Engineering Features of the Grain Handling Gearbox

Each of the cards below describes a specific, measurable attribute of the GH Series unit. Generic claims have been kept out — every number here is tied to a manufacturing process or a verified test result.

宽广的操作窗口
使用合成GL-5润滑油，在-25℃至+85℃的温度范围内进行了测试。该装置在寒冷的早晨能够顺利启动，并且在烈日炙烤的夏季田野中也能保持良好的密封性能。
防腐蚀涂层
Outer surfaces receive a zinc-phosphate base then a baked epoxy topcoat to 80 µm thickness. Salt-spray resistance ≥ 480 hours, important for high-cycle duty.
现场可修复设计
螺栓固定的端盖和标准化的密封尺寸意味着磨损的轴封或输出轴承可以在农场使用手动工具进行更换——无需返厂维修。
法兰兼容性
备有多种螺栓孔距规格：100 × 100 毫米方形、BCD 130 毫米圆形和 ISO 9409-A 标准。更换到现有农具上通常无需适配器。
⏱️ 已进行磨合测试
每个组装好的变速箱在包装前都会在空载试验台上运行至少 30 分钟，以确认轴承预紧力、油位保持和声学特征。
澳大利亚气候适应能力
选定的密封件和润滑油规格可抵抗紫外线引起的脆化以及昆士兰州和新南威尔士州大面积作业条件下典型的多尘作业环境。
检查记录
每批货物都附带一份内部检验表，记录齿轮齿接触模式、齿隙、轴承扭矩和磨合噪声读数——每个单元完全可追溯。
⚙️ 硬化齿轮组
Gear teeth are forged from 20CrMnTi alloy steel, then carburized and oil-quenched to a surface hardness of HRC 58–62 with a tough HRC 33–45 core. Load capacity is more than double that of basic 45# steel gears.

How to Select the Right Grain Handling Gearbox

Use the three-step approach below to match a GH Series-class unit to your tractor and implement.

  1. 措施 — 记录您的拖拉机动力输出轴标准（540 / 1000 RPM，花键数）、农具输入轴直径和长度，以及农具前端的可用螺栓孔距。
  2. 匹配 — cross-check those measurements against the spec table for the GH Series. The flange, shaft, and ratio need to all line up before moving on.
  3. 负载下验证 — 确认额定输入功率和输出扭矩是否足以满足您的峰值运行条件（例如潮湿土壤、茂密作物、冷启动）。

遴选标准清单

选择标准 决策点
实现类型→比率匹配 For grain handling / combine harvester, target gear ratio in the 1:1 – 1:3 range for correct rotor or output speed.
拖拉机动力带 Match input power rating to your tractor: 60–250 HP is the practical envelope for the GH Series family.
动力输出轴转速（540 转/分 vs 1000 转/分） 100马力以下的拖拉机标准转速为540转/分；100马力以上的拖拉机以及需要更高输出速度的场合，建议使用1000转/分的动力输出轴。指定动力输出轴转速前，请务必确认拖拉机的动力输出轴输出功率。
房屋材料 铸铁（HT250 / QT500）适用于重型连续作业；铝合金适用于需要减轻重量和快速散热的场合，例如经常移动的小型工具。
布局 直角（90°）装置将动力输出轴的动力传递至垂直的工作轴；直列式装置则保持轴的对准。选择时应根据农具的几何形状而定。
标准版与定制版 标准型号涵盖了大部分原厂配套 (OEM) 位置。对于非标准传动比、特殊轴端、超大法兰或严苛环境规格，请联系我们进行定制生产。
轴端接口 验证输入 PTO 标准（6 齿花键、21 齿花键、20 齿花键）和输出端（键槽式、花键式、法兰式）是否与您的传动系统和农具相符。
工作环境 高粉尘、泥浆、盐雾或极寒环境可能需要 IP66 防护等级的密封件、低温合成油或防腐蚀涂层——请在报价时注明。

典型应用及动力传输任务

The GH Series is engineered for grain handling / combine harvester. The scenarios below describe the specific power-transmission tasks the gearbox is designed to handle, with details of mounting position, drive path, and the technical demand on the gear and bearing set.

Grain Auger Drive

Drives the in-bin or portable auger that moves grain. Long runs at moderate torque make oil retention and lifetime sealing essential.

Grain Unloading System

Drives the unloading auger from a combine grain tank to a chase truck. Fast unload cycles place peak torque demands during start-up.

Grain Transport Conveyor

Drives belt or chain conveyors in grain handling facilities. Continuous duty over long shifts.

Combine Harvester Reverser

Allows the operator to reverse the threshing/feeding system to clear jams. Brief high-torque-reversal duty cycles place high demand on bearing rigidity.

安装调试指南

Correct installation of the grain handling gearbox is the single biggest factor in achieving the design service life. Follow the steps below, in order. Skipping or compressing any step usually shows up as oil leak, premature bearing failure, or noise within the first season.

