How can you tell if the bearing of a washing machine is damaged?

The main thing is to listen to whether the washing machine makes abnormal noise when it is rotating, and whether there is a large vibration when you touch the washing machine box. A normal washing machine is small for both when it is running.

The bearings on general equipment are not at risk of water immersion, but the washing machine bearings are easily damaged by water immersion and rust due to the aging and wear of the rubber sealing sleeve. Regular maintenance, replacement of rubber seals, and lubricating the bearings with disposable syringes can still extend the working life of the washing machine bearings.

Basic structure. comprise plastic cylindrical inner cylinder and the outer cylinder of the drum made of metal with at least one drain opening, described inner cylinder and outer cylinder are adapted, described inner cylinder is made up of base, cylindrical inner cylinder and port ring, one end of cylindrical inner cylinder is connected with base, the other end is connected with port ring, described cylindrical inner cylinder is made up of 2 or more side wall plates and 2 or more convex ridge plates are joined with each other, described side wall plate is the arc plate with four contour edges, and its four contour edges are connected with base, port ring and convex rib plate respectively, And a connection structure is arranged.

If the bearing of the washing machine is broken, it will be very noisy, which is mechanical noise! It rings before and after the power is off, and if the damage is severe, you can hear the abnormal sound of the bearing by turning the drum of the washing machine by hand.

What are the manifestations of the failure of the rolling bearing of the washing machine?

1. The rolling bearings in good condition will emit a slight humming sound when running.

2. If the sound is very loud, making a "gurgling" sound or "hard, hard" sound, there may be cracks in the inner and outer rings of the imported bearing, or there are pitting pits on the bearing raceway (commonly known as "pitting corrosion"), or it may be a lack of oil.

3. When the power is on, if you hear the sound of "click", wait for a while, close the end cover of the motor with the back of your hand, and the end cover is hot, indicating that the bearing is worn, causing the rotor and stator to rub against each other and heat up. If the rotor is rotated when the power is not on, it can rotate briskly, but it cannot start running after the power is on, indicating that the bearing is seriously worn. Similarly, pinch the end of the rotor shaft with your hand and pull it left and right, if there is a significant loosening sensation at the shaft end, it also means that the bearing is worn.

4. There are impurities such as iron filings and sand in the rolling bearing, and the motor will be accompanied by slight noise when it rotates. At this time, you can use a screwdriver against the end cover, and listen carefully with your ears close to the wooden handle, if you hear noise, it means that the bearing is not clean, and you should clean or replace the grease. Bearings are worn, cracked, pitted, and should be replaced.

If the bearing of the washing machine is damaged or malfunctioning, a loud noise can be heard when the washing machine is running, which is a mechanical noise and can be easily distinguished. And the rolling bearings in good condition.

When it is running, it only emits a slight humming sound, which belongs to the sound of the motor turning. In addition, we can also judge in the following ways. 1. When the washing machine is running, you can hear the "gurgling" or "banging" sound inside the washing machine, it may be that there is a crack in the inner and outer rings of the bearing, or there is some corrosion on the bearing raceway, and there may be a pit that the bearing lacks lubricating oil.

In this case, it is necessary to repair the cracks and pitting, and if there is a shortage of oil, apply some lubricating oil to solve the problem. 2. If you can hear the sound of "clicking" when the washing machine is running, and then close to the end cover of the washing machine motor with the back of your hand, you can obviously feel that the end cover is hot, then it means that the bearing is seriously worn, causing the rotor and stator to rub against each other and heat up.

At this time, it is necessary to stop using the washing machine, and let the maintenance personnel replace the worn bearings with new ones as soon as possible, and the problem can be solved. 3. If there are iron filings and sand in the rolling bearing.

and other small debris, when the washing machine motor rotates, it will be accompanied by a slight noise of "sand sand". At this time, the bearing should be cleaned and the lubricating grease should be replaced in time.

Effect.

If the bearing of the washing machine is seriously worn, it can no longer be used, if it continues to be used, it will cause a lot of noise, and it will be like a year-old pie when it is dried, which is easy to cause other failures. Therefore, if the bearing of the washing machine is broken, it will affect the use, and the bearing should be replaced at the after-sales service center.

Reasons why washing machine bearings can break:

1. The bearing itself is a wearing part, and the bearing working strip used in the washing machine is relatively poor and the environment is relatively poor, and the washing machine bearing will naturally be broken when running in a humid environment for a long time.

3. Due to the aging and leakage of the rubber sealing sleeve, the bearing of the washing machine is easy to rust and damage after being immersed in water.

4. It is recommended that users regularly overhaul the bearing of the washing machine, replace the rubber sealing sleeve, and fill the bearing with lubricating oil with a disposable syringe.

1.If the bearing is broken, you don't need to change the pair, just replace it.

2.A bearing is a mechanical element that restricts relative motion to a required range of motion and reduces friction between moving parts.

3.The design of the bearing can provide free linear motion or free rotation around the fixed axis of the moving part, or it can block the movement by controlling the vector of the normal force acting on the moving part.

4.The main functions of the bearing are as follows:1

When the vehicle is turning, keep the shock absorber rotating with the wheels to keep the steering flexible; 2.The outer ring of the pressure bearing is made of rubber, which can maintain the soft connection between the body and the shock absorber, and prevent the vibration caused by uneven road surface during driving from being transmitted to the body through the shock absorber.
