Bevel Gears with Extra-Long Shaft for CNC, Robotics & Automation Systems
The bevel gears (paired with extra-long integral shafts) are precision-engineered power transmission components, crafted via orthogonal grinding technology (to ISO 1745:2006-6 standards). This one-piece gear-shaft assembly combines the high-torque transfer of bevel gears with the extended reach of an integral shaft — ideal for tight-space, high-precision applications like CNC, robotics, and automation.
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.
Precision Manufacturing: Strict temperature control and uniform grain structure during forging/grinding.
Full Traceability: Batch-level material tracking for compliance with global industrial standards.
Customization: Tailored tooth profiles, shaft lengths, and materials to meet specific application needs.
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.
