[0001] The utility model relates to the technical field of bearings, in particular to a retaining frame for a tapered roller bearing. Background Art

[0002] Tapered roller bearings are widely used in mechanical equipment. Their superior load capacity and rotational precision make them an essential component of transmission systems. However, the cage, a key component within the bearing, has the primary function of evenly distributing the rollers, preventing collision and misalignment, and ensuring smooth operation and longevity of the bearing.

[0003] Existing technologies typically require specialized tools or manual operation to disassemble the retainer, a cumbersome process that can easily damage the retainer and related components, shortening the bearing's service life. Furthermore, existing retainers lack effective securing and protective measures during disassembly, making them prone to accidental movement or dislodging. This increases operational risk and difficulty, hindering cleaning and inspection. Utility Model Content
