1, journal oval or shaft bending. When the motor rotates, due to the rotor gravity and produce interference vibration, the vibration frequency is usually double the motor operating frequency. The bending of the shaft causes an unbalanced weight to rotate at an angular velocity around the static equilibrium position, with the result being the same as the rotor imbalance. Journal oval or shaft bending can be measured in the dial indicator in the car, the journal oval must be welded or brush plating after grinding round, DC Gearmotor the shaft must be corrected when bending processing;
2, armature imbalance. Due to the rotation of the imbalance caused by the quality of the role of centrifugal force, so that the role of the bearing has a rotating force, resulting in the motor and the basic vibration. When the air gap is not uniform, the main pole is not tight or the base, DC Gearmotor the end of the rigidity of the poor, will cause vibration intensified, so check the rotor is not balanced, must be re-dynamic balance;
3, the base, the cover of important bearing parts manufacturing error or operating deformation. Due to the base, the end of the rotor and other important support parts of the mating surface error tolerance, especially large and medium-sized motor running for a long time after the base, DC Gearmotor cover and other important bearing deformation, the motor in the run-time bearing interference Force, causing motor vibration;
4, bearing radial clearance is too large, the outer ring and the cover with the loose. In the assembly, the bearings should be qualified. Bearing and journal, DC Gearmotor bearing seat must meet the requirements, or to be sprayed or brushing process to deal with, to avoid poor bearing caused by vibration. For wear bearings, the motor running when the vibration noise frequency is higher, easier to judge, found that this situation should be replaced bearings;
First, the daily maintenance, DC Gearmotor the heat is a very important part of the process, especially in the daily use of the cooling fan is the key to prevent the cooling fan is dust is an important step, the daily maintenance and maintenance should pay attention;
Second, the daily replacement of carbon brush to be timely, why do you say? We all know that the process of running the motor, the carbon brush is a very important parts, DC Gearmotor you can make the motor more efficient operation, but it is easier Broken, so to be timely replacement;
Third, the line of inspection, DC Gearmotor the use of motor in the process of motor lines is very important, especially the aging of the line, and its prone to leakage caused by electric shock phenomenon, so the use of motor in the process of attention to the motor line Routine maintenance.
