BEARING ASSEMBLY (VERSIONS) AND METHOD OF BEARING MOUNTING IN CASING (VERSIONS) Russian patent published in 2015 - IPC F16C11/06 F16C17/12 

FIELD: machine building.

SUBSTANCE: invention on the whole is related to a bearing, in particular, to the installation of a spherical bearing in a bearing assembly to be used in aerospace engineering. A bearing assembly (100) and method to form the bearing assembly comprising a casing (110) with a hole (132) are proposed. The hole has concave inner surface (134) on the whole. The bearing assembly includes a bearing (140) with an internal element (142). The internal element is movable around the central axis (A) and its dimensions allows for its location in the hole. The internal element has convex outer surface (144) on the whole which is mating the concave inner surface (134) of the hole. The casing acts as an external element of the bearing.

EFFECT: reduced potential risk of fretting wear and corrosion, decreased weight and complexity of bearing design and decreased dimensions of the casing, as well as improved accuracy of bearing positioning and reduced risk of its displacement.
