How to add lubricating oil in the bearing, is there a special lubricating oil for the bearing, and w

The oil level is generally added above the center of the lowest rolling element of the bearing.

Bearing is an important component in contemporary machinery and equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy.

According to the different friction properties of moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. Among them, rolling bearings have been standardized and serialized, but compared with sliding bearings, its radial size, vibration and noise are larger, and the highest is also higher.

Rolling bearings are generally composed of four parts: outer ring, inner ring, rolling element and cage, strictly speaking, it is composed of six parts: outer ring, inner ring, rolling element, cage, seal and lubricating oil. It mainly has an outer ring, an inner ring, and a rolling element, which can be defined as a rolling bearing. According to the shape of the rolling elements, rolling bearings are divided into two categories: ball bearings and roller bearings.

Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts, mainly playing the functions of lubrication, cooling, rust prevention, cleaning, sealing and buffering.

For bearing housings:

The choice of oil is generally: bearing oil, mechanical oil or hydraulic oil can also be, mainly to choose viscosity, for bearings, try not to use extreme pressure additives (gearbox separately).

The oil level is generally added to the center of the lowest rolling element of the bearing. Too much is not good.

That's too big a question, it's not good.

The most important thing is that you don't have bounty points.

Usually, minor repairs to replenish the lubricating oil, according to the situation to remove some of the lubricating oil in the bearing, and then add a little lubricating oil.

Due to the difference in manufacturing accuracy and material uniformity, even the same batch of bearings of the same material and size are used under the same working conditions, and their service life is not the same.

In bearing tasks, not only rolling friction occurs between the ring, rolling elements and the support frame, but also sliding friction, which causes the bearing parts to wear out all the time. In order to increase the wear of bearing parts, maintain the accuracy and stability of the bearing, and extend the service life, the bearing steel should have good wear resistance.

What are the lubrication methods for bearings? The two main lubrication methods of bearings are: grease lubrication and oil lubrication. The type of lubrication to be used depends on the site of the application and the characteristics of the bearing.

The influence of lubrication on the performance of bearings can be mainly divided into the following aspects:

1. First of all, lubricate all parts of the bearing to reduce the friction and wear of the bearing;

2. Make the rolling contact surface of the bearing often form an appropriate oil film to prolong the fatigue life of the bearing;

3. The heat generated by friction or other reasons inside the bearing is taken away by lubrication;

4. Through lubrication, the bearing can be rust-proof and dust-proof.

There are two types of grease lubrication: a sealing method in which grease is filled in a sealed bearing in advance, and a grease feeding method in which an appropriate amount of grease is filled inside the housing and replenished or replaced at regular intervals. In addition, for machinery that has multiple bearings that need to be lubricated, a centralized grease supply method is also used in which pipes are connected to each lubrication place. Grease lubrication can be filled with grease for a long time without needing to be replenished, and the structure of its sealing device is also relatively simple, so it is widely used.

Oil lubrication is relatively simple. Regular lubrication can improve the service life of the bearing.

There is a grease nozzle, just use a grease gun to hit it in.

There is a special bearing lubricating oil for bearings, and the selection of bearing lubricating oil, generally speaking, must consider the following elements:

1. Appropriate viscosity.

As a lubricant for bearings, the most important thing is the viscosity of the oil at the service temperature. In operation, there must be sufficient viscosity to support the pressure, if the viscosity is not appropriate, there will be a loss of power, excessive temperature rise, burning and other phenomena.

2. Operating temperature.

The lubricating oil must be selected according to the temperature of the bearing in operation. The ideal bearing lubricant is one with low viscosity and low flow point. In addition, if the bearing needs to be exposed to high temperatures for a long time, it must have good oxidation stability, and there must be no oil that is easily volatile or carbonized on the bearing.

This is especially important when circulating the oil feed.

3. Bearing load.

When the bearing is under heavy load, the oil film on the bearing contact surface is easy to break, so it is necessary to have sufficient oil film strength. For example, when the load is heavy, it is sometimes necessary to use a high-viscosity oil that can create a strong oil film that is not easy to be squeezed out.

4. Running speed.

The operating speed must also be taken into account when selecting the appropriate lubricant. For fast rotational speeds, it is necessary to select a low-viscosity lubricating oil to prevent frictional resistance and temperature rise due to viscous friction. For example, in the case of large, low-speed journal bearings that operate under heavy loads, a high-viscosity lubricating oil is generally used to allow the oil film to support the heavy load.

Special purpose bearings will be specified special lubricating oil, such as rolling pressure bearing morgan oil, etc., ordinary bearing lubricating oil can be used, mainly selected viscosity, load and temperature and other parameters.

