Description

Przedmiotem wynalazku jest mechanizm napedowy bebna mieszarki, w której obrotowy moment napedowy jest wprowadzony do bebna przy dnie tego bebna, wyposa¬ zonej do kompensacji sil skrecajacych wystepujacych po¬ miedzy bebnem a elementami podpierajacymi obudowe bebna.W mechanizmach napedowych bebnów mieszarek wyla¬ nia sie problem tego rodzaju, iz z jednej strony musi byc przenoszony stosunkowo duzy moment obrotowy, a z dru¬ giej strony wystepuja dosc duze sily skrecajace pomiedzy elementami podpierajacymi beben i obciazonymi ponadto ciezarem przekladni napedowej itp. a sama obudowa beb¬ na. Ponadto mieszarki sa eksploatowane w dosc trudnych warunkach, co takze ma wplyw na mechanizm napedowy.Dotychczas nie znaleziono rozwiazania które by moglo zadosc uczynic wszystkim stawianym wymaganiom. Jezeli stosuje sie naped calkowicie obudowany, to przy jego wysokich kosztach istnieja takze powazne trudnosci w przypadku malych wymiarów ograniczonychwielkoscia obudowy, we wlasciwym przenoszeniu momentów nape¬ dowych. Jezeli natomiast na obudowie bebna zamontuje sie wieniec zebaty o stosunkowo w tym przypadku duzej srednicy to przenoszone sily beda wprawdzie mniejsze, lecz wystapia trudnosci we wlasciwym obudowaniu tego napedu.Zgodnie z przedmiotowym wynalazkiem opracowano mechanizm napedowy bebna mieszarki szczególnie uzyte¬ czny w przypadku wystepowania duzychmomentów obro¬ towych. W mechanizmie tym wystepujace sily skrecajace nie oddzialywuja juz niekorzystnie na poszczególne czesci przekladni a ponadto mozliwe jest zamkniecie w obudowie wszystkich elementów napedu.Przedmiot wynalazku zgodnie z podanymi na wstepie uwagami rozwiazano w ten sposób, iz symetrycznie do osi bebna jest przymocowany do jego obudowy pierscieniowa obejma, w której z pewnym odstepem umieszczony jest pierscieniowy czlon napedowy bebna, zas pozostala szcze¬ lina pierscieniowa jest wypelniona elastycznym materia¬ lem, który mocno przylega do sasiadujacych powierzchni przejmujac sily skrecajace, a w czlonie napedowym znaj¬ duje sie co najmniej jedna czesc przekladni napedowej.Zgodnie z rozwiazaniemwedlug wynalazkuczesci maja¬ ce wplyw na wyrównanie sil skrecajacych, maja takze za zadanie przenoszenie momentu obrotowego. Stwierdzono bowiem, iz jest to mozliwe przy odpowiednio duzej sredni¬ cy bez nadmiernego oddzialywania na elastyczny material a takze bez wystepowania zbyt duzych sil skrecajacych.Dzikeki temu, iz czlon napedowy zawiera w sobie istotna czesc przekladni, stalo sie mozliwe calkowite zamkniecie w obudowie przekladni, uzyskujac przy tym zwarta kon¬ strukcje.Jest takze korzystne, gdy zwrócone ku sobie powierzch¬ nie pierscieniowej obejmy oraz 'czlonu napedowego maja ksztalt kulisty. Wystarczy zreszta, jezeli ten ksztalt kulisty bedzie wykonany czesciowo lub chocby w przyblizeniu.Pierscieniowa szczelina pomiedzy czlonem napedowym a pierscieniowa obejma bedzie wypelniona elementami z materialu elastycznego. Zgodnie z wynalazkiem ma byc jednak wypelniona cala szczelina tylko jednym tworzy¬ wem z elastycznego materialu, przy czym tworzywo to 9148591485 3 laczL pierscieniowa szczeline i czlon napedowy w sposób bardziej lub mniej ruchomy.Rozwiazanie wedlug wynalazku, zgodnie z którym prze¬ noszenie momentu obrotowego ma sie odbywac za pomoca elastycznego tworzywa, mozna zastapic przez zastosowa¬ nie urzadzenia zabierakowego zainstalowanego pomiedzy pierscieniowa obejma i czlonem napedowym, na przyklad w postaci sworznia zabierakowego lub tym podobnego urzadzenia. Lepszym rozwiazaniemjestjednak przenosze¬ nie calkowitego momentu obrotowego za posrednictwem elastycznego materialu.W wypróbowanym juz i sprawdzonym rozwiazaniu we¬ dlug wynalazku czlon napedowy jest wyposazony w we¬ wnetrzny wieniec zebaty wspólpracujacy z kolami zebaty¬ mi usytuowanymi w sposób planetarny, przy czym kola te sa napedzane przez jedno male kolo zebate. Walki plane¬ tarne osadzonych kól zebatych sa ulozyskowane w czesci polaczonej na stale z obudowa przekladni napedowej, tak iz walki te nie kraza wokól siebie. Osadzone na tych walkach kola zebate stanowia polaczenie pomiedzy malym kolem napedowym a wewnetrznym wiencem