Description

Large bridge rolling element bearing

Technical Field

The utility model relates to a bearing technical field specifically is large-scale bridge rolling element bearing.

Background

The bearing is an important part in the modern mechanical equipment. Its main function is to support the mechanical rotator, reduce the friction coefficient in its motion process and ensure its rotation precision, and the lubrication method of the bearing is divided into grease lubrication and oil lubrication. In order to make the bearing function well, first, a lubrication method suitable for the use conditions and the purpose of use is selected. Oil lubrication is predominantly lubricious when lubrication alone is considered. However, grease lubrication has a characteristic that the structure around the bearing can be simplified, and the advantages and disadvantages of grease lubrication and oil lubrication are compared. The amount of the lubricant is needed to be paid special attention during lubrication, and no matter oil lubrication or grease lubrication is adopted, the service life of the bearing is influenced by insufficient lubrication when the amount is too small, and large resistance is generated when the amount is too large, so that the rotating speed is influenced.

When the existing large-scale bridge rolling element bearing is used, the stability is poor, and the bearing is easy to shake. Therefore, we provide a large bridge rolling element bearing to solve the problems set forth in the background art described above.
