly fixed with nuts (9). ) axle (10), with two cylindrical journals of different diameters, and on the larger axle journal (10) there are two rolling bearings (12), on which a roller (13) made of an amagnetic material, preferably polyamide, is planted, secured against sliding off the bearings, and in the central part of the front surface of the roller (13) there is a recess in which a permanent magnet (16) is mounted, against which to the face of the second body arm ( 8), the printed circuit board (17) is rigidly attached, connected to the hermetic cable joint (19) located in the cover (4). As a variant, the axis (10) of the device has a central pin, made as an eccentric pin with a small eccentricity, and the roller (13) is housed in a sleeve (15) made of an oil-resistant elastic material, preferably rubber.
