0° Spiral Angle Zerol Bevel Gear with AGMA 12 and DIN 5 Precision for High-Performance Robot Joints

0° Spiral Gears High Precision Grinding Fabrication For Robots

This set of 0° spiral gears (also known as Zerol bevel gears) for robots can be introduced from the following aspects:

1. Structural Classification
It is a special type of spiral bevel gear — the tooth profile is spiral - shaped, but the spiral angle at the midpoint of the tooth width is 0°. It belongs to the intersecting - axis gear transmission (the two shafts intersect perpendicularly), and combines the characteristics of straight bevel gears (simple structure, no axial force) and spiral bevel gears (smooth transmission, capable of high - precision grinding).

2. Core Performance Advantages
▶High Transmission Precision: It can be processed by gear grinding, and the precision can reach AGMA 12, DIN 5, or ISO 5 levels, which is much higher than that of ordinary straight bevel gears, meeting the “micron - level transmission precision” requirement of robots.
▶No Extra Axial Force: The force - bearing characteristic of the tooth surface is similar to that of straight bevel gears, eliminating the inward thrust of ordinary spiral bevel gears. There is no need to adjust bearings or installation structures additionally, which is compatible with the assembly conditions of straight bevel gears and reduces the structural design difficulty of robot joints.
▶Smooth Transmission & Low Noise: The tooth line is spiral, so the meshing contact is smoother. The linear speed can reach 60 m/s, and it is not easy to have edge contact and uneven load. The operating noise is low, which is suitable for the “quiet and high - speed” transmission scenario of robots.
▶High Strength & Impact Resistance: The tooth thickness is larger and the tooth length is longer. Compared with straight teeth and ordinary spiral bevel gears, it has stronger anti - fracture ability and can withstand the impact load during robot movement, improving the reliability of joints.

3. Application Value in Robots
Robot joint transmission systems have extremely high requirements for “precision, space, and reliability”:
▶Precision Adaptation: High - precision gear grinding makes the gear transmission backlash extremely small, ensuring the positioning accuracy of the robot's end effector.
▶Space Optimization: The orthogonal (perpendicularly intersecting axes) transmission form can be arranged compactly, meeting the design requirements of robot joints for “small volume and large torque”.
▶Reliability Guarantee: The characteristics of high fracture resistance, low noise, and smooth operation enable the robot to still transmit stably during high - frequency and long - term operation, reducing maintenance costs.

4. Comparison with Other Gears (Highlighting Advantages)

In summary, this set of 0° spiral gears has become a core component of robot joint transmission with the comprehensive advantages of “high precision, no axial force, smooth operation with low noise, and high strength”. It not only meets the requirements of precise motion control but also realizes reliable speed reduction and torque increase in a compact space.
