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

关键参数表

范围 规格 Why It Matters for Hay Rake
输入速度 540 rpm 影响齿轮节线速度和润滑状态
比率 1:1.5 reduction 将输入转速与所需的输出转速相匹配。
持续扭矩 85 Nm 判断变速箱能否承受连续运转
服务系数 1.25 Critical for hay rake shock loading conditions
房屋材料 die-cast aluminium sealed-for-life 影响强度和耐腐蚀性
大约重量 5.5 kg 影响安装要求和现场操作
轴配置 实心、空心、花键、键槽（可配置） 必须符合实现耦合规范

逐步选择工作流程

  1. 确认输入速度 — 确认您的拖拉机动力输出轴 (PTO) 转速是 540 转/分还是 1000 转/分（或前动力输出轴，如果适用）
  2. 计算所需输出 — the implement manufacturer typically specifies the output rpm and torque required at the hay rake drive shaft
  3. 应用正确的服务系数 — for hay rake duty we recommend at least 1.25 due to the loading characteristics described above
  4. 匹配轴配置 — 确认输入轴和输出轴的花键样式、键槽尺寸和轴长
  5. 指定安装方向 水平、垂直或倾斜安装方式会影响油位和密封件的选择。
  6. 定义环境密封 — 基于您运营中预计会遇到的粉尘、湿气和化学品暴露情况
  7. 验证润滑兼容性 — 确认推荐的机油等级符合您的保养程序

避免常见的选择错误

Why a 1.0 service factor will fail in Hay Rake duty
A service factor of 1.0 means the gearbox is rated only for steady, non-shock loading at constant load. Hay Rake 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.
需要球墨铸铁时选择铝
Aluminium housings save weight and cost but cannot absorb impact loading the way ductile iron can. For high-shock hay rake duty, ductile iron is the appropriate choice despite the weight penalty.
比例不匹配导致执行效率低下
使用接近但不完全符合农机规格的通用传动比，会导致农机输出速度超出其设计范围。这通常表现为作物产量下降、磨损加剧或振动增大。

Bevel vs Worm vs Helical: Which for Hay Rake?

类型 Best for Hay Rake? 优势 弱点
螺旋斜面 Most hay rake duty 90度功率传输，高效，坚固耐用 比直斜面更贵
蠕虫 高减速比保持载荷 自锁式，传动比极高，结构紧凑 效率低，产生热量
螺旋 直列轴应用 运行安静，动力输出平稳 无斜面阶段，无90度偏转

Installation, Lubrication & Maintenance for Hay Rake Gearboxes

Correct commissioning of a hay rake gearbox is the single biggest factor in long-term reliability. The following procedures are derived from field reports across single rotor rakes, twin rotor rakes and similar hay rake machinery operating in Australian conditions.

Commissioning Procedure for New Hay Rake Gearboxes

Pre-Run Alignment Check

Verify input shaft alignment within 0.10 mm at the gearbox mounting flange. Misalignment is the leading cause of dust ingress past lightweight seals in hay rake duty.

Oil Level on Cold Fill

Fill to the indicator while the gearbox sits at its operational mounting angle. Hay Rake 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 hay rake duty in dusty Australian paddocks, fit an inline filter at the breather to prevent dust ingress past lightweight seals.

Lubrication Strategy for Australian Climates

Australia covers extreme temperature ranges. Hay Rake gearboxes typically experience the following oil regimes:

Oil Specification Application Profile Recommended Australian Region
EP90 mineral GL-5 Light to moderate hay rake duty, ambient under 30 °C Tasmania, southern Victoria, cooler southern coastal districts
EP140 mineral GL-5 Continuous hay rake 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 Hay Rake Gearboxes

保养间隔 Required Action for Hay Rake 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 Hay Rake Duty

Oil leakage at input shaft seal during hay rake operation
In hay rake duty the most common root cause is breather contamination from the operating environment — dust ingress past lightweight seals. 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 single rotor rakes 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 hay rake loads.
Excessive housing temperature beyond 90 degrees Celsius
Often linked to tine arm shock loading on output. 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 twin rotor rakes 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 Hay Rake Equipment

Why the Right PTO Shaft Matters

For hay rake 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 single rotor rakes, twin rotor rakes and other hay rake 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 hay rake 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 hay rake drivelines.
