The Atlas Copco 1614933000 / 1614933100 Gear Wheel plays a central role in the drive and timing assembly of the screw compressor. Its performance directly influences rotor synchronization, compression efficiency, vibration levels, and operating noise. Because screw compressors rely on exact phasing between the male and female rotors, the gear must maintain micron-level accuracy throughout thousands of operational hours.
This gear wheel is engineered to handle high rotational speeds, fluctuating torque, and continuous thermal variation. Its tooth geometry, core strength, and surface hardness work together to ensure long-term reliability with minimal dimensional change or wear.
Key Technical Features
1. Precision-Matched Gear Set for Accurate Rotor Timing
Unlike general machinery gears, these Atlas Copco gear models are manufactured as matched gear sets, meaning the tooth profile and pitch are calibrated to synchronize rotors with extreme precision.
This ensures:
- Consistent compression chamber volume
- Stable airend efficiency
- Zero rotor interference
- Lower internal leakage
The precise phasing contributes to reduced energy consumption and quieter operation.
2. High-Strength Alloy Steel for Heavy-Duty Torque Loads
Both models are produced from refined alloy steel with high tensile strength and strong impact resistance. This material maintains rigidity during sudden torque changes, preventing tooth deformation or micro-cracks. Even in applications involving long service cycles and elevated internal temperatures, the gear retains structural integrity.
3. Advanced Heat Treatment for Enhanced Surface Durability
The tooth surfaces are treated using a deep carburizing or nitriding hardening process, forming a hard outer layer while preserving a tough, shock-resistant core.
Benefits include:
- Superior resistance to adhesive wear
- Extended fatigue life
- Minimal tooth deformation
- Reduced risk of pitting, scuffing, or surface peeling
This thermal processing allows the gear to operate reliably in oil-immersed environments typical of screw compressors.
4. CNC-Ground Tooth Surfaces for Low-Noise Operation
To reduce vibration and ensure ultra-smooth engagement, the gear teeth undergo precision grinding, resulting in:
- Optimized surface finish
- Tight backlash control
- Balanced torque distribution
- Reduced operational noise
- Stable rotation even at high RPM
The ground tooth surface decreases friction and promotes consistent lubrication retention.
5. Excellent Lubrication Compatibility
The surface micro-finish and gear design ensure stable oil film formation across the entire rotating cycle. This enhances heat dissipation and minimizes direct metal contact, extending the working life of both the gear and the paired rotor shafts.
6. Perfect Fit for Atlas Copco Screw Compressor Systems
These gears match Atlas Copco’s strict dimensional and tolerance requirements, including:
- Inner bore accuracy
- Keyway machining
- Pitch diameter
- Side face perpendicularity
The result is a true drop-in replacement that requires no adjustment or modification during installation.
Working Principle
During operation, the gear wheel transmits torque from the drive system to the compressor rotors. Its accuracy determines the synchronization angle between the male and female rotors, which is essential for efficient compression.
Stable gear performance ensures:
- Smooth rotor rotation
- Reduced mechanical stress
- Optimized compression ratio
- Lower vibration and noise
Any deviation in gear accuracy would compromise airend performance; therefore, precision manufacturing is critical.
Manufacturing & Quality Control
Each 1614933000 / 1614933100 gear undergoes rigorous inspection throughout production, including:
- Tooth profile measurement with CMM equipment
- Hardness and depth testing after heat treatment
- Dynamic balance verification
- Concentricity and runout testing
- Surface roughness evaluation
This guarantees every gear meets OEM standards, ensuring long-term compression stability.
