[0002] A bearing seat is a key component in mechanical equipment for supporting bearings and bearing the weight of mechanical rotating components. It can accept comprehensive loads and has special structures for large and extra-large bearing seats. It has the characteristics of compact structure, sensitive rotation, and convenient installation and maintenance. Where there is a bearing, there must be a support point. The inner support point of the bearing is the shaft, and the outer support is the commonly said bearing seat. Traditional bearing seats are usually made by casting processes, such as cast iron parts or cast steel parts. Although these materials have good load-bearing capacities, there are many varieties of bearing seats.

However, in the existing technology, bearing seats often focus on their load-bearing capacity, and their vibration-damping effect only uses structures such as springs and dampers in cooperation, while ignoring their stability in high-vibration environments, thus reducing the use effect of load-bearing bearing seats. For this reason, we propose a casting structure of an efficient vibration-damping and load-bearing bearing seat to solve the above problems. Content of the Utility Model
