The 1623106600 / 1623106700 Gear Wheel is part of the timing and transmission system inside Atlas Copco screw and rotary compressors. Its primary role is to maintain smooth rotational coordination between moving components, ensuring the compressor delivers consistent airflow, stable pressure output, and mechanical reliability.
Because air compressors operate under continuous load, the gear must withstand high torque impulses, thermal expansion cycles, and long operating hours without losing dimensional accuracy or tooth alignment.
This gear is engineered with a special focus on rotational steadiness, controlled backlash, and long-term surface hardness, ensuring that even after thousands of hours, the gear maintains its intended performance profile.
Key Technical Features
1. Optimized Tooth Geometry for Smooth Engagement
The gear teeth are machined to a controlled involute profile that delivers predictable contact patterns during every rotation. This ensures:
- Smooth torque transfer
- Lower sliding friction between teeth
- Reduced shock loads during acceleration
- Minimized noise and vibration
In continuous-duty compressors, stable tooth engagement significantly extends the life of both the gear and its mating components.
2. High-Strength Alloy Steel with Excellent Core Toughness
The base material is selected to combine tensile strength with the ductility needed to absorb dynamic loads. Even when exposed to sustained high temperatures inside the compressor housing, the gear maintains structural rigidity and resists deformation.
This material is particularly effective for gears that must hold precise tolerances despite long-term mechanical stress.
3. Deep Case Hardening for Superior Wear Resistance
A multi-stage heat treatment process forms a hardened tooth surface capable of resisting scuffing, micro-fatigue, and abrasive wear. Meanwhile, the inner core remains tough and flexible to absorb impact forces.
This dual-layer structure results in:
- Stable tooth shape retention
- High resistance to pitting and micro-cracks
- Long operational lifespan under high RPM conditions
4. Precision Ground Teeth for Low Noise and Vibration
After hardening, the tooth faces undergo CNC grinding to achieve controlled backlash and excellent surface smoothness. This greatly reduces vibration inside the compressor and ensures:
- Lower energy loss
- Better lubrication film stability
- Improved reliability of the shaft and bearing assembly
The increased accuracy also contributes to more efficient rotor timing and compression performance.
5. Accurate Bore and Keyway Machining for Perfect Fitment
The gear hub is machined to maintain precise concentricity between the bore, keyway, and outer gear profile. This prevents shaft wobble or misalignment and ensures predictable rotational behavior during continuous operation.
6. Fully Compatible with Atlas Copco Compressor Platforms
The 1623106600 and 1623106700 models follow Atlas Copco dimensional standards, ensuring seamless replacement without adjustment or re-machining.
Working Principle
Inside the compressor, the Gear Wheel transfers power from the drive motor to the internal compression components. The precision of its tooth engagement affects:
- Rotor timing (for screw compressors)
- Pressure stability
- Mechanical efficiency
- Vibration level
- Overall noise output
A high-quality gear ensures that the mechanical assembly remains synchronized even when running for thousands of consecutive hours.
Manufacturing & Quality Control
Each gear is produced under strict industrial standards, including:
- Dimensional inspection with coordinate measuring machines (CMM)
- Hardness and case-depth verification after heat treatment
- Concentricity, runout, and balance testing
- Surface roughness and profile accuracy measurement
These steps ensure that every gear meets or exceeds OEM specifications.
