Sometimes the shaft of the reducer may be broken. Why does the output shaft of the reducer drive motor break? In order to solve this problem, the cross section of the output shaft of the reducer drive motor device is checked, and it can be seen that the cross section of the output shaft is the same as that of the reducer.
This can simply explain that the main factor leading to the broken shaft of the drive motor of the reducer is that the concentricity of the motor and the reducer device is different during operation.
If the concentricity loss deviation is large, the radial force will increase the temperature difference of the shaft transmitted by the motor, and the metal structure will be damaged. After all, the radial force will exceed the radial force that the motor output shaft can bear, and * * * will eventually break the output shaft of the driving motor.
When the concentricity of the motor device and the reducer device is relatively perfect, the energy received by the motor transmission is the ability of rolling, and the lubricity is also better during operation. However, in case of non concentricity, the output shaft shall bear the radial force from the input end of the reducer. The long-time effect of this radial force will force the motor output shaft to bend, and the bending direction will change continuously with the tumbling of the output shaft. The direction of the lateral force changes once the output shaft rolls.
In short, if the motor device and input position of the reducer are concentric, that is to say, the reducer and the motor operate closely and touch closely, and if the device is not concentric, there will be an open space between the contact surfaces between them.
When the fault of concentricity is greater, the time when the output shaft of the drive motor breaks is shorter. When the output shaft of the drive motor is broken, the input end of the reducer will also bear the radial force from the motor. Assuming that the radial force exceeds the * * * large radial load that they can bear together, the effect will also lead to deformation or even cracking of the input end of the reducer. Therefore, ensuring concentricity is the main way to prevent shaft breakage.
The above is the explanation of the factors why the reducer is not concentric and has a high probability of shaft breaking, as well as the relative measures to solve it.
