ROLLING BEARING COMPOSITE CAGE Russian patent published in 2013 - IPC F16C33/46 F16C33/54 F16C33/66 

FIELD: machine building.

SUBSTANCE: proposed bearing cage comprises U-shaped roller seats. U-like border of one of said seats is formed by locking between two laster elements 54 on ring-like element 51. The latter is absolutely solid and continuous for joint with sections of said laster elements 54. For relative positioning of elements 51, 54 with closure, they are shaped to preset laster elements on element 51 in radial and/or axial directions of element 51. Element 51 is provided with radial ledges in circumferential direction or recesses 52 made on one of its faces to extend axially. Elements 54 has axial end zones that enter edges or recesses 52 and identical cross-section or axial ends T-shape-reinforced. In compliance with second version, circumferential element is formed to make laster elements preset axial position, hence, preset distance between two circumferential elements. At the same time, laster elements are distributed in circumferential direction by external means while one of their ends makes a ledge to abut circumferential element edge zone.

EFFECT: perfected cage, ease of manufacture.
