ROCKING ASSEMBLY OF CHAMBER OF LIQUID-PROPELLANT ENGINE (LPE) Russian patent published in 2015 - IPC F02K9/66 F02K9/80 

FIELD: engines and pumps.

SUBSTANCE: invention relates to rocking assemblies of a combustion chamber of a liquid-propellant engine (LPE) and can be used for installation of a geometrical axis of the chamber rocking in one plane to the specified position with high accuracy. In the rocking assembly between an inner bearing race and a trunnion there installed is an additional threaded bushing with a flange for a bearing retainer plate, which contacts to the mating thread of the trunnion, in traverses, at bolt installation points, there are holes in the form of oval slots, between bases of the frame and the traverses there are adjustment gaskets from a steel plate installed, between traverses and bolt heads there are installed double support steel washers of increased thickness with holes for bolts; a pin is installed between the threaded bushing and the trunnion.

EFFECT: invention ensures high accuracy of installation of a geometrical axis and a rocking axis of the chamber on the engine relative to a common axis of the engine and its mounting plane; improving attachment reliability of traverses to bases of the frame and excluding rotation of the threaded bushing relative to the trunnion.
