AI Technical Summary
Technical Problem
The existing bearing cage lacks effective initial positioning during assembly, which makes it easy for the upper and lower cages to misalign radially or circumferentially when tightening bolts, resulting in assembly difficulties.
Method used
The design employs a combination of positioning tubes and positioning holes. By inserting the positioning tubes into the positioning holes, the upper frame, lower frame, and positioning frame can be quickly positioned, ensuring the accuracy and smoothness of the assembly process.
Benefits of technology
It enables rapid positioning and accurate assembly of bearing cages, solving the assembly difficulties caused by the lack of initial positioning in existing technologies.

Abstract
This utility model relates to the field of bearing cage technology, specifically a bearing cage comprising a lower cage and an upper cage, wherein the upper cage and the lower cage are connected and fitted together, and several corresponding arc-shaped grooves are evenly distributed on their opposing sidewalls to form a mounting cavity for accommodating rolling elements; a positioning frame is disposed on the side of the upper cage away from the lower cage; a positioning mechanism is disposed between the lower cage, the upper cage, and the positioning frame; and an installation mechanism is disposed on the lower cage and cooperates with the positioning frame for fixation. This utility model, through the combined use of positioning tubes and positioning holes, achieves rapid positioning of the upper cage, lower cage, and positioning frame during assembly, effectively solving the problem of misalignment of the cage during bolt tightening caused by the lack of effective initial positioning in the prior art, ensuring smooth and accurate assembly.
