Hydraulic clamping nut for rotating tools, in particular grinding wheels

摘要

In the case of grinding wheels, in particular large-diameter grinding wheels, which are held by hydraulic clamping nuts the problem which arises is that the pressure acting uniformly on the entire grinding wheel can lead to destruction of the grinding wheel. A hydraulic clamping nut is proposed in which the pressure flange consists of an annular foot which is adjoined, through a groove-like indentation guided concentrically to the axis of rotation, by individual pressure-flange sections formed by radially guided indentations and against which the pistons of the hydraulic pressure devices bear.
