Optimized Axial Force Distribution Single Helical Gear for Energy-saving Metallurgical Rolling Mill Transmission

As a mechanical transmission component, helical gears transmit the rotational motion and torque of the input shaft to the output shaft through the meshing of spiral tooth surfaces, achieving the conversion of speed and torque.

• The axial force distribution can be optimized by adjusting the helix angle, balancing the radial load.
• It has a high transmission efficiency, generally reaching over 98%, which reduces energy loss.
• It can achieve a large gear ratio, with a compact structure that saves installation space.

By utilizing the axial component force of the spiral tooth surfaces, helical gears generate axial displacement compensation during the meshing process. This reduces local stress concentration caused by manufacturing errors, ensuring the stability of transmission.

It is used in scenarios with strict requirements for transmission efficiency and spatial layout, such as ship propulsion systems, metallurgical rolling mill transmission devices, and automated production lines.
