Helical Gear Speed Reducer

The helical gear speed reducer is an upgraded bidirectional transmission product in the FA series, designed for heavy-duty, bidirectional applications requiring flexible installation and high efficiency. It is widely used in industries such as papermaking, printing, and conveying machinery, where equipment often requires frequent forward and reverse rotation and diverse installation methods.

Building on the heavy-duty advantages of the FA series, the shaft structure has been optimized for smooth bidirectional power transmission. Multiple installation configurations are supported, making it an ideal solution that combines high performance with installation flexibility. The product complies with relevant international and domestic standards, and its performance has been rigorously tested to meet customers' bidirectional transmission and customized installation requirements.

• Gears: Manufactured from 20CrMnMoTi alloy steel, treated with carburizing, quenching, and precision grinding. This results in high surface hardness, smooth gear surfaces, and high precision, ensuring smooth meshing with minimal impact noise in both forward and reverse directions.
• Housing: Composite structure of gray cast iron and aluminum alloy. Critical components are cast iron for rigidity, while non-critical parts are aluminum alloy to reduce weight.
• Process Technology: Bidirectional gear meshing optimization ensures consistent transmission efficiency in both forward and reverse directions.
• Shafts: Input and output shafts are integrally forged with increased diameters for higher load-bearing capacity.
• Sealing System: Bidirectional sealing design provides protection during both directions of rotation. Achieves IP66 protection, preventing oil leakage and contamination from impurities.
