Opfindelsen angår en dr ivtransmission til høstmaskiner, og som omfatter et drivgear, der har en på en drivaksel drejeligt lejret dreven remskive og direkte eller over et valgfrit indkobleligt reduktionsgear indirekte virker på en drivaksel, 5 f.eks. drivakselen for en tærskecy1 inder, og hvor reduktionsgearet er udskifteligt med en medbringerklokke.BACKGROUND OF THE INVENTION The invention relates to a drive transmission for harvesting machines, which comprises a drive gear having a driven pulley mounted on a drive shaft and directly or via an optionally switchable reduction gear acting indirectly on a driving shaft, e.g. the drive shaft for a threshing cylinder, and the reduction gear being interchangeable with a carrier bell.
Fra tysk offentliggørelsesskrift nr. 23 54 440 kendes et til mejetærskere beregnet tærskecy!inderdrev, som har et stort 10 indsti 11 ingsområde for tærskecy1 inderens omdrejningstal. Hertil er tærskecy!inderdrevet udstyret med et planetgear, hvis hus på periferien har kileremprofi 1, og hvorover planetgearet kan drives. Såfremt planetgearet skal arbejde som reduktions-gear, bliver en tallerkenformet skive, der er fastgjort til en 15 tandhjulsbøsning, drejefast forbundet med tærskecylindervæggen ved hjælp af en skrue. På grund af den faste forbindelse mellem den tallerkenformede skive og tærskecylindervæggen, opstår der en styret afrulning af planethjulet på tandhjulsbøsningens solhjul. Såfremt der er behov for at tærskecylinderen skal 20 dreje i det høje omdrejningstalområde, forbindes gearhuset og den tallerkenformede skive med hinanden. Dette sker ved at skrue den nævnte skrue ind i en på den tallerkenformede skive fastgjort gevindbøsning. I dette tilfælde roterer planetgearets hus sammen med kileremskiven. Endvidere er det muligt at 25 udskifte planetgearet med en omsluttende drivskive. Da drivforbindelsen mellem akselen og remskiven sker ved hjælp af den i den tallerkenformede skive indførte skrue, tjener den omsluttende drivskive udelukkende til at afdække den fritliggende akseltap.From German Patent Publication No. 23 54 440 there is known a combine harvester designed for combine harvesters, which has a large 10 setting range for throttle cylinder rotational speed. For this purpose, the threshing cylinder is equipped with a planetary gear whose housing on the periphery has a V-belt profile 1 and over which the planetary gear can be driven. If the planetary gear is to act as a reduction gear, a disc-shaped disc attached to a gearbox is pivotally connected to the threshing cylinder wall by means of a screw. Due to the fixed connection between the plate-shaped disc and the threshing cylinder wall, a controlled unrolling of the planet wheel occurs on the gear wheel's sun gear. If there is a need for the threshing cylinder to rotate in the high speed range, the gear housing and the disc-shaped disc are interconnected. This is done by screwing said screw into a threaded sleeve attached to the plate-shaped disc. In this case, the planetary gearbox rotates with the V-belt pulley. Furthermore, it is possible to replace the planetary gear with an enclosing drive disc. Since the drive connection between the shaft and the pulley is made by means of the screw inserted into the plate-shaped disc, the enclosing drive disc serves solely to cover the exposed shaft pin.

Formålet med opfindelsen er med henblik på udvidelse af området for mulige omdrejningstal, at udforme drivtransmissionen således, at der efter fjernelse af reduktionsgearet uden større konstruktive ændringer kan tilvejebringes en enkelt driv-35 forbindelse mellem en indstillelig drivskive og den drevne aksel .The object of the invention is, in order to extend the range of possible rpm, to design the drive transmission so that, after removal of the reduction gear, without a single structural change, a single drive connection can be provided between an adjustable drive disc and the driven shaft.
