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

の 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: PTO速度と合わせて、ギアボックスに必要な正確なギア比を決定します。

Step 2: Operating Environment

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

Why it matters: Determines the appropriate seal grade, surface coating, and housing material specification

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: High-hour operations justify premium bearing and gear specifications for lowest cost per hour

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: 回転方向が間違っていると、作業機が損傷したり、有効な作業ができなかったりします。

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: 加工やアダプタープレートを一切必要とせず、直接ボルトオンで取り付けられます。

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: ギアボックスは、通常運転時に過負荷保護を作動させることなく、最大トルクを処理できなければならない。

Step 7: Output Shaft Type

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

Why it matters: 出力の不一致は高価なアダプタカップリングを必要とし、潜在的な故障箇所を生み出す。

🔧 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.

ステップ1：潤滑剤を注入する

注入口プラグを取り外し、レベルインジケーターに達するまで推奨ギアオイルをゆっくりと注入します。ギアボックスの取扱説明書に記載されている潤滑油グレード（通常はSAE 80W-90 GL-5または同等品）を使用してください。注入口プラグを元に戻し、手で締めた後、レンチでしっかりと締めます。ブリーザーキャップが清潔で、詰まりがないことを確認してください。

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

PTOドライブシャフトをギアボックスの入力シャフトから切り離します。フロアジャッキまたは天井クレーンでギアボックスの重量を支えます（一般的な重量：モデルによって15～70kg）。締め付け応力を均等に解放するため、すべての取り付けボルトを十字型に外します。古いギアボックスを慎重に下ろし、脇に置きます。

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

トラクターを始動し、低回転数（約300回転/分）でPTOを作動させます。異音（研磨音、うなり音、ノッキング音、カチカチ音など）がないか注意深く聞いてください。15～20分間低速で運転し、ギアボックスハウジングの温度を（注意深く）手で監視します。すべてのシールと取り付け面からのオイル漏れがないか確認してください。徐々に最高運転速度まで上げていきます。

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.

Step 7: Drain & Document Old Gearbox

Locate the drain plug on the existing gearbox and position a catch container underneath. Remove the drain plug and allow all oil to drain completely — inspect the oil for metal particles or discolouration that may indicate internal wear. Record the old gearbox model number, mounting bolt size, and shaft dimensions for reference.

⚠ 重要: 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.

⚠ Abnormal Grinding or Whining Noise

推定原因： Insufficient lubricant or incorrect oil grade

推奨される行動： Drain and inspect oil for metal particles. Refill with correct grade. If noise persists after oil change, bearing or gear inspection is required. Contact support for rebuild guidance.

⚠ Oil Leaking from Shaft Seals

推定原因： Overfilled oil level creating excess internal pressure

推奨される行動： First, check and correct the oil level — overfilling is a surprisingly common cause of seal leaks. Clean or replace the breather cap. If oil level is correct and breather is clear, the seal has worn and should be replaced using our seal kit.

⚠ 入力軸が回転している間、出力軸の回転が停止します

推定原因： Stripped gear teeth or broken gear

推奨される行動： まず過負荷保護装置を確認してください。ギアボックスに最近急激な過負荷がかかった場合は、これが最も可能性の高い原因です。マニュアルに従って、せん断ボルトを交換するか、スリップクラッチをリセットしてください。過負荷保護装置に異常がない場合は、ギアボックス内部に損傷があり、専門業者による修理が必要です。

⚠ 運転中の過度の振動

推定原因： Worn universal joints in the driveline

推奨される行動： 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.

⚠ PTO作動時にギアボックスから金属的なカチッという音がする

推定原因： Loose internal components or retaining hardware

推奨される行動： PTO作動時のみに発生する異音（運転中は発生しない）は、通常、ドライブシャフトのバックラッシュを示しています。ドライブシャフトの伸縮チューブの摩耗を確認してください。運転中に異音が発生する場合は、内部摩耗によるギアのバックラッシュ過多が考えられます。異音が徐々に大きくなる場合は、ギアボックスの点検を受けてください。