zebatym i na skutek duzej róznicy srednic malego kola napedowego a wewnetrznym wiencem zebatym uzyskuje sie duze prze¬ lozenie na tym stopniu mechanizmu napedowego. Dalsze uksztaltowanie przedmiotu wynalazku przewiduje, ze czlon napedowy wspiera sie na czesci, wktórej sa osadzone walki kól planetarnych. Dzieki temu uzyskano bezposred¬ nie podparcie czlonu napedowego na obudowie prze¬ kladni.W zwiazku z tym przedmiot wynalazku przewiduje w szczególnosci, iz lozyska czlonu napedowego maja mniejszy promien niz odleglosc pomiedzy walkami kól planetarnych od osi malego kólka napedowego. Mala sred¬ nica lozysk daje te mozliwosc, iz otwarta szczelina piers¬ cieniowa znajdujaca sie pomiedzy czlonem napedowym a obudowa przekladni posiada stosunkowo niewielka srednice,dzieki czemu dokladne uszczelnienie tej szczeliny nie pzedstawia duzej trudnosci. W konsekwencji uzyskano mechanizm napedowy, którego obudowanie nie stanowi zadnych problemów, a który przy tym ma na swoim ostat¬ nim stopniu napedowym bardzo duze przelozenie, zas sily skrecajace ani tez przenoszenie momentu napedowego nie przedstawia zadnych trudnosci.Przedmiot wynalazku jest przedstawiony przykladowo na schematycznym rysunku. Rysunek ten przedstawia czesciowy przekrój przez obudowe bebna i jego elementy napedowe. Beben 19 obraca sie wokól osi 1. W obudowie 2 bebna jest przestrzen 18 utworzona przez pierscien 21 i jego pokrywe 22. W przestrzeni tej znajduje sie pierscie¬ niowa obejma 3 i odpowiednie urzadzenia. Wewnatrzpier¬ scieniowej obejmy 3 umieszczone jest tworzywo 14 zelas¬ tycznego materialu przylegajacego do czlonu napedowego 4. Czlon napedowy 4 wsparty jest poprzez podpory lozy¬ skowe 7 oraz 8 na lozyskach kulkowych 9 i 10, które z kolei 4 sa osadzone w czesci 16 stanowiacej element obudowy przekladni 17. W wymienionej czesci 16 sa równiez ulozy¬ skowane walki 11 planetarnych kól zebatych 12. Lacznie znajduja sie trzy tego rodzaju walki z kolami zebatymi, przy czym ich lozyska kulkowe oznaczone sa na rysunku przez liczbe 23. Zebate kola 12 zazebiaja sie z wewnetrz¬ nym wiencem zebatym 15 czlonu napedowego 4 Na rysunku pokazano zewnetrzna powierzchnie 5 czlo¬ nu napedowego 4 wykonana w ksztalcie kulistym, podczas gdy powierzchnia 6 odbiega juz od ksztaltu kulistego.Obudowa przekladni 17 jest zamocowana na podporze 20. PLThe subject of the invention is the driving mechanism of a mixer drum, in which the rotational driving torque is introduced into the drum at the bottom of the drum, equipped to compensate for the torsional forces occurring between the drum and the elements supporting the drum housing. The problem spills out in the driving mechanisms of the mixing drums. such that, on the one hand, a relatively high torque must be transmitted, and on the other hand, quite high torsional forces occur between the drum support elements and the weight of the transmission gear, etc., and the drum housing itself. In addition, mixers are operated in quite difficult conditions, which also affects the drive mechanism. So far, no solution has been found that would meet all the requirements. If a fully encapsulated drive is used, at its high cost there are also serious difficulties in the case of small dimensions limited by the size of the housing in properly transmitting the driving torques. If, on the other hand, a toothed wheel with a relatively large diameter is mounted on the drum casing, the transferred forces will be smaller, but there will be difficulties in properly enclosing this drive. According to the present invention, the driving mechanism of the mixer drum has been developed, which is particularly useful in the case of the presence of large rotor torque May's. In this mechanism, the torsional forces no longer have a negative effect on the individual parts of the gear, and moreover, it is possible to enclose all the drive components in the housing. in which the ring drive part of the drum is placed with a certain distance, and the remaining ring slit is filled with an elastic material which adheres tightly to the adjacent surfaces to absorb twisting forces, and at least one part of the drive gear is located