Causes of Failures During the Running-In Period of Geared Motors

After a gear reduction motor arrives, the user should not rush to put it into normal use. It usually takes about 300 hours of running-in time, which is determined by the technological characteristics of the equipment. The running-in period can allow the equipment to operate normally in the future, reduce the occurrence of failures, and increase the service life. However, some users found that the equipment failed during the running-in time. What is the reason?

Running-In Period of Geared Motors

The reasons for the failure of the geared motor during the running-in period are as follows:

1. Fast damage

Because the new equipment is affected by the parts, assembly and debugging, and the contact area of the joint surface is relatively small, the torque used is relatively large. During the operation, the uneven part of the part surface will have fitting friction. The metal debris falling from the grinding will be used as an abrasive again, and friction will occur again, which will lead to aggravated damage to the joint surface of the parts.

During the running-in period, it is very likely that the equipment will have problems due to damage to the parts, especially the joint surface of the parts. Especially the high-load operation of the equipment is more likely to cause damage to parts and malfunctions.

2. Many wrong operations

Some operators are not very familiar with the newly purchased equipment, so they do not have much understanding of the structure and performance of the equipment, which may cause errors during operation, cause the equipment to fail within the running-in time, and may even cause mechanical failure in severe cases. accidents and safety incidents.

3. Improper lubrication

The bonding gap of the newly assembled parts is generally relatively small. In addition, due to the reason of just assembling, the lubricating oil does not produce a very uniform oil film on the friction surface, so the lubrication effect is not very good. If the situation is serious, it may even cause scratches or bites on the precision-bonded friction surfaces. Therefore, it is necessary to do a good job of lubrication during the running-in time.

4. Looseness occurs

Newly assembled parts may have deviations in geometric shape and matching dimensions, especially during the running-in period, when the parts are easily subjected to alternating loads of shock and vibration, causing the originally fastened parts to loosen. In addition, because the parts are affected by heat and deformation during operation, the parts will also become loose.

5. Leakage occurs

Due to the heating of the equipment and the influence of factors such as loose parts and vibrations, leakage occurs at the sealing surface and the connecting pipe. Due to the rough manufacturing process and hidden parts during assembly and debugging, some parts are difficult to find before use, but during use, these leaks that have not been found before will be exposed due to vibration and other reasons , more performance as oil leakage.

The failure of the geared motor during the running-in period may be caused by fast damage, many wrong operations, improper lubrication, looseness and leakage.
