Hydraulic nut for mounting conical objects

The invention relates to a hydraulic nut (8) for mounting a hollow object having a conically shaped opening, such as a conical ring (2), on a conical shaft (6), comprising a nut body (9) having an annular, coaxial cavity (10) as well as a ringlike piston (11) which is displaceable within said cavity...

Beschreibung
Zusammenfassung:	The invention relates to a hydraulic nut (8) for mounting a hollow object having a conically shaped opening, such as a conical ring (2), on a conical shaft (6), comprising a nut body (9) having an annular, coaxial cavity (10) as well as a ringlike piston (11) which is displaceable within said cavity (10), wherein measuring means (19, 20, 21, 23) are provided for measuring the axial displacement of the ringlike piston (11) with respect to the nut body (9). To improve the mounting, the invention is characterized in that the measuring means (19, 20, 21, 23) have a measuring pin (19) contacting a reference (18) of the piston (11), which is arranged axially displaceable in an axially extending bore 22 in the nut body (9), wherein the measuring pin (19) is connected to a distance measuring device (20) for measurement of the relative axial displacement between nut body (9) and piston (11).
