Double helical gears combine two helical gears with opposite helix directions along the face width, creating a distinctive "herringbone" shape. This unique configuration effectively cancels out axial forces generated during transmission, eliminating the need for additional balancing devices.

• Axial Force Balance: Opposing helix directions neutralize axial forces, reducing bearing loads and enhancing system stability.
• High Load Capacity: Superior contact ratio enables multiple simultaneous tooth engagement for heavy-duty applications.
• Smooth Operation: Gradual tooth engagement minimizes vibration and noise for quiet, efficient power transmission.

During operation, the left-hand and right-hand tooth surfaces of the driving gear push corresponding surfaces on the driven gear. The opposing axial forces cancel each other, transmitting only torque. This meshing action efficiently transfers rotational motion and power between shafts.

Ideal for demanding environments including:

• Marine propulsion systems
• Metallurgical rolling mills
• Mining machinery reducers
• Other high-power transmission systems
