REVERSING COMBINATION SUPPORT Russian patent published in 2013 - IPC F16C21/00 

FIELD: machine building.

SUBSTANCE: combination support includes a housing and a rolling bearing and a sliding bearing, which are arranged in it. As one of support surfaces of the sliding bearing in the main operating modes and installation elements for fixation of the outer ring of the rolling bearing there used are elastic metal petals during start-up/stop periods. Petals are hinged on inner surface of the shaft, which can change an inclination angle relative the shaft at the change of rotation direction.

EFFECT: improving reliability and durability of a support by separation and duplication of functions of a rolling bearing and a sliding bearing, as well as increasing damping capacity of the support and enlarging functional capabilities of the unit as a whole owing to using elastic metal petals and automatic correction of their position at the change of the shaft rotation direction.