Til opnåelse af dette formål er drivtransmissionen ifølge opfindelsen ejendommelig ved, at medbringerklokken enten kan 2To achieve this purpose, the drive transmission according to the invention is peculiar in that the carrier clock can either 2

forbindes drejefast med drivgearets indstillelige, drevne skive eller med drivakselen, og er udformet som tætningslegeme for en til remskiven hørende remspændeanordning, på hvilket legeme remskivens ene skivehalvdel tætnende ligger an. Herved 5 kan der mellem den drevne skive og drivakselen som drivforbindelse anbringes en medbringerklokke, som uden videre kan udskiftes med et reduktionsgear, idet reduktionsgearet i stedet for medbringerklokken kan integreres i den kraftoverførende forbindelse mellem den drevne skive og drivakselen. Den drevne 10 skive kan uden herpå at foretage ændringer til stadighed forblive på drivakselen. Med henblik på også at beskytte remspæn-deanordningen, når reduktionsgearet er fjernet, er medbringerklokken også udformet som et tætningslegeme, hvorpå den indstillelige del af remskiven tætnende ligger an.is pivotally connected to the adjustable, driven disc of the drive gear or to the drive shaft, and is formed as a sealing body for a belt clamping device, to which the one disc half of the pulley seals sealingly. Hereby, a driving bell can be arranged between the driven washer and the drive shaft as a driving connection, which can be replaced by a reduction gear, since the reduction gear can instead of the carrier clock be integrated into the power transfer connection between the driven washer and the drive shaft. The driven disk 10 can, without making any changes, remain on the drive shaft. In order to also protect the belt tensioning device when the reduction gear is removed, the carrier bell is also formed as a sealing body on which the adjustable part of the pulley seals.

Ifølge opfindelsen kan medbringerklokken med sin ene ende forbindes drejefast med remspændeanordning, som er drjeningsmo-nentafhængig for en skivehalvdel i den drevne skive, og med sin anden ende forbindes drejefast med en anden, aksialt fast-20 stående skivehalvdel.According to the invention, the carrier bell can be connected with one end to a pivot-fast with a belt tensioning device which is torque-dependent for a disc half of the driven disc, and at its other end can be pivotally connected to another, axially fixed disc half.
Endvidere kan ifølge opfindelsen reduktionsgearet være udfor met som et planetdrev, og dets solhjul eller planethjulsholder valgfrit forbindes drejefast med den drevne aksel ved hjælp af 25 en skydermuffe.Furthermore, according to the invention, the reduction gear can be designed as a planetary drive, and its sun wheel or planet wheel holder can optionally be pivotally connected to the driven shaft by means of a sliding sleeve.
For at lette montagen af medbringerklokken eller reduktionsgearet kan desuden ifølge opfindelsen fastgørelsesorganer være indrettet til henholdsvis at kunne forbinde medbringerklokken 30 med drivskiven, eller at kunne fastgøre reduktionsgearet til drivskiven.In addition, in order to facilitate the mounting of the carrier clock or the reduction gear, fastening means according to the invention may be arranged to be able to connect the carrier clock 30 with the drive disc, respectively, or to be able to attach the reduction gear to the drive disk.
Endelig kan ifølge opfindelsen planethjulsholderen ved sin ene ende have tilgangsåbninger til montage af fastgørelsesorganer-35 ne. Såfremt reduktionsgearet skal afmonteres, så kan fastgø relsesorganerne herved uden videre fjernes gennem tilgangsåb-ni ngerne.Finally, according to the invention, the planet wheel holder may at one end have access openings for mounting the fasteners. If the reduction gear is to be removed, the fastening means can hereby be removed without delay through the access openings.

Opfindelsen forklares nærmere i forbindelse med en udførelsesform for drivtransmissionen ifølge opfi ndel sen og under henvisning til tegningen, hvor 5 fig. 1 viser den drevne skive i et drivgear i drivtransmissionen, hvilken skive over en medbringerklokke er drivforbundet med den ene ende af en drevet aksel, og fig. 2 den drevne skive med påbygget reduktionsgear.The invention is further explained in connection with an embodiment of the drive transmission according to the invention and with reference to the drawing, in which FIG. 1 shows the driven disk in a drive gear in the drive transmission, which disk over a carrier bell is driven connected to one end of a driven shaft; and FIG. 2 shows the driven disc with a reduction gear.
