Extended Shaft Spiral Bevel Gear Set Grinding gear fabrication
The gear assembly consists of an orthogonal spiral bevel gear pair combined with an extra-long integral drive shaft. The one-piece shaft design eliminates assembly errors and structural weak points, ensuring excellent concentricity and rigidity. Precision-ground tooth surfaces provide optimized contact patterns, significantly reducing vibration and operating noise.
Designed in accordance with ISO 17485:2006-6 standards, this gear set delivers consistent performance under continuous or high-load operating conditions.
Low-Noise Operation
Precision grinding ensures smoother tooth engagement and reduced meshing noise, suitable for noise-sensitive industrial environments.
Small Backlash & High Accuracy
Tight tolerance control improves positioning accuracy and transmission stability.
High Transmission Efficiency
Optimized tooth geometry enables efficient torque transfer with transmission efficiency exceeding 96%.
Long One-Piece Drive Shaft
Integral machining enhances strength, minimizes vibration, and ensures stable torque transmission over extended distances.
High Strength & Long Service Life
Manufactured from high-quality alloy steel with optional carburizing or nitriding heat treatment for superior wear and fatigue resistance.
