ROLLING RADIAL THRUST CAGELESS BEARING Russian patent published in 2010 - IPC F16C19/22 F16C19/28 F16C33/34 F16C33/36 

FIELD: machine building.

SUBSTANCE: invention refers to machine building and can be implemented in all branches of industry. The rolling bearing consists of external ring (1) and one bead internal ring (4) with rolling grooves and of installed rollers (2) and (3) of two-stage type. A bigger stage of rollers (2) of an upper tier with two sections contacts in line only with the rolling groove of the ring (1), while bigger stages of rollers (3) of the lower tier contact in line only with the rolling groove (4). The lesser stages of rollers (2) made with three sections contact in line with the bigger sections of rollers (3) with constant and similar rotation frequency. Ring (1) consists of two protecting washers (6), while ring (4) contains thrust ring (5). Two sections of bigger stages of rollers (2) enter grooves of lesser stages of rollers (3) with a gap. Rollers (2) and (3) contact each other and rolling grooves in three lines forming load bearing integrated closed circular assembly of rollers (2) and (3). Two sections of spherical type made on bigger stages of rollers (2) bear axial load, while a contact patch is equal to diametre of the rolling groove of ring (1) in zones of triangular bores. Two end-thrust bearings (7) are arranged on rollers (3) along axis of the roller; these end-thrust bearings contact planes of higher beads of rings (4) and (5).

EFFECT: facilitating two-side axial force transfer, pure rolling friction at transfer of axial and radial loads, reduced noise, increased hoisting capacity, frequency of rotation and service life, and also increased operation reliability.