10 På tegningen betegner henvisningstallet 2 en drevet skive i et kun delvis vist drivgear, som hører til en drivtransmission til drift af en på tegningen ikke vist tærskecylinder. Tærske-cylinderen kan være anbragt på en drivaksel 5, på hvilken også 15 den drevne skive 2 er anbragt. Den drevne skive 2 står over en drivrem 4 i drivforbindelse med en fra en forbrændingsmotor trukket drivskive, som dog ikke er vist på tegningen. Den drevne skive består af en første skivehalvdel 6 og en anden skivehalvdel 8. Den første skivehalvdel 6 har et på drivakse-20 len 5 anbragt nav 10, der er lejret på akselen 5 ved hjælp af rullelejer 12 og 14. Den anden skivehalvdel 8 har ligeledes et nav 16, som er anbragt aksialt forskydeligt på navet 10 mod virkningen af en fjeder 18. Fjederen 18 kan udgøre en del af en på tegningen ikke nærmere vist, drejningsmomentafhængig 25 remspændeanordning. Den anden skivehavldel 8 er forsynet med en radialflange 20, på hvilken der er fastgjort en medbringer-klokke 22. I radialflangens 20 endeplade findes flere gevindboringer 24, der kan optage gevindbolte 26, som kan indskrues i boringer 28 i medbringerklokken 22. Til fastgørelse af med-30 bringerklokken 22 på navet 10 tjener gevindskruer 30, som hertil er ført gennem tilsvarende boringer 32 i medbringerklokken 22 og er indskruet i gevindboringer 34 i navet 10. Medbringer-klokken 22 har en cylinderformet bøsning 36, som omgiver en akselende 39 på drivakselen 5, og som over sin på tegningen 35 viste venstre ende er lukket af en dækplade 40. Bøsningen 36 kan ved hjælp af en flerkileforbindelse eller en pasfjeder 42 være udrejeligt fastgjort på akselenden 38. Medbringerklokken 22 danner en drejeforbi ndel se mellem akselenden 38 på drivak- 4In the drawing, the reference numeral 2 denotes a driven disc in a drive gear only partially shown, which belongs to a drive transmission for operating a threshing cylinder not shown in the drawing. The threshing cylinder may be mounted on a drive shaft 5 on which also the driven disc 2 is mounted. The driven disc 2 faces a drive belt 4 in drive communication with a drive disc drawn from an internal combustion engine, which, however, is not shown in the drawing. The driven disc consists of a first disc half 6 and a second disc half 8. The first disc half 6 has a hub 10 arranged on the drive shaft 5, which is mounted on the shaft 5 by means of roller bearings 12 and 14. The second disc half 8 has also a hub 16 which is axially displaceable on the hub 10 against the action of a spring 18. The spring 18 may form part of a torque-dependent belt tensioning device not shown in the drawing. The second disc holder portion 8 is provided with a radial flange 20 to which is attached a carrier bell 22. In the end plate of the radial flange 20 there are several threaded bores 24 which can receive threaded bolts 26, which can be screwed into bores 28 in the carrier bell 22. the bearing bell 22 on the hub 10 serves threaded screws 30 which are guided thereto through corresponding bores 32 in the carrier bell 22 and are screwed into threaded bores 34 in the hub 10. The bearing bell 22 has a cylindrical sleeve 36 which surrounds a shaft end 39 on the drive shaft. 5, and which is closed above its left end in the drawing 35 by a cover plate 40. The sleeve 36 can be removably fastened to the shaft end 38 by means of a multi-wedge connection or a pass spring 42. The carrier clock 22 forms a pivot connection between the shaft end 38 of the drive shaft. - 4

selen 5 og den ene skivehalvdel 6. Dersom der i den drevne skive 2 findes en drejningsmomentafhængig remspændeanordning, så står den anden skivehalvdel 8 ligeledes i drivoverførende forbindelse med medbringerklokken 22. Den anden skivehalvdel 8 5 er hertil over fjederen 18 og gevindboltene 26 forbundet udrejeligt med medbringerklokken 22. Medbringerklokken 22 er imidlertid udformet således, at navet 16 delvis kan skydes ind i skivehalvdelen 8. Ved formindskelse af den drevne skives· -2 virksomme diameter skydes fjederen 18 ind i medbringerklokken 10 22 og sammenpresses herved.harness 5 and one disc half 6. If there is a torque-dependent belt tensioning device in the driven disc 2, then the second disc half 8 is also in drive-transmitting connection with the carrier clock 22. The second disc half 8 5 is connected thereto via the spring 18 and the threaded bolts 26 However, the carrier clock 22 is formed such that the hub 16 can be partially pushed into the disc half 8. By reducing the effective diameter of the driven disc · -2, the spring 18 is pushed into the carrier clock 10 22 and is thereby compressed.
