Spesifikasi Teknikal & Panduan Pemilihan

Sugarcane Harvester agricultural gearbox specifications

Spesifikasi Rujukan Kejuruteraan

The following parameters represent the typical specification range for sugarcane harvester gearboxes supplied to Australian customers. Custom configurations are available on request.

Jadual Parameter Utama

Parameter Spesifikasi Why It Matters for Sugarcane Harvester
Kelajuan input 540 rpm or 1000 rpm Mempengaruhi halaju garisan pitch gear dan rejim pelinciran
Nisbah 1:1.46 Memadankan kelajuan input dengan rpm output yang diperlukan
Tork berterusan 1,150 Nm Menentukan sama ada kotak gear boleh mengekalkan tugas berterusan
Faktor perkhidmatan 2.5 Critical for sugarcane harvester shock loading conditions
Bahan perumahan ductile iron heavy-section with cooling fins Mempengaruhi kekuatan dan rintangan kakisan
Berat anggaran 78 kg Mempengaruhi keperluan pemasangan dan pengendalian lapangan
Konfigurasi aci Padu, berongga, berpintal, berkunci (boleh dikonfigurasikan) Mesti sepadan dengan spesifikasi gandingan pelaksanaan

Alur Kerja Pemilihan Langkah demi Langkah

  1. Sahkan kelajuan input — sahkan sama ada PTO traktor anda berjalan pada 540 rpm atau 1000 rpm (atau PTO hadapan jika berkenaan)
  2. Kira output yang diperlukan — the implement manufacturer typically specifies the output rpm and torque required at the sugarcane harvester drive shaft
  3. Gunakan faktor servis yang betul — for sugarcane harvester duty we recommend at least 2.5 due to the loading characteristics described above
  4. Padankan konfigurasi aci — sahkan corak spline, dimensi utama dan panjang aci untuk kedua-dua input dan output
  5. Tentukan orientasi pemasangan — pemasangan mendatar, menegak atau bersudut mempengaruhi pemilihan paras minyak dan pengedap
  6. Takrifkan pengedap alam sekitar — berdasarkan pendedahan habuk, kelembapan dan bahan kimia yang dijangkakan dalam operasi anda
  7. Sahkan keserasian pelinciran — sahkan gred minyak yang disyorkan sepadan dengan rutin servis anda

Kesilapan Pemilihan Biasa yang Perlu Dielakkan

Why a 1.0 service factor will fail in Sugarcane Harvester duty
A service factor of 1.0 means the gearbox is rated only for steady, non-shock loading at constant load. Sugarcane Harvester applications routinely produce peak loads well above continuous duty due to the conditions described. Using a 1.0 service factor unit results in tooth pitting, bearing fatigue and premature failure within months rather than years.
Memilih aluminium apabila besi mulur diperlukan
Aluminium housings save weight and cost but cannot absorb impact loading the way ductile iron can. For high-shock sugarcane harvester duty, ductile iron is the appropriate choice despite the weight penalty.
Nisbah yang tidak sepadan menyebabkan prestasi pelaksanaan yang rendah
Menggunakan nisbah generik yang hampir dengan tetapi tidak sepadan dengan spesifikasi alat anda menghasilkan kelajuan output yang mengendalikan alat di luar sampul reka bentuknya. Ini sering muncul sebagai prestasi pemotongan yang lemah, haus yang dipercepat atau getaran.

Bevel vs Worm vs Helical: Which for Sugarcane Harvester?

Jenis Best for Sugarcane Harvester? Kekuatan Kelemahan
Serong lingkaran Most sugarcane harvester duty Pemindahan kuasa 90 darjah, kecekapan tinggi, teguh Lebih mahal daripada serong lurus
Cacing Beban pegangan pengurangan tinggi Mengunci sendiri, nisbah yang sangat tinggi, padat Kecekapan yang lebih rendah, menghasilkan haba
Heliks Aplikasi aci sebaris Operasi yang senyap, aliran kuasa yang lancar Tiada pesongan 90 darjah tanpa peringkat serong

Installation, Lubrication & Maintenance for Sugarcane Harvester Gearboxes

Correct commissioning of a sugarcane harvester gearbox is the single biggest factor in long-term reliability. The following procedures are derived from field reports across self-propelled chopper harvesters, whole-stick cane harvesters and similar sugarcane harvester machinery operating in Australian conditions.

