Quasi-Hypoid Gear Spiral Tooth Meshing For Robotic Joint reducer

This quasi - hypoid gear pair is a core component of robotic joint reducers, and can be introduced from the following aspects:

1. Structural & Transmission Logic
It consists of a small quasi - hypoid gear (with an ultra - long shaft) and a large quasi - hypoid gear. The two shafts are orthogonally staggered (perpendicular and offset), and power transmission is achieved through spiral tooth meshing. It can efficiently complete "speed reduction with torque increase + directional transmission" — converting the "high - speed, low - torque" of the motor into "low - speed, high - torque" at the joint while changing the rotation direction.

2. Core Performance Advantages
▶High Transmission Efficiency: With a transmission efficiency of over 95%, it is significantly more efficient than worm gear transmission, reducing energy consumption for robotic operations.
▶Strong Load - Bearing Capacity: The spiral teeth achieve continuous meshing with a high contact ratio, increasing the tooth surface contact area and enabling it to bear large torques, which meets the heavy - load motion needs of robots.
▶Low Noise & High Precision: The arc - tooth structure reduces noise by about 20 dB. Combined with precision grinding processes, it can ensure micron - level transmission accuracy, laying a foundation for the robot's precise positioning.

3. Application in Robotic Joints
It is widely used in robotic joints, especially in:
▶Humanoid/Collaborative Robots: In compact joints such as wrists and elbows, its "compact structure + high torque" characteristic helps reduce the joint volume while ensuring power output.
▶Industrial Robots: In heavy - duty joints, its high efficiency and load - bearing capacity support long - term continuous operation.
