This parallel shaft helical gearbox features a compact modular design, wide torque range, and exceptional durability, engineered to withstand continuous heavy loads, corrosive atmospheres, and variable operating conditions common in chemical plants. Covering model sizes F37 to F157, this series supports power inputs from 0.18KW to 200KW, with a maximum output torque of 18000N.m and flexible gear ratio options up to 273, even reaching ultra-high ratios over 10,000 when combined with secondary reducers. With multiple mounting and output configurations, it seamlessly integrates with diverse chemical processing equipment, delivering reliable, energy-efficient drive performance for critical industrial operations.
Designed for the high-load demands of chemical processing, our heavy duty parallel shaft helical gearbox delivers exceptional torque output and overload resistance, with a reinforced high-strength housing and precision-machined alloy steel gears that withstand frequent shock loads and non-stop operation. All gears are made of 20CrMnTi alloy steel, carburized and quenched to HRC58-62 surface hardness, ensuring long service life even in harsh industrial environments.
This series offers multiple installation options including foot mounting, hollow shaft mounting, flange mounting, torque arm mounting, and small flange mounting, with both solid shaft and hollow shaft output designs to fit complex equipment layouts in chemical facilities. It can be paired with various motor types, including explosion-proof motors, variable frequency motors, brake motors, and standard industrial motors, fully meeting the safety and operational requirements of chemical processing.
Our parallel shaft speed reducer for chemical industry achieves a transmission efficiency of up to 96% for two-stage transmission and 94% for three-stage transmission, significantly reducing energy consumption and operating costs for long-running chemical operations. Precision ground gears (DIN 6 accuracy) minimize vibration and wear, extending maintenance intervals and reducing unplanned downtime for critical chemical production lines.
