SUBMERSIBLE HYDRAULIC BRAKE Russian patent published in 2005 - IPC

FIELD: experimental hydrodynamics.

SUBSTANCE: submergible hydraulic drive has braking disks mounted on hubs instead of axially aligned screw propellers. Two face washers are coaxially mounted at the outer faces of disks with a spaced relation to each other. The washers are interconnected over periphery through ties for permitting axial space to be adjusted. The periphery interface zone of the washers receives rim washers which are mounted to provide an axial space between them and to form a casing with the rim which is penetrable for fluid in the radial direction. The axial space between the faces of the rim washers is equal or less than the thickness of the boundary layer on the face of the braking disk.

EFFECT: enhanced reliability.
