Extreme Speed Maintenance Steps Of Ina Deep Groove Ball Bearing

Extreme Speed Maintenance Steps 

When INA Bearing operates under the load condition of 0.1C, the Speed Maintenance Steps contact stress between the rolling element and the contact surface of the raceway increases,

resulting in the increase of the working temperature of the bearing and the relative deterioration of the performance of the lubricant. Speed Maintenance Steps Therefore, the limit speed of deep groove ball bearing will be reduced accordingly.

For the range of C / = 10, the reduction of limit speed is very small, so it can be ignored, that is, F1 = 1.

For the radial bearing under combined load, the number of rolling elements under load increases, the friction resistance increases, the calorific value increases, the lubrication and Speed Maintenance Steps cooling conditions deteriorate,

and the force acting on the cage also increases. Therefore, the limit speed of deep groove ball bearing must be adjusted by multiplying a reduction factor F2 according to the bearing type and load angle.

If the limit speed of the selected INA Bearing cannot meet the use requirements, some improvement technical measures can be taken to improve it to meet the more Speed Maintenance Steps satisfactory requirements. Such as improving the bearing tolerance level;

Appropriately increase the clearance; Change to special materials and improve the structure of cage; Change the lubrication Speed Maintenance Steps mode, such as oil-gas, oil mist and jet lubrication; Improve cooling conditions, etc.

First, the detection method of bearing lubrication maintenance

Extreme Speed Maintenance Steps Of Ina Deep Groove Ball Bearing

Keep the lubricating oil circuit unobstructed during operation,

regularly check the sealing condition of seals, and replace damaged seals in time. Also Speed Maintenance Steps monitor the operation status from the noise. Lubricant and temperature monitoring. Because there should be a steady buzzing sound during normal operation,

deal with it in time in case of abnormality. The normal lubricant is clear and clean. If the lubricant has become dirty, there will be worn particles or pollutants. When the temperature rises, the operation will be abnormal.

Second, the specific steps of bearing lubrication maintenance

1. Importance of lubrication

Attach great importance to ina bearing lubrication technology. Lubrication can use oil film to separate the relatively moving rolling surfaces from each other, which will not fail due to excessive wear caused by rough point contact, and can also ensure stable performance and rotation accuracy during the predetermined service life.

2. Classification of lubrication

It is divided into grease lubrication and oil lubrication. The advantage of grease lubrication is that the Speed Maintenance Steps lubrication facilities are simple, the grease is not easy to leak, and has the ability to prevent water,

air and other impurities from entering. Therefore, grease lubrication is widely used in general. Lubricate with oil under heavy load, high speed, high temperature and other working conditions.

3. Usage of grease

The amount of filling should be appropriate. It shall be subject to one-third and one-half of the space filled in the shell of bearing and deep groove ball bearing. If the grease is added too much,

the grease will deteriorate or Speed Maintenance Steps deteriorate due to stirring and heat sweeping. At high speeds, fill only to one-third or less. When the rotating speed is very low, the housing space can be filled to prevent external abnormal physics from entering the INA Bearing.

4. Storage of bearings

The environmental requirements for its storage and storage are relatively strict, such as temperature, humidity, etc. Antirust oil shall be applied before leaving the factory. The room temperature shall be controlled at 0-25 ℃ and the relative humidity shall be maintained at 45% – 60%.
