End Teeth Design & Manufacturing Capability

Curvic Couplings

Curvic coupling technology provides high-precision radial positioning and self-centering capability between compressor gear shafts and connected rotating components. The precision-ground teeth ensure excellent repeatability and stable torque transmission.

Hirth Couplings

Hirth coupling designs offer high rigidity, compact structure, and superior positioning accuracy, making them suitable for high-speed compressor transmission systems requiring reliable mechanical locking.

Curved End Teeth

The curved tooth profile creates a large-area surface contact between mating teeth, improving load distribution and reducing localized stress during high-torque operation.

Customized End Teeth Solutions

OBT can design and manufacture customized end teeth according to different compressor shaft structures, operating conditions, and performance requirements, including:

· Sector end teeth

· Straight end teeth

· Curved end teeth

Precision Performance

OBT compressor gear shaft end teeth are manufactured to meet demanding precision requirements:

· Repeat positioning accuracy: ±1"

· Indexing positioning accuracy: ±2"

· Tooth contact area: ≥90%

· Tooth contact ratio: 100%

Advanced grinding processes ensure accurate engagement, excellent interchangeability, and long-term operational reliability.

High Torque Transmission Capability

The precision-ground end teeth provide a large tooth engagement area, improving tooth surface strength and root strength. This allows compressor gear shafts to transmit higher torque while maintaining stable operation under demanding conditions.

Accurate Positioning & Automatic Centering

The unique face-tooth design provides self-centering capability after engagement, ensuring accurate alignment between shafts, gears, and rotor components, reducing assembly errors and improving system efficiency.

High-Speed Rotation Stability

For high-speed compressor applications, end teeth couplings provide excellent rigidity and vibration resistance. The curved tooth design distributes loads evenly across the contact surface, minimizing:

· Tooth edge stress

· Local deformation

· Vibration caused by uneven contact

· Fatigue damage during repeated operation

Reliable Performance Under Extreme Conditions

Compressor gear shaft end teeth maintain excellent mechanical performance under:

· High rotational speed

· High temperature environments

· Heavy torque loads

· Continuous operation conditions

The optimized tooth geometry improves thermal stability, service life, and overall system reliability.
