Gearbox for Combined Tillage

High-Performance Agricultural Gearbox for Combined Tillage Applications

Productive multi-function tillage starts with dependable power transmission. The Combined Tillage gearbox we manufacture is a precision instrument — not a commodity part. The combined tillage gearbox is a multi-output unit that simultaneously drives discs, tines, and packer rollers from a single PTO input. Positioned centrally on the implement frame, it distributes power to each working element through separate gear trains.

From the hardened gear teeth to the heavy-duty shaft seals, every element is selected and assembled to deliver thousands of hours of trouble-free service. Australian farmers operating in dust, heat, mud, and moisture rely on this gearbox to perform consistently throughout the most demanding seasons.

🔧 Inside the Combined Tillage Gearbox — Engineering Principles

The gearbox in your combined tillage machine is a precision power conversion device. Let us trace the energy pathway:

Input: Capturing PTO Energy

Power enters through a precision-machined splined coupling accepting 540 RPM (1-3/8″) or 1000 RPM (1-3/4″) PTO output. The input shaft rides on spherical roller bearings selected specifically for the load profile of multi-function tillage applications.

Transformation: The Gear Train

Inside the housing, precisely meshed straight bevel gears convert PTO high-speed input into modified speed and amplified torque for the multi-shaft output. The combined tillage gearbox is a multi-output unit that simultaneously drives discs, tines, and packer rollers from a single PTO input. Positioned centrally on the implement frame, it distributes power to each working element through separate gear trains. Gear tooth profiles are case-hardened to HRC 58-62 and precision-ground, achieving 96-98% mechanical efficiency.

Output: Driving the Multi-Shaft Output

The gearbox output shaft connects directly to the combined tillage machine’s multi-shaft output, delivering torque-multiplied power for productive multi-function tillage. The output coupling is machined to precise tolerances for responsive, zero-backlash power delivery.

Protection: Sealing & Lubrication

A multi-layer protection system extends service life: grey cast iron housing resists impact and corrosion, VITON FKM lip seals block contaminants, mineral 85W-90 GL-4 maintains hydrodynamic film on all surfaces, and a breather vent equalizes pressure during temperature changes.

🎯 Combined Tillage Gearbox Sizing Guide — Get the Right Fit First Time

Use this step-by-step guide to identify the exact gearbox model for your combined tillage machine. Click each step for detailed instructions.

Step 1: Required multi-shaft output Speed

How: Refer to your combined tillage machine manufacturer’s manual for the recommended multi-shaft output operating speed

Why it matters: 结合动力输出轴转速，即可确定变速箱所需的精确齿轮比。

Step 2: Operating Environment

How: Assess exposure to dust, moisture, chemicals, and temperature extremes in your typical multi-function tillage conditions

Why it matters: 确定合适的密封等级、表面涂层和外壳材料规格

Step 3: Working Hours per Season

How: Estimate your annual operating hours for the combined tillage machine to determine appropriate service life rating

Why it matters: 高工时运行需要采用优质轴承和齿轮，以实现最低的每小时成本。

Step 4: Rotation Direction

How: Determine whether the multi-shaft output on your combined tillage machine requires clockwise or counter-clockwise output when viewed from the drive end

Why it matters: 旋转方向错误会损坏工具或无法产生有效功。

Step 5: Mounting Bolt Pattern

How: Measure the bolt hole positions, centre distances, and overall envelope on your combined tillage machine’s gearbox mounting flange

Why it matters: 确保直接螺栓固定安装，无需任何加工或适配板

Step 6: Torque Demand

How: Calculate the peak torque your multi-function tillage application generates — including shock loads from obstacles or material variations

Why it matters: 变速箱必须在正常运行期间承受峰值扭矩，且不会触发过载保护。

Step 7: Output Shaft Type

How: Identify the coupling type on your combined tillage machine — keyed, splined, flanged, or hollow bore

Why it matters: 输出不匹配需要昂贵的适配器耦合器，并且会引入潜在的故障点。

🔧 Technician’s Installation Manual — Combined Tillage Gearbox

Follow these instructions for a successful installation of your new Combined Tillage gearbox. Correct installation is critical for achieving maximum service life and warranty coverage.

Step 1: Fill With Lubricant

Remove the fill plug and slowly add the recommended gear oil until it reaches the level indicator. Use the lubricant grade specified in the gearbox documentation (typically SAE 80W-90 GL-5 or equivalent). Replace the fill plug and hand-tighten, then snug with a wrench. Verify the breather cap is clean and unobstructed.

