Description
Przedmiotem wynalazku jest przekladnia zebata, wielostopniowa, przeznaczona do uzyskiwania szesnastu róznych, stopniowanych geometrycznie predkosci obrotowych walka biernego, przy jednakowej predkosci obrotowej walka czynnego.The subject of the invention is a gear, multi-stage gear, designed to obtain sixteen different, geometrically graded rotational speeds of the passive combat, at the same speed rotary active combat.
Znane przekladnie zebate wielostopniowe do uzyskiwania szesnastu predkosci obrotowych walka biernego, przy jednej predkosci obrotowej walka czynnego zawieraja piec walków oraz co najmniej czternascie kól zebatych. Na walku czynnym osadzone sa dwa kola zebate, na pierwszym walku posrednim trzy kola zebate, na drugim walku posrednim cztery kola zebate, na trzecim walku posrednim trzy kola zebate a na walku biernym osadzone sa dwa kola zebate. Przekladnie te wymagaja stosowania dlugich walków posrednich, co powoduje zmniejszenie sztywnosci ukladu kinematycznego przekladni.Known multistage gears for achieving sixteen rotational speeds of the fight passive, at one rotational speed the active roll includes five rolls and at least fourteen gear wheels. There are two gear wheels on the active roller, three wheels on the first intermediate roller gears, on the second intermediate roll four gears, on the third intermediate roll three gear wheels and on two gear wheels are mounted in passive roller These transmissions require the use of long intermediate rolls, which reduces the stiffness of the gear kinematic system.
Istota wynalazku polega na tym, ze na walku czynnym osadzone sa przelaczalnie dwa kola zebate wspólpracujace z osadzonymi trwale na pierwszym walku posrednim dwoma kolami zebatymi, natomiast na drugim walku posrednim osadzone sa przelaczalnie cztery kola zebate zgrupowane w dwie pary, z których dwa wspólpracuja z osadzonymi trwale na trzecim walku posrednim dwoma kolami zebatymi, a na walku biernym osadzone sa przelaczalnie dwa kola zebate. Liczby zebów kól zebatych sa tak dobrane, ze szesnascie predkosci obrotowych walka biernego tworzy dwuilorazowy ciag geometryczny, przy czym odchylenia wartosci liczbowych tych predkosci mieszcza sie w przedziale znormalizowanych predkosci obliczeniowych.The essence of the invention lies in the fact that two gear wheels are switchably mounted on the active roller working with two gear wheels permanently mounted on the first intermediate roll, while on in the second intermediate roll, there are switchable four gears grouped in two pairs, two of which cooperate with the permanently seated third intermediate rollers with two gear wheels, and with passive rollers two gear wheels are switchable. The numbers of the teeth of the gear wheels are chosen so that they have sixteen speeds revolving passive combat creates a two-way geometric sequence, with value deviations numerical values of these speeds fall within the range of normalized calculation speeds.
Proponowane rozwiazanie umozliwia uzyskiwanie szesnastu predkosci obrotowych za pomoca dwunastu kól zebatych, przy czym na pierwszym, drugim, czwartym i piatym walku przekladni osadzone sa tylko po dwa kola zebate, na skutek czego walki te sa krótsze od stosowanych w dotychczasowych przekladniach zebatych, co zwieksza sztywnosc lancucha kinematycznego przekladni i umozliwia zmniejszenie \e] gabarytów.The proposed solution enables to obtain sixteen rotational speeds by means of twelve gear wheels, with only two gears on the first, second, fourth and fifth gears gear wheels, as a result of which the fights are shorter than those used in the previous gears, which increases the stiffness of the kinematic chain of the gear and allows for a reduction in overall dimensions.
Jednoczesnie uklad kinematyczny proponowanego rozwiazania umozliwia uzyskiwanie duzych przelozen zmniejszajacych miedzy walkiem czynnym i biernym przekladni.At the same time, the kinematic system of the proposed solution makes it possible to obtain large ratios between the active and passive combat of the gear.
Przedmiot wynalazku uwidoczniony jest w przykladzie wykonania na rysunku, na którym fig. 1 ¦ przedstawia schemat kinematyczny przekladni zebatej, a fig. 2 — wykres predkosci obrotowych.The subject of the invention is illustrated in an exemplary embodiment in the drawing in which Fig. 1 ¦ shows a kinematic diagram of a gear and Fig. 2 shows a diagram of rotational speeds.
Przekladnia wedlug wynalazku sklada sie z walka czynnego 1, na którym osadzone sa przesuwnie dwa kola zebate 2 i 3, pierwszego walka posredniego 4, na którym osadzone sa trwale dwa kola zebate 5 i 6,2 95 249 drugiego walka posredniego 7, na którym osadzone sa przesuwnie cztery kola zebate 8, 9, 10, 11, stanowiace dwie pary kól, trzeciego walka posredniego 12, z osadzonymi na nim trwale dwoma kolami zebatymi 13, 14 i walka biernego 15, na którym osadzone sa przesuwnie dwa kola zebate 16, 17. Kazde z kól zebatych 5 i 6 osadzonych na pierwszym walku posrednim 4, zazebia sie z jednym z kól zebatych 2, 3 osadzonych na walku czynnym 1 oraz z jednym z kól zebatych 8, 9 osadzonych na drugim walku posrednim 7, zas kazde z kól zebatych 13, 14 osadzonych na trzecim walku posrednim 12, zazebia sie z jednym z kól zebatych 10, 11 osadzonych na walku posrednim 7 oraz z jednym z kól zebatych 16, 17 osadzonych na walku biernym 15.The gear according to the invention consists of an active roller 1 on which two are slidably mounted gears 2 and 3, first intermediate gear 4, on which two gears 5 and 6.2 are permanently mounted 95 249 the second intermediate gear 7, on which four gear wheels 8, 9, 10, 11 are slidably mounted, constituting two pairs of wheels, the third intermediate wheel 12, with two gears 13, 14 permanently mounted on it and the passive combat 15, on which are slidably mounted two gear wheels 16, 17. Each of the gear wheels 5 and 6 on the 1st intermediate roller 4, mesh with one of the gears 2, 3 on the roller active 1 and with one of the gear wheels 8, 9 mounted on the second intermediate roller 7, and each wheel gear 13, 14 mounted on the third intermediate roll 12, mesh with one of the gear wheels 10, 11 mounted on an intermediate roller 7 and with one of the gear wheels 16, 17 mounted on the idle roller 15.
Odleglosci miedzy kolami zebatymi 5, 6 osadzonymi na pierwszym walku posrednim 4 oraz kolami zebatymi 13, 14 osadzonymi na trzecim walku posrednim 12 sa tak dobrane, zew srodkowych polozeniach kól zebatych 2, 3 osadzonych na walku czynnym 1 oraz kól zebatych 8,9 i 10,11 osadzonych na drugim walku posrednim 7, jak równiez kól zebatych 16, 17 osadzonych na walku biernym 15, zadne z kól zebatych przekladni nie jest zazebione.The distances between the gears 5, 6 mounted on the 1st intermediate roller 4 and the gears 13, 14 mounted on the third intermediate roller 12 are selected in such a way that from the center positions of the gears 2, 3 mounted on the active roller 1 and gear wheels 8, 9 and 10.11 mounted on the second intermediate roller 7, as well as the gear wheels 16, 17 mounted on the idler 15, none of the gear wheels of the gear is overlapped.
