Worm Helical Gearbox

The worm helical gearbox is a hybrid transmission device combining the advantages of helical gears and worm gears. Its core features include low-speed heavy-duty operation, speed reduction with torque increase, and self-locking anti-reversal functionality.

It is widely used in industries such as lifting equipment, conveying machinery, and lifting platforms, where low-speed, high-torque transmission and anti-reversal safety are required. The combined transmission structure allows multi-stage speed reduction and torque increase, providing excellent self-locking performance that prevents equipment reversal when stationary, thereby ensuring operational safety.

The gearbox design complies with relevant gear and worm gear standards. It offers a wide range of transmission ratios and high reduction accuracy, making it well-suited for heavy-duty, low-speed, and high-safety applications.

• Helical Gears: 20CrMnTi alloy steel, carburized, quenched, and precision ground for high hardness, wear resistance, and smooth meshing.
• Worm Wheel: Tin bronze, offering high wear resistance and long service life.
• Worm: 40Cr alloy steel, quenched and ground, with a precision-ground meshing surface providing a large contact area for smooth and efficient transmission.
• Housing: HT250 gray cast iron, aged for enhanced rigidity and shock resistance.
• Sealing System: Fluororubber seals combined with labyrinth seals, providing IP65 protection against oil leakage and contamination.
• Process Technology: Precision machining and paired grinding processes ensure accurate matching between helical gears and worm gears, improving transmission efficiency and load capacity.

Excellent Speed Reduction and Torque Increase
Wide range of transmission ratios with high single-stage and multi-stage efficiency, enabling low-speed, high-torque output with broad rated torque capacity.

Self-Locking Function
Certain transmission ratios provide reverse self-locking, effectively preventing equipment reversal and enhancing operational safety.

Smooth Operation and Low Noise
Optimized transmission structure reduces operating noise, creating a quieter and more comfortable working environment.

Strong Adaptability
Supports multiple installation configurations. Transmission ratio and output shaft structure can be customized according to customer requirements.

Low Maintenance Costs
Uses long-life lubricating oil for extended oil change intervals. Highly interchangeable parts facilitate easy maintenance and reduce downtime.
