你知道为什么微型直流减速电机会断轴?

来源:http://www.jnmcd.com 发布时间:2019-08-09 浏览:
  我们的微型直流减速电机具有传输效率高、精度高的优点,这也是它受到企业青睐的原因,但在长期的使用中,经常会出现断轴现象,这引起了我们的注意,这是什么原因呢?

  Our miniature DC deceleration motor has the advantages of high transmission efficiency and high accuracy, which is also the reason why it is favored by enterprises. But in the long-term use, the phenomenon of axle breakage often occurs, which attracts our attention. What is the reason?

  微型直流减速电机在装配时同心度保证的非常好时,直流减速电机输出轴承受的仅仅是旋转力,运转时也会很轻松。然而直流减速电机与减速机连接不同心时,输出轴要承受来自于减速机输入端的径向力,这个径向力长期作用将会使电机输出轴被迫弯曲,而且直流减速电机轴弯曲的方向随着输出轴转动不断变化。直流减速电机输出轴每转动一周,横向力的方向变化360度。如果同心度的误差较大时,该径向力使电机输出轴温度升高,其金属结构不断被破坏,最后该径向力将会超出直流减速电机输出轴所能承受的径向力,最后导致直流减速电机输出轴折断。

  When the concentricity of miniature DC deceleration motor is guaranteed very well in assembly, the output bearing of DC deceleration motor is only subject to rotating force, and it will be very easy to operate. However, when the DC deceleration motor is not centrally connected to the decelerator, the output shaft must bear the radial force from the input end of the decelerator. The long-term effect of the radial force will force the motor output shaft to bend, and the bending direction of the DC deceleration motor shaft will change with the rotation of the output shaft. The direction of transverse force varies 360 degrees for each rotation of output shaft of DC deceleration motor. If the concentricity error is large, the radial force makes the temperature of the motor output shaft rise, and the metal structure of the motor is destroyed continuously. Finally, the radial force will exceed the radial force that the output shaft of the DC deceleration motor can bear, which will eventually lead to the breakage of the output shaft of the DC deceleration motor.

  微直流减速电机的同心度误差越大,驱动电机输出轴断裂的时间越短。因此,在驱动电机输出轴断裂的同时,直流减速电机输入也将承受电机的径向力。,因此,在装配时保证同心度至关重要。

  The bigger the concentricity error of micro DC deceleration motor is, the shorter the breaking time of the output shaft of driving motor is. Therefore, when the output shaft of the drive motor is broken, the input of the DC deceleration motor will also bear the radial force of the motor. Therefore, it is very important to ensure concentricity in assembly.