Step 2: Position & Secure New Gearbox

Carefully lift the new Combined Tillage gearbox into position on the mounting flange, aligning all bolt holes. Insert mounting bolts hand-tight first, confirming proper alignment. Once all bolts are started, torque them in a star (cross) pattern to the value specified in the installation manual. Verify the gearbox sits flush against the frame with no gaps.

Step 3: Remove Old Gearbox

断开动力输出轴与变速箱输入轴的连接。用千斤顶或起重机支撑变速箱的重量（典型重量：15-70公斤，具体取决于型号）。按交叉顺序拆下所有安装螺栓，以均匀释放夹紧应力。小心地放下旧变速箱并将其放在一旁。

Step 4: Connect Output to multi-shaft output

Attach the gearbox output shaft to the combined tillage machine’s multi-shaft output drive coupling. For keyed connections, align the keyway and slide the coupling on, then secure with the retaining bolt and torque to specification. For splined outputs, apply anti-seize to the splines and verify full engagement before locking.

Step 5: Test Run & Break-In

启动拖拉机，低速运转（约300转/分）并接合动力输出轴（PTO）。仔细聆听是否有任何摩擦声、呜呜声、敲击声或咔嗒声。低速运转15-20分钟，用手（小心地）监测变速箱壳体的温度。检查所有密封件和安装接口处是否有漏油。逐渐提高转速至全速运转。

Step 6: Prepare the Mounting Surface

Clean the mounting flange on the combined tillage machine frame with a wire brush and solvent, removing all old sealant, rust, and debris. Inspect the mounting surface for cracks, stripped threads, or warping. Chase any damaged bolt threads with a tap. Apply a thin film of anti-seize compound to the mounting face if specified.

步骤 7：排空并记录旧变速箱

找到现有变速箱上的放油螺塞，并在下方放置一个接油容器。拧下放油螺塞，让所有油液完全排出——检查油液中是否有金属颗粒或变色，这些都可能表明内部磨损。记录旧变速箱的型号、安装螺栓尺寸和轴的尺寸，以备参考。

⚠ 重要提示： Always consult the specific installation manual shipped with your Combined Tillage gearbox for model-specific torque values and procedures.

🔎 Diagnostic Checklist — Combined Tillage Gearbox

Use this diagnostic reference to identify and resolve common Combined Tillage gearbox issues in the field. Most problems can be diagnosed and addressed without removing the gearbox from the combined tillage machine.

⚠ 异常研磨声或啸叫声

可能原因： Insufficient lubricant or incorrect oil grade

建议采取的行动： 排出机油并检查是否有金属颗粒。加注正确等级的机油。如果换油后噪音仍然存在，则需要检查轴承或齿轮。请联系技术支持以获取维修指导。

⚠ 轴封漏油

可能原因： Overfilled oil level creating excess internal pressure

建议采取的行动： 首先，检查并调整机油油位——机油加注过量是导致密封件泄漏的一个常见原因。清洁或更换通气盖。如果机油油位正常且通气孔畅通，则说明密封件已磨损，应使用我们的密封件套件进行更换。

⚠ Output Shaft Stops Turning While Input Rotates

可能原因： Stripped gear teeth or broken gear

建议采取的行动： Check the overload protection device first — this is the most likely cause if the gearbox was recently subjected to a sudden overload. Replace the shear bolt or reset the slip clutch per the manual. If overload protection is intact, the gearbox has internal damage and requires professional service.

⚠ 运行过程中振动过大

可能原因： Worn universal joints in the driveline

建议采取的行动： First check all mounting bolt torques — vibration frequently loosens fasteners, which then amplifies the vibration. Next, inspect the PTO driveline U-joints for wear or binding. Verify driveline angles are within specification. Finally, check the output coupling to the multi-shaft output for wear or damage.

⚠ 变速箱在动力输出轴接合时发出金属撞击声

可能原因： Loose internal components or retaining hardware

建议采取的行动： 动力输出轴接合时（而非运转过程中）发出咔嗒声通常表示传动轴间隙过大——检查传动轴伸缩管是否有磨损。如果咔嗒声在运转过程中出现，则可能表示内部磨损导致齿轮间隙过大。如果声音逐渐增强，则需要检查变速箱。

如果上述措施仍无法解决任何问题， 联系我们的技术支持团队 我们提供专家诊断服务。对于严重的故障情况，我们可以安排远程故障排除或派遣替换设备。
