The latest application field and effect of one-character teeth

The human tooth (Herringbone Gear) has achieved breakthrough applications in many high-end fields in recent years due to its unique "human" shaped bidirectional spiral tooth structure, which has significantly improved the performance and reliability of transmission systems.

Latest application areas

1. Wind power field:

The gearbox of large wind turbine needs to withstand high torque and alternating load. The chevron gear box can cancel the axial force through two-way spiral teeth, reduce bearing wear, reduce the failure rate by more than 30%, and extend the life to more than 20 years.

Aerospace:

In aircraft engines and helicopter main reducers, the chevron gear transmission system reduces weight while achieving a 15% increase in power density and a 20dB reduction in noise.

3 ship propulsion system:

The chevron gear is used in the main propeller of a ship. It can withstand extreme load impact and has a transmission efficiency of up to 98%. The vibration amplitude is only 1/3 of that of traditional gears.

4. New energy vehicles:

The high performance electric drive system of the electric vehicle adopts a chevron gear reducer, and the NVH (noise, vibration, acoustic roughness) performance is optimized by 40%, and the range is increased by 5%-8%.

5 robot joints:

In the collaborative robot joint module, the transmission accuracy of the V-shaped tooth reaches micron level, and the repeated positioning error is less than ±0.01 mm.

Application effects

Axial self-balancing: the bidirectional spiral tooth structure completely offsets the axial force, reduces bearing load, and extends system life.

Low vibration noise: symmetrical tooth shape eliminates meshing impact and reduces noise by 10-15 dB, suitable for precision environment.

Summary of core strengths

Axial self-balancing: no thrust bearing, more compact structure and lower cost.

Life and reliability: the failure rate is more than 50% lower than that of helical gear system.
