Gambaran Umum Produk<\/h2>\n

Spline adalah titik awal segalanya. Sebelum bantalan silang menyerap perubahan sudut, sebelum tabung teleskopik menyesuaikan jarak, sambungan mekanis pertama antara traktor dan poros penggerak PTO terjadi pada antarmuka spline. Jika spline salah, maka hal lainnya tidak akan berarti apa-apa. Poros Spline PTO Traktor untuk Mesin Pertanian<\/strong> Dirancang untuk memastikan antarmuka yang tepat, dengan dudukan spline yang diproses secara presisi agar sesuai dengan poros PTO 6-spline, 21-spline, dan metrik 8-spline yang digunakan pada traktor yang dijual di seluruh pasar Korea.\u00a0\u00a0\"Poros<\/p>\n

Mengapa Konfigurasi Spline Sangat Penting?<\/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

Adaptor Spline dan Opsi Konfigurasi<\/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

\"Adaptor<\/p>\n

Adaptor 6-Spline<\/h3>\n

Menghubungkan poros PTO 6-spline ke input implement 6-spline. Ini adalah konfigurasi paling umum untuk aplikasi 540 RPM pada traktor di bawah 75 HP. Dudukan adaptor dilapisi seng untuk ketahanan terhadap korosi dan dirancang untuk menahan benturan eksternal selama operasi lapangan normal.<\/p>\n

Adaptor 21-Spline<\/h3>\n

Untuk output PTO 1000 RPM. Jarak antar gigi yang lebih halus pada 21-spline<\/strong> Antarmuka ini membutuhkan toleransi manufaktur yang lebih ketat, dan lubang spline yang dikerjakan dengan mesin CNC kami memenuhi standar ISO 500. Poros Spline PTO Traktor dengan 21-spline biasanya dipasangkan dengan alat-alat berdaya kuda tinggi seperti pemotong putar besar, mesin pengepak jerami bundar, dan mixer pakan berkapasitas tinggi.<\/p>\n

Opsi Metrik 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

Cara Mengidentifikasi Konfigurasi Spline Anda<\/h2>\n

If you’re not sure which poros spline<\/a> Berdasarkan konfigurasi yang digunakan traktor Anda, berikut tiga metode identifikasi cepat:<\/p>\n

Metode 1: Menghitung Gigi<\/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: Mengukur Diameter<\/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: Periksa Buku Panduan 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

Keausan Spline: Penyebab, Tanda, dan Pencegahan<\/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