  1. 安全准备。 关闭拖拉机发动机，拔出钥匙，断开动力输出轴（PTO），拉起驻车制动器，并用楔块固定车轮。佩戴安全手套和护目镜。在进行任何传动系统作业之前，务必确认农具已放置在稳定的支撑物上。
  2. 安装前请检查变速箱。 Check that the GH Series model number, input flange dimensions, and input/output shaft specifications match both your tractor PTO and the implement input shaft. Mismatched flange or spline patterns will not be corrected by force-fitting.
  3. 加入润滑剂。 Before first use, fill with the specified lubricant — typically SAE 90 GL-4 — to the centre of the oil-level window. Refer to the spec table for the exact oil capacity for your unit; underfilling causes early bearing wear, overfilling raises oil temperature and stresses seals.
  4. 安装并拧紧螺栓。 Bolt the gearbox flange to the implement using the OEM bolt set. Tighten in a diagonal pattern in three passes to the final torque (~ 110 N·m for M14 grade 8.8). Even loading prevents flange distortion and seal leak paths.
  5. 连接输入动力输出轴。 将动力输出轴驱动轴轭连接到变速箱输入轴上。确认锁定销或推拉环完全啮合。重新安装安全护罩，确保两条固定链分别连接到拖拉机和农具上，并且护罩不会随轴一起旋转。
  6. 连接输出轴。 将输出轴滑入农具工作轴，对准键或花键，并用提供的锁紧螺母和垫圈锁紧。确认轴的轴向间隙在制造商规定的公差范围内——通常为 0.05 毫米至 0.20 毫米。
  7. 检查轴的对准情况。 变速箱螺栓固定好，轴也连接好后，用手缓慢旋转。输入轴和输出轴的总跳动量（TIR）不应超过 0.10 毫米。任何卡顿或明显的刮擦声都表明存在对准问题，必须在通电运行前进行纠正。
  8. 空载测试运行。 将动力输出轴（PTO）在低发动机转速（怠速至 540 转/分）下运转 5 至 10 分钟。注意是否有异常噪音，观察是否有漏油，并用手检查壳体温度——摸起来应该是温热的，但不能烫手。
  9. 部分负载下的运行。 前50小时运行期间，避免满负荷运转。应逐步改变转速并轻柔地施加负载，以使齿轮和轴承充分磨合。磨合期结束后，排出润滑油（其中含有微小的磨合颗粒），并重新加注相同等级的新油。
  10. 制定维护计划。 每运行 200 小时检查一次油位，或在重负荷使用期间每周检查一次。每运行 500 小时或每个季度更换一次齿轮油，以先到者为准。每次换班后擦拭壳体外部，以防止污垢积聚并导致水分滞留在密封件上。
⚠️ 安全警告。 请勿超过额定输入转速。切勿空转——即使短暂无油运转也会损坏齿轮和轴承。切勿在动力输出轴 (PTO) 接合时维修或检查变速箱。恢复运转前，务必重新安装所有防护罩和挡板。

常见问题解答

Common questions from buyers evaluating the GH Series for their fleet or implement build. If your situation is not covered, send us the details and we will respond within one working day.

What is your warranty policy and how do I make a claim?
The standard warranty is 12 months from the shipment date covering manufacturing defects in materials and workmanship under normal use. Extended 18-month or 24-month coverage is available for OEM contracts. For a claim, send a short video or photo showing the defect, the unit serial number, and a description of the operating context. We will respond within 24 hours and, if the claim is valid, supply a replacement or replacement parts free of charge.
What certifications do you hold and is your product suitable for Australian farms?
Production runs under an ISO 9001:2015 quality system. Gears are designed against ISO 6336 load-capacity calculations and DIN 3960/3961 accuracy classes. Units are CE-marked where required and reviewed against the Australian AS 4024 machinery safety framework. We have been exporting agricultural gearboxes to Australia for several years; the seal and lubricant specifications used on units bound for Queensland, NSW, Victoria, and Western Australia have been adjusted for the local dust, heat, and humidity profiles.
How long is the lead time for a stock order vs. a custom build?
Stock catalogue items typically ship within 7–15 working days after order confirmation, subject to current inventory. A custom build requires drawing review, sample (if required), and serial production — usually 30–45 days for a first batch and 20–30 days for repeat batches. Sea-freight is normal for full-container quantities; air-freight is available for urgent partial shipments at additional cost.
我应该使用哪种润滑剂，多久更换一次？
使用优质 GL-5（或至少 GL-4）齿轮油——SAE 80W-90 适用于大多数工况温度。在极寒气候下，请改用合成 75W-90 齿轮油。建议在 50 小时磨合期结束时进行首次换油；之后每 500 小时或每个季度更换一次，以先到者为准。旺季期间务必每周检查油位；即使短暂的低油位也会损坏齿轮组。
外壳是铝制的还是铸铁的？哪种更好？
Both are offered. Cast iron (HT250 / QT500) has higher strength and absorbs shock better — it is the right choice for continuous heavy duty such as feed mixers, big balers, and heavy tilling. Aluminum (A356-T6 or ADC12) is lighter and dissipates heat more rapidly — better for small implements that get moved frequently or where weight reduction is valuable. The GH Series is available in both cast iron and aluminum housings for this application.
