The geared motor is generally an ordinary DC motor, but a gear reducer is added in front of the ordinary motor. The reducer is generally used for low-speed and high-torque transmission equipment. The motor, internal combustion engine or other high-speed running power is used to achieve the purpose of deceleration through the gear with a small number of teeth on the input shaft of the reducer and the large gear on the output shaft. Ordinary The reducer will also have several pairs of gears with the same principle to achieve the ideal deceleration effect. The ratio of the number of teeth of the large and small gears is the transmission ratio.

The motor and the reduction box can be used in conjunction with the transmission through the gear train.

What is the reason why the motor of the reducer does not turn and the reducer does not turn? In the process of selecting the gear reducer or worm gear reducer, the power of the motor is too small, and the reducer appears when the reducer is too large. The case of not moving the motor. In addition, there is another situation that when a fault occurs, the reducer will not be able to run, commonly known as stuck. In addition, the load added in an instant is too large. At this time, the reducer cannot drive the operation, so the motor will not be able to carry the load in an instant. At this time, it is easy to cause the motor to burn out. Another is that the reducer does not run when the motor is turned on. This may be due to the stalled motor used. This will happen to the motor at this time.

The speed regulation failure of the gear reduction motor is generally caused by the damage of the motor itself.

1. There are impurities in the box, such as iron filings. It is best if the iron filings and impurities can be discharged after oil cleaning and the magnetic screw plug function of the oil drain hole of the box. If they cannot be discharged, it is recommended to unpack and clean them, otherwise once the impurities enter the bearing , the direct consequence is that the gear inside the box is broken, the bearing hole is worn out, and the entire reducer is scrapped; 2. The surface precision of the gear is not high, and there is no chamfering practice or gear grinding process, resulting in abnormal noise during the operation of the gearbox. If there is no gear grinding process, the gear will eventually have spot peeling and the like, which will eventually affect the use. In this way, the oil needs to be changed frequently, and check whether there are massive impurities in the oil. If there are massive impurities, it is recommended to stop using it; if the oil is always dirty and there are powdery impurities, the sound should be normal after running-in. 3. Monitor the temperature of the entire reducer box at all times, especially the temperature at the bearing position. If the temperature of some or one bearing is abnormal and higher than the others, it means that there is a problem with the bearing. As long as there is a problem with the bearing, it is basically fatal. question. 4. Installation problems. It is possible that internal gears or other structures are in frictional contact with the inner wall of the box. In this case, the temperature at the non-bearing part of the box will be higher than other places, which can be ruled out. In summary, the inspection method: check the temperature strictly at all times, change the oil frequently, and check the oil condition. As long as it is confirmed that there is a blocky substance or that there is a problem with the bearing, the whole vehicle must be scrapped if it is not stopped.
