Robot harmonic reducer is a kind of power transmission organization, which uses the speed converter of the gear to reduce the number of revolutions of the motor (motor) to the required number of revolutions, and obtains a larger torque organization. The use of reducer is quite extensive, if the noise of the reducer is too large, it will hinder people's normal rest, learning and operation, and the low-noise reducer mechanism should be the subject of research and development of our reducer machine enterprises. What are the common accessories worn or damaged by the robot reducer? After years of research, many experts have proposed to optimize the gear parameters, such as displacement coefficient, tooth height coefficient, pressure angle, center distance, so that the meshing impact speed is minimized, and the ratio of the meshing impact speed to the meshing impact speed is at a certain value scale, and the gear design method of reducing or avoiding the impact of the meshing pitch circle can also significantly reduce the gear noise.
What are the common accessories of the robot reducer are worn or damaged, first of all, the gear wear, the gear wear mainly includes the tooth surface wear, the gear tooth is broken, the gear shaft hole or keyway is worn. In addition, the bearing hole of the reducer is worn, or the thread of the screw hole fails, in addition to the wear of the shaft surface of the reducer, the wear of the keyway and the bending of the shaft. The damage repair methods for these different accessories are as follows:
For the wear and tear of the shaft surface, such as the shaft hole and keyway, it is possible to restore the accuracy of the original part by electroplating. The bending of the shaft of the robot reducer can also be straightened by the press. There is no other way to deal with damage such as broken teeth but to machine new parts from scratch

Troubleshooting of small electromagnetic relay cores - Delta
The main problems of the iron core of the small electromagnetic relay are that the armature cannot be sucked after being electrified:
This may be due to broken coils, foreign matter between the moving and static cores, and low power supply voltage. It should be patched on a case-by-case basis.
When energized, the armature is noisy:
This may be because of the ...
