The robot speed reducer is a power transmission mechanism that uses a gear speed converter to reduce the number of rotations of the motor (motor) to the desired number of rotations and obtain a speed-changing mechanism. The application range of the robot reducer is quite extensive. If the noise of the reducer is too large, it will cause people to rest, study and work normally. The low-noise type deceleration mechanism should be the subject of research and development by our reducer companies. What are the common parts of the robot reducer that are worn or damaged? It is an important research paper in the industry to reduce the gear transmission noise during the operation of the robot reducer. After years of research, a large number of experts have proposed to optimize the gear parameters, such as the displacement coefficient, the tooth height coefficient, the pressure angle, and the center distance, so as to fall into the impact speed The minimum reduction, the ratio of staying impact speed to incorporated impact speed is within a range of values, and gear design methods that alternate or avoid inserting pitch circle impacts can also significantly reduce gear noise.

What are the common parts of robot reducer wear or damage, the first is gear wear, gear wear mainly tooth surface wear gear teeth broken gear shaft hole or keyway wear. In addition, the bearing hole of the reducer is worn, or the screw hole thread is invalid, and the wear of the shaft surface of these reducers, the wear of the keyway and the bending of the shaft, etc. The damage repair methods for these different accessories are as follows:

For the wear of these key surfaces such as the keyhole of the shaft surface and the shaft hole, electroplating can be used to restore the original part accuracy. The bending of the shaft of the robot reducer can also be straightened by a press. There is no other way to break such damage of gear teeth, only to rework new parts.
