علبة تروس بديلة بنسبة CMR 2.07:1 ذات عمود ثابت لماكينات كبس القش الدائرية

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.

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.

إخلاء المسؤولية الهندسية

• 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.
