Spiral Bevel Gear Pinion Grinding Gear Process For Robot Joint

Robot gears: require lightweight, large transmission ratio, and high precision.

1) Lightweight. The power of the motor is limited. Only the lighter the weight of the robot, the more effective work can be done. This requires the gears to be light in weight and small in number. Usually there are only 2-stage transmission or 3-stage transmission. Humanoid robots have many joints, many parts, and low power, so they have higher requirements for lightweight gears.
2) The transmission speed ratio is large. Due to the high speed of the motor and the low speed of the robot's joints, a large deceleration transmission is required between the motor and the robot's joint output. Coupled with the restriction of lightweight, the gear single-stage transmission has a large transmission ratio and a small number of pinion teeth to reduce the volume of the entire gear system.
3) High accuracy. The robot actuator is at the end, and the extremely small accuracy error of the reducer will be amplified dozens of times at the end, so the robot has very high accuracy requirements for each joint reducer.