The excellent performance of high-temperature bearings in the process of operation is inseparable from the good bearing operating environment given by high-temperature bearing grease, but when the bearing temperature reaches more than 500 degrees, imported or domestic high-temperature grease basically cannot meet the requirements of use.

If it is divided according to whether the high-temperature bearing is to add high-temperature grease, it can be divided into two categories, high-temperature bearing +200 +550, which is the need to add high-temperature bearing grease, and the temperature bearing +550 +1400, which is the profit material itself for oil-free self-lubrication, and high-temperature bearing does not need to add high-temperature grease.

Plain bearings with sealed covers on both sides do not need to be lubricated. (Whether it is a rubber sealing cover or a stainless steel plate punch.)

Press-seal cover) before the high-temperature bearing leaves the factory, it has already been filled with the required high-temperature grease, so the new high-temperature bearing does not need to add high-temperature grease, but it still needs to be filled with high-temperature grease in subsequent use, which can prolong the service life of high-temperature sliding bearings.

The amount of grease and grease filled is through continuous trials and tests, as well as the best average value is calculated in the later use, and it is the best and most scientific scheme to get it, so generally speaking, the service life of high temperature bearing grease loss is equivalent to the service life of high temperature sliding bearing, Mobei network provides you with more basic bearing knowledge and the latest bearing supply and demand information, and then add high temperature grease specified by the manufacturer after a period of use, which is conducive to the durability of high temperature bearings.

High temperature resistant bearing grease.

It refers to the composite soap-thickened semi-synthetic lubricating oil, which is made with structural improvers, antioxidant preservatives and special anti-wear preservatives. The lubricating grease of high-temperature bearing also has the following functions: good high-temperature characteristics and air oxidation stability characteristics, which can prevent the deterioration of lubricating oil at high temperature and ensure the long-term use of lubricated parts at high temperature; Good adhesion and stability of mechanical equipment, as well as colloidal stability, can ensure the lubrication of parts; Good lubricity, which can protect the high-temperature sliding bearing and reduce wear; The comprehensive performance is strong, which can ensure a long service life of the plain bearing.

In order to ensure the effectiveness of high-temperature lubricating grease: high-temperature lubricating grease needs to be stored in a cool and dry place to prevent moisture and impurities from penetrating into and affecting product quality.

The bearings should be cleaned and buttered.

Lubricating oil is required for new bearings. The function of lubricating oil is to ensure that the bearing works stably and reliably, and the oil film has a certain vibration absorption capacity, which can reduce the internal friction and wear of the bearing, prevent burning and viscosity, and prolong the service life of the bearing. However, there will be many shortcomings after the bearing is lubricated, so it is necessary to ensure that the bearing has good sealing performance, otherwise there will be oil leakage.

It is best for car owners to regularly check the tightness of the bearing to prevent lubricating oil leakage.

The role of the bearing:

Bearings are components that fix and reduce the coefficient of friction of loads during mechanical transmission. Its main function is to support the mechanical rotating body to reduce the friction coefficient of the mechanical load of the equipment during the transmission process. According to the different friction properties of moving elements, bearings can be divided into rolling bearings and sliding bearings.

If there is no loss of lubricating oil, there is no need to replace it regularly during the life cycle of the shaft head bearing, and it can be used for life. If the shaft head bearing lubricant is lost, it needs to be added. The lubricating oil demand of the head bearing is very small, as long as the bearing rolls in the empty chamber can be smeared, it is usually checked regularly, and the lubricating oil should be added in time once the bearing is found to rotate abnormally.

Summary. If the motor does not have oil injection holes, you need to stop the machine, open the bearing sleeve of the motor and the oil cap on both sides of the bearing, and then add lubricating grease. Generally speaking, adding once every six months is sufficient.

Many of the motors produced now are equipped with oil injection holes, which can be refueled directly without stopping the machine. If it is a motor produced in the past, the motor with a frame size of more than 280 is also equipped with its own oil injection hole, and it can also be refueled directly without stopping the machine. If the motor does not have oil injection holes, it needs to be stopped, open the bearing sleeve of the motor and the oil cap of the collapsed scum on both sides of the bearing, and then add lubricating grease.

Generally speaking, it is enough to quietly add once in half a year.

The problem is: it is strictly forbidden to boil the bearings from above the oil basin ().

That's it.

The whole problem is this.

When boiling bearings, the working area should be kept away from the flammable environment to prevent () it is strictly forbidden to bracket from the top of the oil basin.

It's the content to be filled in.

Cause a disaster.

What are the options.

I know it's a fire in the front of the blank.,I just don't know what to fill in the back.,It's a fill-in-the-blank question with no options.。

Inject Class A and B liquids.
