The Speed Limit Maintenance Of Deep Groove Ball Bearings

wallpapers News 2020-04-03

If the limit speed and speed of the selected deep groove ball bearings cannot meet the requirements for use, some technical improvement measures can be adopted to increase it to achieve a more satisfactory condition. We can use some measures,such as increasing the bearing tolerance level, appropriately enhancing the clearance. Changing to exclusive materials, and improving the structure of the cage; changing the lubrication method, such as using oil and gas, oil mist, and jet lubrication; improving cooling conditions, etc.

1. Testing method for bearing lubrication maintenance

During the operation, the lubricating oil path should be kept clear, and the seal condition of the seals should be checked regularly, and the damaged seals should be replaced in time. Also, monitor the operating conditions, from noise. Lubricant and temperature monitoring. Because it should be a smooth buzzing sound during regular operation, it should be handled in time when there is an abnormality. The standard lubricant is bright and clean. If the oil has become dirty, there will be worn particles or pollutants. When the temperature rises, it will run. An exception will occur.

2. Specific steps for bearing lubrication maintenance

Lubrication can use oil film to separate the relatively moving rolling surfaces from each other. It will not fail due to excessive wear caused by rough point contact. It also guarantees stable performance and rotational accuracy during predetermined working life. Lubrication includes grease lubrication and oil lubrication. The advantage of grease lubrication is that the lubrication facilities are simple, the grease is not easy to leak, and it has a particular ability to prevent water, gas, and other impurities from entering. Therefore, grease lubrication is widely used in general and lubricated with oil under heavy load, high speed, and high-temperature conditions.

It is best to fill one-third and one-half of the space of the bearing and deep groove ball bearing housing. If too much fat is added, the grease will deteriorate or deteriorate due to stirring and sweeping heat. The storage and storage environment requirements are relatively strict, such as temperature and humidity. To ensure that they are coated with anti-rust oil before leaving the factory, the room temperature should be controlled at 0-25 ° C, and the relative humidity should be maintained at 45% -60%.
