3115326401 / 3115 3264 01 DRIVER – Atlas Copco Rock Drill Spare Part

The 3115326401 / 3115 3264 01 DRIVER ATLAS COPCO is a critical internal transmission component designed to deliver controlled rotational energy from the drive assembly to downstream drilling elements inside hydraulic rock drills. Operating at the core of high-impact drilling systems, this driver plays a vital role in torque continuity, vibration management, and mechanical synchronization.

Manufactured from premium alloy bronze with precision-cut internal splines, this component is engineered to withstand constant cyclic loads, shock impulses, and abrasive environments typically encountered in underground mining, quarrying, and heavy civil construction.

At 3GEN Export, we supply this part as an OEM-grade replacement with dimensional accuracy, surface finish consistency, and metallurgical stability equal to factory specifications — backed by worldwide delivery in just 5 working days.

What Makes the 3115 3264 01 Driver Technically Unique

Unlike generic bushings or couplers, the 3115326401 DRIVER ATLAS COPCO performs simultaneous mechanical functions:

It transmits rotational force.

It absorbs micro-vibrations.

It maintains axial alignment between rotating assemblies.

It protects mating shafts from premature wear.

Its internal spline geometry ensures maximum contact surface while minimizing backlash. This directly improves drilling efficiency and reduces energy loss during percussion cycles.

The outer cylindrical surface is finished to tight tolerances, enabling seamless seating within the housing bore. Internally, hardened spline teeth engage precisely with the mating shaft, allowing smooth torque flow even under extreme load.

Material Engineering and Surface Treatment

The driver is produced from high-density bronze alloy selected for:

High compressive strength
Excellent fatigue resistance
Superior thermal stability
Natural anti-seizing properties

This material choice allows the component to operate reliably without galling, even in poorly lubricated conditions.

Surface finishing includes fine radial machining marks that promote oil retention, reducing friction and extending service life. Internal splines are CNC-cut for perfect symmetry and load distribution.

Primary Functions Inside Rock Drill Assemblies

The 3115 3264 01 DRIVER ATLAS COPCO serves as a mechanical bridge between the rotation motor and percussion components.

Its responsibilities include:

Transmitting rotational motion to the drill string
Maintaining concentric alignment of internal shafts
Dampening torsional vibration
Preventing direct metal-to-metal impact between hardened components

Without a properly machined driver, drilling systems experience accelerated wear, unstable torque delivery, and increased failure risk across adjacent parts.

Typical Applications

This driver is widely used in hydraulic rock drills and top hammer drilling units operating in:

Underground mining
Surface quarrying
Tunnel excavation
Foundation drilling
Slope stabilization projects

It is installed deep within the rotation group, making reliability absolutely essential.

Installation Recommendations

Professional installation is strongly advised.

Before fitting:

Clean the housing bore thoroughly.
Inspect mating shaft splines for wear.
Apply assembly lubricant evenly.
Verify axial seating depth.

Improper alignment during installation can cause uneven spline loading and reduce operational lifespan.

After installation, always perform a rotation test before returning the machine to service.

Common Wear Indicators

Over time, drivers may show signs of fatigue due to extreme cyclic loads.

Typical replacement indicators include:

Spline rounding
Increased rotational play
Metallic vibration noise
Irregular torque transfer
Visible surface scoring

Replacing the driver at early wear stages prevents secondary damage to shafts, housings, and rotation motors.
