ROLLER BEARING SOLID CAGE Russian patent published in 2001 - IPC

FIELD: mechanical engineering. SUBSTANCE: invention relates to construction of solid cage of roller bearing manufactured from plastic by casting under pressure. Solid cage of roller bearing has two races coupled to each other by jumpers which form sockets for rollers. Jumpers have middle section with surfaces intended for interaction with conjugated surfaces of rollers and sections adjacent to races and carrying the middle section. Cage also includes facilities for damping of roller impacts. Jumper sections carrying middle section are made elastic-pliable and may be manufactured as channel-section bar or in the form of two parallel rectangular-section bars or as box-section bar.
