Produktoversigt<\/h2>\n

Det er ved noten, at alting starter. F\u00f8r tv\u00e6rlejerne absorberer vinkel\u00e6ndringer, f\u00f8r teleskopr\u00f8rene justerer afstanden, sker den allerf\u00f8rste mekaniske forbindelse mellem din traktor og PTO-drivlinjen ved notforbindelsen. Hvis noten bliver forkert, betyder intet andet noget. Traktor PTO Spline Shaft til landbrugsmaskiner<\/strong> er bygget op omkring at f\u00e5 den rigtige gr\u00e6nseflade, med pr\u00e6cisionsbearbejdede splinegafler, der passer til 6-spline, 21-spline og metriske 8-spline PTO-studse, der bruges p\u00e5 traktorer, der s\u00e6lges p\u00e5 tv\u00e6rs af det koreanske marked.\u00a0\u00a0\"Traktor<\/p>\n

Hvorfor Spline-konfiguration er s\u00e5 vigtig<\/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-spline<\/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-adaptere og konfigurationsmuligheder<\/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

\"Traktor<\/p>\n

6-nots adapter<\/h3>\n

Forbinder en 6-spline PTO-studs til en 6-spline redskabsindgang. Dette er den mest almindelige konfiguration til 540 o\/min applikationer p\u00e5 traktorer under 75 hk. Adaptergaflen er zinkbelagt for korrosionsbestandighed og designet til at modst\u00e5 eksterne p\u00e5virkninger under normal markdrift.<\/p>\n

21-Spline-adapter<\/h3>\n

For PTO-ydelser p\u00e5 1000 o\/min. Den finere tandafstand p\u00e5 21-spline<\/strong> Gr\u00e6nsefladen kr\u00e6ver strammere produktionstolerancer, og vores CNC-bearbejdede notboringer overholder ISO 500-standarderne. Traktorens PTO-notaksel med 21-nots gaffelgafler parres typisk med redskaber med h\u00f8jere HK som store rotorsk\u00e6rere, rundballepressere og h\u00f8jtydende foderblandere.<\/p>\n

Metriske 8-spline-muligheder<\/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

S\u00e5dan identificerer du din spline-konfiguration<\/h2>\n

If you’re not sure which spline-aksel<\/a> konfiguration, som din traktor bruger, er her tre hurtige identifikationsmetoder:<\/p>\n

Metode 1: T\u00e6l t\u00e6nderne<\/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

Metode 2: M\u00e5l diameteren<\/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

Metode 3: Tjek traktorens manual<\/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

Splineslid: \u00c5rsager, tegn og forebyggelse<\/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
