Sve po\u010dinje sa \u017eljebom. Prije nego \u0161to popre\u010dni le\u017eajevi apsorbiraju promjene ugla, prije nego \u0161to se teleskopske cijevi prilagode udaljenosti, prva mehani\u010dka veza izme\u0111u va\u0161eg traktora i pogonskog sklopa kardanskog vratila doga\u0111a se na \u017eljebnom spoju. Ako se \u017eljeb pogrije\u0161i, ni\u0161ta drugo ne\u0107e biti va\u017eno. Klinasto vratilo kardana traktora za poljoprivredne ma\u0161ine<\/strong> je izgra\u0111en oko postizanja ispravnog su\u010delja, s precizno obra\u0111enim vilju\u0161kama s utorima koje odgovaraju 6-zglobnim, 21-zglobnim i metri\u010dkim 8-zglobnim priklju\u010dnim vratilima koja se koriste na traktorima koji se prodaju na korejskom tr\u017ei\u0161tu.\u00a0\u00a0\"Klinasto<\/p>\n

Za\u0161to je konfiguracija splinea toliko va\u017ena<\/h3>\n

The spline transmits all of the tractor’s PTO torque through interlocking teeth on the yoke bore and the PTO stub. A 6-spline interface has six teeth distributing the load, while a 21-utor<\/strong> interface spreads the same torque across twenty-one teeth, resulting in lower stress per tooth. This is why higher-HP, 1000-RPM PTO outputs typically use 21-spline connections. Choosing the Tractor PTO Spline Shaft with the correct tooth count and diameter ensures a tight fit that doesn’t wear, rattle, or slip during operation.<\/p>\n

Spline adapteri i opcije konfiguracije<\/h2>\n

Not every tractor-to-implement combination uses the same spline on both ends. That’s where adapters come in. The Tractor PTO Spline Shaft for Agricultural Machinery is available in several spline configurations to handle mismatched equipment:<\/p>\n

\"Adapteri<\/p>\n

Adapter sa 6 utora<\/h3>\n

Spaja 6-zubni priklju\u010dak kardanskog vratila na 6-zubni ulaz priklju\u010dka. Ovo je naj\u010de\u0161\u0107a konfiguracija za primjene od 540 o\/min na traktorima ispod 75 KS. Jaram adaptera je oblo\u017een cinkom radi otpornosti na koroziju i dizajniran je da izdr\u017ei vanjske udare tokom normalnog rada na polju.<\/p>\n

21-utorski adapter<\/h3>\n

Za izlaze PTO od 1000 o\/min. Finiji razmak zuba 21-utor<\/strong> Interfejs zahtijeva stro\u017ee proizvodne tolerancije, a na\u0161i CNC obra\u0111eni otvori za \u017eljebove ispunjavaju standarde ISO 500. \u017dljebno vratilo kardana traktora s 21-\u017eljebnim vilju\u0161kama obi\u010dno se uparuje s ure\u0111ajima ve\u0107e snage poput velikih rotacijskih reza\u010da, okruglih balirki i visokou\u010dinkovitih mije\u0161alica za hranu.<\/p>\n

Metri\u010dke opcije za 8-spline<\/h3>\n

Japanese-market tractors from Kubota, Yanmar, and Iseki often use metric spline dimensions (8-spline 38×32, 42×36, or 48×42 mm). We stock these alongside the standard inch configurations so Korean operators using Japanese compact tractors don’t need separate adapter bushings.<\/p>\n

Kako identificirati konfiguraciju splinea<\/h2>\n

If you’re not sure which klinasto vratilo<\/a> konfiguraciju koju va\u0161 traktor koristi, evo tri brze metode identifikacije:<\/p>\n

Metoda 1: Brojanje zuba<\/h3>\n

Look at the tractor PTO stub end-on and count the raised teeth. Six large teeth = 6-spline. Twenty-one fine teeth = 21-spline. This is the fastest way to identify the configuration and it doesn’t require any tools.<\/p>\n

Metod 2: Izmjerite pre\u010dnik<\/h3>\n

Use a caliper across the outer diameter of the PTO stub. Common readings: 34.9 mm (1-3\/8″) for both 6 and 21 spline, 44.5 mm (1-3\/4″) for heavy-duty 6 or 20 spline, or metric sizes like 38 mm for Japanese compact tractors.<\/p>\n

Metoda 3: Provjerite priru\u010dnik za traktor<\/h3>\n

The operator’s manual specifies the PTO spline type. If you’ve lost the manual, our Korean support team can look up the spline configuration by tractor make and model. Send us your tractor details and we’ll confirm the correct Tractor PTO Spline Shaft specification within one business day.<\/p>\n

Tro\u0161enje \u017eljebova: uzroci, znakovi i prevencija<\/h2>\n

Spline wear is the gradual loss of material on the interlocking teeth of the yoke bore and PTO stub. Once wear passes a critical point, the connection develops play that accelerates further damage and can lead to rounding off of the teeth entirely. Here’s what to watch for:<\/p>\n
