Ersatz für CMR-Getriebe mit Übersetzungsverhältnis 2,07:1 und fester Welle für Rundballenpressen

The EVER-POWER Ratio 2.07:1 Fixed Shaft Gearbox is an elite agricultural power transmission unit specifically engineered as a drop-in replacement for CMR round baler gearboxes. Delivering a precise 2.07:1 speed reduction, it converts standard 540 RPM tractor PTO inputs into the optimal rotational force required for high-density bale formation. Forged from premium AISI 4140 alloy steel and featuring a highly rigid fixed-shaft architecture, this gearbox eliminates the radial play often found in splined counterparts. Designed to meet DIN 6 and AGMA 10 accuracy classes, it ensures maximum torque delivery, exceptional thermal stability, and prolonged L10 bearing life in the most demanding global harvesting environments.

• Exact Ratio & Replacement Match: Delivers a strict 2.07:1 gear reduction ratio, perfectly replacing CMR and similar European OEM fixed-shaft gearboxes without any mechanical modifications.

• Rigid Fixed Shaft Design: Utilizes a solid, heavy-duty fixed shaft with a keyway to significantly reduce vibration and radial deflection during the heavy shock loads of crop compaction.

• Extreme Torque Capacity: Rated for 950 Nm of continuous torque and capable of withstanding 1450 Nm peak pulsating loads, ensuring zero power loss during wet silage baling.

• Advanced Metallurgy: Internal bevel gears are forged from 20CrMnTi and AISI 4140 steel, deep-carburized to HRC 58-62 for ultimate abrasive wear resistance.

• Superior Environmental Protection: Features an IP65-rated QT450 cast iron housing with double-lip oil seals, effectively keeping out crop dust, moisture, and abrasive field debris.

Umfassendes Produktwissen

What is a 2.07:1 Fixed Shaft Round Baler Gearbox?

A round baler gearbox is the primary kinetic bridge between a tractor and the baler’s internal mechanisms. The “2.07:1 ratio” indicates a speed reduction: for every 2.07 turns of the tractor’s PTO shaft (typically 540 RPM), the gearbox output shaft turns exactly once (yielding roughly 261 RPM). This reduction multiplies the torque, providing the immense twisting force needed to roll and compress heavy hay or silage into tight, uniform bales. The “fixed shaft” designation means the output shaft is a solid, integral piece utilizing a keyway for sprocket attachment, offering maximum structural rigidity.

Why is the 2.07:1 Ratio Critical for Baling?

Timing and speed are everything in round baling. If the internal belts or rollers spin too fast, the crop shatters, losing vital nutritional leaves. If they spin too slow, the baler clogs, and bale density drops. The 2.07:1 ratio is a kinematic standard used by brands like CMR to achieve the perfect balance of pickup speed and compression chamber rotation when driven by a standard 540 RPM PTO. EVER-POWER meticulously replicates this exact ratio to ensure your baler operates exactly as intended.

How Does the Fixed Shaft Design Enhance Stability?

During the final stages of forming a round bale, the radial tension on the drive chains and sprockets reaches its peak. Hollow splined shafts can sometimes suffer from micro-deflection under these extreme radial loads, leading to accelerated bearing wear. The EVER-POWER fixed shaft design utilizes a solid billet of 42CrMo alloy steel. This solid architecture virtually eliminates shaft deflection, keeping drive sprockets perfectly aligned and ensuring that heavy radial loads are transferred safely to the oversized tapered roller bearings.

What Materials Ensure Longevity in EVER-POWER Gearboxes?

Replacing a CMR gearbox requires matching European quality. Our internal bevel gears are CNC-machined from AISI 4140 and 20CrMnTi alloy steels. Through a highly controlled carburizing process, we infuse carbon into the surface of the gear teeth, achieving a hardness of HRC 58-62. This makes the teeth highly resistant to abrasive friction. Simultaneously, the core of the gear remains ductile to absorb sudden shock loads. The exterior housing is cast from QT450 ductile iron, absorbing operational vibrations.

How to Maintain the 2.07:1 Baler Gearbox?

Maximizing the lifespan of this transmission requires strict adherence to lubrication protocols. The gearbox relies on an internal oil bath splash system. It must be filled with 80W90 GL-5 Extreme Pressure gear oil. After the initial 50-hour break-in period, the oil must be drained to remove manufacturing micro-shavings. Thereafter, a 1000-hour or annual oil change interval will allow the gearbox to exceed its 10,000-hour L10 bearing life.

Installation Guide (HowTo)

Step-by-Step Installation

Proper installation is critical for ensuring the longevity of your new 2.07:1 fixed shaft gearbox. Please follow these engineering guidelines.

1. Altes Schmiermittel ablassen: Place a large drain pan under the old CMR gearbox. Remove the bottom plug and let all gear oil empty.

2. Disconnect Linkages: Loosen the tensioners on the main drive chains. Remove the output sprocket from the old fixed shaft.

3. Altes Getriebe ausbauen: Unbolt the primary PTO input shaft. Remove the base mounting hardware. The gearbox weighs approximately 38 kg, so use a mechanical lift.

4. Antriebsritzel einbauen: Slide the drive sprocket onto the new EVER-POWER fixed shaft. Insert the proper machine key into the keyway and secure it.

5. Montieren und Ausrichten: Hoist the new gearbox into place. Hand-tighten bolts, use a laser alignment tool to ensure the output sprocket is aligned, and torque the bolts to OEM specs.

6. Kritische Schmierung: Remove the top breather plug. Fill the gearbox with 80W90 GL-5 Extreme Pressure gear oil to the indicated level. Do not overfill.

Häufig gestellte Fragen (FAQ)

Technische Anfragen

• Ist dieses Getriebe ein exakter Ersatz für das CMR 2.07:1-Getriebe? Yes. It is engineered to replicate the 2.07:1 speed reduction ratio and perfectly matches standard mounting patterns and dimensions of CMR fixed-shaft gearboxes.

• Wann sollte ich den ersten Ölwechsel durchführen? Drain and replace the gear oil after the first 50 hours of operation. After that, change the oil every 1000 hours.

• Kann dieses Getriebe mit 1000 U/min betrieben werden? No. This specific 2.07:1 gearbox is designed for a 540 RPM PTO input.

• Does EVER-POWER manufacture the matching sprockets and chains? Yes! EVER-POWER can supply the exact drive sprockets, heavy-duty roller chains, and PTO shafts to accompany your new gearbox.

• How does EVER-POWER ensure quality? Every gearbox undergoes a strict Quality Control SOP, including CMM dimensional verification, dynamic load testing, and IP65 pressure leak tests.

• What happens if the gearbox overheats? Operating temperatures should not exceed 120°C. Overheating is typically caused by low oil levels or using the wrong oil type.

• Kann ich die Abtriebswelle individuell anpassen lassen? Yes. As a source factory, we offer full OEM/ODM services to customize the output shaft diameter and keyway dimensions.

• How quickly can you ship globally? We maintain a robust inventory and utilize global logistics networks to ship via expedited air freight or standard sea freight.

Anti-Halluzinations-Notizen

Technische Haftungsausschlüsse

• Please Note: While this gearbox is a direct mechanical replacement for specific CMR models, minor variations in shaft length or mounting hole diameters may exist across different manufacturing years. Always consult your OEM parts manual.

• All performance data (Torque limits, HP ratings) are based on rigorous factory testing under ISO/DIN standard conditions.

• Ensure your tractor’s PTO is set to 540 RPM. Over-speeding the gearbox will void the warranty and cause rapid mechanical failure.