Medbringerklokken 22 er forsynet med en anden bøsning 43 med større diameter, som rager ind i den anden skivehalvdel 8, idet den delvis omgiver fjederen 18 og navet 16. Denne anden 15 bøsning 43 har ved en udvendig omkreds en tætningsflade 44, mod hvilken en radial tætningsring 46 ligger an og danner tætning udad for et af navet 16 dannet indvendigt rum 48. Hvis den anden skivehalvdel 8 på drivakslen 5, henholdsvis på navet 10 forskydes udad, så vil radialtætningsringen 46 på tætnings-20 fladen 44 også derved bevæges udad, således at den stadig danner tætning for det indvendige rum 48. Drivakselen 5 er drejeligt lejret i et kugleleje 50, som er anbragt i en sidevæg 52 i mejetærskerens stel, der ikke er vist nærmere på tegningen.The carrier bell 22 is provided with another larger diameter bushing 43 which projects into the second disc half 8, partially surrounding the spring 18 and the hub 16. This second bushing 43 has an outer circumference of a sealing surface 44 against which a radial sealing ring 46 abuts and seals outwardly for an interior space 48 formed by hub 16. If the second disc half 8 of drive shaft 5 and hub 10, respectively, is displaced outwardly, then radial sealing ring 46 on sealing surface 44 will also move outwardly, thus it still forms a seal for the interior space 48. The drive shaft 5 is pivotally mounted in a ball bearing 50 disposed in a side wall 52 of the combine harvester frame, not shown in detail in the drawing.
Et. andet på tegningen ikke vist kugleleje findes i den overfor 25 liggende sidevæg af stellet. Mellem ydersiden af sidevæggen 52 og den indad vendende sidevæg på den første skivehalvdel 6 findes på drivakselen 5 et trækkende kædehjul 56, som kan være i drivoverførende forbindelse med en mekanisme, der skal trækkes.One. other ball bearing not shown in the drawing is found in the opposite side wall of the frame. Between the outside of the sidewall 52 and the inward-facing sidewall of the first disc half 6, there is on the drive shaft 5 a pulling sprocket 56 which may be in drive transmitting connection with a mechanism to be pulled.

Det trinløst indstillelige drivgear er variabelt inden for et bestemt omdrejningstalsområde, således at tærskecylinderen kan drives med forskellige omdrejningstal. Ved visse kornsorter må tærskecylinderen løbe med meget små omdrejningstal. Da drivge-35 aret på grund af omsætningsforholdet ikke gør det muligt at foretage justering til sådanne omdrejningstal, bliver drivgearet tilkoblet et yderligere reduktionsgear. Et sådant reduktionsgear kan uden større ombygning indbygges senere i tærske- 5The infinitely adjustable drive gear is variable within a specific speed range so that the throttle cylinder can be operated at different speeds. For certain cereals, the threshing cylinder must run at very low rpm. Since the drive gear due to the turnover ratio does not allow for adjustments to such rpm, the drive gear is coupled to a further reduction gear. Such a reduction gear can be incorporated later in the threshing unit without major conversion

cylinderens drivtransmission. Hertil behøver man blot at fjerne medbringerklokken 22 efter at have løsnet gevindskruerne 30. Når medbringerklokken 22 aftages, frigives akselenden 38, på hvilken et med henvisningstallet 60 betegnet reduktionsgear 5 (fig. 2) kan påsættes. Redutkionsgearet 60 tilvejebringer drivforbindelsen mellem den drevne skive 2 og akselenden 38 på drivakselen 5. Reduktionsgearet 60 består af et gearhus 62, som er forsynet med et tragtformet husdæksel 64 og et andet, affladet dæksel 68, der har en boring 66. Dækslet 68 er ved 10 hjælp af et antal skruebolte 70 fast forbundet med husdækslet 64. Inden i gearhuset 62 findes en planetgearholder 72, som