FRICTION HYDROSTATIC CLUTCH Russian patent published in 2023 - IPC F16D25/04 F16D15/00 F16D23/14 

FIELD: machine parts.

SUBSTANCE: coupling comprises a movable bushing and a hub, consisting of a bearing part and a shroud part pressed onto it, and at least one circular channel or longitudinal channels is made on the outer surface of the bearing part, separated from its inner surface by a thin wall configured for radial deformation, whereas at least one circular or longitudinal channels are configured for forming a closed cavity after pressing the hub parts to fill it with a working fluid, at least one circular channel with a thin wall configured for radial deformations is made on the outer surface of the shroud part, in which the bodies rolling elements are located protruding above the outer surface of the hub, whereas on the shroud part, the specified movable sleeve is installed, configured for longitudinal movement, the inner surface of which has a lead-in and pressure sections, providing radial movement of the rolling elements, through which radial deformation of the thin wall of the circular channel is ensured, which creates a hydrostatic pressure in the working fluid in a closed cavity, which ensures the deformation of its walls, which ensures their pressing against the mating surface of the shaft and the transfer of the load by friction forces. The longitudinal channels can be located concentrically and united by an annular channel made on the outer part.

EFFECT: greater manufacturability, improved performance.
