The effect of the use of unsuitable bearings on the motor

In industrial manufacturing, the motor as a key equipment, almost everywhere. However, in this seemingly mature field, many engineers may overlook a seemingly small but crucial problem for motor life and performance, inappropriate bearing installation, selection or maintenance often lead to motor performance problems and even early failure, and the consequences of improper maintenance of these problems can be devastating.

1. Premature wear: Incorrect bearing selection may lead to premature wear. For example, the use of bearings with insufficient bearing capacity will cause premature bearing fatigue, increase the replacement frequency, and shorten the overall life of the motor. The solution is also very simple, according to the working environment, load and speed of the motor, choose the appropriate specifications and models of bearings.

2. Increase vibration and noise: improper installation causes the bearing clearance to be too large or skewed, which will increase the vibration and noise of the motor, ultimately affecting the stability and operation safety of the equipment. This requires training for operators to ensure that they operate according to specifications during the installation of bearings to avoid unreasonable bearing clearance or damage due to installation errors.

3. Overheating and reduced energy efficiency: poor lubrication or contaminated bearings will increase friction, leading to overheating problems. Overheating not only affects the efficient operation of the motor, but also may damage other critical components. It is necessary to check the bearing status regularly, maintain the good running condition of the bearing, prevent the deterioration of the lubricating oil, and also choose maintenance-free bearings.

Although the bearing is small, it plays an important role in the health of the motor. Every electrical engineer should attach great importance to the selection, installation and maintenance of bearings. Neglect of detail can lead to great loss. Attention to detail can extend the life of the equipment and ensure smooth production.
