[0002] Bearing housings are widely used in industrial equipment. They are installed between two devices that are far apart, and the devices at both ends are connected by a coupling to solve the problem of critical speed of long shaft systems.

[0003] The existing CN117570116A describes a high-speed rotating bearing housing sealing structure. The oil ring's right end face groove mates with the left end face groove of the end cover to form a labyrinth seal. Its function is to slow the outflow of lubricating oil. When the oil slinger ring rotates at high speed, a strong airflow is generated between the ring grooves, further preventing lubricating oil from overflowing through the end face seal, thus increasing the sealing effect. However, it has shortcomings: existing equipment cannot be quickly disassembled and assembled, its adaptability is poor, the sealing effect is limited, rotational stability is poor, and installation and adjustment are inconvenient. Therefore, a bearing housing sealing structure for bare iron magnets is needed to solve the above problems. Utility Model Content
