Shunli Motor FF-M10VA Micro DC Gear Motor 1mm Diameter

Briefly introduce the deceleration motor (deceleration motor) keyway problem related knowledge, that is, deceleration motor (deceleration motor) keyway damage reason and treatment method.

1. Reasons for damage

1) The coordination gap between the active wheel of the decelerating motor (decelerating motor) and the shaft extension end of the decelerating motor (decelerating motor) is too large. When the decelerating motor (decelerating motor) runs at a high speed, the friction is caused by loosening, resulting in unilateral or bilateral peeling off of the keyway.

2) When the flat key is assembled on the rotating shaft of the deceleration motor (deceleration motor), the keyway depth of the shaft extension end of the driving wheel and deceleration motor (deceleration motor) is not made according to the matching size, so that the unilateral force is not good and damaged.

3) During the operation of the decelerating motor (decelerating motor), the maintenance personnel do not operate according to the operation rules of the decelerating motor (decelerating motor), and hit the end of the flat key, which causes excessive extrusion between the flat key and the rotating shaft of the decelerating motor (decelerating motor), resulting in unilateral or bilateral fracture of the keyway.

4) The processing of the flat key material is not made according to the production, and its stiffness is greater than the stiffness of the deceleration motor (deceleration motor) rotating shaft material and damage.

5) The center line between the active wheel and the passive wheel of the deceleration motor (deceleration motor) is not in a straight line. When the flat belt or triangle belt drives, the flat key produces torque and damages the keyway.

2. Treatment methods

1) Use waste carbon brush to make fake keys, whose size is slightly smaller than the damaged keyway by 0.1~0.2mm, and place the fake keys in the damaged keyway.

2) The weld temperature is flush with the axial surface, and the false key can be removed after cooling. Use portable grinder or fine file to repair, and drive wheel to meet the requirements.
