High-Precision Spiral Bevel Gear Set - Custom Industrial Gears

The Spiral Bevel Gear Set consists of a high-performance Ring Gear (crown gear) and a Pinion Shaft with integrated splines. Engineered for intersecting shafts—typically at a 90-degree angle—these gears are the heart of advanced power transmission systems. By utilizing a curved tooth profile, they offer a superior alternative to straight bevel gears in terms of strength, noise reduction, and service life.

Technical Features & Advantages

• High Load-Bearing Capacity: The curved teeth provide a larger contact surface area, allowing the gears to handle massive torque and high impact loads.

• Smooth & Quiet Operation: The gradual engagement of the spiral teeth minimizes mechanical vibration and "gear whine," even at high RPMs.

• Exceptional Efficiency: Precision-machined tooth profiles achieve a transmission efficiency of 96%–98%, reducing energy loss.

• Premium Material & Treatment: Manufactured from high-strength alloy steel (such as 20CrMnTi) and carburized/quenched to HRC 58-62 for maximum wear resistance.

• Precision Spline Shaft: The pinion features a precision-cut external spline for secure, slip-free connection to drive shafts or gearboxes.

Applications

Our spiral bevel gears are critical components in demanding industries:

• Automotive & Heavy Vehicles: Main reducers and differential units for trucks, buses, and SUVs.

• Construction Machinery: Transmission systems for excavators, loaders, and cranes.

• Industrial Gearboxes: High-torque right-angle speed reducers for manufacturing lines.

• Agricultural Equipment: PTO drives for tractors and harvesters.

Installation & Maintenance Notes

• Matched Pairs: These gears are lapped and tested in pairs; they must be installed and replaced as a set to ensure perfect meshing.

• Precise Alignment: Proper axial adjustment is vital to keep the contact pattern centered, preventing premature wear.

• Lubrication: Use high-quality Extreme Pressure (EP) gear oil (e.g., GL-5) to protect the sliding tooth surfaces.