Commissioning Procedure for New Sugarcane Harvester Gearboxes

Pre-Run Alignment Check

Verify input shaft alignment within 0.10 mm at the gearbox mounting flange. Misalignment is the leading cause of chopper cyclic loading on output bearings in sugarcane harvester duty.

Oil Level on Cold Fill

Fill to the indicator while the gearbox sits at its operational mounting angle. Sugarcane Harvester units running tilted or vertical require different fill volumes than horizontal mounted gearboxes.

Cover Bolt Torque Sequence

Tighten cover and seal-carrier bolts in a cross pattern to the torque specified on the shipping tag. Over-tightening distorts the seal carrier and causes immediate weeping.

Breather Vent Position

Mount the breather at the highest point. For sugarcane harvester duty in dusty Australian paddocks, fit an inline filter at the breather to prevent chopper cyclic loading on output bearings.

Lubrication Strategy for Australian Climates

Australia covers extreme temperature ranges. Sugarcane Harvester gearboxes typically experience the following oil regimes:

Oil Specification Application Profile Recommended Australian Region
EP90 mineral GL-5 Light to moderate sugarcane harvester duty, ambient under 30 °C Tasmania, southern Victoria, cooler southern coastal districts
EP140 mineral GL-5 Continuous sugarcane harvester duty over 4 hours, ambient 30-40 °C QLD inland, NSW Riverina, WA wheatbelt summer operations
Synthetic ISO VG 220 Heavy duty over 8 hours daily, sustained ambient over 40 °C NT, north QLD, hot inland summer harvest operations

Maintenance Schedule for Sugarcane Harvester Gearboxes

Selang Perkhidmatan Required Action for Sugarcane Harvester Duty
Daily / 8 operating hours Visual inspection for oil weep at input/output seals, listen for bearing noise during run-up, hand-check housing temperature after 30 minutes
Every 50 operating hours Check cold oil level, inspect breather and clean if dust build-up found, examine input shaft for fretting at coupling face
Every 250 operating hours Drain oil and inspect for metal particles or water contamination, refill with correct grade, replace breather, check input shaft axial play (max 0.15 mm)
End of season / annual Full disassembly inspection at workshop, replace all seals as preventive measure, gear backlash measurement (replace if over 0.20 mm), housing crack inspection, repaint exterior

Troubleshooting Specific to Sugarcane Harvester Duty

Oil leakage at input shaft seal during sugarcane harvester operation
In sugarcane harvester duty the most common root cause is breather contamination from the operating environment — chopper cyclic loading on output bearings. Clean or replace the breather first, then inspect the input shaft for surface fretting at the seal lip. Replace shaft and seal as a set if wear is detected.
Audible whine or grinding at full PTO speed
For self-propelled chopper harvesters this typically signals tooth pitting or insufficient lubricant film. Stop operation immediately, drain oil and inspect for metal particles. Continued running with this symptom causes catastrophic failure within 3 to 8 hours under typical sugarcane harvester loads.
Excessive housing temperature beyond 90 degrees Celsius
Often linked to juice contamination causing internal corrosion. Switch to a higher viscosity grade or synthetic ISO VG 220 if your duty cycle is above 6 hours continuous. Verify oil level is correct for the mounting orientation.
Unusual vibration through whole-stick cane harvesters frame
Check input shaft runout first using a dial indicator at 0.05 mm tolerance. If runout is in spec, inspect bearings — vibration that increases with PTO rpm typically indicates rotor imbalance, while vibration constant across all speeds indicates internal misalignment.

PTO Shaft Pairing for Sugarcane Harvester Equipment

Why the Right PTO Shaft Matters

For sugarcane harvester duty, the most common preventable downtime comes from PTO shaft failures rather than the gearbox itself. Specifying a matched shaft eliminates this risk. We supply complete drivelines for self-propelled chopper harvesters, whole-stick cane harvesters and other sugarcane harvester configurations.

Spline series

1-3/8″ 6-spline or 21-spline matched to tractor PTO

Length range

Telescoping tubes from 600 mm to 1,800 mm closed length

Torque protection

Friction clutch or shear bolt sized for sugarcane harvester loads

Safety compliance

AS/NZS 4024 compliant guarding for Australian use

Pairing your gearbox order with a matched PTO shaft eliminates the dimensional mismatch issues that cause spline fretting, premature universal joint failure and clutch slippage. Browse our complete PTO shaft range for sugarcane harvester drivelines.
