From practical experience, how to avoid bearing system problems of vertical motors?

Compared with the horizontal motor, the bearing system of the vertical motor is required to have its particularity. Because of the gravity effect in the vertical direction, the material and size of the selected bearing and its associated components are all special.

For the size of the bearing system and the shape of the parts, the design of the motor has reached the requirements, and the experience accumulated over the years is enough to ensure its applicability and rationality. However, in the actual anatomy of the faulty motor, there are always some Ridiculous questions arise.

The rationality of bearing selection

When the vertical motor is working, due to its large axial load, deep groove ball bearings or angular contact ball bearings with relatively large clearance should be selected. Generally, for motors of H250 and below, deep groove ball bearings can be selected, and for motors of H280 and above, angular contact ball bearings should be selected at one end.

Angular contact ball bearings can withstａnd radial and axial loads in a certain direction, and the size of the axial load that can be supported is related to the size of its contact angle.

Problems that are prone to occur in the assembly process

For deep groove ball bearings, in the assembling process, in order to ensure the convenience of the later operation and maintenance of the motor, the end marked with information on the bearing faces outwards, but its forward and reverse will not affect the operation of the motor; for angular contact balls Bearing, bearing assembly must take into account its directionality, must ensure that the rotor can be naturally seated, and ensure that the axial position of the motor affects the bearing during operation. If the bearing is in the wrong direction, the self-gravity of the rotor when the motor is running will cause the bearing to be damaged, resulting in quality problems in a short time.

The vertical motor has two ways of extending the shaft upward and downward. There are also two types of suspension type and lift type for the rotor part, but no matter which way, the end of the angular contact ball bearing with the inclined surface should always be upward. Balance the axial force with the rotor's own weight.

Problems that are prone to occur during the test process

For many motor manufacturers, due to the limitations of assembly equipment and tooling molds, the assembly process can only be horizontal, but if the test process is also used in the same way, especially for motors without feet on the base, the motor running process Putting the bearing in an abnormal stress state, on the one hand, has problems with the operation of the bearing, on the other hand, it will cause some quality misjudgments. Therefore, no matter in the process of assembly, test and storage, it is very important to follow the actual operation mode of the motor. necessary.

For the vertical motor, the flange cover is an important installation surface. During the rotation process, it should be ensured that it is in good contact with the test platform. If it is not placed properly, it will also cause adverse effects on the motor itself and the test results. .
