当升降舞台http://www.iyunsun.com/电机和减速机间装配时同心度保证的非常好时，电机输出轴承受的仅仅是转动力，运转时也会很平滑。然而不同心时，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，而且弯曲的方向随着输出轴转动不断变化。输出轴每转动一周，横向力的方向变化360度。如果升降舞台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电机输出轴所能承受的径向力，最后导致驱动电机输出轴折断。
When concentricity time landing stage 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. 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.

当升降舞台http://www.iyunsun.com/同心度的误差越大时，驱动电机输出轴折断的时间越短。在驱动电机输出轴折断的同时，减速机输入端同样也会承受来自于电机方面的径向力，如果这个径向力同时超出了二者所能承受的最大径向负荷的话，其结果也会导致减速机输入端产生变形甚至断裂。
When the landing stage concentricity error larger, the shorter the drive motor output shaft broken 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.
