Abstract

Improvements in hydraulic decelerators, for braking a shaft end in which the rotor comprises a hollow semi-sheath housing mounted on one end rotatably connected to said shaft end and suitable for passing axially in front of another hollow semi-sheath housing that forms part of a fixed casing or stator that surrounds this rotor, the working liquid being introduced into said rotor housing through its bottom from a central intake chamber located near the axis of this housing and being evacuated from the latter, at the level of its edge of greater diameter, to a peripheral chamber, with facing areas of the outer face of the rotor housing and the inner face of the crankcase being provided so as to form an annular labyrinth with a strangled passage, characterized in that the average diameter of the strangled area (12) of this labyrinth has such a value that the hydraulic thrusts exerted axially p For the working liquid on the two faces of the rotor housing (2) are balanced, the contact between the parts in relative rotation of the decelerator being exclusively limited to the sliding contact between a rigid annular surface (41) integral with one of these parts and an annular sealing gasket 39 supported by the other part.
