Description
Vynález sa týká diferenoiálneho náhonu zbijaoieho orgánu čelného uholného kombajnu, ktorý umožňuje poháňať jedným silným motorom pomooou viaoerýoh prevodov jeden společný hriadel’, pričom sú zuby posledného zubového převodu na hriadeli zaťažené vždy rovnoměrně a nedfijde k preťaženiu, alebo k zničeniu týohto prevodov ioh nerovnoměrným zaťaženim spfisobeným ioh rozdielnou zubovou vfilou.BACKGROUND OF THE INVENTION The present invention relates to a differential drive of a frontal coal harvester, which allows a single motor to drive one common shaft with multiple gears, with the teeth of the last gear on the shaft always being loaded evenly and not overloaded or destroyed by uneven gears. ioh different tooth vfilou.
Dodnes známe takéto převody boli tuhé a rozdielna zubová vfila posledného stupňa spfisobovala aj ioh rozdielné zaťaženie, v dfisledku čoho došlo k ioh postupnému zničeniu hlavně vtedy, keď tento stupeň nebolo možné dimenzovat’ na oelý motorový výkon pre nedostatek priestoru.To date, such gears have been rigid, and different final gear tooth drives have also been subject to different loads, resulting in even gradual destruction, especially when this gear could not be dimensioned for a lot of engine power due to lack of space.
Uvedené nedostatky odstraňuje tento vynález tým, že jeho hriadel’ je opatřený naklinovaným kotúčom, unášajúoim satelity zapadajúce do tanierovýoh kolies volné otočnýoh na tomto hriadeli a spojených s čelnými zubovými kolesami zapadajúoimi do zubovýoh kolies naklínovaných na hriadeíoch hruškových kolies zapadajúoioh do tanierovýoh kolies naklinovanýoh na spoločnom hriadeli so zbijaoimi valoami.The present invention removes the present invention by providing its shaft with a wedge-shaped disc which carries the satellites engaging the plate wheels free to rotate on the shaft and coupled to the spur gear wheels wedged on the pinion shaft shafts on the wheel shaft. s zbijaoimi valoami.
Výhodou tohoto riešenia je, že sa dá velký motorový výkon preniesť viaoerými prevodmi do malého priestoru, v ktorom nie je možné každý převod dimenzovat’ na inštalovaný motorový výkon tak, aby nedošlo k jeho zničeniu vtedy, keá dfijde k rozdielnej zubovéj vfiliThe advantage of this solution is that large engine power can be transferred by multiple gears to a small space in which each gear cannot be dimensioned for the installed engine power so that it is not destroyed when different toothed worms occur

Na pripojenom výkrese je znázorněný pódorysný rez takého náhonu. Na obraze je příklad takéhoto náhonu s použitím pre pohon zbijacleho orgánu čelného uhelného kombajnu, pričom sa zbíjaoí orgán skládá z hnaoieho elektromotore J., planetového reduktora tvořeného zubovými kolesami 4, ďalej ho tvoří hriadel’ 2 8 naklinovaným kotúčom 29 so satelitní! £, otočnými na čepooh 10. 30. «Solné zubové kolesá 8., 26, pevne spojené s tanierovými kolesami 28. 32 a otočné na hriadeli 2.» éolné zubové kolesá 11 . 27 naklinované na hriadolooh 12 . 24 hruškovýoh kolies 13. 22 zapadajúoioh do tanieřovýoh kolies 15. 20 naklinovanýoh na spoločnom hriadeli 17 a uložených v skriniaoh 16. 19.The attached drawing shows a plan view of such a drive. On the picture is an example of such a drive by using the drive for front body zbijacleho coal combines, wherein the body comprises a zbíjaoí hnaoieho J electric motor, a planetary reducer constituted by gear wheels 4, it also forms a shaft 2 8 keyed wheel 29 to the map? The salt sprockets 8, 26 are rigidly connected to the disc wheels 28. 32 and rotatable on the shaft 2. The oil sprockets 11. 27 wedged on the shaft 12. 24 pear wheels 13. 22 fit into the plate wheels 15. 20 pinioned on a common shaft 17 and housed in cabinets 16. 19.
