The reducer is a dynamic conveying mechanism. By adopting a gear reducer, the motor can achieve the required number of decelerations and obtain a larger torque. At present, the application range of the reducer has been widely used in the movement of transmission force and mechanism. From the construction of transport ships, automobiles, locomotives, heavy machinery, processing machinery and automated production equipment used in the machinery industry to the daily life of ordinary household appliances, watches and automobiles, its traces can be seen in almost all types of mechanical transmission systems . Its application work can see the application of the reducer from the angle of high-power transmission, small load to precise transmission, and in industrial applications, the reducer has the function of reducing speed and increasing torque. Therefore, it is widely used in speed and torque conversion equipment. Gear reducer is the most widely used one among the reducers, which are very common in metallurgy, textile, steel, automation machinery and other industries.
Whether it is a gear reduction motor or a gear reduction motor, there are usually many different categories of faults. Such as unstable voltage, incorrect installation of capacitors, failure of starter components, damage to gears, shafts, bearings, broken connecting wires, poor fixing, etc. There are many different names. However, its performance is usually divided into nine categories.
The following is a summary of various gear reduction motor faults:
1. The motor does not rotate when there is no load.
The reasons are: improper voltage; incorrect or unconnected capacitors; poor operation of single-phase motor starters; damaged gears, shafts, and bearings, etc.;
2. The motor does not rotate when loaded.
The cause of the fault may be that the motor or the motor is running over load, or the gear may be damaged;
3. Abnormal fever
The reasons for this failure may include: overload operation; voltage is too high or too low, bearing wear, etc.;
4. Too much noise
The cause of this failure is usually bearing damage and gear wear;
5. Unusually unstable running noise;
The reasons for this kind of situation are as follows: gear bearings are worn out or the motor is not well fixed, and flange screws are loose;
6. Too much vibration
When the vibration is too large, of course, you need to check whether the feet or the mounting screws on the flange are fixed. Other possible reasons are: insufficient oil, oil pollution, etc.;
7. Brake failure
The reasons for this type of failure usually include: too large or too small gap, which is generally called brake type failure;
8. Oil spill
Oil leakage usually causes the oil in the equipment to be quickly exhausted, leading to a series of problems such as heat generation and gear damage;
9. The coil is damaged.
The cause of this problem is usually more complicated. It may be a voltage problem or a current problem. In addition, the coil may be damaged if the capacitor is not properly installed or water enters.
