Pregled proizvoda<\/h2>\n

If you’ve been told your implement requires a lemon-profile driveline but aren’t sure which model fits, start here. The L Serija kardanskog vratila Limunska cijev<\/strong> Porodica proizvoda obuhvata sedam razli\u010ditih modela, od L1 do L6, plus specijalni L32. Svaki model koristi isti popre\u010dni presjek cijevi s dva rebra u obliku limuna, ali se pove\u0107ava u pre\u010dniku cijevi, veli\u010dini popre\u010dnog le\u017eaja i kapacitetu obrtnog momenta kako bi odgovarao razli\u010ditim klasama KS. Zajedno mogu da podnesu sve, od kompaktnog traktora od 10 KS koji pokre\u0107e sija\u010dicu do ma\u0161ine srednje klase od 80 KS koja pokre\u0107e kosilicu s diskovima.<\/p>\n

Limun profil je drugi najpopularniji oblik cijevi u korejskoj poljoprivredi, odmah nakon trouglastog. Korejski operateri obi\u010dno biraju L seriju kardanskog vratila u obliku limun cijevi kada priklju\u010dku treba umjerena kutna fleksibilnost na teleskopskom zglobu, posebno kod diskosnih kosilica, rotacijskih grablji i rasipa\u010da gnojiva gdje se visina priklju\u010dka \u010desto mijenja tokom rada.<\/p>\n

\"Kardansko<\/div>\n

Po \u010demu se L32 razlikuje od L1-L6?<\/h3>\n

The L32 is a specialty variant with a wider lemon tube profile designed for applications that need more overlap travel in a shorter overall length. It’s popular on front-mounted PTO implements and compact equipment where the distance between tractor and implement is limited. The standard L1 to L6 models follow the industry incremental sizing used across the industry.<\/p>\n

Ocjene obrtnog momenta po modelu<\/h2>\n

Select your L Series PTO Shaft Lemon Tube model based on these torque values. Always choose a model rated at least 25% above your tractor’s actual PTO torque output.<\/p>\n

Every L Series PTO Shaft Lemon Tube ships as a complete assembly, but understanding the individual components helps with maintenance and ordering replacement parts. Here’s what’s inside:<\/p>\n

Par limunskih tuba (unutra\u0161nji + vanjski)<\/h3>\n

Hladno vu\u010deni uglji\u010dni \u010delik C45 s karakteristi\u010dnim dvostrani\u010dnim profilom. Unutra\u0161nja cijev klizi unutar vanjske cijevi, prenose\u0107i obrtni moment kroz kontakt s povr\u0161inom, a istovremeno omogu\u0107ava aksijalno istezanje i kompresiju. Oblik limuna stvara blago djelovanje klina koje ravnomjernije raspore\u0111uje napon nego profili s o\u0161trim uglovima. Debljina stijenke kre\u0107e se od 3 mm na L1 do 4,5 mm na L6.<\/p>\n

Kovani jarmovi<\/h3>\n

Dva jarma od legiranog \u010delika 40Cr, jedan za kraj traktora i jedan za kraj priklju\u010dka. Svaki jaram ima u\u017eljebljeni otvor koji se spaja sa krajem kardana ili ulaznim vratilom mjenja\u010da. Limun cijev kardanskog vratila L serije podr\u017eava vi\u0161e stilova pri\u010dvr\u0161\u0107ivanja jarma: potisni klin (naj\u010de\u0161\u0107i), vij\u010dani klin, rascjepka, brzo otpu\u0161tanje, kuglasti priklju\u010dak i tip ovratnika. Sufiks broja dijela identificira koja je kombinacija jarma ugra\u0111ena.<\/p>\n

Kompleti s popre\u010dnim le\u017eajevima<\/h3>\n

Two universal joint assemblies, one at each end. Each kit contains four needle-roller bearing cups pre-loaded with EP grease and sealed with multi-lip dust seals. The cross-kit size scales with the L-series model number. L1 uses the smallest cross (22×54 mm), while L6 uses the largest in the range. Replacement kits are stocked individually for all models.<\/p>\n

Kako skratiti ili podesiti du\u017einu osovine<\/h2>\n

\u010cesto pitanje korejskih kupaca je da li se cijev za kardansko vratilo L serije mo\u017ee skratiti ako je standardna du\u017eina preduga\u010dka za njihovu konfiguraciju. Odgovor je da, ali postoje va\u017ena pravila kojih se treba pridr\u017eavati.<\/p>\n

Kada je skra\u0107ivanje neophodno<\/h3>\n

Ako Kardansko vratilo<\/strong> Ako se cijev potpuno spusti (unutra\u0161nja cijev skroz ulazi u vanjsku cijev) kada se alat podigne na transportnu visinu, osovina je preduga\u010dka. To uzrokuje blokiranje teleskopskog zgloba, \u0161to stvara prekomjerno aksijalno optere\u0107enje na popre\u010dne le\u017eajeve i mo\u017ee uzrokovati pucanje vilju\u0161ki. Skra\u0107ivanje je rje\u0161enje.<\/p>\n

Ispravan postupak rezanja<\/h3>\n

Both inner and outer lemon tubes must be cut by the same amount to maintain proper overlap. Mark the cut lines, then use a bandsaw or abrasive cutoff wheel (not a torch, which would distort the lemon profile and ruin the fit). After cutting, deburr the cut ends with a file. Ensure at least 150 mm of overlap remains at maximum extension. If you’re not confident about cutting, we offer Osovine L-serije prilago\u0111ene du\u017eine<\/a> izrezano po va\u0161oj specifikaciji u fabrici.<\/p>\n