Počas Činnosti elektromotor £ poháúa hriadelom J zubové koleso 4, a planetové kolesá J, 33. ktoré sa odvalujú po zubovom véno i 6, redukujú tak obrátky a poháúajú hriadel’ 2 a pevným kotúčom 29 a satelitmi <?, 31 . ktorá zapada jú do tanieřovýoh kolies 28, 32 pevne spojených s ozubenými kolesami 26. 8, odkial’ sa krútia o i moment prenáša kolesami 11. 27. hriadeími 12. 24, hruškovými kolesami 13. 22 a tanierovými kolesami 15. 20 na epoločný hriadel 17. na ktorom eú umiestnená zbíjaoie váloe 14. 18. 21 kombajnu. Pokial sú kuželové převody 13. 15 a 22. 20 s rovnakou zubovou vdlou, všetko je v poriadku a obidva sú rovnako zaťažené. V případe, že ale jeden převod má inú zubovú vólu ako druhý, potom převod e raenšou zubovou vdlou ťahá viao, alebo všetko a druhý menej, alebo běží na prázdno, pričom prvý převod súo preťažený celým motorovým výkonom sa vyláme, pretože ho pře stiesnenosť v malom priestore zbíjaoíoh váloov nebolo možné dimenzovat’ na plný motorový výkon a preto museli byť volené dva převody. V tomto případe sa ale preťažený převod pozastaví, spomalí, například je to pravý s ozubeným kolesom 27. 8 a keďže je kotúč 29 stále ťahaný elektromotorom J. a hriadelom 2> začne sa satelite J, 31 odvalovat’ po tanierovom kolese 32. jej obrátky sa prenesú na tanierové koleso 28, pevne spojené s kolesom 26 a kolesom 11. hriadelom 12 na hruškové koleso 13. ktoré tak získá obrátky, vlastně len pohyb přenesený satelitami z pravého převodu, čím sa zubová vÓl’a medzi hruškovým kolesom 13 a tanierovým kolesom 15 úplné odstráni a rovnako ako pravý, bude zaťažený aj tento 1’avý převod. Jedná sa o malé pohyby medzi hruškovým kolesom 13 a tanierovým kolesom 15 ktoré však stačia na to, aby sa pravý provod a to hlavně hruškové koleso 22 a taniorové koleso 20 předčasné opotřebovali, alebo úplné zničili, pretože ioh patřičné vydimonzovanio v malom priestore zbí jaoíoh valoov Ví,, 18, 21 na oolý motorový výkon nebolo možné. Zbí jaoio va.loe 14. 18, majú totiž dovolený Ion určitý maximálny priemer a tento nemožno zváčšovať podlá požiadavky len jodného kuželového převodu, ktorý by vyšiol dost’ velký, protože dnošné kombajny majú elektromotory pro pohon zbíjaoioho orgánu o výkone až 225 kW a zvačšoním priemoru zbíjaoioho orgánu by znemožnila vóboo činnost’ ooláho kombajnu, a naviao použitím Ion jodného tohoto převodu by sa medzi zbíjaoími valoami Ví, 21 vytvořil široký hluchý priestor, v ktorom by nemohli byť osadené nože, vznikali by tam nerozrušoné uholné rebrá, ktoré by značné znížili výkon kombajnu v uhlí.During operation, the electric motor 6 drives the gear wheel 4 by the shaft J, and the planet wheels J, 33 which roll along the gear shaft 6, thereby reducing rotation and driving the shaft 12 and the fixed disk 29 and the satellites 31. which engages the plate wheels 28, 32 fixedly coupled to the gears 26. 8, from where the torque is transmitted by the wheels 11, 27 by the shafts 12, 24, the pear wheels 13, 22 and the plate wheels 15, 20 to the epoch shaft 17. on which the eu is placed on a combine harvester. If the bevel gears are 13, 15 and 22, 20 with the same gear shaft, everything is fine and both are equally loaded. If, however, one gear has a different tooth clearance than the other, then the gear with a smaller gear pulls more or everything and the other less, or runs idle, the first gear being overloaded with all the engine power will be broken because of the tightness in It was not possible to design a small engine space for full engine power and therefore two gears had to be selected. In this case, however, the overloaded gear pauses, slows down, for example, it is right with the gear wheel 27. 8 and since the disk 29 is still pulled by the electric motor J and the shaft 2> the satellite J, 31 starts rolling over the plate wheel 32 of its rotation. are transferred to the plate wheel 28, rigidly connected to the wheel 26 and the wheel 11 by the shaft 12 to the pear wheel 13, which thereby gains a turn, actually only the motion transmitted by the satellites from the right gear, thereby making the gear between the pear wheel 13 and the plate wheel. 15 will completely remove and, like the right one, this left gear will also be loaded. These are small movements between the pear wheel 13 and the plate wheel 15, but are sufficient to ensure that the right gear, especially the pear wheel 22 and the tanior wheel 20 is prematurely worn or completely destroyed, since ioh due to the small-scale defeat of the yoke. He knows, 18, 21 for oolý engine power was not possible. They are allowed to have a certain maximum diameter, and this cannot be increased as required by the iodine bevel gear, which would be large enough, since the bottom harvesters have electric motors for driving up to 225 kW of power and up to a power of up to 225 kW. diameter of the killing organ would make it impossible for the boom to operate in an oily harvester, and by using iodine this transfer would create a wide deaf space between the knuckle walls, where the blades could not be fitted, creating undisturbed angle ribs that would greatly reduce power harvester in coal.