in the drive unit. According to the solution according to the invention, the components having an influence on the equalization of the torsional forces also have the task of transmitting the torque. It has been found that it is possible with a sufficiently large diameter without excessive impact on the elastic material and also without the occurrence of excessive torsional forces. Due to the fact that the drive unit contains a significant part of the gear, it became possible to completely enclose the gear housing, thereby obtaining a compact structure. It is also advantageous if the facing surfaces of the ring clamp and the drive element have a spherical shape. It is enough, however, if this spherical shape is made partially or even approximately. The ring-shaped gap between the drive member and the ring-shaped clamp will be filled with elements of elastic material. According to the invention, however, the entire gap is to be filled with only one plastic of an elastic material, the material being a ring-shaped joint and a drive member more or less movably. The solution according to the invention, according to which the torque transmission has to take place by means of a flexible material, it can be replaced by using a driving device installed between the ring clamp and the drive member, for example in the form of a driving pin or the like. A better solution, however, is to transmit the total torque by means of an elastic material. In the already tried and tested solution according to the invention, the drive unit is equipped with an internal toothed wheel which cooperates with the planetary gears, the wheels being driven by through one small gear. The planetary battles of the mounted gear wheels are located in a part permanently connected to the gear housing, so that these battles do not circulate around one another. The gears mounted on these fights are the link between the small drive wheel and the inner gear wheel, and due to the large difference in diameter of the small drive wheel and the internal gear wheel a large gear ratio is achieved at this stage of the drive mechanism. A further development of the subject matter of the invention provides that the drive member is supported on the part in which the battles of the planetary wheels are seated. As a result, the drive element is directly supported on the gear housing. The subject of the invention therefore provides, in particular, that the drive unit bearings have a smaller radius than the distance between the planet gear battles from the axis of a small drive pulley. The small diameter of the bearings also gives the possibility that the open ring gap between the drive member and the gear housing has a relatively small diameter, so that the tight sealing of this gap is not difficult. As a result, a drive mechanism was obtained, the housing of which does not pose any problems, and which, at the same time, has a very large gear ratio on its last drive stage, and the torsional forces and torque transmission do not present any difficulties. The subject of the invention is shown, for example, in a schematic drawing. . This drawing shows a partial section through the drum housing and its driving elements. The drum 19 rotates around the axis 1. In the drum casing 2 there is a space 18 formed by the ring 21 and its cover 22. In this space there is a ring-shaped bracket 3 and the corresponding devices. Inside the annular clamp 3 is a plastic 14 of a flexible material adhering to the drive element 4. The drive element 4 is supported by bearing supports 7 and 8 on ball bearings 9 and 10, which in turn 4 are embedded in the part 16 constituting the element. gear housing 17. Said part 16 also arranges the battles of 11 planetary gears 12. In total there are three such battles with gears, where their ball bearings are marked with the number 23 in the figure. The gear wheels 12 mesh with the inner gear 15 of the drive section 4 The figure shows the outer surface 5 of the drive section 4 made in a spherical shape, while the surface 6 already deviates from the spherical shape. The gear housing 17 is mounted on a support 20. EN
