[0002] Slewing bearings are widely used mechanical components in industrial fields. They are responsible for the rotational motion of machines and bear various loads. A slewing bearing assembly is the assembly of various components into a complete, ready-to-use slewing bearing system. Slewing bearings typically consist of inner and outer rings, rolling elements, etc. Depending on different application requirements, slewing bearings can also be designed in various structural forms, such as single-row four-point contact ball bearings, double-row unequal diameter ball bearings, and single-row crossed roller bearings.

[0003] Slewing bearings can withstand large axial loads, radial loads, and overturning moments, ensuring stable and reliable operation of mechanical equipment. They offer rotational flexibility, enabling both axial and radial rotation, facilitating the operation of machinery. Because slewing bearings are typically manufactured using high-quality bearing materials and precision machining processes, they possess high wear and corrosion resistance, allowing for long-term use in harsh working environments without significant damage. With their compact structure, easy installation, and convenient maintenance, slewing bearings are widely used in large rotary devices.

[0004] Existing slewing bearing assemblies primarily rely on adhesive bonding for sealing. This involves using a specific adhesive to tightly adhere the sealing strip to the corresponding area of ​​the slewing bearing, achieving both sealing and dust prevention. However, this adhesive bonding method reveals a significant problem in practical use: replacing the sealing strip is extremely inconvenient. Because the sealing strip is firmly bonded to the slewing bearing with adhesive, removing it from the bearing and replacing it with a new one when it wears, ages, or becomes damaged often requires considerable time and effort, and may even necessitate the use of specialized tools or equipment. This not only increases the difficulty and cost of maintenance but may also affect the normal operation of the equipment and production efficiency. Utility Model Content
