RADIAL THRUST BEARING Russian patent published in 2005 - IPC

FIELD: precision engineering; production of radial thrust bearings.

SUBSTANCE: the invention is dealt with precision engineering, in particular, with production of radial thrust bearings. The radial thrust bearing contains an internal element, an external element and the solids of rolling located with a capability to transfer the radial and axial forces from one indicated elements of the bearing to another. The feature of the bearing is that the internal element and the solids of rolling are made in the form of the corresponding elements of the planetary conical crossed-helical gearing with axes of rotation converging in one point of all geared to each other pairs of elements. In the bearing a continuous conical crossed-helical gearing is provided. The bearing surface area of then internal element of the bearing is made profiled in the form of at least three formed on a conical surface helical convex surfaces, separated one from another by a conical surface. Each solid of rolling represents a conical component part, the bearing surface of which is made profiled in the form of at least two formed on a conical surface helical concave surfaces separated one from another by a conical surface. The internal bearing area surface of the external element of the bearing is made conical and represents a running pass for the conical surface of each solid of rolling.

EFFECT: the invention ensures reliable operation of a radial thrust bearing.
