Description

Przedmiotem wynalazku jest urzadzenie do na¬ pinania zespolu pasków, zwlaszcza plaskich i kli¬ nowych pasków napedowych.W przekladniach pasowych o wiekszej ilosci pa¬ sków wystepuje zjawisko nierównomiernego obcia¬ zenia wszystkich pasków, ze wzgledu na niejdna- kowa ich dlugosc poczatkowa i róznice w szyb¬ kosci rozciagania sie podczas przenoszenia napedu.Taki stan rzeczy powoduje podczas przenoszenia mocy obciazenie grupy pasków na granicy wytrzy¬ malosci lub jej przekroczenie, natomiast pozostale, w tym samym czasie, przenosza czesc zalozonej mocy lub pracuja bez obciazenia, skutkiem czego jest zniszczenie wszystkich pasków w krótkim cza¬ sie oraz wystepowanie poslizgów i nierównomier¬ nej pracy przekladni oraz zmniejszenie sprawnosci przelozenia.Znane sa urzadzenia do napinania ipasków skla¬ dajace sie z zamocowanej przesuwnie lub wychyl- nie rolki wyposazanej w sprezyne. Na skutek dzia¬ lania sprezyny rolka opierajac sie o zespól pasków — naciaga je. Ze wzgledu na rózna dlugosc pas¬ ków wchodzacych w sklad zespolu a takze nie¬ równomierne ich trwale rozciaganie sie na skutek eksploatacji, stosowanie znanych urzadzen nie za¬ pewnia jednakowego naciagu kazdego paska. Po¬ wyzsza wada chrakteryzuja sie takze sposoby na¬ pinania zespolu pasków polegajace na przesuwa¬ niu po prowadnicach lub wychylaniu silnika na¬ pedowego. 15 20 25 30 Wymienione wady i niedogodnosci zostaly wyeli¬ minowane w urzadzeniu wedlug wynalazku, które sklada sie z korpusu z zamknietym ukladem cis¬ nieniowym, który stanowia polaczone kanalami cy¬ lindry o jednakowej srednicy, w których sa osa¬ dzone przesuwnie tloki z przytwierdzonymi jarz¬ mami rolek oraz korek regulacyjny.Zaleta tego urzadzenia jest uzyskanie jednako¬ wego naciagu kazdego z zespolu paska, niezaleznie od ich dlugosci poczatkowej oraz stopnia trwalego wydluzenia podczas pracy.' Przedmiot wynalazku zostal uwidoczniony w przykladzie wykonania na rysunku, na którym fig. 1 przedstawia urzadzenie do napinania zespolu pasków w przekroju pionowym, fig. 2 w przekroju poprzecznym, fig. 3 w widoku z góry, a fig. 4 usytuowanie urzadzenia wedlug wynalazku w prze^ kladni pasowej.W korpusie 1 sa usytuowane cylindry 2 o jed¬ nakowej srednicy, w których sa osadzone suwliwie tloki 3 z przytwierdzonymi jarzmami 4 rolek 5.Cylindry 2 sa polaczone kanalami 6, tworzac za¬ mkniety uklad cisnieniowy wyposazony ponadto w zawór 7 odpowietrzajacy i korek 8 regulacyjny.Dzialanie urzadzenia wedlug wynalazku polega na tym, ze zamontowane na ramie przekladni pa¬ sowej urzadzenie poprzez rolki 5 wspólpracuja¬ ce z odpowiadajacymi im paskami 9 przekladni powoduja, na skutek stalego cisnienia we wszyst¬ kich cylindrach 2 oraz stalej powierzchni tloków 3, 113 593113 593 jednakowy ich naciag, którego wielkosc jest regu¬ lowana wkrecaniem lub wykrecaniem korka 8 re¬ gulacyjnego i moze byc ustalana odpowiednio wy- skalowanym manometrem — nieuwidocznionym na rysunku.Dlugosc poczatkowa lub stopien trwalego wydlu¬ zenia sie pasków 9 ma wplyw na polozenie odpo¬ wiadajacych im tloków 3 w cylindrach 2 urza¬ dzenia.Zastrzezenie patentowe Urzadzenie do napinania zespolu pasków, zna¬ mienne tym, ze sklada sie z korpusu (1) z zamknie¬ tym ukladem cisnieniowym, który stanowia po¬ laczone kanalami (6) cylindry (2) o jednakowej srednicy, w których sa osadzone suwliwie tloki (3) z przytwierdzonymi jarzmami (4) rolek (5) oraz korek (8) regulacyjny.ZGK 5, Btm. zam. 9014 — 105 egz.Cena 100 zl PLThe subject of the invention is a device for tensioning a set of belts, especially flat and wedge-shaped drive belts. In belt transmissions with a greater number of belts, there is a phenomenon of uneven load on all belts, due to their initial length and differences in the speed of stretching during transmission of the drive. This state of affairs causes the group of belts to be loaded or exceeded at the breaking point during power transmission, while the others, at the same time, transmit part of the assumed power or operate without load, thereby destroying all belts in a short time and the occurrence of skidding and uneven operation of the gear and reduction of the efficiency of the gear ratio. There are known devices for tensioning and belts consisting of a sliding or tilting roller equipped with a spring. Due to the action of the spring, the roller rests against the set of belts - it stretches them. Due to the different length of the strips included in the assembly and also their uneven and permanent stretching as a result of use, the use of known devices does not ensure the same tension of each strip. The above-mentioned disadvantage is also characteristic of the methods of pinning the belt assembly by sliding it along the guides or tilting the motorized motor. The above-mentioned drawbacks and inconveniences have been eliminated in the device according to the invention, which consists of a body with a closed pressure system, which consists of cylinders of equal diameter connected by channels, in which the pistons are slidably mounted with fixed the roller shackles and the adjusting plug. The advantage of this device is to obtain the same tension on each belt assembly, regardless of their initial length and the degree of permanent elongation during operation. ' The subject matter of the invention is shown in an embodiment in the drawing, in which fig. 1 shows a device for tensioning the belt assembly in a vertical section, fig. 2 in a cross-section, fig. 3 in a plan view and fig. In the body 1 there are cylinders 2 of the same diameter, in which the pistons 3 are slidably mounted with the yokes 4 of the rollers. 5. The cylinders 2 are connected by channels 6, creating a closed pressure system, additionally equipped with a venting valve 7. The operation of the device according to the invention consists in the fact that the device mounted on the belt gear frame, through rollers 5, cooperating with the corresponding gear belts 9, causes, due to the constant pressure in all cylinders 2 and the constant surface of the pistons 3, 113 593 113 593 the same tension, the size of which is regulated by screwing or unscrewing the adjustment plug 8 and can be set on a suitably calibrated manometer - not shown in the figure. The initial length or the degree of permanent elongation of the strips 9 has an influence on the position of the corresponding pistons 3 in the cylinders 2 of the device. Patent claim Device for tensioning the belt unit, specified in that it consists of a body (1) with a closed pressure system, which consists of cylinders (2) of the same diameter connected by channels (6), in which the pistons (3) are slidably mounted with the yokes (4) of the rollers (5) and adjustment plug (8) ZGK 5, Btm. residing 9014 - 105 copies Price PLN 100 PL
