CAGELESS BEARING OF GYROSCOPE Russian patent published in 2011 - IPC F16C19/22 F16C19/28 F16C33/34 F16C33/36 

FIELD: machine building.

SUBSTANCE: bearing consists of one-board external (1) and two-board internal (5) rings with races and of rolling bodies made in form of rollers (3, 4) of two-step type arranged between rings. Bigger step of rollers (3) of an upper tier with two sections contacts only the race of external ring (1) along a line, while bigger steps of rollers (4) of a lower tier contact only the race of ring (5) along a line. Less steps of rollers (3) contact bigger steps of rollers (4) along a line. Ring (1) is set on rolling bodies (3, 4) with preload setting, while rolling bodies (3, 4) roll at constant and similar rotation frequency into opposite sides in each of tiers. Diameters of bigger steps of rollers (4) contacting lesser steps of rollers (3) are equal. Rollers (3, 4) contact one another and races along three lines. Bigger steps of rollers (4) having one section contact a less step of roller (3) located in a middle section of roller (3). Ring (1) contains additional external one-board ring (2) and, for example, from three to five magazines filled with lubricant, They are made in form of holes of conic type where into there are installed nets-cartridges (6) filled with metal ceramics. Also, micro-processors can be arranged in these cartridges.

EFFECT: reduced noise, raised rotation frequency, durability and reliability of operation.
