What is the reason why the 6319 bearing cage used in the motor is broken?

The reasons for the breakage of the bearing cage are:

1. Insufficient bearing lubrication. The lubricating oil or grease is dried and not added in time (maintenance), and the lubricating oil or grease is not labeled correctly.

2. Impact load of the bearing. Intense vibrations in the shock load produce the impact of the rolling elements on the cage.

3. Cleanliness of bearings. The bearing is not well sealed in the bearing box, and dust enters, and the friction between the rolling element and the cage is added, so that the cage is damaged.

4. Mistakes in the selection of materials for bearing cages. All kinds of cage materials have certain temperature resistance and speed requirements, if the material selection is not right, it is also the cause of cage damage.

5. Installation problems. The bearings are not installed correctly, and the cage is damaged during installation.

6. Other reasons. If the coupling is misaligned, the bearing is skewed and the force is uneven; The belt is installed too tightly; Environmental issues, for example, can damage bearings or cages.

If the motor bearing cage is damaged, the cage will be stuck in the bearing first, resulting in the wear of the bearing;

Secondly, the balls will be piled up together under the action of their own weight, and the bearing will be stressed inconsistently, which will shorten the bearing life and accelerate the wear;

After the bearing is damaged, of course, the damage to the motor is fatal; Of course, after a short period of cage failure, it will not affect the use of the motor for the time being, but if it is found, it is best to replace the bearing as soon as possible.

Motor bearing, also known as motor bearing or motor bearing, is a special bearing specially used in electric motor or motor. The bearing used in the motor is a part that supports the shaft, it can guide the rotation of the shaft, and it can also withstand the parts that are idling on the shaft.

If the high-temperature butter is not added in time, the quality of the bearing is too poor, the hardness of the molten steel is not enough, and the shaft deformation is possible. . .

319 This bearing has an outer diameter of 200 mm, which is not small.

There are two possibilities.

1. When the bearing is produced and processed, the cage is not well built.

2 You knocked him out when you were installing it.

I don't know if you are broken in use or during assembly, a broken cage is a manifestation of bearing failure;

Broken during or after assembly, due to:

1. The problem of product quality when the bearing leaves the factory;

2. The assembly method is improper, and the stressed part is wrong;

If it is damaged in use, it is a normal phenomenon, and the bearing is a wearing part for the following reasons:

2. The lubricating oil is not clean;

3. The assembly position is incorrect, and the cage is stressed;

4. The bearing rolling element fails, resulting in damage to the cage;

5. The problem of product quality when the bearing leaves the factory;

That's all for it, but the specific problems need to be analyzed in detail, and they cannot be generalized.

Addressed from several aspects:

1.There is a problem with the force on the bearing.

2.There is a problem with the assembly clearance.

3.The bearing grease temperature is not high enough.

4.There is damage in the assembly process.

If the motor bearing cage is damaged, the cage will be stuck in the bearing first, resulting in the wear of the bearing; Secondly, the balls will be piled up together under the action of their own weight, and the bearing will be stressed inconsistently, which will shorten the bearing life and accelerate the wear; After the bearing is damaged, of course, the damage to the motor is fatal; Of course, after a short period of cage failure, it will not affect the use of the motor for the time being, but if it is found, it is best to replace the bearing as soon as possible.

The motor bearing cage is damaged, which leads to the motor vibrating violently, sweeping the chamber, and the current increases greatly to cause smoke.

It has nothing to do with the motor, but only with the bearing. As soon as the cage is broken, the position of the rolling elements is uncertain. I've ridden a bike and dropped one or a couple of steel balls.

The steel balls in the rolling bearing are not densely arranged, and when the cage is broken, there are fewer steel balls than the bicycle, what do you say?

It may be: the ball is out of sight, the shaft is not centered with the inner ring of the bearing, and it will shake and make noise in serious cases.

Hello! I don't know if you are broken in use or during assembly, a broken cage is a manifestation of bearing failure;

Broken during or after assembly, due to:

1. The problem of product quality when the bearing leaves the factory;

2. The assembly method is improper, and the stressed part is wrong;

If it is damaged in use, it is a normal phenomenon, and the bearing is a wearing part, and the reason is that there is a lack of rent

2. The lubricating oil is not clean;

3. The assembly position is incorrect, and the cage is stressed;

4. The bearing rolling element fails, resulting in damage to the cage;

5. The problem of product quality when the bearing leaves the factory;

That's all for it, but the specific problems need to be analyzed in detail, and they cannot be generalized.

Typing isn't easy, oh!

The reasons for the abnormal sound of the motor bearing are generally as follows:

1. Bearing problems: the clearance of the bearing assembly is too large, the bearing flower frame is damaged 2, and the bearing is short of oil.

If the temperature of the bearings at both ends does not rise rapidly in a short period of time during the operation of the motor, it is likely that the dynamic balance of the motor rotor is not good, so find a professional maintenance shop for maintenance!

Check whether the bearing bracket of the end cover is eccentric, whether the spindle is bent, and see if it is the bearing ringing or other noises such as fans.

It could be eccentric, or you heard it wrong, such as the sound of an electric current.
