Single-pocket sectional type cylindrical roller bearing retainer

Abstract

The invention belongs to the field of bearings, and particularly relates to a single-pocket sectional type cylindrical roller bearing retainer which comprises a plurality of retainer body units, and the plurality of retainer body units form a whole retainer body; each frame body unit comprises a single pocket structure and two half pocket structures located on the two sides of the single pocket structure, and the half pocket structures of every two adjacent frame body units are combined to form an integral pocket structure. According to the retainer structure, an edge beam of a sectional retainer is omitted, a middle beam structure is formed, one independent retainer is installed every other roller, the problem that the beam width of every two adjacent retainers is doubled is solved, the bearing annular space occupied by the retainers can be reduced, the number of the rollers can be increased, and the bearing capacity of the bearing can be enhanced. Meanwhile, collision impact between the retainers is avoided, and the risk of breakage of the retainers is reduced.
