Robot Grinding Bevel Gear High Rigidity Precise Torque Transmission

1. Robot joint adaptation angle
In the robot joint transmission scenario, this set of gears plays a key role in "space power steering + precise torque transmission". Through the special meshing design of the spiral tooth surface, the robot joint can not only realize the staggered commutation of the power axis (adapt to the complex layout of multiple joints), but also stably convert the output torque of the motor into joint rotation, like the swing joint of the wrist and leg of the robotic arm, relying on it to ensure the repeated positioning accuracy of ±0.1mm level, so that the robot grasping and walking actions are more accurate and coherent.

2. The performance of the technical perspective
From the point of view of performance, it has the technical characteristics of "high rigidity + low vibration + long life". The tooth surface is precision grinding, carburizing and quenching, with a surface hardness of HRC58 - 62, strong impact load resistance (can withstand 3 times the instantaneous impact of rated torque), and is not easy to be damaged by external force collision during robot welding and grinding; At the same time, the helical tooth meshing overlap is high (>2.5), the vibration amplitude is <0.05mm, the noise is <65dB, and the high-precision machining (transmission return difference is <1 arc minute), so that the robot joint movement is stable and quiet, and is suitable for the integration of collaborative robots and people.

3. The perspective of the value of technology iteration
It is a "differentiated filling" technology choice. This set of gears is optimized by spatial staggered shaft transmission, the rigidity is about 2 times that of harmonics, the life is increased by more than 30%, and a larger hollow aperture can be achieved (which is convenient for robot wiring and integrated pipelines), which solves the pain point of "high rigidity and flexible layout" in strong working conditions robot applications such as welding and handling, and promotes the evolution of robot transmission solutions to diversification and scenario-based.

4. The design and process perspective
In terms of design, it adopts the idea of "topology optimization + modularity". The tooth shape and modulus of the gear are optimized by dynamic simulation to adapt to the movement requirements of high-frequency start-stop and variable load of the robot joint. At the same time, it supports modular delivery, which can be directly integrated with the robotic arm joint to simplify the assembly process of the robot body. On the process side, combined with five-axis linkage processing and superfinishing grinding process, the accuracy and consistency of the tooth surface can be guaranteed, and even if it is mass-produced, it can also make the robot joint transmission performance stable and controllable, helping robot manufacturers shorten the R&D cycle and reduce the cost of customization.
