Precision Ground Orthogonal Gears and Long Integral Shaft for Industrial Drives
This precision-ground orthogonal gear set with an extra-long integral shaft is engineered for high-performance industrial drive systems that require exceptional accuracy, stability, and durability. Manufactured with advanced grinding technology and produced under ISO 17485:2006-6 standards, the gear set delivers superior meshing quality, reduced noise, and high transmission efficiency—making it suitable for demanding machinery applications.
This gear assembly consists of a spiral bevel gear pair (Z = 44:11, Modulus 3M) combined with a one-piece extended shaft. The integrated design eliminates joint weaknesses and ensures excellent coaxiality, making the product ideal for long-distance torque transmission and high-speed operation.
The ground tooth surfaces significantly enhance precision and reduce backlash, while the optimized geometry enables smooth, quiet, and efficient power transfer even under heavy loads.
90° intersecting shaft arrangement for compact and efficient power transfer.
Ensures smooth torque output with reduced vibration.
Suitable for complex reducer structures where space is limited.
Manufactured with gear grinding technology to achieve high tooth surface accuracy.
Reduces noise and backlash, ensuring stable performance even under continuous load.
Tooth profile and surface roughness are optimized for longer operational life.
One-piece shaft structure eliminates connection joints, improving rigidity and strength.
Reduces assembly errors and misalignment risks.
Provides better load distribution across bearings and gear teeth.
High-quality alloy steel (e.g., 20CrMnTi, SCM415) with carburizing and quenching process.
Surface hardness up to 58–62 HRC, ensuring excellent wear resistance.
Core toughness maintained for impact resistance and long fatigue life.
