HYDROSTATIC BEARING Russian patent published in 2008 - IPC F16C13/02 F16C32/06 B21B31/07 

FIELD: mechanics.

SUBSTANCE: said invention relates to roll mill hydrostatic bearings for rolls, in particular, to hydrostatic bearings with mounting clamping assembly, built-in compactly along the axis. Hydrostatic bearing of the roll has a tapered neck (14), which leads to reduced-diameter end section (20), and comprises an internally tapered sleeve (12), which is fit on the tapered neck (14) of roll (16). Sleeve (12) can rotate in socket (24), secured inside the cushion assembly (26). The bearing also comprises hollow piston (32), mounted on the end section (20) and stationary as regards to the latter, cylinder (38), divided by piston (32) into the first and second chambers (42), (44), ring (46) of the sleeve, which is pressed against the sleeve (12), round thrust component (48) located between two adjacent segments of ring (46) of the sleeve and cylinder (38) and capable to overlap these segments, and a means for alternate pressurising of either the first or the second chamber (42), (44). When the first chamber (42) is pressurised, cylinder (38) moves in axial direction and forces sleeve (12) to its fit position by acting on thrust component (48) and ring (46) of the sleeve. Pressure rise in the second chamber (44) retracts the cylinder (38), so that the latter retracts the sleeve (12) by acting on the cushion assembly (26) and socket (24).

EFFECT: reduced regular costs for the roll mill as a whole.
