⚙ How the Agricultural UAV / Drone Gearbox Works — Mechanical Principles

Let us examine how the gearbox in a agricultural drone operates:

Subsystem	関数
PTO Input	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 deep groove ball bearings selected specifically for the load profile of aerial application applications.
Gear Reduction	Precision straight bevel gears inside the gearbox reduce PTO speed while multiplying torque to match the pump/rotor drive’s demands. While agricultural drones use electric motors rather than PTO gearboxes, the pump drive gearbox on large-capacity spray drones converts motor output to the precise pump speeds needed for accurate aerial application. Lightweight construction is paramount in this weight-sensitive application. The gears are manufactured from carburized alloy steel, ground to tight tolerances, and profiled for quiet, efficient power transfer.
Output Drive	The output shaft delivers converted power directly to the agricultural drone’s pump/rotor drive. The output coupling is engineered for zero-backlash connection, ensuring immediate power delivery. The gearbox mounts at the implement’s drive junction where the output drives the pump/rotor drive performing aerial application.
Sealing & Lubrication	The high-strength steel alloy housing acts as a heat sink with cooling fins for convective cooling. Internal splash lubrication with synthetic PAO 75W-90 ensures all surfaces maintain a protective oil film. Quad-Ring Seals at each shaft opening block contaminants while retaining lubricant.

🎯 Agricultural UAV / Drone Gearbox Sizing Guide — Get the Right Fit First Time

Getting the right gearbox for your aerial equipment requires confirming these seven parameters before you order. Our engineering team can help you through each step if needed.

1. Torque Demand
Calculate the peak torque your aerial application application generates — including shock loads from obstacles or material variations.
Importance: The gearbox must handle peak torque without activating overload protection during normal operation.

2. Output Shaft Type
Identify the coupling type on your agricultural drone — keyed, splined, flanged, or hollow bore.
Importance: Mismatched outputs require costly adapter couplings and introduce potential failure points.

3. Tractor PTO Speed
Check your tractor’s PTO specification — standard is 540 RPM or 1000 RPM.
Importance: Determines the input shaft spline size and the baseline for ratio calculation.

4. Mounting Bolt Pattern
Measure the bolt hole positions, centre distances, and overall envelope on your agricultural drone’s gearbox mounting flange.
Importance: Ensures direct bolt-on installation without any fabrication or adapter plates.

5. Existing Gearbox Identification
Record the brand, model number, and any part numbers from the nameplate of the gearbox being replaced.
Importance: Speeds up the matching process and ensures dimensional compatibility with your aerial equipment.

6. Rotation Direction
Determine whether the pump/rotor drive on your agricultural drone requires clockwise or counter-clockwise output when viewed from the drive end.
Importance: Incorrect rotation direction will damage the implement or produce no useful work.

7. Required pump/rotor drive Speed
Refer to your agricultural drone manufacturer’s manual for the recommended pump/rotor drive operating speed.
Importance: Together with PTO speed, this defines the exact gear ratio your gearbox needs.

💡 プロのヒント： Ordering tip: if replacing an existing gearbox, measure the input/output shaft diameters and mounting bolt pattern as a minimum. With these three dimensions, our team can match the correct unit from our catalogue or design a custom solution.

🔧 Technician’s Installation Manual — Agricultural UAV / Drone Gearbox

Follow these instructions for a successful installation of your new Agricultural UAV / Drone gearbox. Correct installation is critical for achieving maximum service life and warranty coverage.

Step 1: 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。

ステップ2：取り付け面を準備する

Clean the mounting flange on the agricultural drone 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 3: Position & Secure New Gearbox

Carefully lift the new Agricultural UAV / Drone 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 4: 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.

Step 5: Safety Preparation

Park the tractor on firm, level ground. Engage the parking brake and place wheel chocks. Turn off the engine and remove the key. Disconnect the PTO shaft from the agricultural drone. Allow all components to cool completely before touching. Wear appropriate PPE including gloves and safety glasses.

Step 6: Fill With Lubricant

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 7: Connect Output to pump/rotor drive

Attach the gearbox output shaft to the agricultural drone’s pump/rotor drive 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 8: 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。

⚠ 重要: Always consult the specific installation manual shipped with your Agricultural UAV / Drone gearbox for model-specific torque values and procedures.

🔎 Diagnostic Checklist — Agricultural UAV / Drone Gearbox

Use this diagnostic reference to identify and resolve common Agricultural UAV / Drone gearbox issues in the field. Most problems can be diagnosed and addressed without removing the gearbox from the agricultural drone.

⚠ギアボックスが過熱しています

推定原因： Incorrect oil grade (too thick or too thin for conditions)

推奨される行動： Check oil level and grade against the specification. Clean all debris from the housing exterior — especially the cooling fins. If the agricultural drone is being operated at or above the gearbox’s rated power, reduce forward speed or PTO load. Consider upgrading to synthetic gear oil for improved thermal performance.

⚠ PTOドライブラインとギアボックスの接続に問題があります

推定原因： Incorrect spline count (540 vs 1000 RPM mismatch)

推奨される行動： 入力シャフトのスプラインをワイヤーブラシで清掃し、焼き付き防止剤を薄く塗布します。PTOシャフトをゆっくりと回転させながら押し込み、スプラインを合わせます。スプラインがかみ合わない場合は、スプライン数がPTOの規格と一致していることを確認してください（540 RPMの場合は6スプライン、1000 RPMの場合は21スプライン）。

⚠ 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： Overload protection mechanism is loose

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。

⚠ 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： Internal shaft fracture

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。

⚠ Oil Leaking from Shaft Seals

推定原因： Scored or corroded shaft surface under seal lip

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.
