Shanghai guzuo HD series spiral bevel gear reducer is a heavy-duty high-rigidity right-angle

steering gearbox. Adopting high-strength cast iron housing and precision hardened spiral bevel gears,

this gear reverser features large torque, high rigidity, stable transmission and long service life. It supports multi-directional shaft output and synchronous combination drive, widely used for heavy-duty industrial machinery requiring stable 90° power conversion.

Main Features

• 90° Right Angle Transmission: High-precision spiral bevel gear realizes vertical power steering, meeting diverse mechanical layout requirements.

• Cast Iron Heavy Housing: Thickened cast iron shell provides excellent rigidity, shock resistance and structural stability.

• Superior Load Capacity: Alloy steel gears with integral heat treatment ensure strong torque output and heavy-load performance.

• High Transmission Efficiency: Optimized gear meshing design reduces friction loss, transmission efficiency up to 96%.

• Diversified Shaft Types: Optional single shaft, double shaft, hollow shaft and customized shaft extension.

• Stable & Durable: Low vibration and wear resistance, suitable for long-term continuous heavy-duty operation.

Application Scope

Precautions

• HD gearbox has no self-locking function; brake device is required for vertical load working conditions.

• Avoid sudden heavy impact and frequent overload operation to protect internal spiral bevel gears.

• Replace lubricating oil regularly after long-time operation to maintain transmission stability.
