1、 bearing wear too large bearings for a long time, the bearing gap occurs too large or uneven situation, leading to friction bearing fever, fear of the rotor and stator friction, it will directly damage the bearing. The most prone to vibration is the sliding bearing, because it has the viscosity of the oil shaft will float, and this can also bearing the weight, if the bearing weight the greater the wear will be faster.

2、 the base vibration in some cases, base vibration is too large, the base of the vibration frequency can be said that the speed of gear reducer, there may be pedestal design problems, leading to unstable operation of the state.

3、 the transmission misalignment When the gear reducer in the motor and drive calibration line is not good, prone to vibration, to adjust the calibration line, to re-install the drive and motor connection, this can stabilize the motor bearing rotation.

4、 the mechanical imbalance of the rotor here is the imbalance of the rotor is not static and unbalanced state of rotation, the rotor from the axis, the centrifugal force generated under the deflection produced abnormal vibration.

5、the rotor parts loosen the motor rotor parts: commutator, poles, pulleys, reducer will be used for a long time these loosening, the general situation, the rotor will have miscellaneous sound, the situation occurred the best As soon as possible, because a long time the consequences will become increasingly serious.
