Description

Technical Field

[0001] The utility model relates to the technical field of bearing seats, in particular to a bearing seat equipped with a ball bearing. Background Art

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy.

[0003] The bearing seat is an important component of the bearing. Its main function is to fix and support the bearing. It is located at both ends of the shaft. By supporting and fixing the bearing, the shaft and its connecting parts have a certain positional relationship. The bearing seat usually has a sealing device to reduce the contamination of the bearing. It is often used in low-speed, heavy-loaded and mechanical rotating parts that are difficult to lubricate and maintain. The bearing seat has a compact structure and is easy to install and maintain. It is suitable for bearings in different fields such as lifting and transportation machines.

[0004] However, most of the existing bearing seats have threaded holes opened inside and are then fixed with bolts. After the bearing seat has been used for a long time, the internal threads will wear due to vibration during operation, resulting in a decrease in the fixing effect, affecting work efficiency and work accuracy. In addition, the bearing seat needs to be disassembled when adding lubricating oil inside, which is not convenient. Utility Model Content
