升降舞臺http://www.qdcbgg.com/不同心出現的斷軸問題，從驅動電機的輸出軸橫斷面可以看出，橫斷面的外圈較明亮，而越向軸心處斷面顏色越暗，最后到軸心處是折斷的，這就充分地說明了造成驅動電機輸出軸斷軸的主要原因就是電機和減速機裝配時不同心。
Off-axis stage movements different heart problems arise from the cross section of the drive motor output shaft can be seen, the cross section of the outer ring brighter, while the darker color to the axis of the section, and finally to the center of the shaft is broken, This fully explains the drivers of motor output shaft broken shaft of the main reasons is a different mind when assembling the motor and gear reducer.
　　
升降舞臺不同心出現的斷軸問題，當電機和減速機間裝配時同心度保證的非常好時，電機輸出軸承受的僅僅是轉動力，運轉時也會很平滑。然而不同心時，輸出軸要承受來自于減速機輸入端的徑向力，這個徑向力長期作用將會使電機輸出軸被迫彎曲，而且彎曲的方向隨著輸出軸轉動不斷變化。輸出軸每轉動一周，橫向力的方向變化360度。
Off-axis stage movements different heart problems arise, when the time concentricity between the motor and gear assembly ensure very good, the motor output shaft by merely turning force when the operation will be very smooth. However,misalignment of the output shaft to withstand the radial force from the input gear, the radial force will cause a long-term effect of the motor output shaft is forced to bend, and the bending direction as the output shaft rotates constantly changing. Per revolution of the output shaft, the direction of change of the lateral force of 360 degrees.

如果升降舞臺http://www.qdcbgg.com/同心度的誤差較大時，該徑向力使電機輸出軸溫度升高，其金屬結構不斷被破壞，最后該徑向力將會超出電機輸出軸所能承受的徑向力，最后導致驅動電機輸出軸折斷。當同心度的誤差越大時，驅動電機輸出軸折斷的時間越短。在驅動電機輸出軸折斷的同時，減速機輸入端同樣也會承受來自于電機方面的徑向力，如果這個徑向力同時超出了二者所能承受的最大徑向負荷的話，其結果也會導致減速機輸入端產生變形甚至斷裂。
If the error is greater when the concentricity of the lifting stage, the radial force of the motor output shaft temperature rises, its metal structure continue to be damaged, and finally the radial force will exceed the motor output shaft can bear the radial force, and finally causes the drive motor output shaft broken. When the error of concentricity greater the shorter the drive motor output shaft break time. Drive motor output shaft broken, while the input of the reducer will also bear the radial force from the motor areas, if the radial force both at the same time is beyond the maximum radial load can bear it, the results will be lead reducer inputs deformation or fracture.