over en skydermuffe 74 er udrejeligt forbundet med akselenden 38. PIanetgearholderen 72 har en cylindrisk ansats 76, hvorpå der er anbragt et kugleleje 78, således at planethjulsholderen 15 72 er drejeligt lejret inden i gearhuset 62. Ved omkredsen af planethjulsholderen 72 findes flere planethjul 80, af hvilke dog kun ét er vist. Planethjulet 80 er ved hjælp af et rulle-leje 82 anbragt drejeligt i planethjulsholderen. Planethjulet 80 er i drivforbindelse med en med gearhuset 62 fast forbundet 20 indvendig tandkrans 84 og et med skivehalvdelen 8 fast forbundet solhjul 86. Solhjulet 86 har en indvendig fortanding 88, som griber ind i en udvendig fortanding 90 på skydermuffen 74. På denne måde fremkaldes en drejningsoverførende forbindelse mellem akselenden 38 og solhjulet 86. I den i fig. 2 vi-25 ste stilling af skydermuffen 74 sker drivtransmissionen direkte over drivskiven 2 og solhjulet 86 til drivakselen 5. Det med drivgearet indstillede omdrejningstal kan således ikke formindskes yderligere, da reduktionsgearet 60 ikke kommer i anvendelse.cylinder drive transmission. For this, one need only remove the driver clock 22 after loosening the threaded screws 30. When the driver clock 22 is removed, the shaft end 38 is released to which a reduction gear 5 (fig. 60) (fig. 2) can be mounted. The reduction gear 60 provides the drive connection between the driven disc 2 and the shaft end 38 of the drive shaft 5. The reduction gear 60 consists of a gear housing 62 which is provided with a funnel-shaped housing cover 64 and a second flared cover 68 having a bore 66. The cover 68 is at 10 by means of a plurality of screw bolts 70 firmly connected to the housing cover 64. Inside the gear housing 62 is a planetary gear holder 72 which is removably connected via a sliding sleeve 74 to the shaft end 38. so that the planet wheel holder 15 72 is rotatably mounted within the gear housing 62. At the circumference of the planet wheel holder 72 there are several planet wheels 80, of which only one is shown. The planet wheel 80 is pivotally mounted in the planet holder by means of a roller bearing 82. The planet gear 80 is in drive communication with an internal gear ring 84 connected to the gear housing 62 and a sun gear 86 connected to the disc half 8. The sun gear 86 has an internal tooth 88 which engages an external tooth 90 on the slider 74. a pivot transmitting connection between the shaft end 38 and the sun gear 86. In the embodiment of FIG. In the second position of the sliding sleeve 74, the drive transmission takes place directly over the drive disc 2 and the sun gear 86 to the drive shaft 5. Thus, the speed set with the drive gear cannot be reduced further, since the reduction gear 60 does not apply.

Hvis omdrejningstalsområdet imidlertid skal forøges, og tær-skecylinderen drives med et endnu lavere omdrejningstal, så må skydermuffen 74 over en på tegningen ikke vist indsti11ingsme-kanisme forskydes til venstre i figuren, således at den udven-35 dige fortanding 90 på skydermuffen 74 bringes i indgreb med en indvendig fortanding 92 på planethjulsholderen 72. Ved denne stilling af skydermuffen 74 foregår drivtransmissionen over drivskiven 2 og reduktionsgearet 60 til den drevne aksel 5.However, if the rpm range is to be increased and the throttle cylinder is driven at an even lower rpm, then the slider 74 over a positioning mechanism not shown in the drawing must be displaced to the left of the figure so that the external tooth 90 of the slider 74 is brought into position. engagement with an internal tooth 92 on the planet wheel holder 72. At this position of the slider 74 the drive transmission takes place over the drive disc 2 and the reduction gear 60 of the driven shaft 5.