Kako funkcioni\u0161e kardansko vratilo traktora<\/h2>\n

For operators new to PTO equipment, here’s a quick explanation of the mechanical principle. The tractor engine produces rotational power. A portion of that power is diverted through the PTO gearbox to a splined stub shaft protruding from the rear of the tractor. The L Series PTO Shaft Lemon Tube connects to that stub via the tractor-end yoke spline, transmits the rotation through the lemon tubes, and delivers it to the implement’s input shaft<\/a> putem vilju\u0161ke na kraju priklju\u010dka. Dva univerzalna zgloba omogu\u0107avaju osovini da radi pod blagim uglovima dok se priklju\u010dak pomi\u010de gore i dolje. Teleskopske cijevi u obliku limuna prilago\u0111avaju se promjenama udaljenosti dok se priklju\u010dak podi\u017ee, spu\u0161ta ili okre\u0107e.<\/p>\n

Spajanje osovine i mjenja\u010da L-serije<\/h3>\n

Kraj priklju\u010dne cijevi kardanskog vratila L serije na strani priklju\u010dka uvodi se u poljoprivredni mjenja\u010d<\/a> that converts PTO rotation to the speed and axis the working mechanism requires. A disc mower gearbox, for example, takes 540 RPM and redirects it to spin the cutting discs at the required blade tip speed. Make sure the gearbox input spline matches the shaft’s implement-end yoke. Specify both configurations when ordering.<\/p>\n

    \u010cesto postavljana pitanja<\/h2>\n

    Koji model L-serije odgovara traktoru od 40 KS sa diskosnom kosilicom?<\/strong><\/p>\n

    Za 40 KS pri 540 obrtaja u minuti, kontinuirani obrtni moment je oko 530 Nm. L3 (MP 640 Nm) pru\u017ea razumnu marginu. Ako kosilica \u010desto udara u gustu travu ili se zapetlja, pove\u0107ajte na L4 (MP 780 Nm) za dodatni prostor nad glavom.<\/p>\n

    What’s the difference between L2 and L32 if they have the same torque rating?<\/strong><\/p>\n

    Same torque capacity but different tube geometry. L32 has a wider lemon profile that gives more telescoping travel in a shorter closed length. It’s designed for tight mounting situations like front PTO implements. L2 uses the standard lemon profile with longer tube overlap.<\/p>\n

    Mogu li zamijeniti limunske cijevi trokutastim cijevima na istim dr\u017ea\u010dima?<\/strong><\/p>\n

    No. The yoke tube seat is shaped to match the tube profile. A lemon yoke won’t properly grip a triangular tube and vice versa. If you want to change profiles, you need a complete shaft assembly or new yokes with matching tube seats.<\/p>\n

    Koliko dugo traju cijevi od limuna L serije prije nego \u0161to ih je potrebno zamijeniti?<\/strong><\/p>\n

    Typically three to five seasons with proper lubrication (re-grease the overlap zone every 50 hours). If the tubes develop visible wobble or don’t slide smoothly, they’ve worn past the service limit and should be replaced as a pair.<\/p>\n

    Da li limunska cijev kardanskog vratila L serije odgovara japanskim kompaktnim traktorima?<\/strong><\/p>\n

    Da. Metri\u010dke vilju\u0161ke s 8 \u017eljebova za Kubota, Yanmar i Iseki dostupne su na svim modelima L-serije. Prilikom naru\u010divanja navedite marku i model traktora.<\/p>\n

    Mogu li dodati \u0161irokokutni zglob na limunsku cijev kardanskog vratila L serije?<\/strong><\/p>\n

    Da. Opcije zglobova WA (\u0161irokokutni) i CV (konstantna brzina) kompatibilne su sa svim modelima L-serije. Ku\u0107i\u0161te \u0161irokokutnog zgloba zamjenjuje standardni popre\u010dni le\u017eaj na kraju priklju\u010dka, pove\u0107avaju\u0107i maksimalni radni ugao sa 25 stepeni na 80 stepeni.<\/p>\n

    “L4 lemon shaft on a 50 HP tractor with a Krone-style disc mower. The lemon tubes handle the constant height changes as the mower follows the ground contour. Smooth telescoping, no binding. Ten months of regular mowing and the cross-bearings are still tight.”<\/p>\n

    \n

    Woo Seung-jun, trgovac poljoprivrednom opremom, Naju (krajem 2024.)<\/span><\/p>\n

    “I sell the L-series alongside the T-series. For customers running disc mowers or rotary rakes, I push the L-series because the lemon profile gives a smoother feel at the telescoping joint. L3 and L4 are my biggest movers. Consistent quality across all units I’ve stocked.”<\/p>\n

    \n

    Shin Hye-rin, vlasnik Kubote, Gyeonggi-do (po\u010detak 2025.)<\/span><\/p>\n

    “My Kubota B2650 came with a lemon-profile shaft from the factory. When it wore out, I replaced it with the L2 from Ever-Power. Exact dimensional match. The metric 8-spline yoke slid on with no play. Saves me the hassle of ordering from the Kubota dealer.”<\/p>\n

    \n

    Jeong Tae-hyun, Sto\u010darska farma, Jeju-do (sredina 2024.)<\/span><\/p>\n

    “L5 with SFF friction clutch for a round baler. The slip clutch has saved the baler gearbox at least three times when wet grass packed the chamber too tight. The L-series lemon tubes are holding up well even with the heavy baling work. Good investment.”<\/p>\n

    \n

    Han Do-yeon, Popravka poljoprivrednih ma\u0161ina, Suwon (jesen 2024.)<\/span><\/p>\n

    “I’ve shortened a few L-series shafts for customers with tight setups. The lemon tube cuts cleanly with a bandsaw and the profile remains true as long as you clamp it properly. Much easier than trying to cut star tubes. Individual replacement parts are available which makes my repair work straightforward.”<\/p>\n
