Description
Przedmiotem wynalazku jest przegub kulisty do pomp i silników hydraulicznych, w szczególnosci zas do promie- niowo-tlokowych mimosrodowych pomp i silników hydra¬ ulicznych.The present invention relates to a ball joint for pumps and hydraulic motors, especially to the radius of piston-piston eccentric pumps and hydraulic motors street lights.
W dotychczas znanych pompach i silnikach hydraulicz¬ nych, a szczególnie w mimosrodowych pompach promie- niowo-tlokowych, w celu obnizenia nacisków stykowych w polaczeniu tlok-mimosród stosuje sie zaopatrzone w gnia¬ zdo trzewiki, wykonane z brazu. Gniazdo to, wykonane zazwyczaj jako wycinek kuli wspólpracuje z kulistym za¬ konczeniem stalowego tloka przy czym docisk tych dwóch powierzchni kulistych jest utrzymywany za pomoca wspól¬ osiowej z tlokiem sprezyny walcowej.In the previously known hydraulic pumps and motors and especially in eccentric radiator pumps piston-piston, in order to reduce the contact pressure in the piston-eccentric combination, a cavity provided is used with ankle boots, made of bronze. The socket is made usually it works with a spherical shape as a segment of a sphere end of a steel piston with the pressure of the two the spherical surfaces is held by a joint axial with cylindrical spring piston.
Jezeli, co nalezy do czestych przypadków, nastapi zatarcie tloka lub pekniecie sprezyny, kontakt pomiedzy kulistym zakonczeniem tloka a gniazdem trzewika zostaje przerwany.If, as is often the case, obliteration occurs piston or spring breakage, contact between the ball end of the piston and the seat of the shoe is broken.
Powoduje to, spotegowane dodatkowo luzami obwodowymi trzewików na tarczy mimosrodowej, przesuniecie osi gniazda w stosunku do osi tloka. Stanowi to istotna wade opisanego wyzej rozwiazania, poniewaz po usunieciu zatarcia i wzno¬ wieniu pracy pompy, kuliste zakonczenie tloka nie trafia w gniazdo powodujac uszkodzenie trzewika.This causes additional circumferential clearances shoes on the eccentric disc, shift of the seat axis in relation to the axis of the piston. This is a significant disadvantage of the described one the above solutions, because after removing the seizure and rising pump, the spherical end of the piston misses into the socket causing damage to the shoe.
W celu usuniecia wyzej opisanych niedogodnosci do¬ tychczasowych rozwiazan postawione zostalo wymagajace rozwiazania zagadnienie techniczne, polegajace na opraco¬ waniu nowego polaczenia tlok-mimosród, które to pola¬ czenie zapewni stale, niezmienne pokrywanie sie osi tloków pompy z osia gniazd poszczególnych trzewików usytuowa¬ nych na tarczy mimosrodowej pompy.In order to overcome the above-described inconvenience to for the timeframe solutions were demanding solutions, the technical issue, consisting in the development a new piston-eccentric connection, which are the fields The connection will ensure a constant and unchanging alignment of the piston axis the pumps with the axis of the seats of individual shoes are located on the eccentric disk of the pump.
Cel ten osiagniety zostal dzieki przegubowi kulistemu wedlug wynalazku, którego istota polega na wykonaniu w tloku, otworu przeznaczonego na trzpien prowadzacy, zamocowany w geometrycznym srodku gniazda trzewika pompy, przy czym dlugosc trzpienia prowadzacego jest wieksza od skoku tloka a mniejsza od podwojonego pro¬ mienia zakreslajacego czasze kulista gniazda trzewika. Takie skojarzenie podanych srodków technicznych zapobiega uszkodzeniom trzewików pompy na skutek zatarcia tloków w blokach zaworowych, a tym samym zapewnia niezawodna prace pompy.This goal was achieved thanks to a ball joint according to an invention, the essence of which lies in making in the piston, the hole for the guide pin, mounted in the geometric center of the shoe socket pump, the length of the guide pin being greater than the stroke of the piston and less than twice the pro ¬ holding the spherical cup of the shoe seat. Such the combination of the technical measures given prevents damage to pump shoes due to seizure of pistons in the valve blocks and thus ensures a reliable operation pump work.
Przedmiot wynalazku uwidoczniony zostal na rysunku w sposób schematyczny. Jak uwidoczniono na rysunku przegub kulisty wedlug wynalazku sklada sie z tloka 1 i zao¬ patrzonego w gniazdo 2 o ksztalcie czaszy kulistej, trzewika 3 usytuowanego na tarczy 6 mimosrodowej. W geometrycz¬ nym srodku gniazda 2 trzewika 3 pompy jest zamocowany trzpien 4 prowadzacy tlok 1. W tloku 1 jest wykonany otwór 5, w który wchodzi trzpien 4 o nieco mniejszej srednicy niz srednica otworu 5, przy czym os geometryczna tloka 1 stanowi zarazem os geometryczna gniazda 2, a trzpien 4 zabezpiecza przegub kulisty przed niepozadanym prze¬ sunieciem sie osi tloka 1 w stosunku do osi gniazda 2.The subject of the invention is shown in the drawing in a schematic manner. As shown in the figure the ball joint according to the invention consists of a piston 1 and a pin looking at the socket 2 with the shape of a spherical ball, shoe 3 located on the 6 eccentric disk. Geometrically in the center of the seat 2 of the pump shoe 3 is fastened pin 4 guiding the piston 1. The piston 1 is made a hole 5 into which a pin 4 of a slightly smaller size fits diameter than the diameter of the hole 5, the axis being geometric the piston 1 is also the geometric axis of the seat 2 and the pin 4 secures the ball joint against undesirable actuation sliding of the piston axis 1 in relation to the seat axis 2.
