Engineering and Functionality

High-Precision Gear Tooth Design

The 5536996900 GEAR ATLAS COPCO is manufactured using state-of-the-art hobbing and grinding technologies. The gear teeth are precision cut to ensure smooth meshing and uniform load distribution. This minimizes friction and wear between mating components, leading to quieter operation and longer lifespan of both the gear and its neighboring assemblies.

The accurate geometry of the teeth enables consistent torque transfer even in high-torque or shock-loaded applications. In Atlas Copco drilling systems, this translates to steady rotational motion of the drifter, which is crucial for efficient drilling penetration and reduced maintenance frequency.

Material Composition and Heat Treatment

Constructed from alloy steel with high carbon and chromium content, the 5536 9969 00 gear demonstrates exceptional hardness and toughness. Through case hardening and induction tempering processes, the gear achieves a dual-layer structure:

• A hardened outer layer that resists surface wear and scuffing.

• A tough inner core that absorbs impact and torque stresses.

This combination of surface strength and internal resilience makes the gear ideal for high-impact applications like those found in Atlas Copco’s rock drill mechanisms and hydraulic powertrains.

Dimensional Accuracy and Surface Finish

Each gear is manufactured to tight dimensional tolerances, ensuring optimal alignment with shafts and mating gears. The inner bore is ground to exact concentricity, minimizing imbalance during high-speed rotation. The black oxide surface finish provides an additional layer of protection against corrosion, humidity, and abrasive particles, extending the component’s operational life in dusty or moist environments.

Applications in ATLAS COPCO Machinery

The 5536996900 GEAR ATLAS COPCO serves as a key power transmission component across multiple drilling and mining machine systems. It is typically positioned within the drifter, rotation drive, or percussion unit, where it translates mechanical input from the motor or hydraulic pump into controlled rotational force.

This part number is compatible with a wide range of Atlas Copco models, particularly within the ROC series and Boomer drilling systems, including but not limited to:

• Atlas Copco Boomer 282

• Atlas Copco Boomer 353

• Atlas Copco ROC L8

• Atlas Copco ROC D7

• Atlas Copco ROC F9

• Atlas Copco COP 1838 / COP 2238 drifters

These machines rely on precise gear engagement to maintain synchronization between the feed, rotation, and impact systems during drilling operations. A defective or worn-out gear can lead to misalignment, reduced drilling accuracy, or even transmission failure. Therefore, replacing it with a high-quality OEM-equivalent component like 5536996900 GEAR ATLAS COPCO is crucial for sustaining optimal performance and equipment longevity.

Installation and Maintenance Guide

Step 1: Preparation

Before installation, ensure the entire transmission assembly is free from dirt, metal debris, and lubrication residue. Inspect the mating shaft and bearings for wear or scoring.

Step 2: Alignment

Align the 5536996900 GEAR ATLAS COPCO with its mating shaft using an appropriate alignment tool. Misalignment can cause uneven load distribution, leading to premature gear wear.

Step 3: Lubrication

Apply OEM-approved high-viscosity grease or synthetic gear oil to the gear teeth prior to assembly. The correct lubricant enhances performance and protects against metal-to-metal contact during operation.

Step 4: Torque Verification

Use a calibrated torque wrench to secure fasteners to OEM specifications. Over-torquing or under-torquing can affect the gear’s fitment and longevity.

Step 5: Operational Check

After installation, run the system at low speed to ensure smooth rotation without abnormal noise or vibration. Gradually increase load and monitor temperature rise in the gear housing.

Step 6: Routine Maintenance

Regularly inspect the gear teeth for signs of pitting or uneven wear. Replace lubricant as recommended by the machinery’s service manual. This preventive approach will extend the life of both the gear and the entire drive system.
