Präzisions-Überlastschutz
Kalibriert, um bei exakten Drehmomentschwellenwerten zu trennen und so kostspielige Schäden an Getrieben, Lagern und Gerätemechanismen zu verhindern.
Funktionsweise – Funktionsprinzip
The wide angle joint uses a double-cardan joint design with a centering mechanism that maintains equal velocity between input and output shafts, even at extreme operating angles. Unlike a standard single U-joint (which causes cyclical speed variation at angles beyond a few degrees), the WA joint’s dual cross-bearing arrangement effectively cancels out these speed fluctuations. The result is smooth, vibration-free power transmission at angles up to 80°. This is achieved through precision-matched cross bearings, hardened bearing cups, and a rigid centering yoke that constrains both joints to operate at exactly equal but opposite angles.
Zurücksetzen-Methode: N/A — continuous-duty component
Am besten geeignet für: Tight-turn applications, orchard equipment, lateral-offset implements requiring extreme shaft angles
Typische Anwendungsszenarien in der Landwirtschaft
Pfahlbohrer
Absorbiert extreme Drehmomentstöße, wenn der Bohrkopf auf Gestein, vergrabenen Beton oder dichte Wurzelmassen trifft, und schützt so sowohl den Bohrantrieb als auch die Zapfwelle des Traktors.
Schneefräsen & Schneeschleudern
Schützt vor Beschädigungen durch Eisbrocken, gefrorene Trümmer und verdichtete Schneewehen, die plötzliche, extreme Drehmomentbelastungen auf die Laufradwelle ausüben.
Rotationsmäher und Schlegelmäher
Schützt das Getriebe des Mähwerks vor Beschädigungen, wenn die Messer auf versteckte Steine, Baumstümpfe oder Metallteile treffen. Der Drehmomentbegrenzer absorbiert die Stoßbelastung und verhindert, dass sie die Zapfwelle des Traktors erreicht.
Heuballenpressen & Rundballenpressen
Verhindert Schäden am Ballenpressmechanismus bei der Zuführung von Pressgut, bei Fehlern in der Garnwicklung oder beim Eindringen von Fremdkörpern, indem der Antriebsstrang getrennt wird, bevor schädliche Drehmomentwerte erreicht werden.
Rotationsfräsen und Kultivatoren
Schützt das Getriebe der Bodenfräse und die Zapfwelle des Traktors, wenn die Zinken auf vergrabene Steine, Wurzeln oder verdichtete Bodenschichten treffen, die extreme Drehmomentspitzen erzeugen können.

Installation & Usage Guide
Installation Steps
Step 1: Verify that the PTO shaft spline size matches the torque limiter spline specification (Various cross sizes). Clean all spline surfaces thoroughly.
Step 2: Slide the torque limiter onto the PTO shaft spline, ensuring full engagement. Secure with the provided push pin kit or retaining hardware.
Step 3: Connect the output side (yoke or splined shaft) to the implement input shaft or gearbox. Ensure proper alignment and secure all fasteners to the recommended torque.
Step 4: Apply grease through the grease nipple to lubricate the spline interface and internal components. Use lithium-based EP grease (NLGI #2).
Step 5: Perform a low-speed test run to verify correct engagement and smooth operation before full-power operation.
Safety & Maintenance Tips
⚠ Always disengage the tractor PTO before inspecting or servicing the torque limiter.
⚠ Use only genuine replacement parts specified for your series to maintain the correct torque rating.
⚠ Re-grease spline connections every 8 operating hours or as specified in your equipment manual.
⚠ Inspect for wear, cracks, or damage before each season. Replace worn components immediately.
⚠ Never operate with damaged or missing PTO shaft safety shields.
Selection Guide — Choosing the Right Model
Selecting the correct torque limiter requires confirming the following parameters:
✓ Required Torque Rating (Nm): Match the implement’s maximum operating torque plus a 20–30% safety margin.
✓ PTO Shaft Spline Size: Commonly 1 3/8″ Z6 (6-spline) or 1 3/4″ Z6/Z20. Verify both input and output spline requirements.
✓ PTO Speed: Standard 540 RPM or economy 1000 RPM — confirm your implement’s requirement.
✓ Connection Type: Yoke output for standard shaft tubes, splined shaft for inline assemblies, or flanged output for direct gearbox mounting.
✓ Overload Frequency: Frequent overloads favor auto-reset types (ratchet, friction, automatic). Infrequent but severe overloads suit shear bolt types.
✓ Environmental Conditions: Consider dust, moisture, temperature extremes. Sealed automatic and friction types offer superior protection in harsh environments.
