Functional Role in Hydraulic Drifters

In high-frequency percussion systems, vibrations and torque surges can cause substantial stress on internal drive components. The rubber element coupling absorbs and redistributes these forces, protecting both the motor shaft and the percussion mechanism from premature wear.

Primary Functions:

• Transmits rotational power from the motor to the drifter mechanism

• Absorbs vibration and torsional shocks

• Compensates for small misalignments between connected shafts

• Reduces maintenance frequency and extends system longevity

By cushioning mechanical stress, the 2652299195 coupling ensures that the drifter maintains smooth and precise operation, even when subjected to continuous impacts during rock drilling.

Design and Engineering Features

The 2652 2991 95 RUBBER ELEMENT COUPLING ATLAS COPCO is meticulously engineered using advanced polymer technology combined with precision steel fabrication. Its compact, modular design ensures simple integration within Atlas Copco drifter systems.

Key Features:

• High Elasticity: The flexible rubber structure allows for controlled angular and axial misalignment, reducing stress on connected shafts.

• Dynamic Damping: Absorbs torsional vibrations that result from percussion and drilling loads.

• Corrosion-Resistant Core: The steel center is treated with anti-corrosive coating for maximum protection in harsh environments.

• Precision Fit: Machined bore and keyway ensure perfect shaft alignment, preventing slippage or mechanical play.

• Noise Reduction: Significantly reduces operational noise by dampening mechanical oscillations during high-speed rotation.

The result is a coupling that provides superior energy transfer, minimal vibration, and long service life, even under extreme load variations.

Material Composition and Durability

Composite Construction:

• Rubber Element: Formulated from industrial-grade elastomer, capable of withstanding repeated flexing, compression, and heat cycles.

• Metal Insert: Hardened and machined steel center, designed for optimal torque transmission and shaft coupling stability.

The combination of these materials creates a balance between flexibility and strength — the rubber dissipates vibration energy while the steel ensures mechanical rigidity.

Performance Under Stress:

The coupling’s flexible body absorbs dynamic torsion loads, reducing peak torque impact by up to 35%. This significantly lowers the risk of component failure in high-frequency drilling operations.

The rubber compound is resistant to oil, grease, and hydraulic fluids, ensuring longevity even when exposed to harsh working conditions commonly found in mining and tunneling environments.

Vibration Damping Mechanics

One of the most critical performance aspects of the 2652299195 , 2652 2991 95 RUBBER ELEMENT COUPLING ATLAS COPCO is its advanced vibration damping capability.

In rock drilling, every percussion impact generates torque fluctuations that propagate through the drive line. The rubber element coupling acts as a dynamic energy absorber, converting these vibration forces into micro-heat within the elastomer.

This mechanical isolation minimizes:

• Axial shaft stress

• Bearing wear

• Loosening of fasteners

• Gear backlash and resonance

By maintaining rotational stability, the coupling helps the drifter achieve consistent drilling accuracy and energy efficiency across various rock formations.
